Predator Fauna Associated with Oleander Aphids on Four Milkweed Species and the Effect of Those Host Plants on the Development and Fecundity ofCycloneda mundaandHarmonia axyridis

The oleander aphid, Aphis nerii Boyer de Fonscolombe, feeds on members of the Apocynaceae family, including several Asclepias species and Cynanchum laeve. Milkweeds alongside and within agricultural crops provide opportunities for natural enemies to encounter and feed upon A. nerii. The predator fauna associated with natural populations of A. nerii on four milkweed species was determined. The development and fecundity of two Coccinellidae species, Harmonia axyridis (Pallas) and Cycloneda munda (Say), were investigated in a laboratory. The development of fourth instar Coccinellidae when fed diets containing A. nerii from host plants having a low or high concentration of cardenolides was investigated. Immature beetle survival was generally poor and longevity was not significantly different when fed A. nerii from different host plant species, with similar survival patterns observed for first and fourth instar Coccinellidae larvae. Both H. axyridis and C. munda exhibited a reduced fecundity when fed A. nerii regardless of milkweed host species compared to beetle fecundity when fed a diet of Acyrthosiphon pisum. When provided with mixed diets, larvae consumed significantly more A. pisum than A. nerii. Larvae continued to accept A. nerii even after feeding on the aphid provoked emesis. Observations revealed that a fluid leaked from within wounded aphids temporarily or permanently immobilized lady beetle larvae. The unsuitability of A. nerii for lady beetles and the common association of milkweeds with agroecosystems raises concerns about the possible effects of feeding on this aphid by biological control agents.

May the wild male loose? Male wing fanning performances and mating success in wild and mass-reared strains of the aphid parasitoid Aphidius colemani Viereck (Hymenoptera: Braconidae: Aphidiinae)

Aphidius colemani Viereck (Hymenoptera: Braconidae) is a pan-tropical broadly oligophagous endoparasitoid of many aphids of economic importance, including Aphis gossypii Glover and Myzus persicae (Sulzer). While the trophic interactions occurring among A. colemani and its hosts have been extensively studied, little is known about the male- and female-borne cues that guide mating dynamics. Male wing fanning has been found to play a key role in A. colemani courtship, as successful mounting of females without initial wing fanning has never been observed. In this research, we analyzed wing fanning performance and mating ability of males from three different strains of A. colemani: wasps commercially mass-reared on A. gossypii, wild wasps from parasitized A. gossypii, and wild wasps from parasitized Aphis nerii Boyer de Fonscolombe. Results showed that virgin females did not rely on particular male fanning features during mate choice. Moreover, when A. colemani individuals developed on A. gossypii, no major differences were detected in courtship and mating ability between field collected and mass-reared wasps. In contrast, courtship performance and mating success varied between wild A. colemani males reared on different hosts, with those developing on A. nerii having lower quality wing fanning performance during the mounting attempt phase, and reduced ability to compete for females with other males reared on A. gossypii.

Effects of Milkweed Host Species on Interactions between Aphis nerii (Hemiptera: Aphididae) and Its Parasitoids

The oleander aphid, Aphis nerii Boyer de Fonscolombe, feeds on members of the Apocynaceae family. In Kentucky, A. nerii colonizes several Asclepias species and Cynanchum laeve. The prevalence of milkweeds and A. nerii in Kentucky ecosystems allow natural enemies, including the primary parasitoid Lysiphlebus testaceipes, to utilize this aphid as a resource. The efficacy of L. testaceipes when utilizing A. nerii reared on different host plant species was studied in the field and in the laboratory. In the laboratory, the time until first host contact and the number of ovipositional attempts by L. testaceipes did not vary among aphids from different host plant species. However significantly more aphids were mummified and more parasitoids successfully emerged from aphids on C. laeve than from aphids on tested Asclepias species. The successful emergence rates of L. testaceipes from A. nerii colonizing four species of milkweed were also determined in a naturally infested field plot. While no significant differences were detected in 2009, significantly more L. testaceipes emerged in 2010 from A. nerii mummies collected from C. laeve than from mummies on A. syriaca and A. incarnata with numbers emerging from mummies on A. tuberosa being indistinguishable from those on C. laeve or A. syriaca. Five hyperparasitoid species were also recovered from A. nerii mummies over a two year period. A comparison of hyperparasitoid emergence among A. nerii mummies collected from four species of milkweed found that with the exception of one species during 2009, emergence rates did not differ significantly among aphid host plants. Our results suggest that parasitoid development may be affected by aphid host plant and that adverse effects of A. nerii on L. testaceipes are less severe when aphids develop on C. laeve compared to tested Asclepias species.

Thinking Outside the Asclepias Box: Oleander Aphids and Honeyvine Milkweed

Abstract The oleander aphid, Aphis nerii Boyer de Fonscolombe, feeds on milkweeds in the Apocynaceae family. In Kentucky, A.nerii colonizes several common Asclepias species and honeyvine milkweed, Cynanchum laeve (Michaux). Previous studies investigating whether and how host plant characteristics influence A.nerii fitness have produced conflicting results. Our observations suggested that A.nerii more readily colonized C.laeve than Asclepias species. We hypothesized that aphid fitness differed among host plant species having different characteristics, and specifically, that A.nerii performance would be greatest on host plants having low cardenolide concentrations and few physical defenses. Physical and chemical characteristics were measured on C.laeve and three Asclepias species. Laboratory and field experiments were conducted to compare A.nerii performance among these four milkweed species in the absence of natural enemies. Changes in aphid densities over time were examined in the presence of natural enemies. Plant characteristics and aphid performance were found to differ among milkweed species. In the absence of natural enemies, A.nerii performance was best on C.laeve. When exposed to natural enemies, A.nerii densities remained higher on A.incarnata and C. laeve than on A.syriaca and A.tuberosa. Physical differences between C.laeve, a vining milkweed, and tested Asclepias species may increase suitability of honeyvine milkweed for A.nerii colonization. Our results suggest that C.laeve may rely more on tolerance and less on nonpreference or antibiosis resistance to herbivores.

The effects of temperature for development time, fecundity and reproduction on some ornamental aphid species

The development time, survivorship and reproduction of the Sarucallis kahawaluokalani (Kirkaldy), Eucallipterus tiliae L., Capitophorus elaeagni del Guercio, Aphis nerii Boyer de Fonscolombe, Cinara cedri Mimeur were studied on the Lagerstroemia indica L., Tilia tomentosa Moench, Elaeagnus angustifolia L., Nerium oleander L. and Cedrus libani Loud. at four constant temperatures (20C, 22.5C, 25C and 27.5C). Total nymphal development time ranged from 7.78 d at 22.5C to 9.81 d at 25C of C.elaeagni, 9.32 d at 25C to 12.5 d at 20C of E. tiliae, 7.08 d at 27,5C to 11.14 d at 20C of S. kahawaluokalani, 15.85 d at 25C to 12.57 d at 20C of A. nerii and 13.00 d at 20C to 10.07 d at 25C of C. cedri. The intrinsic rate of increase (rm) at 22.5C had the highest value for S. kahawaluokalani and C. elaeagni (0.5703) and (0.2945) among all tested constant temperatures. The calculated rm was higher at 25C for E. tiliae (1.4124) and C. cedri (0.2975) and at 20C A. nerii (0.2648). That the optimal temperature for E. tiliae and C.cedri on T. tomentosa and C. libani was 25C, for C. elaeagni and E. tiliae was 22.5C on E. angustifolia and T. tomentosa and for A. nerii was 20C on N. oleander.

Phylogenetic relationships of Dysaphis pyri (Boyer de Fonscolombe) and Dysaphis reaumuri (Mordvilko) (Hemiptera, Sternorrhyncha: Aphididae): COI and EF-1α evidence

Dysaphis (Pomaphis) pyri (Boyer de Fonscolombe, 1841) and Dysaphis (Pomaphis) reaumuri (Mordvilko, 1928) are two holocyclic aphid species alternating between Pyrus (Rosaceae) and Galium (Rubiaceae). Comparative phylogenetic analysis was performed using partial mitochondrial cytochrome oxidase subunit I (COI) and nuclear elongation factor 1 alpha (EF-1α) sequences. Partial COI data indicate the possibility of the early divergence in the D. pyri–D. reaumuri stem, which might have occurred even before the splitting of the common ancestral species of the D. reaumuri–D. plantaginea complex. Such a conclusion seems to be compatible with the available data on host specificity, life cycles and distribution of both species. This introductory phylogenetic analysis based on partial COI and EF-1α sequences indicates the need for reconsideration of the subgeneric structure in the genus Dysaphis.

Insects Associated with MilkweedCalotropis procera(Ait.) Ait. in the Ibex Reserve in the Central Region of the Kingdom of Saudi Arabia

The insect fauna of the native milkweed plant Calotropis procera (Ait.) Ait. in the Ibex Reserve, in the Central Region of the Kingdom of Saudi Arabia was studied. Insects were sampled bimonthly from May 2007 to late April 2008, and then irregularly until June 2011. Ninety-nine insect species belonging to eight orders, 43 families and 80 genera were found to have some type of association with the plant during the period of sampling. The carpenter moth, Semitocossus Johannes (Staudinger), scale insect Contigaspis zilla (Hall) and milkweed aphid Aphis nerii (Boyer de Fonscolombe) were pests attacking the plant. Nine taxa collected represent new country records for Saudi Arabia: Clambus sp. (Coleoptera, Clambidae); Angiometopa sp. (Diptera, Sarcophagidae); Steleoneura sp. (Diptera: Tachinidae); Goniurellia longicauda Freidberg (Diptera, Tephritidae); P silochalcis sp. (Hymenoptera, Chalcididae); Odynerus blanchardianus Saussure (Hymenoptera, Chrysididae); Nomioides kenyensis Pesenko & Pauly (Hymenoptera, Halictidae); Cremastus aegyptiacus Szepligeti (Hymenoptera, Ichneumonidae) and Cerceris chlorotica Spinola (Hymenoptera, Sphecidae).

First Report of Alfalfa mosaic virus Infection in Viburnum tinus in Chile.

Viburnum tinus L., commonly known as laurustinus, is an ornamental shrub that is widely used as a garden plant and flower crop. V. tinus is popular because of its desirable characteristics such as evergreen foliage, tolerance to pruning, winter blooms, and its adaptation to cold temperate zones. It is also relatively easy to grow and is commonly used as a windbreak. Infection of this ornamental species by Alfalfa mosaic virus (AMV) has been associated with yellow mottling or variegated leaf coloring, including light green and white, and has been referred to as the "Viburnum Calico" (1,4). In April 2011, at the onset of winter in the Southern Hemisphere, intense yellow spotting and mottling was observed on V. tinus leaves in the San Joaquin Campus at Pontificia Universidad Catolica de Chile. Presence of Aphis spiraecola Patch was observed on the shrubs, however, in the area it is also common to find other aphid species such as Toxoptera aurantii (Boyer de Fonscolombe) and A. fabae Scopoli. Leaf tissue samples from 10 asymptomatic and 10 symptomatic plants were examined for the presence of AMV by tissue-blot immunoassay with a commercially available polyclonal antibody (Agdia Inc., Elkhart, IN) along with the Goat affinity purified anti-rabbit IgG conjugated (Whole Molecule) (Molecular Probes, Invitrogen Corp., Carlsbad, CA). First-strand cDNA synthesis and PCR were performed with specific primers CP-AMV1 and CP-AMV2 (3). AMV was detected in all symptomatic leaves and also in two of the asymptomatic tissue analyzed by tissue blot assay. Reverse transcription (RT)-PCR produced 753-bp amplicons in all samples that were positive to AMV by tissue printing. No amplification product was observed when water control or seronegative samples were used as templates in the RT-PCR assays. Two amplicons were directly sequenced in both directions to confirm the identification of AMV in the leaf samples. The sequences obtained were homologous and BLASTN analysis of the submitted sequence (GenBank Accession No. JN040542) showed 99% nucleotide sequence identity to an AMV isolate described from Nicotiana tabacum L. (GenBank Accession No. FJ527749). These results demonstrate the presence of AMV in V. tinus in Chile. This pathogen has also been described to be affecting V. tinus in France (1) and V. lucidum Mill. in Spain (2). In Chile, V. tinum is increasingly grown as an ornamental plant. Therefore, care should be taken to ensure that the propagative materials of V. tinum are devoid of AMV infection to prevent further spread of this virus.

Monotypic prey-mediated development, survival and life table attributes of a ladybird beetle Anegleis cardoni (Coleoptera: Coccinellidae) on different aphid species

Successful mass production of biocontrol agents is a prerequisite to their effective use in the field. Thus in the present study the suitability of ten aphid species of a ladybird beetle Anegleis cardoni (Weise) in terms of growth, development, survival and mortality life table attributes was assessed for the purpose of mass production. The study revealed that the developmental duration of the immature stages of A. cardoni was shortest when fed on Uroleucon compositae (Theobald), Rhopalosiphum maidis (Fitch), Hyadaphis coriandri (Das) and Myzus persicae (Sulzer) in comparison with other aphid species. Immature survival, development rate, adult weight and growth index were also highest when A. cardoni larvae were fed on these aphids, while lowest when fed on Hysteroneura setariae (Thomas) and Ceratovacuna silvestri (Takahashi). Any larva of A. cardoni did not reach adult stage when fed on Aphis nerii Boyer de Fonscolombe; therefore it may be considered as a toxic prey. Life table data revealed that the overall mortality prior to adult stage was lowest in U. compositae and highest in C. silvestri. The first instars suffered the highest mortality in comparison with other instars on all the aphid species tested. However, the life expectancy for each aphid species as prey revealed a continuous decline with the advancement of age. Thus among all the ten aphid species tested, U. compositae, R. maidis, H. coriandri and M. persicae were found equally suitable for mass production of A. cardoni.

First field records of the sexuales (males and oviparae) of Toxoptera aurantii (Hemiptera: Aphididae)

Toxoptera aurantii (Boyer de Fonscolombe) is an aphid pest of great agricultural importance, not only due to its polyphagy but mostly due to its ability to transmit various plant viruses e.g. Citrus tristeza virus on Citrus (Blackman & Eastop, 2000). Blackman & Eastop (2000) considered this aphid to be entirely anholocyclic, because no sexual morphs have ever been observed in the field.

Seasonal occurrence of aphids and their natural enemies in Satsuma mandarin orchards in Izmir, Turkey

Field surveys were carried to determine the seasonal occurrence of aphids and their natural enemies in four Satsuma mandarin orchards in Izmir, Turkey between January 2006 and November 2007. Aphid species determined included Aphis craccivora Koch, 1854; Aphis gossypii Glover, 1877; Aphis spiraecola Patch, 1914; Myzus (Nectarosiphon) persicae (Sulzer, 1776) and Toxoptera aurantii (Boyer de Fonscolombe, 1841). Predators from the following families were determined: Coccinellidae (Coleoptera), Chrysopidae (Neuroptera), Syrphidae, Cecidomyiidae, and Chamaemyiidae (Diptera). Braconidae (Hymenoptera) parasitoids were reared from field-collected mummies. Aphid numbers fluctuated from early April to the beginning of July and were highest from late April to early June. Several species natural enemies of aphid were found and, when combined with high summer temperatures, negated the need for insecticidal application. Therefore, conservation of natural enemies is an essential component of the management of aphids in Satsuma mandarins in Izmir.

Aphids of the genus Dysaphis Börner (Homoptera, Aphididae) associated with plants of the Monocot classis (Liliopsida)

A detailed description of and key to all the known morphs of five species of the genus Dysaphis, D. allii Daniyarova, D. eremuri (Narzikulov), D. neostroyani Ilharco, D. tulipae (Boyer de Fonscolombe), and D. ubsanurensis Ivanovskaya, living on plants of the class Liliopsida, are given. Morphometrical analysis has shown Dysaphis eremuri baisunensis Narzikulov, 1970 to be merely a synonym of D. tulipae (Boyer de Fonscolombe, 1841).

New Records of Hemiptera (Sternorrhyncha, Cicadomorpha, Heteroptera) for Newfoundland, Canada

Abstract The first Newfoundland records are given for 12 Palearctic species: the aphids Acyrthosiphon caraganae (Cholodkovsky), A. pisum (Harris), Hyperomyzus lactucae (L.), Macrosiphoniella artemisiae (Boyer de Fonscolombe), Pleotrichophorus glandulosus (Kaltenbach), Tuberculatus annulatus (Hartig), and Uroleucon cirsii (L.); leafhoppers Athysanus argentarius Metcalf and Grypotes puncticollis (Herrich-Schaeffer); anthocorids Acompocoris pygmaeus (Fallen) and Anthocoris confusus Reuter; and microphysid Loricula pselaphiformis Curtis. All 12 Old World species are considered immigrant (rather than intentionally introduced) in Newfoundland. Two mirid species native to North America—Deraeocoris piceicola Knight and D. pinicola Knight—also are reported as new to the island. All 14 hemipteran species were collected in the eastern Avalon Peninsula (13 were found at the major port city of St. John's) and were found mainly on Old World plants. The record of the mirid D. piceicola is the first for eastern Canada, a...

Vitex agnus castus and Euphorbia characias ssp. wulfenii as Reservoirs of Aphid Parasitoids (HymenopterA: Braconidae: Aphidiinae)

The role of the self-sown shrubs Vitex agnus castus and Euphorbia characias ssp. wulfenii as reservoirs of aphid parasitoids was investigated. In field studies, V. a. castus grew adjacent to an orchard of Citrus sinensis and E. characias ssp. wulfenii adjacent to an orchard of Prunus dulcis. The relative abundance of the parasitoids of Aphis viticis Ferrari on V. a. castus, Toxoptera aurantii (Boyer de Fonscolombe) on C. sinensis, Aphis euphorbiae Kaltenbach on E. characias ssp. wulfenii and Brachycaudus amygdalinus (Schouteden) on P. dulcis in various parts of Greece was assessed during 1996-2005. Aphidius colemani Viereck predominated on A. viticis and T. aurantii in all sampling cases. In contrast, Ephedrus persicae Froggatt was the dominant species parasitizing A. euphorbiae on E. characias ssp. wulfenii and B. amygdalinus on P. dulcis. Furthermore, to illustrate the agro-ecosystem relationships through the reservoirs, we present the distribution and host range patterns of parasitoids associated with aphids on V. a. castus and Euphorbia spp. in southeastern Europe. A key for the identification of aphid parasitoids on V. a. castus and Euphorbia spp. is provided.

Mass production, releasing and evaluation of the lady beetle, Coccinella undecimpunctata (Coleoptera: Coccinellidae), for control of aphids in Egypt

Coccinella undecimpunctata L. (Coleoptera: Coccinellidae) is one of the most effective bioagents for control of aphids in Egypt. The present work deals with mass production, releasing and evaluation of this predator on different aphid pests including Aphis gossypii Glover on cotton, Brevicoryne brassicae (L.) on cabbage, Aphis craccivora Koch on potato, Myzus persicae (Sulzer) on apple, Aphis nerri (Boyer de Fonscolombe) on oleander and Pterochloroides persica Chlod. on peach. Experiments were carried out in four different locations of Egypt including Qalubiya, Demmyate, North Sinai and Giza. About 2.22 million eggs were released, biweekly, during 2003 – 2004. Eggs were assessed monthly during 2004 by counting aphid stages and larva and pupa of C. undecimpunctata. The results show that the populations of aphid species decreased from 3115 – 11, 1062 – 315, 2110 – 28, 1945 – 310, 1152 – 310 and 4350 – 76 individuals/10 leaves on cotton, apple, cabbage, peach, potato, oleander, respectively after releasing C. undecimpunctata. Significant reductions in some aphid predators and parasitoids also occurred.

Molecular data reveal convergent reproductive strategies in iceryine scale insects (Hemiptera: Coccoidea: Monophlebidae), allowing the re‐interpretation of morphology and a revised generic classification

Abstract The scale insect tribe Iceryini (Coccoidea: Monophlebidae) is a group of relatively large and polyphagous insects found worldwide. Currently, the tribe contains about 80 named species placed in seven genera, which are diagnosed largely on features associated with egg protection. We reconstruct the phylogeny of the Iceryini on the basis of nucleotide sequence data from nuclear ribosomal (18S and D2, D3 and D10 regions of 28S) and protein‐coding (histone H3) gene regions of 40 iceryine species representing six of the seven genera and seven outgroup taxa, mostly from two other tribes of Monophlebidae. Bayesian and maximum parsimony analyses recover a monophyletic tribe and clades that correspond more to geography than to the existing morphology‐based classification. Gueriniella Fernald is sister to the rest of the Iceryini and the genera Crypticerya Cockerell, Icerya Signoret and Steatococcus Ferris are not monophyletic. Our data imply that the distinctive iceryine reproductive strategies, such as protecting eggs in a waxy ovisac or inside a marsupium, are poor indicators of relationships. On the basis of molecular relationships and the re‐examination of morphological characters, we recognize only five genera of Iceryini –Crypticerya, Echinicerya Morrison, Gigantococcus Pesson & Bielenin, Gueriniella and Icerya – and substantially revise the generic concepts of Crypticerya, Gigantococcus and Icerya. We provide a key to the genera based on adult females. We redescribe and illustrate the adult female and first‐instar nymph of the type species Crypticerya rosae (Riley & Howard), Echinicerya anomala Morrison, Gigantococcus maximus (Newstead) (adult female only), Gueriniella serratulae (Fabricius) and Icerya seychellarum (Westwood). We recognize Auloicerya Morrison as a junior synonym (syn.n.) of Icerya, and transfer the two Auloicerya species to Icerya as I. acaciae (Morrison & Morrison) comb.n. and I. australis Maskell comb.rev. We recognize Steatococcus and Proticerya Cockerell as junior synonyms (syn.n.) of Crypticerya. From Steatococcus, we transfer five species to Crypticerya [C. mexicana Cockerell & Parrott comb.rev., C. morrilli (Cockerell) comb.n., C. tabernicola (Ferris) comb.n., C. townsendi Cockerell comb.rev., C. tuberculata (Morrison) comb.n.], four species to Gigantococcus [Gi. euphorbiae (Brain) comb.n., Gi. gowdeyi (Newstead) comb.n., Gi. madagascariensis (Mamet) comb.n., Gi. theobromae (Newstead) comb.n.] and three species to Icerya [I. assamensis (Rao) comb.n., I nudata Maskell comb.rev., I. samaraia (Morrison) comb.n.]. From Icerya, we transfer 14 species to Crypticerya [C. brasiliensis (Hempel) comb.n., C. colimensis (Cockerell) comb.n., C. flava (Hempel) comb.n., C. flocculosa (Hempel) comb.n., C. genistae (Hempel) comb.n., C. littoralis (Cockerell) comb.n., C. luederwaldti (Hempel) comb.n., C. minima (Morrison) comb.n., C. montserratensis (Riley & Howard) comb.n., C. palmeri (Riley & Howard) comb.n., C. rileyi (Cockerell) comb.n., C. similis (Morrison) comb.n., C. subandina (Leonardi) comb.n., C. zeteki (Cockerell) comb.n.] and nine species to Gigantococcus [Gi. alboluteus (Cockerell) comb.n., Gi. bimaculatus (De Lotto) comb.n., Gi. brachystegiae (Hall) comb.n., Gi. longisetosus (Newstead) comb.n., Gi. nigroareolatus (Newstead) comb.n., Gi. pattersoni (Newstead) comb.n., Gi. schoutedeni (Vayssière) comb.n., Gi. splendidus (Lindinger) comb.n., Gi. sulfureus (Lindinger) comb.n.]. From Crypticerya, we transfer seven species to Icerya [I. clauseni (Rao) comb.n., I. jacobsoni Green comb.rev., I. jaihind (Rao) comb.n., I. kumari (Rao) comb.n., I. mangiferae (Tang & Hao) comb.n., I. natalensis (Douglas) comb.rev., I. nuda Green comb.rev.] and five species to Gigantococcus [Gi. bicolor (Newstead) comb.n., Gi. cajani (Newstead) comb.n., Gi. caudatus (Newstead) comb.n., Gi. ewarti (Newstead) comb.n., Gi. rodriguesi (Castel‐Branco) comb.n.]. Both I. hyperici (Froggatt) and Palaeococcus dymocki (Froggatt) are syn.n. of I. nudata (all previously placed in Steatococcus). We recognize I. maynei Vayssière as a syn.n. of Gi. nigroareolatus, I. tremae Vayssière as a syn.n. of Gi. schoutedeni and I. townsendi plucheae Cockerell as a syn.n. of C. townsendi. We revalidate the species name I. crocea Green stat.reval. In addition, we transfer I. taunayi Hempel to Laurencella Foldi (Monophlebidae: Llaveiini) as L. taunayi (Hempel) comb.n. Four species, Coccus hirticornis Boyer de Fonscolombe, I. chilensis Hempel, I. insulans Hempel and I. paulista Hempel, are considered incertae sedis. We designate lectotypes for C. rosae, E. anomala and I. candida (a junior synonym of I. seychellarum). Following this revision, we recognize 74 species of Iceryini, distributed as follows: 22 in Crypticerya, one in Echinicerya, 19 in Gigantococcus, two in Gueriniella and 30 in Icerya.
