New record of Hyperteles (Hymenoptera: Eulophidae) species from Transcaucasia

All three species classified in Hyperteles Förster, 1856 (Hymenoptera: Eulophidae) are recorded from Georgia. Hyperteles luteus (Ratzeburg, 1848) and H. collega (Ratzeburg, 1844) are recorded from Transcaucasia and from Georgia for the first time. A diagnosis of the genus is provided to distinguish it from other genera belonging to subfamily Tetrastichinae.

The first record of Pronotalia Gradwell, 1957 (Hymenoptera, Eulophidae) Wasps from Georgia

Four species of Pronotalia Gradwell (Hymenoptera, Eulophidae: Tetrastichinae) are recorded from the Lagodekhi Reserve (Georgia). Formerly, only P. carlinarum (Szelenyi et Erdos) was known from Transcaucasia (Armenia) (Kostjukov, 1978). Pronotalia fiorii (Domenichini), P. orobanchiae Graham, and P. trypetae Gradwell are recorded for Georgia and Transcaucasia for the first time. In addition to these species, only 4 species are known from Europe and Anatolia: P. erzurumica Doganlar, P. hungarica (Erdos), P. inflata Graham, and P. tortumensis Doganlar; thus, 50% of Pronotalia species from Europe and Anatolia occur in the Lagodekhi Reserve.

Determination of the natural mortality factors of Citrus leafminer, Phyllocnistis citrella Stainton (Lepidoptera: Gracillariidae) in Adana Province, Turkey

In this study, natural mortality factors of Citrus Leafminer, Phyllocnistis citrella Stainton (Lepidoptera: Gracillariidae) were investigated under field conditions. The studies were carried out in a lemon orchard in Adana, Turkey during 2007-2008. Ten trees were selected and weekly one shoot from each tree, and a total of ten shoots, were collected randomly during May-November. In the laboratory, the first 15 leaves were checked using a binocular microscope. All biological stages of the pest and the parasitoids, dead or infected individuals, and empty mines, were counted. According to the method and symptoms of predation, the mortality factors of the pest were recorded. In 2007 and 2008, large numbers of larvae were parasitized (46.25% and 48.12%, respectively). The larval parasitoid Citrostichus phyllocnistoides Narayanan (Hymenoptera: Eulophidae) was the abundant species in both years. The third instar of the host had the highest percent of parasitized individuals. In the first year, 15.33% of the pest were consumed by spiders, 10.07% by Chrysoperla carnea (Stephens) (Neuroptera: Chrysopidae) and 3.14% by ants, whereas in the second year these ratios were 16.61%, 8.57% and 3.78%, respectively. Second instar larvae were the most preferred stage for predation. In 2007, in 13.66% of the mines no pests were recorded, whereas the mortality source of 5.19% of the larvae and pupae was not detected. In 2008, these ratios were 10.21% and 6.87%, respectively. It was determined that predators are as effective as the parasitoids in the biological control of the pest.

Turunçgil yaprak galerigüvesi, Phyllocnistis citrella Stainton (Lepidoptera: Gracillariidae) ile parazitoiti Citrostichus phyllocnistoides Narayanan (Hymenoptera: Eulophidae) arasındaki konukçu-parazitoit ilişkileri

In this study, larval stages of Citrus leafminer, Phyllocnistis citrella Stainton (Lepidoptera: Gracillariidae), which Citrostichus phyllocnistoides Narayanan (Hymenoptera: Eulophidae) prefers for parasitization and its functional and numerical responses were studied in 2008-2009. The larval stage preference studies were conducted in conditions with I., II. and III. larval stages of the pest together and each larval stages seperateIy in the cages. Determination of functional response was studied with mated one day old female parasitoids with 5, 10, 15, 20, 25, 30, 35 and 40 P. citrella larvae density. In numerical response studies, 2, 4, 6, 8, 10 ve 12 individuals of mated one day old C. phyllocnistoides females were released to potted seedlings which had 30 P. citrella larvae on it. It was conducted that C. phyllocnistoides mostly preferred the III. larval stage for egg laying both all P. citrella larval stages seperate or together. In reply to increasing host population density, the number of eggs laid by parasitoid increased parallel to increasing host density until 30 host individuals. The speed of the laying egg became slower over this level. It was determined that the parasitoid demonstrated a Holling type II functional response to increasing host density. According to Holling’s disk equation, searching rate (a) and the handling time (Th) coefficients of the parasitoid were 0.571 h-1 and 0.0997 h, respectively. In numerical response studies, the maximum parasitization was determined at six parasitoid density with 16.53±0.22 individuals

Adaptive radiation and diversification in gall‐inducing insects in the Indian subcontinent: search for a pattern

The most striking behaviour among gall-inducing insects is that a majority of them are specialist organisms that display a high level of fidelity to their host plants. In a context of discussing species diversity among and richness of gall-inducing insects, this paper attempts to discuss the patterns of adaptive radiation evident in different gall-inducing insects of the Indian subcontinent, which is characterized by profound geological, vegetation, and climatic variations. As a case study, in this paper I have analyzed and discussed patterns of adaptive radiation apparent in gall-inducing Cecidomyiidae on Indian Anacardiaceae with a particular reference to Mangifera indica. The possible absence of resistance-breaking genes in Indian Cecidomyiidae on different Anacardiaceae and M. indica explains why these elements have not radiated and diversified as aggressively as the gall-inducing Eulophidae have done on different Eucalyptus taxa introduced into India as commercial plantation crops. Alternatively, the host-plant populations are, in high likelihood, restricting the gene flow between specific gall-midge populations, through their secondary chemistry because, the host-plant mediated impediments on the breeding behaviours impact on the radiation of gall-inducing insects. A significant majority of Indian gall-inducing insects show features of conservative diversification, and based on available evidence their conservative diversification appears to be strongly plant mediated.

A new species of the genus Tetrastichus Haliday (Hymenoptera: Eulophidae), parasitoid of Kokujewia ectrapela Konow (Hymenoptera: Argidae) in Iran

Tetrastichus kokujewiae sp. nov. (Hymenoptera: Eulophidae) is described from Iran. It was reared from pupa of Kokujewia ectrapela Konow, 1902 (Hymenoptera, Argidae). T. kokujewiae is a gregarious parasitoid developing in the cocoons of sawfly.

Effect of sun-exposure of the horse chestnut (Aesculus hippocastanum L.) on the occurrence and number of parasitoids of the horse chestnut leafminer (Cameraria ohridella Deschka & Dimic) in central Poland in 2004- 2006

The research on parasitoids of the horse chestnut leafminer (Cameraria ohridella Deschka & Dymic, 1986) of the order Hymenoptera was conducted in the years 2004– 2006 in six locations in central Poland. The complex of parasitoids was composed of 14 species. Minotetrastrichus frontalis (Nees) and Pnigalio agraules (Walker), (Hymenoptera: Eulophidae) were the dominant species in all locations. It was noted that sun-exposure of the horse chestnut (Aesculus hippocastanum L.) had a significant effect on abundance of parasitoids attacking the horse chestnut leafminer and their percentage share over the study period. The greatest number of parasitoids was found in the trees which were most exposed to sunray penetration, thus the warmest.

Bioecology of Sympiesis hyblaeae Surekha (Hymenoptera:Eulophidae) a Parasitoid of the Teak Defoliator, Hyblaea puera Cramer (Lepidoptera:Hyblaeidae)

The biology, behaviour and seasonal dynamics of Sympiesis hyblaeae (Hymenoptera: Eulophidae) an ectoparasitoid of the teak defoliator, Hyblaea puera (Lepidoptera: Hyblaeidae) are discussed. S. hyblaeae prefers to lay eggs on first or second instar teak defoliator larvae. A single egg is deposited on each host larva. Each female lays an average of 5 eggs per day and an average of 15 eggs during its lifespan. The total developmental period is about 10-13 days. A high proportion (94%) of the pupae formed during the months, December to January are observed going through a diapause period ranging from 111-156 days, with an average of 13S days. The peak activity period of S. hyblaeae in the field is during September to December, which does not coincide with the peak incidence period (April-June) of its host ( H. puera ). The seasonal incidence pattern indicates that S. hyblaeae is not a potential natural biocontrol agent of the teak defoliator.
