Plant - Animal Association in Relation to Grouse Locusts (Orthoptera: Tetrigoidea)

The grouse locusts are very much inter-related with the plants. The paper discusses interection of these insects with plants and the effect has been studied in laboratory experiments and found some mosses, fungi, algae, Oriza sativa (Paddy) and some sprouting cereals act as common feed. The structural modifications in their mandibles are specialized to make them functional with the type of feed they take.

ORTHOPTERAN DIVERSITY IN TROPICAL ECOSYSTEMS OF CENTRAL KERALA, INDIA

Orthoptera is a diverse arthropod taxon that includes locusts, grouse locusts, short-horned grasshoppers, long-horned grasshoppers, katydids, crickets and mole crickets. They play crucial roles in food chains, nutrient cycling and pollination. The diversity of orthopterans in agroecosystems and grasslands located in the highlands and lowlands of Central Kerala were studied from December 2019 toMarch 2020. The study was conducted in Avoly of Ernakulam District and Venmony of Idukki District in Kerala by employing random sampling in 10 x10 m quadrats. A total of 35 species of orthopterans, belonging to two suborders, 10 families, 20 subfamilies, and 33 genera were recorded. Family Acrididae with fourteen species was the most dominant family followed by Tettigoniidae. Two species namely, Chitaura indica and Burrinia burri are endemic to the state of Kerala. It was found that the ranges of most of the orthopteran genera reported in our study extend all over the South East Asian countries. The highest number of Orthoptera was reported in December in both locations and it decreased towards March. Simpson’s diversity index value shows that both regions harbour a highly diverse orthopteran community. The diversity index value of Venmony is comparatively higher which might be due to the proximity of the study site to the natural forest ecosystem and fewer disturbances. More studies on the orthopteran fauna of Kerala are recommended which would help control their pest status and exploit their economic potential as food in animal husbandry

New taxa of pygmy grasshoppers from Australia with notes on classification of the subfamily Batrachideinae (Orthoptera: Tetrigidae)

The pygmy grasshopper subfamily Batrachideinae consists of three tribes: Batrachideini Bolívar, 1887; Cassitettigini Yin, 1984, nom. resurr.; Bufonidini Hancock, 1907, nom. resurr., stat. nov. The Australian pygmy grasshoppers of the tribe Bufonidini are reviewed. Three new genera are described, namely Paraselina gen. nov. (type species Vingselina multifora Rehn, 1952), Anaselina gen. nov. (type species Vingselina minor Sjöstedt, 1921), and Selivinga gen. nov. (type species Selivinga tribulata sp. nov.). Four new combinations are proposed: Paraselina multifora (Rehn, 1952), comb. nov.; P. trituberculata (Sjöstedt, 1932), comb. nov.; P. brunneri (Bolívar, 1887), comb. nov.; Anaselina minor (Sjöstedt, 1921), comb. nov. A key to Australian genera of Batrachideinae is provided.

The Order Orthoptera includes short horned and long horned grasshoppers, crickets and grouse locusts. These insects range from sizes less than 5 mm to 115 mm. They are distributed worldwide and mainly in warmer regions and are in the temperate zone. They are found in all terrestrial habitats from subterranean burrows and caves to tree tops, and from dense forest to savanna and deserts. Most of them are phytophagus. The order Orthoptera is one of the largest having over 20,000 species worldwide with about 10% of the total world species (1,750 species) recorded from India (Hirdesh Kumar and Mohd. Kamil Usmani, 2014). The paper presents the checklist and diagnostic characters of orthoptera of Kanchipuram district along with their known distribution which includes 12 species/subspecies of belonging to 9 genera under 2 Suborder, 3 Superfamilies, 3 families and 7 subfamilies.

The mitochondrial genome of the Chinese special butterfly Luehdorfia chinensis Leech (Lepidoptera: Papilionidae)

Luehdorfia chinensis is a poorly known species restricted to certain eastern provinces in China. We have determined the complete mitochondrial genome of a species of grouse locust, L. chinensis. The 13,860 bp long L. chinensis genome contained 12 protein-coding genes: ATP6, ATP8, COI–COIII, partial ND2, ND3–ND6, ND4L, and Cytb; 2 ribosomal RNAs (rRNAs) (partial 12S rRNA and 16S rRNA); and 18 transfer RNAs. These genes identified are present in the same order and orientation as the completely sequenced mitogenomes of other lepidopteran species. The sequence for COI in L. chinensis starts with ATTTAG and ends with TAA.

The complete mitochondrial genome of grouse locust Tetrix japonica (Insecta: Orthoptera: Tetrigoidea)

We have determined the complete mitochondrial genome of a species of grouse locust, Tetrix japonica. The total length of the T. japonica mitogenome is 15,128 bp with 75.57% A+T content. It consists of 13 protein-coding, 22 transfer RNA (tRNA), and 2 ribosomal RNA (rRNA) genes, and an A+T-rich region. The A+T-rich region was located between the small rRNA and tRNA-Ile genes and is 531 bp in length.

Significance of haemolymph protein patterns in biosystematic studies of some grouse locusts (Tetrigidae: Orthoptera)

The grouse locusts (Tetrigidae) represent a group of small sized Caeliferan Orthoptera. These are considered to be primitive orthopterans related to Tridactylids on one hand to Acridids on the other. This family is represented in Indian subcontinent by about 90 species belonging to 35 genera. In the present study haemolymph protein profiles from 7 species from this family have been studied as an additional parameter to understand interrelationship amongst them. It is noted that the speciesParatettix dorsifer andEuparatettix personatus belonging to the same subfamily Tetriginae show remarkable similarity in the haemolymph protein profile, thus justifying their classical taxonomical grouping. In case of subfamily Scelimeninae, however, of the 4 species studied 3 species vizEucriotettix flavopictus, Criotettix latifrons andThoradonta pruthii show a marked similarity, howeverEucriotettix harpago shows a pattern closer to that observed in the subfamily Cladonotinae. This implies that though by classical taxonomic criteria the 4 species are close to each other this may not be a very natural grouping.

Some observations on the nutrition—reproduction correlation in grouse locusts (Orthoptera: Tetrigidae)

The correlation between nutrition and reproduction with reference to two grouse locusts,Euscelimena harpago (Tetrigidae: Scelimeniae) andPotua sabulosa (Tetrigidae: Cladonotinae) is assessed. As far asEuscelimena harpago is concerned the impact of nutrition on reproduction is presented with reference to ovarian development in certain nymphal stages and in the adult. On the other hand, the impact is evaluated from an altogether different angle as far asPotua sabulosa is concerned. This pigmy locust prefers moss as food and tides over winter and hazardous summer as adult. During this period it almost does not feed. This peculiar feature is used as a parameter to assess the nature of impact inP. sabulosa.

MARGINAL POPULATIONS OF CEPAEA NEMORALIS (L.) ON THE BRENDON HILLS, ENGLAND. II. VARIATION IN CHIASMA FREQUENCY.

In different species genetic recombination and the release of variation may be regulated in different ways and at different levels of organization since the components of the control system do not necessarily act in the same direction (e.g., Grant, 1958). For example, in herbaceous plants short generation times promote the release of variability and are often associated with low chromosome numbers: a restrictive device (Grant, 1958). The recombination system within a population may similarly be adjusted so that there is a balance between immediate fitness and long-term adaptability (Carson, 1955a). In populations of an outbreeding organism an important level of genetic control may be through the regulation of chiasma frequency since, given sufficient heterozygosity, a raised chiasma frequency will lead to an increase in the range of gametic genotypes. Differences in chiasma frequencies between populations are therefore possibly adaptive, perhaps reflecting differing ecological circumstances under which these populations exist. In Drosophila the frequency of inversion heterozygotes, in which crossing over is restricted, is important in determining the level of recombination within a population. In certain species, particularly D. robusta and D. willistoni, the amount of inversion heterozygosity decreases as the margins of the species' ranges are reached. In a series of papers (da Cunha et al., 1950; Townsend, 1952; da Cunha et al., 1959) the view was advanced that the degree of chromosomal polymorphism is a function of the variety of ecological niches in the territory which a population inhabits. Carson (1955a, b, 1956, 1964), however, suggested that greater chromosomal homozygosity at the margins serves to allow more recombination which is necessary to provide sufficient flexibility for adjustment to suboptimal conditions. He has also shown (Carson, 1958) that the response to selection in strains originating from marginal populations is greater than that in strains originating from central ones, perhaps reflecting the occurrence of more recombination in the former populations. A completely different situation occurs in the grasshopper Myrmeleotettix maculatus. The presence of B chromosomes has been shown to raise both the frequency and the variance of chiasmata in those individuals which contain them (Barker, 1960; Hewitt and John, 1967). The frequency of B-containing individuals varies between populations and it has been shown that this variation is related to climatic factors such as temperature and rainfall (e.g., Barker, 1966, Hewitt, 1973). Central populations in favorable (warm, dry) environments possess more B chromosomes and have higher chiasma frequencies than more marginal populations in stringent (colder, wetter) localities which have no B chromosomes. A comparable situation may occur in the grouse locust Tettigidea lateralis where Fontana and Vickery (1973) found that the effect of B chromosomes in a marginal population was to change chiasma position with the net effect of depressing recombination. Cepaea nemoralis (L.) has a haploid number of 22 chromosomes (Perrot, 1938). There is a large metacentric pair forming the A group, a medium sized pair, the B

The Genetics of the Grouse Locust Tettigidea parvipennis Harris

The color and morphological patterns of the grouse locust Tettigidea parvipennis Harris, have been used in analysing their genetic constitution. Bellamy (1917) (1) and MacQueen (unpublished thesis, 1938) (2) have reported previous investigations. The breeding method used by Nabours (3) with other species of grouse locusts has been followed. Individuals containing the patterns to be analysed were mated to others with contrasting patterns and the segregation showing in the offspring was recorded. The earliest hatches recorded appeared thirteen days after mating. The offspring were counted and transferred to new jars soon after hatching. The males were separated from the females after the first male became adult, approximately one week in advance of female maturity and four weeks from the time of hatching. The color pattern and wing length records were made with adults because only after the final ecdysis could the length of the wings be determined. The patterns studied are as follows (in their respective chromosomal groups): +/+-wild type, a grayish-black color with a crisscross marking; acts as complement to other color patterns in completing Mendelian ratios.

Crossing-over in the Land Snail Cepæa nemoralis, L

A GENETIC situation of particular interest from the point of view of the evolutionary modification of genetic phenomena occurs, not only among fishes (Lebistes, and other genera), but also among insects (Orthoptera), and land snails (Cepœa), in all of which a number of variant genes, completely dominant to their recessive allelomorph, are found to be closely linked in the same linkage groups. In the grouse locusts, the linkage was so close as to be equivalent to a single allelomorphic series. The occurrence of an outlier of the main group showing only moderate linkage with it was demonstrated by Haldane in the extensive data published by Nabours. Nabours has since shown that in one American species of grouse locust (Acrydium arenosum) a similar series of pattern factors occurs, showing high frequencies of crossing-over.

PARTHENOGENESIS AND THE INHERITANCE OF COLOR PATTERNS IN THE GROUSE LOCUSTPARATETTIX TEXANUSHANCOCK

1. There is indication of a genetic factor, or a group of complementary factors responsible for parthenogenesis in these grouse locusts.2. The hypothesis of Peacock and Harrison (1925, 1926) that parthenogenesis is consequent upon hybridity is probably further supported if it be provided, as these authors did not, that it is necessary to bring together in the processes of hybridism the specific complementary, or climaxing genetic factors which may cause the development of unfertilized eggs.3. The members of the species Paratettix texanus Hancock are bisexual, the fertilized eggs producing males and females in equal numbers, and parthenogenetic, the unfertilized eggs, with rare exceptions, hatching females.4. A mated female may have part of her ova fertilized, and also produce from unfertilized ova, by parthenogenesis, an additional number of offspring which are nearly always females.5. The segregation and crossing over of factors occur in individuals reproducing by parthenogenesis to the same extent as in those reproducing bisexually.6. If fertilized, the egg proceeds with the second polocyte division and develops bisexually. In the absence of the fertilizing sperm the last polyocyte division does not occur, or if it does the polar body is not eliminated. If the specific complementary gene, or genes responsible for initiating parthenogenesis be present, diploidy is retained, or restored, and development may begin, consequentially as a kind of artificial parthenogenesis.7. The progeny from unfertilized eggs are usually homozygous for all the factors they carry, though rarely one proves to be heterozygous for factors.
