Lisotrigona darbhaensis sp. nov. and L. kosumtaraensis sp. nov from Chhattisgarh and Maharashtra states, respectively, are described along with the additional description of the male of L. chandrai. Lisotrigona darbhaensis nested in the tree trunk of teak (Tectona grandis) while L. kosumtaraensis in the Indian frank incense (Boswellia serrata) and Indian boxwood (Gardenia latifolia). Brood cells of L. kosumtaraensis were arranged in clusters. The colony of L. kosumtaraensis consisted of 921 female and 40 male bees. The detailed studies on male genitalia, metasomal sterna, and morphometry with associated female bees collected from Maharashtra and Chhattisgarh provided conclusive evidence as these bees were found different from the known species of Lisotrigona and new to science. Both the new species are distinct and different from other known species of Lisotrigona. The diversity of Lisotrigona bees in India is rich with six valid species and the action of synonymizing all Indian species of Lisotrigona with L. cacciae is arbitrary.

Experiments were conducted to study the life history traits of Spodoptera litura under controlled environmental conditions on groundnut host. To construct the age-specific fecundity life tables, adults emerged on the same day were caged for oviposition and the number of eggs laid on each day was recorded. The key mortality factors involved in each life stages were also accounted. Females contributed highest number of progeny (mx = 346.12) on 39th day of pivotal age. The net reproductive potential (Ro) was 858.52 females/female/generation with the mean generation period (Tc) of 38.86 days. The life table analysis revealed that the late instar larvae were more vulnerable to natural mortality factors (64.95%) and total mortality per cent recorded was 83.02. The various key mortality factors viz., parasitoids (Cotesia sp., Chelonus sp. and Tachinids), virus (NPV), malformed pupa and adults were recorded from the field population of S. litura from groundnut ecosystem.

The objective of this work was to determine the effects of different stages of mulberry leaves on growth performance of treated larvae of Bombyx mori L. (Lepidoptera, Bombycidae) and characters of the resulted cocoons were evaluated. Results showed that the food consumption rate and assimilation rate were greatest for larvae fed on tender and over matured mulberry leaves as compared to larvae fed on mature leaves. Assimilation and conversion efficiencies were very high in the larvae grown on matured mulberry leaves (0.189 and 1.99% respectively). Moreover, the larvae fed on matured mulberry leaves showed higher growth rate, cocoon weight and shell ratio. Among the three different growth stages of leaves, the matured leaves were found to be the best food for final instar larvae of Bombyx mori L. which promotes maximum larval growth and it gains to quality cocoon and raw silk production.

Nonartha birmanicum (Jacoby) from the tribe Aliticini, is reported on mango for the first time. The chrysomelid beetles were found in abundance; nearly around 60 to 90 numbers on a panicle in full bloom stage. The beetle population was spotted particularly during the month of November, on the panicles in full bloom. These are bluish-black minute beetles and were noticed feeding mainly on pollen.

The combined use of chemical insecticides with fungicides and fertilizers in a single application is a promising pest-control option to maximise productivity and minimize labour efficiency. Studies were conducted to assess the compatibility of systemic insecticide, carbosulfan 25 EC with a fungicide, micronutrient and insecticide in brinjal ecosystem. The optimum and effective dose of carbosulfan (250 g a.i.ha-1) was compatible with other agro chemicals used in combination viz., copper oxy chloride 50 WP @500 g a.i.ha-1, zinc sulphate 0.5 per cent and dimethoate 30 EC @ 300 g a.i.ha-1, without any creaming matter and/or sediment formation in any of the combinations. The tank mix foliar application of the combination chemicals viz., carbosulfan @ 250 g a.i.ha-1 + copper oxy chloride 50 WP @ 500 g a.i.ha-1, carbosulfan @ 250 g a.i.ha-1 + zinc sulphate 0.5 per cent and carbosulfan @ 250 g a.i.ha-1 + dimethoate @ 300 g a.i.ha-1 did not inflict any phytotoxic effect on the treatment imposed plants and a mean grade of ‘1’ (0-10% injury) was awarded to all the treated plants in the brinjal ecosystem. The bioefficacy trials after two rounds of spraying with carbosulfan and combination with fertilizer and fungicides revealed that maximum per cent reduction is noticed in insecticide combination (carbosulfan @ 250 g a.i.ha-1 + dimethoate @ 300 g a.i.ha-1) as well as recommended and four times the dose of carbosulfan (250 and 1000 g a.i.ha-1), which similarly effects in managing the shoot and fruit damage caused by the shoot and fruit borer, Leucinodes orbonalis. The treatments with fertilizer and fungicides alone marked the least reduction in fruit and shoot damage. The yield of brinjal ranged from 24.1to 28.7 t ha-1 in different treatments. Plots treated with carbosulfan @ 250 g a.i.ha-1 + dimethoate @ 300 g a.i.ha-1recorded the highest fruit yield (28.7 t ha-1) followed by carbosulfan @ 250 g a.i.ha-1 + copper oxy chloride @ 500 g a.i.ha-1 (28.3 t ha-1) and carbosulfan @ 250 g a.i.ha-1+ zinc sulphate (27.8 t ha-1). The current findings states that carbosulfan in combination with other agrochemicals have given better results in terms of phytotoxicity, bioefficacy and yield.
化学杀虫剂与杀菌剂和化肥在一次施用中联合使用是一种很有前途的防治虫害选择，可最大限度地提高生产率，最大限度地降低劳动效率。研究了系统杀虫剂硫丹25 EC与杀菌剂、微量营养素和杀虫剂在茄子生态系统中的配伍性。硫丹的最佳有效剂量(250 g a.i.ha-1)与其他农用化学品组合使用，即氯化氧化铜50 WP @500 g a.i.ha-1，硫酸锌0.5%和乐果30 EC @ 300 g a.i.ha-1，在任何组合中都没有任何乳化物质和/或沉积物形成。槽内混合叶面施用组合化学品，即碳硫丹@ 250 g a.i.ha-1 +氯化铜50 WP @ 500 g a.i.ha-1，碳硫丹@ 250 g a.i.ha-1 + 0.5%硫酸锌和碳硫丹@ 250 g a.i.ha-1 +敌敌畏@ 300 g a.i.ha-1，对处理植物没有任何植物毒性作用，并且对所有处理植物的平均等级为“1”(0-10%伤害)。在喷施两轮磺胺并与化肥和杀菌剂联合使用后进行的生物功效试验表明，在杀虫剂组合(磺胺@ 250克a.i.ha-1 +乐果@ 300克a.i.ha-1)以及推荐剂量和四倍剂量的磺胺(250克a.i.ha-1和1000克a.i.ha-1)中，最大限度地减少了百分之百，这对管理由芽部和果实螟虫造成的芽部和果实损害也有同样的效果。单独施用化肥和杀菌剂对果实和茎部的损害减少最少。不同处理的茄子产量在24.1 ~ 28.7 t hm -1之间。用硫丹250 g a.i.ha-1+乐果300 g a.i.ha-1处理的产量最高(28.7 t ha-1)，其次是硫丹250 g a.i.ha-1+氯化铜500 g a.i.ha-1 (28.3 t ha-1)和硫丹250 g a.i.ha-1+硫酸锌(27.8 t ha-1)。目前的研究结果表明，在植物毒性、生物功效和产量方面，碳硫丹与其他农用化学品联合使用具有更好的效果。

Initially, three termite sampling methods were compared in a coastal area of North Kerala to check the efficiency of the widely followed standardized belt transect protocol (Jones and Eggleton, 2000) with a simplified belt transect protocol and random search method. Of the total 11 species that belong to 4 genera collected during the study, the standardized belt transect protocol recorded only two genera and 5 species in 20 hours of sampling effort, while the simplified protocol with half the effort (10 hours) recorded two genera and 4 species. Random search method with least effort (6h) recorded 4 genera and 11 species that included all the species collected in the earlier methods. There was a marked difference in sampling efficiency; the random sampling method yielded 1.87 species per hour while standardized belt transect protocol and simplified belt transect protocol yielded only 0.25 and 0.4 species per hour respectively. The result of the study was further verified in three more habitats viz. natural forest, coffee plantation and tea plantation which gave similar results. The study indicates that the random search method which covers more area in less time yield more representative termite fauna in all the four habitats tested, than the standardized belt transect protocol which spends more time covering less area.
首先，在北喀拉拉邦沿海地区比较了三种白蚁采样方法，以检验广泛采用的标准化带样方案(Jones and Eggleton, 2000)与简化带样方案和随机搜索方法的效率。在共采集到的4属11种中，标准化带样方案在20小时的采样时间内仅记录到2属5种，而简化方案在10小时的采样时间内记录到2属4种。最小费力随机搜索法(6h)记录到4属11种，包含了之前方法收集到的所有物种。采样效率有显著差异;随机取样法每小时的采收率为1.87种，而标准化带样方案和简化带样方案的采收率分别为0.25种和0.4种。研究结果进一步验证了另外三种生境，即天然林，咖啡种植园和茶园，得到了类似的结果。研究表明，在所有4个被测生境中，随机搜索法比标准化带样法获得的代表性白蚁区系更多，随机搜索法的覆盖面积更小，随机搜索法的覆盖时间更长。

The study is to use AutoDock software to determine the binding affinity or binding energy of DEET, picaridin, prallethrin, and IR3535 components with the odorant receptor of the Anopheles gambiae say (Diptera, Culicidae) mosquito species. The binding energy (ÄG) of prallethrin was determined to be highest at -10.55 kcal/mol followed by picaridin at -7.1 kcal/mol, DEET at -6.57 kcal/mol and IR3535 at -5.6 kcal/mol being the lowest among all. By comparing their binding energy levels after AutoDocking, it is to decide which mosquito repellent is the most effective.

A review of the genus Macromia Rambur, 1842 (Odonata, Macromiidae) of Western Ghats of Peninsular India is presented with its updated distribution. An attempt is made to collate the scattered data in peer-reviewed literature published to date and is supplemented with field data gathered by the authors over two decades. Although Macromia is represented by nine species including six endemics in the Western Ghats, not much has been published on them from the region. Macromia irata Fraser, 1924 was described from Coorg but was rarely reported in peer-reviewed literature since its very brief original description by Fraser in 1924. The detailed morphology including that of the genitalia of M. irata is discussed. A revised classification based on the species groups and a key to the species of Macromia of the Western Ghats of Peninsular India is provided. To quantify the ratios of the number of the prenodal and postnodal veins in Odonata, a new nodal range expression called Standardised Species Nodal Range (SSNR) and a new index termed Standardised Species Nodal Index (SSNI) is also proposed.

A new species of cicada is described from south India. The new taxon, Purana cheeveeda Sadasivan sp. nov. is easily differentiated from all the other known species of the Purana tigrina species group based on its operculum apex not reaching beyond the anterior margin of sternite 3; tubercles on sternite 4 black and almost as large as those on sternite 3; relatively short rostral length reaching unction of abdominal sternite II and sternite III; the absence of dark fasciae on the transverse grooves of postclypeus, forewing venation, basal lobes of pygofer with large diverging triangular spines and the characteristic pentagonal uncus of the male. The status of Purana tigrina (Walker, 1850) from South India is discussed. The topotypes of the taxon commonly identified as P. tigrina from south India did not match the morphology of the holotype of P. tigrina. In addition, the study of the type specimen of P. tigrina demonstrated that the external morphology and male genital characters of the holotype of P. tigrina match that of P. tigrina from the Malayan region. Hence the type locality is mislabelled. This common taxon from southern India which has been traditionally misidentified is described here as a new species of Purana. As per Articles 76A.1.4 and 76A.2, of the International Code of Zoological Nomenclature (1999), the type locality of P. tigrina is hereby corrected as Malaysia. Based on the findings, P. tigrina is removed from the south Indian cicada fauna. The new species has some features common to both the Purana carmente group and Purana tigrina group, but most characters agree to Purana tigrina group, hence is tentatively placed in this group. The characters based on coloration may not be useful in species group classification in Purana, hence structural features like male genitalia and venation are taken to revise the existing species group keys. A modified key to the Purana species groups and members of the P. tigrina species group is also provided.
