Reports a subterranean termite species Microcerotermes lahorensis Akhtar from Kerala, India, for the first time. The species was only reported from the type locality Lahore, Pakistan, and was endemic to the country. This new record thus changes the endemic status of the species and reaffirms the cosmotropical nature of the genus Microcerotermes.

Onomarchus uninotatus (Orthoptera, Tettigoniidae), one of the neotropical Pseudophyllinae is recorded on the jackfruit (Artocarpus heterophyllus) var. Vietnam Super Early at Thrissur, Kerala, India. This is a new distributional report of the species from Kerala and additional new documentation as a serious pest of jackfruit from India. The nymphs and adults are nocturnal in habit and feed on the leaves resulting in withering and drying of the leaves giving a burned up appearance to the canopy. The species exhibited colour polyphenism with green and brown morphs in the nymphal stages. A detailed description of the nature of damage caused by the pest is given.

For determination of morphological and biochemical basis of resistance in cowpea against the pod borers (Maruca vitrata F. and Helicoverpa armigera Hübner), ten cowpea cultivars were evaluated during kharif 2017 and 2018. Results revealed that cultivars having indeterminate growth, yellow flower, light green and short pods as well as long peduncle recorded lower pod borer population. Correlation between different plant morphological characters and the larval population were found non-significant. The cultivars having low protein, high phenol and low total soluble sugars in flowers and immature pods recorded lower the larval population. The correlation between biochemical components of flowers and larval population were found to be non-significant. Biochemical components of immature pods revealed that phenol exhibited significant negative relationship with larval population, whereas, correlation of total soluble sugars of immature pods exhibited significant positive association with larval population. Among the cultivars screened, GC-6 and GC-1605 were found to be consistently resistant based on different morphological and biochemical factors and pod borer infestation. Relatively GC-1609, GC-1611 and GC-2 showed lesser pod borer infestation. GC-1606 was found to be highly susceptible.
为了确定豇豆对荚果螟虫(Maruca vitrata F.)和棉铃虫(Helicoverpa armigera h bner)抗性的形态和生化基础，在2017年和2018年对10个豇豆品种进行了抗性评价。结果表明，生长不确定、花黄、豆荚短、花梗长、淡绿色的品种豆荚螟数量较低。不同植物形态性状与幼虫种群的相关性不显著。低蛋白质、高酚和低总可溶性糖的品种的花和未成熟豆荚的幼虫数量较少。花的生化成分与幼虫数量的相关性不显著。未熟豆荚中酚含量与幼虫数量呈显著负相关，而总可溶性糖含量与幼虫数量呈显著正相关。在筛选的品种中，GC-6和GC-1605在不同形态和生化因素及螟虫侵染情况下具有一致的抗性。相对而言，GC-1609、GC-1611和GC-2的螟患较少。GC-1606被发现是高度敏感的。

Rice yellow stem borer (YSB), Scirpophaga incertulas Walker is one of the major destructive insect pests rendering huge crop damage. Nine insecticide formulations, either solely or in combinations were applied in the rice (var. Lalat) field for two consecutive seasons during 2019-2021 to assess their efficacy to suppress YSB population and to stabilize yield. The combination of flubendiamide (480 SC) @80 g a.s.ha-1 on 45 DAT and deltamethrin (1%) + triazophos (35%) @300 g a.i.ha-1 on 80 DAT, treated the rice crop, recorded minimum YSB incidence (4.14 egg clutches, 4.78 larvae and adults 3.17/5 hills) and damage (2.12% dead hearts (DH) and 1.47 white ear (WE). This treatment gave significantly higher grain yield (3.63 t ha-1), an increase of 45.78 per cent over control. The incidence (12.21 egg clutches, 14.12 larvae and adults 11.76/5 hills) and crop damage (14.83 DH and 11.10% WE) was maximum in the treatment, neem seed kernel extract (5%) @50 ml L-1 at 15 day intervals after transplanting and neem leaf extract (5%) @7 ml a.s. L-1 on 35, 50, 65 and 80 DAT, resulting in minimum yield (2.88 t ha-1). Other combinations of insecticide application gave variable results.
水稻黄茎螟虫(Scirpophaga incertulas Walker)是严重危害水稻的主要害虫之一。2019-2021年连续两季在拉拉特水稻(var. Lalat)田间单独或联合施用9种杀虫剂配方，以评估其抑制YSB种群和稳定产量的效果。氟虫胺(480 SC) + 80 g a.a.a.ha -1 (45 DAT) +溴氰菊酯(1%)+三唑磷(35%)+ 300 g a.i.ha-1 (80 DAT)组合处理水稻，YSB发生率最低(4.14个卵窝，4.78个幼虫和成虫3.17/5)，危害最小(2.12%死心(DH)和1.47个白穗(WE))。该处理显著提高了籽粒产量(3.63 t hm -1)，比对照提高了45.78%。在移栽后15 d，印楝籽仁提取物(5%)每隔50 ml L-1，印楝叶提取物(5%)每隔35、50、65和80 d，印楝叶提取物每隔7 ml a-1，产量最低(2.88 t ha-1)，发生率(12.21个卵窝，14.12个幼虫和11.76/5山)和作物危害(14.83 DH和11.10% WE)最高。其他杀虫剂组合施用的结果不尽相同。

Altitudinal variation and role of leaf nutrients in the host plants of tasar silkworm Anthraea mylitta Drury (Lepidoptera, Saturniidae) influences, the rearing, grainage and quantitative traits of tasar and in the quality of cocoon formed. The present works analysed the nutritional status of the tasar host plant leaves of asan (Terminalia tomentosa) and arjun (T. arjuna) collected from Kendujuani (508 m ASL), Mudrajodi (223 m ASL) and Kuliana (64 m ASL) in the district of Mayurbhanj, in Similipal Biosphre Reserve, Odisha. The study revealed that, nutritional value of asan leaves is better at a higher altitude (Kendujuani). The concentration of ascorbic acid in the leaves of asan and arjun was found higher in the leaves from Kendujuani.

Antifeedant activity of methanol and hexane extracts of aerial and root extract of Sphagneticola trilobata (L) pruski was tested against seven day old larvae of Spodoptera litura (Fab.) (Lepidoptera, Noctuidae) by no choice method of bioassay. A maximum antifeedant activity of 52.96 per cent was recorded at 0.1 per cent of methanol extract of aerial parts after 24 h of feeding. Root extracts exhibited low level of antifeedant activity against S. litura. At lower concentrations of 0.005, 0.01 and 0.03 per cent, there was no significant antifeedant activity. Antifeedant activity recorded after 48 h of feeding was similar to 24 h experiment but a slight reduction was noticed for 0.1 per cent of the methanol extract.

Investigation showed that Aedes albopictus (Skuse, 1894) of Chidambaram-Town, Annamalai-Nagar and Muthiah-Nagar of Tamil Nadu are still susceptible to the insecticide organophosphorus temephos with 98–100 mortality percentages. The resistance ratios of all the three sentinel sites are negligible. LC50 value was 0.002 - 0.003 ppm with high significance. It was the first temephos bioassay case study conducted on DENV vector Ae. albopictus in the selected sentinel sites and estimated lethal concentrations.
