The study describes the identification of the spider assemblages with respect to their diversity within the Peechi-Vazhani wildlife sanctuary. A total of 106 species, from 24 families were recorded from the area,which forms baseline information of spiders of the sanctuary. Families showed varying degrees of habitat fidelity with some being abundant while others rare. Amongst these, Salticidae, Araneidae, Oxyopidae and Lycosidae were to have mor especies in the area. However, analyses of functional groups, e.g., ground runners (29%) showed the positive influence of structural complexity of the habitat.The presence of different species in all habitats highlights the importance of conserving a wide array of representative habitats within ecosystems.

To identify best mulberry variety for chawkie rearing and its impact on economic characters of silkworm (Bombyx mori L.), experiments were conducted in three seasons viz., autumn -2019, spring -2020 and autumn- 2020, with six mulberry varieties (C-2038, Tr-23, PPR-1(S-140), S-1635, S-146 and G-2). Based on the weight of 10 mature larvae (g), cocoon yield by weight (kg), single cocoon weight (g), single shell weight (g) and shell ratio (%), S-1635 and S-140 (PPR-1) were found suitable for chawki rearing in sub-tropical conditions.

Parapoynx diminutalis was observed in Hydrilla verticillata (a weed) in artificial tanks at Kerala Agricultural University. The incidence was so severe that the entire biomass of hydrilla was eaten away by the larvae which pupated in water. Pupal case was made of stem pieces of hydrilla, thus curtailing the growth and multiplication of the weed was suppressed in a period of one month indicating that this is a potential biocontrol agent for the weed.

The nesting sites of two species of stingless bees were located in Medziphema and Punglwa village which fall under the Dimapur and Peren districts of Nagaland. The nest of Lophotrigona canifrons Smith is subterranean in nature constructed inside cavities below ground and that of Tetragonula iridipennis Smith is arboreal in nature constructed on tree trunks inside cavities. The length and width of the entrance tube of T. irridipennis measured 26mm in length, 22mm in width and the total length of the tube including the accessed tube that connected with the nest measured 70mm. The area of the honey in T. irridipennis was 80x60x50mm, with 112g stored honey and 0.72g individual honey pot. In the case of L. canifrons length of the entrance tube was 20 mm and width 15 mm for the underground nest-1 (UG-1); and for the UG-II, the length and width measured 10mm and 14mm respectively. The honey pots of L. canifrons were dark brown to black in colour just like that of pollen pots. For UG-I, the honey area was 100x65x59mm; with 127g honey and 0.78g single honey pot. Similarly, in UG-II the honey area was 70x62x55mm with 114g honey and 0.80g of a single honey pot.

The persistence of cyantraniliprole, a new systemic insecticide of the class anthracitic diamide, was studied under the laboratory conditions in sandy loam soil and the soil amended with farmyard manure (0.5%), after spiking at 1, 2 and 4 ?g kg-1 levels in three different soil moisture regimes viz. air dry, field capacity level and also in saturated conditions. Degradation was comparatively faster in saturated than at field capacity and air dry condition. There was an increase in the persistence with increase in the spiking concentration. The persistence of cyantraniliprole was dependent on soil moisture condition, organic matter content and concentration of cyantraniliprole used.

Fourier transform infrared (FTIR) spectroscopic technique was carried out in wings of nine different Pierid butterflies to deduce the functional groups and properties of cuticular hydrocarbons which play a pivotal role in exhibiting charismatic colour patterns, controlling body temperature, attracting potential mates and camouflaging against predators. There were three major types of hydrocarbons present in all butterfly wings including alkanes, alkenes and methyl hydrocarbons. The second predominant compounds found in the butterfly wing region include alkyl halides, alcohols and phenols. There were no significant differences in the functional groups among the wings of butterflies. FTIR analysis of nine different Pierid butterfly wings showed many relative sizes of peaks. There were no significant differences in the chemical composition of wings but the colour differences were observed among the nine different butterflies. It was inferred that not majorly due to the differences in the cuticular hydrocarbons and may be due to the presence of different microstructures like scales, ridges and grooves.

Assessment of oviposition substrates and mating duration on the fecundity and egg hatchability of eri silkworm Samia ricini Donovan, revealed that maximum disease free layings were recorded in the control (353 eggs with 98 % hatchability) followed by the treatment, mating duration of six hours (332 eggs with 96 % hatchability). Poor egg laying and egg hatchability was noticed in one hour (151 eggs with 41 % hatchability). Correlation coefficients between mating duration, fecundity and egg hatchability showed strong positive correlation. Oviposition substrate’s impact on fecundity and egg hatchability revealed that gada cloth gave better results (344 eggs with 96% hatchability) whereas polythene cover recorded poor fecundity (203 eggs) and jack fruit kharika recorded poor hatchability (90 %). A minimum of six hours of mating duration is needed for the eri moth to attain its full fecundity potential and better egg hatchability.

Study undertaken to find the structural arrangement of scales in similar coloured regions within butterfly wings of different species revealed their scale structure was architecturally different. The scales under scanning electron microscope showed difference among butterflies. Scales of Papilio polymnestor (Cramer) had high concentration of windows, Pareronica ceylanica (Felder) with beads and other species such as Talicada nyseus (Guerin Meneville), Atraphaneura aristolochiae (Fabricius), Junonia heirta (Fabricius), Neptis hordonia (Moore), Acrae violae (Fabricius) and Danus chrysippus (Linnaeus) had network and lamina. Tonality of colours showed differences in the arrangement of scales.
