For evolving an eco-friendy, non-toxic and practically feasible method of minimizing the populataion of the most serious Teak leaf skeletonizer E. machaeralis, four egg parasitoids viz. Trichogramma brsiliensis, T. chilonis, T. pretiosum and T. japonicum were tested in laboratory conditions. T. brasiliensis proved a better potential species to parasitise maximum number of eggs in labortory i.e. 58 to 61 per cent. Further evaluation of T. brasiliensis in field conditions for their least effective dose, proved that the optimum dose of the egg parasitoid T. brasiliensis is 1.25 lakhs wasps/ha to minimize the attack of teak leaf skeletnizer, E. machaeralis.- Vanya Silk: Multipronged Approach to Streamline the Indian Tasar Seed Sector

Economic viability of the tasar silkworm rearing rely on leaf quality and most vitally on timely supply of quality tasar seed called Dfls (Disease Free Layings) in suitable brushing schedule of the region. But there exists a short supply of 74.02 1akh Dfls (51.4%) against an estimated demand of 144 lakh Dfls, and this is the major constraint in utilizing the full potential of 111.60 lakh ha natural tasar flora of the country. Existing four tier and wired together seed multiplication system in India needs a multipronged redressal measures, especially at P1 level. Further, turning nonfunctional Pilot Projet Centres into operational and establishing their pragmatic linkages with private graineurs of the area, demarcation of a distinguished "Seed Cocoon Zone", involving operational women SHGs and working NGOs for generation of additional seed cocoons, creation of Para workers group/lead farmers, beefing up the backward and forward linkages by State sericulture mechanism to manage demand-supply and cost-realization process, incentive support to the tribals for biodiversity conservation, realization of carbon credits, large scale propagation of tasar eco-races on natural Sal flora, creating water harvesting system, inter cultivation of medicinal plants in economic tasar food plantation, HRD initiatives, clusterisation for systemic extension services, protection of natural tasar habitats, proliferation of tasar culture under National Mission for Green India under NAPCC etc., are some of the interventions, which are discussed in this communication to streamline the Indian or tropical tasar (Antheraea mylitta Durry) seed sector in India.Keywords

Egg parasitoids belonging to the genus Trichogramma are well known biological control agents, being utilised in applied biological control of insect pests, particularly against lepidopterous pests of agricultural crops and forest tree species. In the present paper, important diagnostic characters of all Indian species of Trichogramma have been given, in brief. Host-range of the Indian Trichogramma spp., along with their distributional record has also been up-dated. Scope of application of Trichogramma spp. for controlling the key insect pests has also been discussed.Keywords

Taxonomy of Trichogramma species is very important for their biological control program. Various researchers have proposed the taxonomic keys based on genitalia but there are other important characters that needs consideration and these have been largely ignored by taxonomists while proposing the taxonomic keys. In the present study, the emphasis is given on morphometry of some important characters including genitalia in Trichogramma achaeae Nagaraja and Nagarkatti. The average body length of both male and female were measured as 0.478 mm and 0.543 mm, respectively, it showed that females are longer than males. Important characters such as head length and width, hind wing length and width, also length of its marginal fringes were measured including setae on RS1, RS2, r-m veins and statistically analyzed for significant differences. Detailed morphometry of T. achaeae is described and discussed.Keywords

Present study on diversity of coccinellid beetles comprises a significant group of predatory beetles which are being utilized in biological control of insect pests from more than one hundred years ago throughout the world. An extensive survey and collection of coccinellid beetles was carried out by following the sweep net and handpicking method during a period of two years, June 2016 to May2018, in Uttarakhand, India. Collection of beetles was also made at different altitudes. All the collected beetles have been identified up to species level. In total, fifteen species of coccinellid beetles were identified as Aiolocaria hexaspilota (Hope), Anegleis cardoni (Weise), Brumoides suturalis (Fabricius), Coccinella septempunctata Linnaeus, C. transversalis Fabricius, Harmonia dimidiata (Fabricius), Henosepilachna vigintioctopunctata (Fabricius), Hippodamia variegata (Goeze), Illeis confusa Timberlake, Menochilus sexmaculatus (Fabricius), Micraspis allardi (Mulsant), Micraspis univittata (Hope), Oenopia sexareata (Mulsant), Platynaspidius saundersi (Crotch) and Propylea dissecta (Mulsant). H. vigintioctopunctata is phytophagous while I. confusa is mycophagous; all other species are predatory feeding on mealy bugs and aphids occurring on forest tree species. Out of all identified species, four species A. hexaspilota, I. confusa, O. sexareata and P. saundersi have been recorded for the first time from Uttarakhand.Keywords
