Abstract

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.

Abstract

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.

Abstract

Buprestid type collection has been studied and updated at National Forest Insect Collection (NFIC), Forest Research Institute (FRI), Dehradun, India. Buprestids in NFIC are represented by 11 subfamilies, 14 tribes, 15 genera having 54 holotypes 22 paratypes of 71 species. In the present contribution 71 insect specimens belonging to family Buprestidae their subfamilies, tribes with male and female of Holotypes and Paratypes are digitized alongwith coloured photograph of each specimen taken with automontage3-D imaging system for long term use.

Abstract

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.
