The host plant selection behaviour or feeding preferences of the insects are largely mediated by the presence and distribution of secondary metabolites in plants. Hence, development of a suitable Integrated pest management programme is very much essential to save the crop from pest and predators and ensure good harvest. Though Tripura is endowed with well demarcated sub-tropical and temperate zones with a low average temperature of 10°C in the winter season which rises to a maximum average of 35°C in the summer, it supports the cultivation of tropical Tasar silkworm in a very unique manner naturally. Thus this species is phylogenetically less adaptive reaching its ecological isolation that is indicative of being on verse of extinction. 2010; 4(1). Effect of different food plants on the Fatty alcohols or -TQ alone do not induce beetle feeding significantly, but a mixture of alcohols and -TQ synergistically stimulates beetle feeding. Healthy egg production is indeed the primary requisite for conducive growth of the entire silk industry. 3. Noal Farm Recommended for you. Accounting to the State Sericulture Department, the State has produced 114.56 MT Muga Raw Silk, during the year 2011-12 as against 113.28 MT Muga Raw â¦ Due to the fact that many industrially developed countries where Biotechnology is reaping its fruits unfortunately do not practice sericulture, this has resulted in non-attempting of biotechnological approaches in sericulture. Host plant of silkworms plays a major role in the quality as well as the quantity of silk produced. 3.27(ii)]. A well established mulberry plantation of KNG (Japanese) for chawki rearing and Goshoerami (Japanese) for late age rearing with uniform growth and vigour were used for the study.

Extension Services Need to Be Modulated and Implemented. Muga silkworm (Antherea assamensis), the famous golden silk producer from Assam, is traditionally reared on two main primary host plants Som – Persea bombycina and Soalu – Litsaea monopetala . Further, the, Sericulture is an industry that is characterized by a two-step process, the cultivation of mulberry trees and the rearing of silkworms on mulberry leaves to produce cocoons. Host plants of Muga silkworm. Silkworms depend on their host plant for food source. The present study was undertaken to assess the performance of autumn crop (August-September) over spring (May-June) in temperate region of Jammu and Kashmir by rearing the silkworm hybrid (CSR 2 ×CSR 4) in both spring and autumn seasons 2016. Since non-mulberry silkworms are polyphagous in nature, thus on the basis of host plant preference the host plants can be classified as primary, secondary and tertiary. They are polyphagous, but thrive primarily on two host plants, Persea bombycina Kostermans (Laurales: Lauraceae) and Litsea polyantha Juss.
