Indian Silk has published several articles on white fly, a polyphagous sucking insect pest hitherto common in many agricultural and horticultural crops, has found place on mulberry and fast attaining the status of menace in South India. In the present article, the authors dwell upon a new variety of white fly, D. decempuncta which is causing great loss to mulberry in Kerala and Karnataka.

The pest infestation not only reduces the production of mulberry leaf, but also affects quality of leaf and in turn that of cocoons. In order to minimize the chemical inputs and save environmental hazards, a number of eco-friendly control strategies have been evolved. However, for the adoption of any technology, it is foremost important that awareness and knowledge about the same is essential. Hence, a study was taken up in Shapur cluster (Kolar district) comprising of 15 villages so as to know the knowledge and perception of insect pests and their management practices. The results revealed that all most all the farmers were aware of uzi fly and pink mealybug and the damage caused by the same. Majority of the farmers had the knowledge of leaf roller, Bihar hairy caterpillar and grass hopper. With regard to knowledge of IPM, all the farmers were aware of IPM ofwz/fly, but IPM of mulberry pests was known to very few of them. With respect to using bio-control agent against uzi fly, majority of them expressed non-availability as the major constraint and expected them to supply the same to their door steps at free of cost whenever needed.

The pattern of growth and the instability in sericulture in Kamataka has been attempted in the present study. Sericulture in Kamataka was at its prime during the National Sericulture Project Period. However, there was a significant fall in the area and production, which is explained through the negative and significant rate of Compound Growth Rate (CGR). The estimates of instability indices of area under mulberry and production of silk cocoon was quite low and nearer to zero both during and after the NSP periods. The instability during both the periods remained at very lower rate of standard deviation, nearing zero. This suggests that adoption of new technologies in sericulture marked the decline in instability. The dynamics in the direction of changing pattern in the area under different crops in Kamataka over a period was analyzed by employing the Markov Chain model. The transitional probability matrix showed that the crops such as maize, oil seeds, mulberry and other minor crops had stable acreage during the period.

Development of sericultural technologies and dissemination of the same played a major role in increasing the income and employment in the rural area. Efforts of various R&D organizations involved in sericulture have been responsible for the improvement of productivity in sericulture. It is to be noted that, various dimensions of technologies are test verified by the farmers before adoption at the field level. In this regard a field study was conducted to ascertain the awareness, attitude and the level of adoption of sericulture technologies. The results revealed that various extension variables effectively discriminated the respondents in to low. adopter and high adopter categories of technologies in sericulture. The variables such as average price per kg of cocoon, attitude towards new technologies in sericulture, awareness about the technologies and experience in sericulture emerged as the strong determinants for classification between 'bivotine silkworm rearers' and 'cross breed silkworm rearers'. Farmers with essential skills and awareness about the technologies were found to be highly motivated to take the necessary risk in production by way of higher rate of investment in sericulture.
