Silkworm Bombyx Mori

In the present study, susceptibility of the mulberry pest G. pyloalis to the pathogens of silkworm, Bombyx mori was ascertained. The survey was carried out at the three locations viz. Mulberry farms of College of Temperate Sericulture, Mirgund and two mulberry farms of Sericulture Development Department, J&K located at Mirgund and Tulsibagh, Srinagar. The plantation is ravaged by different pests and diseases and as many as 11 major and 10 minor insect pests have been reported from Jammu and Kashmir (Sharma and Tara, 1985; Khan et al., 2004). Under temperate conditions, G. pyloalis (Walker) causes severe damage to mulberry crop and is considered as a major pest of mulberry in Jammu and Kashmir (Fotadar et al., 1998). Zeya et al. (2003) reported 20-25 percent damage to mulberry foliage in Kashmir is due to G. Pyloalis during July to October. The survey study showed high infestation of G. Pyloalis during the month of October, 2017 and 2018. The maximum infestation of 73.03% was observed at SDD Tulsi Bagh followed by 45.20% at SDD Mirgund and 32.99% at CoTS Farm. During the study various stages of G. Pyloalis were found infected with the Microsporidian and Nuclear Polyhedral Virus whereas Fungal and bacterial pathogens were not observed during the present study. The mean incidence of Microsporidian and NPV was observed as 4.22% and 5.99% percent respectively during October, 2017. In the present study, susceptibility of the mulberry pest G. Pyloalis to the pathogens of silkworm, Bombyx mori was ascertained so that management strategies are taken accordingly

One of the major reasons of low productivity in chilli is the lack of technical knowledge of the farmers about judicious and timely implementation of the management strategies against the major biotic stresses (insect pests and diseases) which ultimately reduce its return. Considering the integrated crop management on need based plant protection in vegetables was conducted in farmer’s fields at different villages of the Kalaburagi district, under northern part of Karnataka, during the period from 2011-12 to 2013-14 show the productivity potential and profitability of improved technologies. The results showed that, on an average the highest yield achieved by adopting integrated crop management was 260.17 quintals ha-1, whereas the corresponding yield ranged under farmer’s practices was to 235.243 quintals ha-1 of green chillies. Adoption of integrated crop management will increase the yield 10.56% over farmer practices. The average technological gap, extension gap and technological index were noticed 139.83 quintals ha-1, 24.92 quintals ha-1 and 34.95 % respectively. The economics of data indicated that an average of Rs. 1,64,500 ha-1 was recorded net profit under recommended practices while it was Rs 129976.7 ha-1 under farmer practices. Cost benefit ratio was 3.07 under demonstration, while it was 2.35 under farmer practices. Practicing of integrated crop management with improved technologies will improve the farmer socio-economical level.

Datura stramonium L. (Solanaceae) is an annual weed found in most temperate and subtropical regions of the world. It has been recorded from all the provinces of Canada except Newfoundland, but is most common in Ontario and Quebec. It occurs in waste places, gardens, barnyards and, increasingly, in cultivated fields. Datura stramonium serves as an alternate host for many insect pests and diseases of Solanaceous crops, such as tomatoes, tobacco and potatoes, and has both narcotic and medicinal properties due to its production of a variety of alkaloids. It has been used extensively as an experimental plant in studies of genetics, chromosome morphology and embryonic development.Key words: Weed biology, jimsonweed, Datura stramonium, distribution

Aim: To determine the species composition and status pests of stored sorghum under traditional storages of farmers in Kenna district of Konso Zone of Southern Ethiopia. Study Design: From peasant association, about three sub-localities were randomly selected and from each sub-locality, three villages were selected at random with using a nested design. Place and Duration of Study: Survey was conducted between 1, August to 27, December 2019 in four major sorghum growing peasant association of Kenna district of Southern Ethiopia. Methodology: The study on determination of the species composition and status pests of stored sorghum was made from of half kilogram of wheat grain sample taken from 720 stores of randomly selected representative farmer’s storages of four peasant associations using key of books related to stored product insects. Results: Fifteen arthropods species consisting of twelve primary and secondary pests and three natural enemies belonging to four insect orders with in nine families were recorded. Of which, nine species such as S. zeamais, S. oryzae, S. cerealella, T. castaneum, T. confusum, C. ferrugineus,    C. pusillus, R. dominica and P. interpunctella, respectively were found to be the most abundant as they appeared between 3.47 and 19.44 individuals per 100 g of sampled grains. They were also found to be the most frequently occurring as they occurred in the range between 63.89 and 94.44% per 100 g of sample grain collected from survey site and had major pest status. Conclusion: The traditional methods and practices used by farmers were inefficient for providing adequate protection of their stored sorghum grain pests. Therefore, there is urgent need for designing effective management strategies against insect pest’s sorghum as well as improving the existing farmer’s traditional storage strictures in the survey site in order to reduce the loss of stored sorghum by insect pests and the associated food insecurity.

Chemical Pesticides

Crop protection against pests and diseases is of prime importance and plays a major role in agricultural production both in the Developed and Developing parts of the world.Although chemical pesticides have been in use for a long time it is only since the Second World War that a very heavy and almost exclusive reliance has been placed upon their use. This, in many cases, has resulted in the rapid build-up of resistance by insect pests to such compounds, as is illustrated by the rapidly developed resistance to the organochloride insecticides by the cotton bollworm, Heliothis virescens. Indeed, there are many examples of resistance in a major pest being observed within the first year of field use (Metcalf 1986). In some cases the indiscriminate application of pesticides has exacerbated the problem of insect herbivory where elimination of a wide range of predatory species along with the primary pests has resulted in secondary pests becoming primary pests themselves with even more devastating effects (Heinrichs & Mochida 1983).

Adequate Food

Ever-growing population, climatic changes and unprecedented losses due to pests and diseases pose serious threat to food security. Precisely food security implies availability of adequate food to everyone in all times to come. Food and Agriculture Organization of united Nations (FAO) defines “food security” as a state of affairs where all people at all times have access to safe and nutritious food to maintain healthy and active life. Food is one of the three basic needs of man, without which his survival is at stake. Plants constitute the basic source of food and as such, plant health management is crucial to food security, which is jeopardized due to unprecedented threat by large number of insect-pests, diseases, weeds and several edaphic and environmental stresses. Srivastava (2008, 2009) has very well highlighted the importance of plant heath security through phytomedicines/pesticides and plant health clinic in order to prevent 40 per cent losses occurring from field to fork globally. Due to unabated rise in population, reduction in arable land will be an ongoing process, hence we may have to strive hard to grow more food from limited land employing innovative strategies and more importantly adopting multipronged initiative and timely diagnostic and management strategies from plant health clinic to combat attack from pests and environmental stress, manage plant health mitigate losses.

Genetic diversity is critical to success in any crop breeding and it provides information about the quantum of genetic divergence and serves a platform for specific breeding objectives. It is one of the three forms of biodiversity recognized by the World Conservation Union (IUCN) as deserving conservation. Silkworm Bombyx mori, an economically important insect, reported to be domesticated over 5000 years ago by human to meet his requirements. Genetic diversity is a particular concern because greater genetic uniformity in silkworm can increase vulnerability to pests and diseases. Hence, maintenance of genetic diversity is a fundamental component in long-term management strategies for genetic improvement of silkworm which is cultivated by millions of people around the worlds for its lusture silk. In this paper genetic diversity studies carried out in silkworm using divergent methods (quantitative traits and biochemical and molecular markers) and present level of diversity and factors responsible for loss of diversity are discussed.
