“…Further, the income from tasar silkworm rearing has perceived to be decreased, while mortality of final stage larvae of silkworm, frequency of pests and predators incidence, hatching problem in dfls during first crop have perceived to be increased by the majority of the tasar silkworm reares and they have received the rank of 4 Author's calculation conformity with the study of Zamal T. et al [41] and Chand and Kumar [42]. Sharma et al [43] in their study reported that a positive correlation was observed between temperature and diseases viz. grasserie (0.74) and flacherie (0.80) and high viral and bacterial infection was recorded in autumn season due to the high temperature and humidity.…”

Tasar sericulture is one of the allied sectors of agriculture which is a climate sensitive sector. Understanding farmer’s perception about the climate change impact on the rearing performance tasar silkworm is a key to the development of new climate tolerant technologies so as to encourage the other farmers for adopting sericulture eventually to boost the production of the tasar silk production in the state. Thus, the study was designed to establish farmer’s perception on climate change and its impacts on tasar silkworm rearing performance. The study was conducted in all four tasar silkworm rearing districts of Maharashtra namely Bhandara, Gondia, Gadchiroli and Chandrapur. A total 160 tasar silkworm rearers were selected randomly from all the four districts. Information was collected from each tasar silkworm rearers through Rapid Rural Appraisal (RRA) and focus group discussions (FGD). Climate Change Perception Index (CCPI) and Climate Change Impact Perception Index (CCIPI) were used to assess the perception about the impact of climate change on tasar silk production. Weighted Average Index (WAI) was used to analysis the impact. Results showed that majority of the respondents perceived that the yield and production of tasar cocoons production has reduced compared to last ten years. Moreover, frequent loss of the crop is noticed due to sudden change in the climatic conditions during the rearing of silkworm. Similarly, the high incidence of diseases and pest is also noticed thereby affecting the income generation of the tribal tasar farmers of the state. The results of the study will be useful for formulating appropriate policy against the ill-effects of the climate change. The results will also give impetus to the researcher to develop the thermo tolerant and climate change tolerant or resistant varieties or races of tasar silkworm so as to boost the tasar silk production of the state.

“…Effects of increased temperature on silkworm biology as well as yield can be incurred. A decrease in the yield of cocoon crops and sometimes failure of a crop due to disease has been noticed in B. mori due to global warming and abnormal rainfall patterns (Sharma et al 2020). A temperature rise shortens the immature development of B. mori (M2P2 variety) (Islam, 2018).…”

Lepidoptera is an order belonging to class Insecta consisting of Rhopalocera and Heterocera. B. mori belongs to this order and is the backbone of sericulture. Sericulture, the culture, rearing and maintenance of Bombyx mori (Linnaeus, 1785) for silk production, is widely practiced in India, contributing to its economy and providing livelihoods to many, especially those from lower socioeconomic backgrounds. Temperature and humidity affect silk production greatly. Heat shock genes and proteins protect B. mori to a certain extent from increased heat stress. However, outside this range, silkworm biology suffers. The silkworm adapts to heat by upregulating thermotolerance genes and proteins, especially heat shock proteins (HSPs). Produce different heat-resistant proteins at different temperatures. Larvae, embryos, and cocoons are affected by heat stress. Given the silkworm’s sensitivity to temperature and humidity and the alarming pace of climate change and global warming faced by the earth, it is necessary to consider solutions that will allow B. mori to adapt in the future decades. Molecular and enzymatic markers may help screen thermotolerant silkworm breeds. Given this insect’s temperature sensitivity, global warming and climate change may harm it even more than other insects. Therefore, to save this insect and the sericulture sector, steps must be taken in this direction.

“…The global mean temperature of the earth's surface has increased by about 0.74°C (IPCC (2007a). Due to global warming and abnormal rainfall patterns, there is continues failure of crop in autumn season (Sharma et al, 2020). Increase in temperature could well affect the sustained fresh water resources through accelerated melting of glaciers and snow in the high mountain areas (Hussain et al, 2005).…”
