Studies on the High Temperature Induced Stress on the Biochemical Profile and Fecundity of Daba and Laria Ecoraces of Tropical Tasar Silkworm Antheraea mylitta Drury (Lepidoptera: Saturniidae)

Biochemical Performance and Quantitative Assessment of F1 Hybrid of Two Ecoraces of Tropical Tasar Silkworm Antheraea Mylitta Drury (Lepidoptera: Saturniidae)

“…Higher concentration of the total protein and carbohydrates recorded in the present study for F1 hybrid is attributed to the fact that these larvae have acquired robustness due to the interecoracial crossing and fed higher quantity and quality leaves in turn efficiently converted the dietary food during its feeding stage, the corresponding level of proteins were maintained in the hemolymph, midgut and fat body. Also, many authors have similarly recorded higher proteins in the hemolymph of female earlier (Babu et al 2009;Kumar et al, 1998;Lokesh et al, 2012a;Kumar et al, 2011;Srivastava et al, 2001). The differential concentration recorded in different batches viz., Daba Laria and F1 hybrid depicts the differential feeding rate and physiological activity among different ecoraces and adaptively for the geographical region and food plant (Venugopala Pillai et al, 1987).…”

Host Plant Management Strategies for Quality Tasar Seed Cocoon Production

“…The nutritional quality of leaf influences the feeding behavior, growth and finally development of silkworm which later affect the cocoon quality and dfl production (Bhatia andYousuf, 2014 andRam et al, 2016). Prolonged rearing duration due to low nutritive value of foliage has serious implications like predatory pressure, population segregation and occurrence of pests and diseases (Bora andSaikia, 2022 andLokesh et al, 2016). The abnormal changes in the environment like scarcity of rains in some part contrary to heavy rains in the other part of country (erratic/unseasonal monsoon) had greatly contributed in increased predators and parasitoids activities like Xanthopimpla konowi (yellow fly), Blepharipa zebina (uzi fly) and predators like wasps, which mostly attack on silkworm during rearing and reduces the larval population leading to reduced cocoon yield (Rathore et al, 2018c andChandrashekharaiah et al, 2022).…”

Impact of High Temperature Gradients on the Physiolgical and Biomolecular Changes in the Tropical Tasar Silkworm Antheraea mylitta D

“…All biological processes including structure of proteins, biological membranes and rates of biochemical and physiological reactions affected due to high temperature stress [5,6]. The stress condition induces the changes in hemocytes of hemolymph and associated with physiological changes with release of higher rate of reactive oxygen species (ROS) in many insect species and particularly in silkworms [7][8][9] and hemocyte profile increases with an increased temperature and reduced hemocytes in the hemolymph when the silkworm exposed to lower temperatures [10][11][12]. The heat shock response is known to be evolutionarily and is a highly conserved biological response, exhibited by almost all living system [13,14].…”
