Tasar silkworm (Antheraea mylitta Drury) rearing and cocoon production are mainlycarried out by Tribal people of Central India and some parts of Odisha and Telangana states. Lack of Tasar silkworm seed production and preservationtechnology is creating difficulties in timely supply of adequate quantity of seed to the farmers and others stake holdersHigh temperature above 28ºC and less relative humidity than 50% are not suitable for the oviposition and hatching of eggs. In Tasar silk moth, egg retention was also more even after 72 h of oviposition in natural the present investigation, while providing optimum temperature (27-28ºC) and humidity (75-80%) in the egg laying room, egg laying was carried out in bivoltine and trivoltine broods under different stress conditions. The results indicated that in bivoltines (per5 moths), in T1 where antenna and wings were amputated, the number of eggs recorded were 1306, in T2 (legs and wings cut) it were 902 and in T3 (antenna, wings & legs cut), the number of laid eggs were 1154 when compared to 907 in Normal conditions (T0) for 5 months. | Studies on egg laying behaviuor and fecundity under different stress conditions in tropical Tasar silk moth
