The evaluation of silk worm lines for seed cocoon production was studied in humidity stress conditions during spring 2009. The selected silk worm lines viz. Pak-1, Pak-2, Pak-4, PFI-1, M-103, M-107 were reared at 25 plus minus 1 degree C in combination with different relative humidity (RH) levels i.e., 80 plus minus 5% (control), 50%, 60%, 70% and 90% RH. The maximum fecundity (number of eggs laid by a single moth) was observed at 80% RH (436) followed by 70% RH (320), 60% RH (305) and 90% RH (218). The highest hatchability was observed at RH of 80% (88.66) followed by 90% (71.05), 50% (70.28) and 60% (60.10). The best pupation occurred at 80% RH (88.44) followed by at RH of 70% (81.44), 60% (73.16) and 50% (68.94). T
