| dc.description.abstract | Biology of Rhene indicus and Cheitacamhium sp. was studied under laboratory conditions. The different life stages were reared using caterpillars of Opisina arenosella as prey. /?. indicus males required a mean of 83 (range 67—104) days after hatching to maturity, reached adulthood after six moults and lived for an average of 51.25 (range 25—77) days. Females required a mean of 79.5 (range 59—105) days after hatching to maturity, reached adulthood after six moults and lived for an average of 139.83 (range 71—296) days. Females were found to oviposit 6—31 days after mating, produced 7—10 broods and the number of spiderlings emerged from single egg mass varied from 9—37. The spider started feeding on ea-rly instar caterpillars of Opisina from the second instar onwards and the prey consumption ranged from 2—207 caterpillars. Males of Cheiracanthium sp. required a mean of 214.6 (range 162—261) days after hatching to maturity, reached adulthood after 12 moults, and lived for an average of 74.5 (range 35—122) days as adult. Females required a mean of 207 (range 169—248) days after hatching to maturity, reached adulthood after 12 moults and lived for an average of 85.7 (range 51—127) days as adult. Females oviposited in 8—30 days after mating, produced one to four broods and the number of spiderlings emerged from single egg mass varied from 9—86 with an average of 49.1. Except the first instar all the eleven instar spiderlings consumed Opisina caterpillars and the rate of feeding was observed to vary from 2—151 | en_US |
