Abstract
Life history study of short-tail or giant cricket (Brachytrupes portentosus) was conducted under laboratory condition with controlled temperature about 24.68+-1.26 deg C. Aquarium boxes filled about half way with sandy soil were used as rearing cages. The giant crickets were feed mainly by many kinds of weeds and plant leaves, which were found naturally in their holes. Besides fruit, bread, and dried fish powder were added as supplementary feeding diet. Water was kept in a small plastic container and sprayed on the leaves as drinking water and to keep the soil moisture. The study revealed that after hatching the giant cricket has a total of seven instars with a whole life cycle 333.30 +- 20.06 days. One female gives an average 123.00 +- 46.44 eggs. The incubation period of eggs was 56.10 +- 15.03 days, the percentage of egg hatching was about 40.70 +- 4.74 percent while the whole growth period including seven instars of nymph and adult was 173.70 +- 19.86 days. The male cricket has brown rough wings and its size is slightly larger than the female. The female has smooth wings with patterns and visible ovipositor. The life cycle of the male was 86.50 +- 12.02 days shorter than the female, 109.70 +- 25.32 days. The growing stage of the female took 87.67 +- 14.74 days before laying eggs and 22.33 +- 9.50 days after laying eggs. In the rearing cage condition the survival rate was 25 percent for the whole population. Sex ratio of male : female was 1:1.5 respectively.
