AbstractAspects of mating behaviour such as male readiness for mating, female receptivity, male courtship behaviour, mating and post mating behaviour of female have been studied in Gryllodes sigillatus. Male is ready for mating at 72 hours after adult emergence. Female is receptive at 36 hours after adult emergence. The forewings and antennae of male play a significant role in producing the ‘chirping’ sound to attract the female and in recognising the opposite sex by contact chemoreception, respectively. In addition, male releases a bubble like, transparent and gelatinous material, the mating jelly prior to mating. Mating lasts for about 3 to 4 minutes during which the spermatophore along with mating jelly is transferred to the genital aperture of the female. Soon after mating, the female removes the mating jelly and retains in its mouth for chewing. The spermatophore is retained in the genital aperture for sperm release. After about 29 minutes, the empty spermatophore is either discarded or eaten up by the female.
