Emergence rhythm and reproduction behavior of Hypsipyla robusta (Lepidoptera: Pyralidae)
The adult emergence and reproduction behavior of Hypsipyla robusta were studied at (25 ± 1) ℃ and 75％-80％ RH under 14L∶ 10D (light started at 06:00,ended 20:00).The results showed that the emergence rate of adult was 85.4％,and emergence period was 25 days; emergence behavior mainly happened in dark,the daily emergence peak occurred from 20:00 to 23:00,which counted 80.7％ of the total.The ratio of female to male was 0.83∶ 1.The adults became sexual maturity on the 2nd day after emergence.The adults did not mate on the 1st day after emergence.The mating peak occurred in 5 to 8 hours after entering seotophase.However,the mating duration increased from 50 min to 200 min.The mating frequency decreased with increase of adults age,but the duration of mating became longer.The adults began to oviposit on the 2nd day after mating.Both the female and mule mated orly once in their whole life.The oviposition of the mated female was 104 eggs on average and the egg stage lasted for 7 days,the ratio of egg fertility was about 84.3％.The unmated female spawned 157 eggs on average and the ratio of egg fertility was 0.On average the life span of mated female was 3.73 d,while the mated male was 2.93 d.Meanwhile,the life span of unmated female was 5.87 d,while the unmated male was 5.03 d.
