人工饲料饲养稻纵卷叶螟的生长发育与繁殖
Growth and Reproduction of Cnaphalocrocis medialis Fed on Improved Artificial Diet
摘要
Abstract
The growth and reproduction of rice leaffolder, Cnaphalocrocis medialis, fed on an artificial diet were studied. The results showed that larvae were able to grow and pupate fed on the artificial dict. Durations of larva and pupa were 28. 1 d and 10. 1 d, respectively, 6.1 d and 1.7 d longer compared with that reared on rice leaves. Number of ovipositions were 41.6 per female, 26.2 percent higher than that fed on rice leaves. the survival rate of larva followed a descent mortality-age function,and was not significantly different from that of larva fed on rice leaves. The net reproductive rate, intrinsic rate of increase and finite rate increase of population were 17. 6928, 0.0884 and 1. 0942. The mean generation time and population doubling time were prolonged for 4.9 d and 1.3 d in comparison with those of larvae fed on rice leaves. The population trend index was 3. 26,indicating an ascent trend of the population of Cnaphalocrocis medialis fed on artificial diet.关键词
