摘要
本文报道了稻纵卷叶螟成虫的性比、寿命.产卵.潜在生殖力以及不同温度对其产卵的影响;不同的世代成虫性比不同,其变化范围为1:0.8—1.3;成虫的寿命平均为4.7天;雌成虫一般产卵2—3次,总产卵量为101.38±38.153粒/雌;但其潜在生殖力达223 8粒/雌。根据实验结果,组建了以温度为自变量的产卵模型.
The experiments on sex ratio, longevity, oviposition and reproductive potential of rice leaf—roller were made and the influence of different temperatures on the oviposition was discussed.It is shown that the sex ratio in different generations is 1 : 0.8—1.3; the average longevity of adult is 4.7 days; number of egg production is 101.38±38.153/female and the reproductive potential is 223.8/female.Based on the results of experiment, a simulation model of oviposition with temperature variable was deve oped.
