1978年我们对稻纵卷叶螟的飞翔力(飞翔持续时间、振翅频率)及飞翔对卵巢发育的影响作了初步观察。为了进一步检验其结论,今年继续进行振翅频率观察,并改用电动节拍器计时,所得结果与去年十分近似(材料另报)。此外,今年还观察了飞翔前期(羽化幼期)、飞翔起始温度及起飞蛾龄。L.R.Taylor(1957)研究过豆蚜(Aphis fabae)羽化幼期的发育起点温度、有效积 In 1978, we conducted a preliminary observation on the flying force of C. medinalis (duration of flight, frequency of wing oscillation) and the effect of flying on ovary development. In order to further test its conclusion, this year continued vibration frequency observation, and use the electric metronome timing, the results are very similar with last year (material reported). In addition, this year also observed the early flight (emergence of young), the starting temperature of flight and takeoff moth age. L.R.Taylor (1957) studied the developmental onset temperature of the young feathering stage of Aphis fabae and the effective product
