麦红吸浆虫在不同滞育温度和时间条件下羽化率的初步研究
Preliminary Study on Emergence Rate of Sitodiplosis mosellana under Different Temperature and Time
摘要
Abstract
In order to explore the optimal diapause time and temperature of Sitodiplosis mosellana , its diapause and emergence was studied indoors simulating field temperature. Results showed that for the first diapause,Sitodiplosis mosellana could achieve emergence under 4 ℃ ,6 ℃ ,8 ℃, 9 ℃ ,10 ℃ ,11 ℃ for 60 days,75 days,90 days,105 days,120 days,respectively. The highest emergence rate of 31. 67% occurred under 4 °C for 75 days. For the secondary diapause, Sitodiplosis mosellana could not achieve emergence under some temperature conditions and the highest emergence rate was 8. 00% under 8 ℃ for 120 days. The highest emergence rate was 33. 50% under 4 ℃ for 75 days after two cumulative diapauses. The remaining live cocoon rate was relatively low after two emergences, with the highest rate of 4. 00%. The mortality rates of diapause cocoons and larvae were all more than 60%,up to 96. 17%.关键词
