摘要:

为了明确短时高温暴露对Q型烟粉虱成虫存活及生殖适应性的影响,将Q型烟粉虱成虫在不同温度(37℃、39℃、41℃、43℃、45℃)下暴露1h后研究了成虫存活率、产卵量及F1代存活率的变化。结果表明,Q型烟粉虱在37~45℃范围内暴露1h后,成虫存活率由100%下降到21.4%,41℃及以上高温对Q型烟粉虱成虫存活率有显著影响;高温暴露后Q型烟粉虱成虫产卵量没有显著影响,Q型烟粉虱成虫在41℃及以上高温下暴露1h后F1代的存活率显著下降。

Abstract:

The effects of brief exposure to high temperature on survival and fecundity of Bemisia tabaci Q-biotype, (Homoptera: Aleyrodidae) were studied in the laborary condition.The survival rate, reproduction and survival rate from egg to adult of F1 progeny of B. tabaci Q-biotype were evaluated after the adults were exposed to five degrees of temperature, 37, 39, 41, 43 and 45℃, for 1 hour.The survival rates of adults of b B. tabaci Q-biotype decreased with the increase of temperature. Within the range of 37 to 45℃, the survival rate of B. tabaci B-Biotype adults decreased from 100% to 21.4%,. Adult survival was significantly affected when they were exposed at 41°C or higher temperature. Female oviposition was not significantly different when adults were heat-exposured at all temperatures. The percentages of F1 offspring developing to adults were significantly affected when temperature increased to 41°C.
