高温冲击对东亚小花蝽存活及生殖特性的影响
Effects of High Temperature Shock on Survival and Reproductive Characteristics of Orius sauteri
摘要
Abstract
The survival rate, pre - oviposition period, oviposition amount and longevity of O. sauteri adults were determined after shocked for one hour under different high temperatures (39, 41,43℃ ). The resuits showed that- with the increase of temperature, the survival rate of O. sauteri adults decreased from 94. 44％ to 68.89％. The pre - oviposition period of female O. sauteri was prolonged significantly. The average pre - oviposition period was 2. 56 days at 25℃, while that was 4. 11 days at 41℃ after shocked for one hour. The oviposition amount per female decreased significantly by the high temperature shock for short time,which was averagely 60. 44 at 25℃, but decreased to 24. 10 at 41℃ and 13. 78 at 43℃ after shocked for one hour. The adult longevity decreased with the increase of temperature. It was averagely 15.33 days at 25℃,but dropped to 8. 11 days at 43℃. These results indicated that high temperature shock for short time decreased the reproductive adaptability of Orius sauteri.关键词
