摘要
[目的]研究温度对稻水象甲飞行能力的影响,探索稻水象甲的迁飞规律,为控制稻水象甲的扩散提供依据.[方法]通过昆虫飞行磨系统测定不同温度下稻水象甲的飞行能力.[结果]在一定温度范围内,稻水象甲的飞行能力随温度的升高而增强,在温度为25℃附近时飞行能力达到最大值;随后,稻水象甲的飞行能力随温度的升高而下降.[结论]温度对稻水象甲的飞行能力影响较大,稻水象甲起飞温度为20℃,25～30℃是稻水象甲的最适飞行温度.在相同温度等条件下,稻水象甲越冬后成虫和入土前的飞行能力无明显差别.
[Objective] The flight capacity of the Rice Water Weevil：Lissorbqptrus oryzqphilus Kuschel （LOK） in different temperatures was surveyed,and the flight law of the LOK was explored in order to provide evidence for preventing LOK from dispersal.[Method] Systematic study was conducted about the LOK＇s flight capacity under the different temperatures by using the computer-monitored flight-mill.[Result] In a certain temperature range,the flight capacity of LOK increased with the rise of temperature,when the temperature was nearly 25℃,the flight capacity of the LOK was the strongest,and then,the flight capacity decreased with the rise of temperature.[Conclusion] Temperature had greater effect on flight capacity,the taking-off temperature of the LOK was 20℃,and the optimum flight temperature range was between 25℃ ～30℃.At the same temperature conditions,there was no obvious difference in the flying capacity between overwintering LOK and the LOK before going into the earth.
