摘  要:
在实验条件下,测试了撞击力对丝棉木金星尺蛾幼虫假死行为的影响.结果表明:(1)幼虫出现坠地假死和吐丝假死两种假死现象,随撞击力增大,坠地假死、吐丝假死和总假死发生率均有增大的趋势.(2)吐丝长度、收丝时间和假死持续时间在不同撞击力之间差异不显著;各处理组吐丝长度与收丝时间均呈显著性正相关.结果可为利用假死行为防治丝棉木金星尺蛾提供理论依据.

摘  要:
Under the laboratory conditions, effects of applied force on death-feigning in Calospilos suspecta larvae were observed. These results showed:(1) Landing thanatosis and spinning thanatosis occurred in larvae. Frequency of landing thanatosis or spinning thanatosis, and the total frequency of thanatosis had increasing trend with the increase in applied force.(2) There was insignificant difference among different applied force treatments in silk length, collecting silk time, or thanatosis duration. The silk length had a significant positive correlation with the collecting silk time in all treatments. These results would provide fundamental theoretical basis for managing this pest.
