摘　　要：对长壮蝎蝽(Laccotrephes robustusStal)成虫在水体内外的假死行为以及控制假死行为的关键部位进行了研究。结果表明:(1)水体外假死时长明显高于水体中;(2)对不同捕食压力的适应导致蝎蝽在水体内外假死行为的差别,并能够提高自身的适合度;(3)蝎蝽的假死行为并不完全受脑或某一神经节控制,胸部各体节均有独立完成假死动作的可能。The present study dealt with the death-feigning behavior （ thanatosis ） of adults of Laccotrephes robustus Stal under different active space, and the controlling area of main body parts. The resuits indicated that： （ 1 ） The thanatosis duration outside water was obviously longer than that in water; （2） the adaptation to the different predation pressure possibly resulted in the behavioral difference in or outside water, which increased the fitness of L. robustus ; （3） Thanatosis was not completely controlled by brain or one single ganglia, each segment of thorax may has ability to control death-feign.
