摘　　要：笔者以静电场为实验电场，以淡色库蚊（Ｃｕｌｅｘｐｉｐｉｅｎｓｐａｌｌｅｎｓ）的卵为处理对象，测定不同电场强度和处理时间对该蚊虫生物学特性的影响。研究结果提示：该蚊卵经静电场处理后，明显地改变了蚊虫胚后发育的各种特性；在１００ＫＶ／ｍ２固定场强下，９０ｍｉｎ处理后的幼虫存活率仅为０．５８．发育为成蚊后，其所产的卵块中约７０％左右的卵为未受精卵；在３０ｍｉｎ固定处理时间下，５０ＫＶ／ｍ２场强处理对蚊虫各项特性有利，而较高的场强则会起抑制作用；静电场的处理也明显增加了个体发育的差异。In this paper effects of the static electric field on the life system of Culex pipiens pallens were measured by treating its eggs with different expose duration and different electric field tensions.Results showed that the static electric field had an important influence on the post-blast development of the mosquito.In the electric field tension of 100KV/m2,the shorter the expose duration was.the less efficiency on the biological property of the mosquito the electric field had.The survival rate of larvae whose eggs were treated for 90 min.was only 0.58.In the expose duration of 30 min.,that of the electric field tension of 50KV/m2 was favourable to the development of the mosquito.but the higher electric field tension would repress its development.In the electric field tension of 250KV/m2, about half of the eggs laid by females was unfertilized. The electric field also affected the developmental rate of larvae.Finally,the reasons of the efficiency of static electric field was inferentially discussed.
