湿度对复苏后越冬玉米螟幼虫的影响

Effects of relative humidity on resuscitation larvae of Asian corn borer

在相对湿度２０％～１００％的环境中，越冬复苏后的亚洲玉米螟虫体重量均有所下降，不同湿度下虫体重量下降幅度差异明显。低湿条件下虫体重量下降幅度明显大于高湿，湿度在４０％以下时虫体重量下降趋于稳定。复苏后玉米螟死亡率与湿度呈负相关，２０％～４０％低湿条件下玉米螟不能化蛹，８０％～１００％高湿条件下能够化蛹，但最大化蛹率仅为４％和１０％。

All of resuscitation larvae of Asian corn borer were tested for their weight losses under 20%,40%,60%,80% and even 100% humidity,respectively The lower the environmental humidity was,the more the larval weight lost When environmental humidity was lowered below 40%, the decreased larval weighs approached to a stable situation Mortality of resuscitation larvae was negatively correlated to environmental humidity Furthermore,the resuscitation larvae were actually unable to pupate under low humidity With a very high humidity of 80%-100%,the pupation rate was about 10% only
