环境胁迫对亚洲玉米螟及其主要寄生性天敌的影响

Effect of Environmental Stress on Asian Corn Borer and Its Natural Parasitoids

亚洲玉米螟是我国粮食主产区玉米等作物上的主要害虫。综述了气候等环境因子对玉米螟及其主要寄生性天敌的胁迫作用。过高及过低的温、湿度对玉米螟的生长发育等均有不同程度的影响,同时还间接影响玉米螟寄生性天敌的存活和寄生效率;水分和食料对玉米螟幼虫生长发育、幼虫滞育和滞育解除等也有重要影响。总之,异常环境条件会极大地影响玉米螟及其寄生性天敌的种群消长。

This paper summarizes the effect of climate factors to Asian corn borer and its natural enemies. The combination of temperature and humidity mainly affect the fecundity, egg production and longevity of the adult. Its combination also indirectly influences the mortality and the parasitizm rate of its natural enemies. Water makes an important role in the mortality and diapause termination of over-wintered larvae. In a word, climate factors are closely related to the population increase or decrease of Asian corn borer and its natural enemies.
