野外环境下影响拉脊蝠蛾产卵量的相关性研究

昆虫野外交配行为与地理环境、气象因素等有关系。通过3年观测蝠蛾野外的羽化情况和交配行为,分析气象因素和地理环境对蝠蛾的羽化、交配和产卵的影响及对产卵量的相关性,结果表明:蝠蛾孵化时间为每日的17:00点左右,气象因素为有微风、阳光充足,地理环境为缓坡多灌丛地带时,随着拉脊蝠蛾的羽化数量和质量的提高、成虫交配数量的增加,产卵量明显上升。通过多元回归方程分析,在人工干预下提高交配数量可以进一步提高产卵量。

Study on the correlation between the influences of wild environment and eggs amount of Hepialus Guidella

The mating behavior of insects in the wild is related to geographical environment and meteorological factors. This paper analyses the effects of factors of environment and atmosphere on moth's eclosion, mating and spawn by observed the behavior of Hepialus Guidella's eclosion and mating at the field station within 3 years. The results showed that the time of eclosion was about 17:00 per day, the weather was breeze, sunny, the environment is gentle slope with more brush, the amount of eggs of Hepialus Guidella increased with the increasing of quality and quantity of moth's eclosion and adult mating. The mating quantity can be improved under human intervention, while increase can further improve the amount of eggs .
