温度与释放高度对大草蛉和丽草蛉成虫扩散行为的影响
Effect of Temperature and Release Height on Dispersal Behavior of Chrysopa pallens (Rambur) and Chrysopa formosa Brauer Adults
摘要
Abstract
Many factors affect the dispersal behavior of adults of green lacewings Chrysopa pallens and Chrysopa formosa and finally determine the efficacy of these natural enemies. This research investigated effects of temperature and release height on dispersal behavior of C. pallens and C. formosa adults. In the range of 15℃ to 30 ℃, the lacewings dispersed further with increase in temperature, and gradually dispersed to the area near the ceiling of greenhouse and the upper part of plants. In 30 ℃, 96% of C. pallens and 95.% of C. Brauer adults distributed in this area. There were no significant differences in the diffusion distance between the two lacewing species at 20℃, 25℃and 30℃. But C. Brauer (1.8 m) dispersed significantly further than C. pallens (1.39 m) at 15℃. In another release at (27±2)℃and (70±10)%RH, when released at height between 60 cm and 180 cm, the lacewings moved obviously to the upper part of plants and the ceiling of greenhouse with increase in release height. When released at 180 cm, most lacewings (>90%) distributed in the upper region in the greenhouse, while less than 5%distributed in the area 60 cm below plant canopy. To improve the colonization ability of green lacewing adults, the release height should be at 120 cm or less.关键词
