不同温度对黑色软蚧蚜小蜂生长发育的影响
Effecf of Different Temperatures on Growth and Development of Coccophagus yoshidae
【摘要】 黑色软蚧蚜小蜂在 1 8～ 30℃的室内试验温度范围内 ,各发育阶段的历期随温度的升高而缩短 ,发育速率则随温度的升高而增大。全世代的发育起点温度和有效积温分别为 8.40℃和 45 6.0 9日度。
【Abstract】 Under the temperatures of 18～30 ℃ in Lab,the developmental period of the immature stages (egg to pupa) for Coccophagus yoshidae Nakayama shortened while the developmental velocity increased as the temperature increased.The initial development threshold temperature and effective accumulated temperature of whole generation were determined as 8.40 ℃ and 456.09 ℃,respectively.
