摘要
本文就蚕豆上潜蝇姬小蜂白昼活动规律进行了研究,在午间13:00-14:00时气温最高时,为潜蝇姬小蜂的活动高峰期,种群(Y)和温度(X)的白昼活动模式为 Y=-2.41+1. 38x- 0.09x2, r= 0.7221;在蚕豆成熟时,潜蝇姬小蜂种群数量最大。
The population fluctuation and activity of Diglyhus isaea were investigated in broad bean fields. Diglyhus isaea is most active. At noon 13: 00 - 14: 00, Its daytime activity in relation to population(Y) and temperature (X) could be described by the equation Y = - 2.41 + 1 .38x - 0. 09x2, r = 0. 7221 ,.
