应用生命表方法 ,组建了病毒类生物农药和化学农药对斜纹夜蛾田间种群控制作用的生命表。结果表明 ,病毒类生物农药对斜纹夜蛾种群有明显的控制作用 ,预测斜纹夜蛾下代种群数量降至当代的 0 .2 0 3倍 ;化学防治区的下代种群数量上升至当代的 1.884倍。
The life table method was used to establish the life table of the control action of biological pesticides and chemical pesticides on the population of Spodoptera litura. The results showed that the virus biopesticide significantly inhibited the population of Spodoptera litura and predicted that the population of Proximals of Spodoptera litura reduced to 0.203 times of the present age. The population of the next generation in the chemical control area increased to 1.884 Times
