在实验室条件下,亚非草蛉的平均发育历期为:卵期3.1天,幼虫8.9天,成虫寿命雌虫101.7天、雄虫61.8天,产卵前期8.4天。每雌虫平均产卵量400.3粒。最大产卵量746粒。产卵高峰期为羽化后的16—24天。亚非草蛉对湿度的适应范围较广,但幼虫的死亡率与湿度的关系大。 亚非草蛉幼虫一生捕食柑桔潜叶蛾幼虫数平均为149.1头,其日捕食量随龄期的增大而增加。温度对草蛉幼虫的捕食效应具有显著的影响,在35℃时达到最高的捕食效应,而在15℃以下和40℃以上,则受到明显的限制。湿度对草蛉捕食潜叶蛾幼虫的影响呈Iogistic曲线。草蛉对潜叶蛾幼虫密度的功能反应属HollingⅠ型反应。草蛉幼虫对其自身密度的功能反应可用Watt模型模拟。草蛉对潜叶蛾幼虫的捕食作用率随捕食者个体间的相互干扰作用的增加而下降,两者之间的关系随草蛉幼虫数的增加呈幂函数下降曲线。 田间观察及室内试验结果表明,亚非草蛉是柑桔潜叶蛾的一种重要的捕食性天敌。
Under laboratory conditions, the average developmental duration of A. subtilis was 3.1 days for eggs, 8.9 days for larvae, 101.7 days for adults, 61.8 days for males and 8.4 days for pre-oviposition. The average fecundity per female is 400.3 grains. Maximum fecundity 746 tablets. The spawning peak is 16-24 days after eclosion. Aphis gossypii has a wide range of adaptation to humidity, but larva mortality and humidity are large. The average number of larvae fed on A. mongolian larvae during their lifetime was 149.1, and their daily predation increased with age. Temperature had a significant effect on the predation effect of larvae of larvae, reaching the highest predation effect at 35 ° C, whereas those below 15 ° C and above 40 ° C were significantly limited. The effect of humidity on the predatory larvae of the larvae of the lawn moss showed a Iogistic curve. The function of grass moss on the density of leaf moth larvae is Holling type Ⅰ reaction. The response of the grass larva to its own density can be modeled using the Watt model. The predation rate of grass moths on the leaf moth larvae decreased with the mutual interference of the individual predators. The relationship between them decreased as a function of power as the number of larvae increased. Field observations and laboratory tests showed that A. niloticus was an important predator of citrus leafminer.
