以组建生命表的方法研究了糠片蚧在28℃恒温下的生死过程,为糠片蚧的防治提供了理论依据。结果表明,糠片蚧在28℃恒温下,净生殖率为10.75,内禀增长率为0.26,周限增长率为0.295/周,世代平均周期等于9.18周。用化学农药防治幼蚧或雌成蚧,若防治效果分别达到71.4％和13.5％时,即可控制糠片蚧数量增长。化学农药乐斯本、杀扑磷防治雌成蚧效果较好;氧化乐果、氰戊菊酯分别与机油乳剂混合施用可大大增强杀虫效果。
The method of constructing the life table was used to study the birth and death process of bran scale at 28 ℃, which provided a theoretical basis for the prevention and control of bran scale. The results showed that the net reproductive rate was 10.75, the intrinsic rate of increase was 0.26, the rate of growth per week was 0.295 / week and the average generation period was 9.18 weeks at 28 ℃. The use of chemical pesticides to control young scale or female scale, if the control effect reached 71.4% and 13.5% respectively, you can control the amount of bran scale. The chemical pesticides, such as Lebanon and Ketofos, have a good effect on the prevention and treatment of female melatonin. The combination of omethoate and fenvalerate with the oil emulsion can greatly enhance the insecticidal effect.
