研究证明昆虫病原线虫CZ—88(Steinernema sp.)侵染桃小食心虫的适宜温度为25~30℃,土壤含水量为10%~20%。线虫用量每666.7m~21亿条,1个月以内对桃小幼虫可保持很高的致死效果。线虫对常用农药及化肥等有较强的抗性。在苹果园利用此线虫防治桃小食心虫越冬出土幼虫优于常规农药。
The results showed that the optimum temperature for the infection of Steinernema sp. By Entomopathogen nematode CZ-88 was 25-30 ℃ and the soil water content was 10-20%. The amount of nematodes per 666.7m ~ 2.1 billion, within 1 month of peach larvae can maintain a high lethal effect. Nematodes on the common pesticides and fertilizers and other strong resistance. Use of this nematode in apple orchards to control peach moth overwintering larvae is superior to conventional pesticides.
