温度对中华锉叶蜂发育和存活的影响及药剂防治效果

Influence of temperature on development and survival of Pristiphora sinensis and control effect of some insecticides

中华锉叶蜂Pristiphora sinensis Wong是我国特有的害虫种类.在室内较系统地研究了温度对中华锉叶蜂发育和存活的影响,并进行了田间防治试验.结果表明,不同温度对中华锉叶蜂各虫态生长发育和存活具有明显不同的影响,在16,20,24,28℃条件下,卵、幼虫、蛹的存活率和发育历期均存在显著的差异,比较而言,以20～24℃较为适宜,温度过高或过低均有明显不利的影响.药剂防治试验表明,供试6种药剂处理对中华锉叶蜂幼虫均具有较好的防治效果.

Pristiphora sinensis Wang is one of peculiar insect pests in China and causes serious damage to plant leaves of Prunus persica （L.） Batsch. The influence of temperature on development and survival of P. sinensis by systematical breeding in indoor, and control experiment of some insecticides carried out in field. Results showed that there were of significantly different effects on eggs, larvae and pupae of P. sinensis under treatment of 16,20,24, 28℃ respectively. The temperature of 20 ～ 24℃ was more suitable than other any temperature treatment to its development and survival. Insecticide control experiments showed the tested insecticides were all of very good effects to larvae of P. sinensis before the insecticides were used in the 3rd instar larva.
