稻虱螯蜂对水稻后期的飞虱为害有一定的控制作用,寄生率在10—30％。江苏稻田已经发现的稻虱螯蜂有5种:Haplogonatopus japonicus,H.atratus, Pseu-dogonatopus flvifemur,Echthrodelphax bicolor和P.fulgori.不同螯蜂对不同的飞虱有偏嗜性。不同品种稻田螯蜂的数量有明显差异。螯蜂的发生和飞虱的发生,以及水稻生育期有明显相关性。化学杀虫剂对螯蜂有很大的杀伤力。螯蜂的保护利用应从控制使用化学农药对稻飞虱的防治着手,共同发挥螯蜂与其他天敌在水稻综合防治中的控制作用。
The louse beetle on the late rice planthopper damage have a certain degree of control, the parasitism rate of 10-30%. Haplogonatopus japonicus, H.atratus, Pseu-dogonatopus flvifemur, Echthrodelphax bicolor, and P. fulgori have been found on rice paddy fields in Jiangsu Province. Different species of invertebrates are biased toward different planthoppers. The number of different species of rice bee had significant differences. Occurrence of bee-eaters and planthopper occurred, and the rice growth period has a clear correlation. Chemical insecticides have a lot of lethal effects on the bees. The prevention and control of rice planthoppers by controlling the use of chemical pesticides should be taken as the protection and utilization of the bee-bee and the mutual control of the behavior of the bee-eater and other natural enemies in the integrated control of rice.
