试验研究了苯达松、稻乐思、乙草胺、苄磺隆、神锄、金秋、艾割和果尔等除草剂对拟水狼蛛生长发育及捕食功能的影响。结果表明 :除金秋的抑制作用不明显外 ,其他几种除草剂对拟水狼蛛的抑制作用显著。对初孵狼蛛的直接杀伤力 ,果尔、稻乐思作用非常强 ,处理后 2 d狼蛛死亡率为 1 0 0 % ,乙草胺、苯达松分别为 60 %、4 0 % ,金秋、苄磺隆则无杀伤作用。多数除草剂处理 2 d后 ,拟水狼蛛捕食褐稻飞虱量有所增加 ;金秋处理 8d内 ,拟水狼蛛的捕食量显著高于对照 ,然后趋于正常。
The effects of bentazon, Inula, acetochlor, metsulfuron-methyl, kojic, golden autumn, elm and fruit herbicide on the growth and predation function of Pirata subpiraticus were studied. The results showed that except for the obvious inhibitory effect of autumn, the inhibitory effect of several other herbicides on the wolf spider was significant. The direct lethality to the newly hatched tarantula, Guer, Rao Si has a very strong effect. The death rate of the tarantula was 100% after two days of treatment, while that of acetochlor and bentazon was 60% and 40% respectively. Autumn, benzyl sulfon is no lethal effect. After 2 days of treatment with most herbicides, the amount of brown planthopper that had been ingested by Pirata subpiraticus increased, and within 8 days of autumn, the predation amount of Pirata subpiraticus was significantly higher than that of control and then became normal.
