摘  要:
研究了4种以阿维菌素为有效成分的抗生素类杀虫剂爱诺虫清1号、爱诺虫清3号、减担子、饿死虫对稻田捕食性天敌八斑球腹蛛的致死力,结果表明:4种生物杀虫剂处理的八斑球腹蛛平均存活时间分别为9.69、7.74、3.59和3.72 d,均低于对照存活时间21.61 d;对照的死亡率与处理时间呈直线正相关,而各处理的死亡率经对数转换后与药后时间也呈直线正相关;处理间差异达到0.05水平显著。这说明阿维菌素对稻田捕食性天敌八斑球腹蛛具有一定的毒性。

摘  要:
In the paper the toxicity of four avermectin antibiotic insecticides to Theridion octomacutatum,the dominant species of spider in most rice-planting areas in China,was studied.The results showed that all the chosen avermectin antibiotic insecticides affected the survival of T.tomacutatum.When the test groups were sprayed with Ainuochongqing 1,Ainuochongqing 3,Jiandanzi and Esichong,respectively,they could averagely survive 9.69,7.74, 3.59 and 3.72 days,which were all shorter than that of the control group,21.61days.The mortality curve of the control group was positively correlated with the time,while those of the test groups were not positively correlated with time until the data were transformed logarithmically.The results of one-factor variance analysis showed that mortality rates among the groups were different from each other.It can be deduced that avermectin did an certain harm to the survival of T.tomacutatum.
