摘  要:以槐木虱为研究对象,采用药膜法(FDA方法)测定了阿维菌素、单甲脒盐酸盐不同配比对槐木虱的室内联合毒力效果。结果表明:1:24、1:29阿维菌素与单甲脒盐酸盐混配表现出很强的增效作用,共毒系数(CTC)在144.6~1093.8之间;0.5:34.5、0.5:29.5、0.5:24.5阿维菌素与单甲脒盐酸盐混配72h共毒系数(CTC)分别为281.50、152.96、154.88,表明有增效作用,只有0.5:34.5阿维菌素与单甲脒盐酸盐混配在48h有增效作用,其它2个配比在24、48h共毒系数小于80,表现为拮抗作用;该试验结果表明,阿维菌素是生物农药,单甲脒盐酸盐是有机氮农药,两者合理混配是克服或延缓害虫抗性的有效措施之一。Taking Psylla willieti as research object,the velum contacting method (FDA method) was used to determine joint toxicity determination of different ratio of avermeetin to mono formamidine hydrochloride on Psylla willieti. The results showed that the mixed ratio of avermectin to mono formamidine hydrochloride had a strong synergistic action when the ratio were 1 - 24 and 1 : 29. The cotoxicity coefficient (CTC) was from 144. 6 - 1 093. 8. The cotoxicity coefficient of different ratio (avermectin-mono formamidine:0. 5: 34. 5,0. 5 : 29.5,0. 5 : 24. 5) was 281.50,152. 96,and 154.88 at 72 h respectively. The synergist action appeared on a ratio of 0. 5: 34. 5 (avermectin : mono formamidine) at 48 h. The antagonism effect was found in other ratios at 24 h and 48 h because cotoxicity coefficient was less than 80. The mix of biological pesticide (avermectin) and chemical pesticide (mono formamidine) was an efficient method which delayed resistance of pest population greatly.
