摘要
目的 :了解抗药性对蜚蠊药激驱出效果的影响 ,研究其解决对策 ,探讨抗性蜚蠊种群、密度调查方法。方法 :药膜接触法 ,蜚蠊药激驱出 (Flushing out)试验及模拟现场试验。结果 :在实验室按 53ml/m3喷药 ,0 .3%氯菊酯、0 .0 5%溴氰菊酯、0 .1%高效氯氰菊酯、0 .3%苯氰菊酯、1.0 %DDVP对德国小蠊敏感品系的半数驱出中时 (FT50 )分别为 2 .2 4、1.2 6、1.85、3.2 5、6 .81min ,对菊酯抗性品系 (对溴氰菊酯的抗性系数为 18.13)的FT50 除DDVP为 34.0 6min外 ,均大于 12 0min ;1.0 %氯菊酯、0 .5%溴氰菊酯对抗性品系的FT50 也均大于 12 0min ;0 .3%氯菊酯 +1.0 %DDVP对菊酯抗性品系的FT50 为 14.2 0min。模拟现场按 50ml/m2 喷药 ,0 .3%氯菊酯对德国小蠊敏感品系的FT50 为 5.14min ,对菊酯抗性品系的FT50 大于 12 0min ;0 .3%氯菊酯 +1.0 %DDVP对菊酯抗性品系的FT50 为 2 4 .4 4min。结论 :拟除虫菊酯对菊酯抗性品系蜚蠊的药激驱出效果明显减弱 ,传统使用的 0 .3%氯菊酯酊剂药激检查 ,对菊酯已产生抗性的蜚蠊密度准确性不高 ,建议与DDVP复配进行药激或使用粘蟑法、目测法进行调查。
This research reported that deltamethrin resistant strain of the German cockroach were tested for flushing out effect by insecticides by the time flushing out response method in comparison with a known susceptible strain in laboratory and analogue field. The values of FT 50 of cockroach, which resistant ratio was 18.13 to deltamethrin, sprayed by 0.3 % permethrin, 0.05 % deltamethrin, 0.1 % high effect cypermethrin, 0.3 % cyphenothrin, and 1.0 % DDVP alcohol solution were more than 120min, unless by DDVP was 34.06min, comparing with 2.24 , 1.26 , 1.85 , 3.25 , 6.81 min respectively for the susceptible strains at the dose of 53ml/m 3. The FT 50 of resistant strain were 14.2 min treated by 0.3 % permethrin+ 1.0 % DDVP and more than 120min sprayed by 1.0 % permethrin and 0.5 % deltamethrin respectively. The FT 50 of resistant strain were 24.44 min treated by 0.3 % permethrin+ 1.0 % DDVP and more than 120min sprayed by 0.3 % permethrin comparing with 5.14 min for the susceptible strains tested in the analogue field at the dose of 50ml/m 2. The result indicated that the effect of flushing out was obviously weak for pyrethroid to resistant strain. It was suggested that the cockroach investigation was carried out by 0.3 % permethrin with 1.0 % DDVP treatment or by stick method.
