| 摘 要： | 增效磷(SV_1)对抗敌百虫家蝇有明显的增效作用,能够延缓家蝇对敌百虫抗性的发展.测定了敌百虫对一个敏感和两个抗性品系家蝇的表皮穿透作用,结果表明抗性品系家蝇对敌百虫的穿透速率比敏感品系低,说明表皮穿透作用的降低和体内解毒速率的增强在家蝇对敌百虫的抗性中起重要作用.SV_1与敌百虫混用后,穿透速率明显提高,敌百虫对家蝇表皮穿透速率的增强和体内代谢速度的降低是SV_1在抗性家蝇体内对敌百虫增效的机制之一.

| Abstract: | SV1 was observed to have obvious synergism and could delay housefly ( Musca domesticavicina ) resistance development to Dipterex. The penetration rates of Dipterex through housefly cuticle were determined in a susceptible and two resistant strains. The results indicated that the penetration in the resistant housefly strains was obviously slower than in the susceptible one. The penetrating rate of SV1 + Dipterex (in mixture) was higher than that of Dipterex. The penetration reduction in resistant houseflies may be an important factor in bringing forth resistance. The increase of the penetrating rate of Dipterex and the decrease of its metabolic rate are regarded as the important mechanisms of SV1 synergism to Dipterex. |
