通过产卵驱避试验,筛选出对瓜实蝇具有良好产卵驱避作用的拟除虫菊酯类杀虫剂,结合植物表面膜剂和套袋技术,开展产卵驱避剂的田间应用技术研究,为瓜实蝇的产卵驱避技术应用提供科学依据。试验结果表明,在瓜果花期,喷施溴氰菊酯或氯氰菊酯25 mg/L和植物表面膜剂400倍液,并于谢花后3 d对果实进行套袋保护,可有效防治瓜实蝇为害,防治效果可达91.07%以上。 Through the spawning repellent test, the pyrethroid insecticides with repellent effect on oviposition of fruit flies were screened out, combined with the plant surface filming agent and bagging technology, the field application of egg repellent was studied , To provide a scientific basis for the application of spawning repellent techniques of fruit flies. The results showed that 25 mg / L of deltamethrin or cypermethrin and 400 times of plant surface filming agent were sprayed at fruit flowering stage and bagged at 3 days after cactus flower, which could effectively prevent and cure melon flies Damage, prevention and control of up to 91.07%.
