为了解樱桃果蝇的生物学特性和高效防治药剂,2010年对引入的樱桃果蝇进行了室内饲养观察和防治的药效试验.结果表明,樱桃果蝇对选用的8种水果均有嗜食性,并可继代生殖；雌成虫产卵在樱桃果实表皮下,卵孵化后的幼虫蛀食果实造成危害；温度在(18士2)℃、(23±2)℃时,卵期2.4～3.0d,1.2～1.8d;幼虫期11.2～12.2d,5.6～6.5d；蛹期9.5～10.6d,5.0～6.2d；完成一个世代周期要23.1～25.4d,12.8～14.2d.1％甲氨基阿维菌素苯甲酸盐乳油3000倍液、90％敌百虫晶体1000倍液、40％辛硫磷乳油1 500倍液和25％噻嗪酮可湿性粉剂2000倍液药效较好,药后1h死亡率为85.00％～100.00％；3h为96.67％～100.00％;6h为100.00％.
Biological Character Observation and Insecticide Screening of Drosophila melanogaster on Cherry
A test of pesticide effectiveness was conducted in 2010 to know the biochemical characteristics of D. Melanogaster and high efficient insecticides. The results showed that D. Melanogaster had preference to the eight kinds of fruits with proliferation. Female adult D. Melanogaster laid eggs under the fruit surface and they did harm to the fruits after incubation. Under the temperatures of (18+2)℃ and (23±2)℃: egg stage 2. 4~3. 0 d, 1. 2～1. 8 d; larval stage 11. 2~ 12.2 d, 5.6~6. 5 d;papal stage 9. 5~10. 6 d,5. 0~6. 2 d;one generation 23. 1~25. 4 d,12. 8~14. 2 d. Four insecticides(including 1% emamectin benzoate EC of 3 000 times, 90% trichlorfon of 1 000 times, 40% phoxim EC of 1 500 times and 25% buprofezin WP of 2 000 times) had higher pesticide effects on D. Melanogaster with mortalities of 85. 00% ~ 100. 00%, 96. 67% ~ 100% and 100% after sprayed for 1 h, 3 h and 6 h respectively.
