| 摘 要： | 采用田间罩笼和盆栽试验的方法研究了葱蝇成虫对4种寄主植物的产卵选择，采用室内培养的方法研究了幼虫对寄主植物的取食选择。结果表明：在4种寄主植物中，田间罩笼试验以洋葱上葱蝇的发生数量最多，其次为大蒜和大葱，韭菜上数量最少|盆栽试验中，葱蝇成虫对4种寄主植物的产卵选择与田间罩笼试验结果一致，均以在洋葱上落卵量最多，韭菜上落卵量最少|葱蝇1龄和3龄幼虫对寄主植物的取食选择，均以选择洋葱的幼虫最多，大葱的次之，韭菜和大蒜上的较少。表明葱蝇成虫的产卵选择是决定葱蝇幼虫在不同寄主植物上发生程度差异的重要因素，诱杀成虫是葱蝇防治的重要措施之一。

| Abstract: | Explored the onion fly(Delia antique(Meigen))adult oviposition selection in field cage and pot experiments and larval feeding preferences through indoor experiments.The results showed that the highest onion fly population occurred in onion,and the next population was in garlic and scallion,the lowest occurred in leeks through field cage experiments.The results of oviposition preference in pot experiments indicated the same trend as the field cage experiments.The lay eggs reached the most amount at onion,the lowest at leeks.The most favorite plant of the 1st larvae was onion,the next was scallion and the least were garlic and leek.The 3rd instars larvae showed the same preference as the 1st larvae.In a word,the most favorite host plant of onion fly was onion,the next was scallion and garlic,the least was leek.Moreover,we found that the oviposition selection of onion fly was the important factor in its population occurrence.So trapping and killing adult flies have applicable value in controlling onion maggot. |
