葱斑潜蝇年发生 6～ 7代 ,以蛹越冬。 4月中下旬越冬蛹开始羽化 ,4月下旬见幼虫 ,5月中旬出现第 1代成虫 ,以后各代重叠发生 ,盛发期在 6～ 9月份 ,完成 1代需 1 7～ 31天。研究明确了该虫的生物学习性 ,虫态历期及温湿度对其生存发育的影响 ,应用综合防治技术取得了良好的防治效果和显著的经济效益。 Green onion leafminers occur in 6 to 7 generations, overwinter with pupae. The overwintering pupae begin to emerge in mid and late April. The larvae are seen in late April, and the first generation of adults appear in mid-May. Afterwards, all generations overlap, and the peak period is from June to September. The study identified the biological behavior of the insect, insect state duration and temperature and humidity on the impact of its survival and development, application of integrated control technology has achieved good control effect and significant economic benefits.
