2010—2016年,通过羽化观察、成虫诱集、落果解剖等方法调查重庆市云阳县柑橘大实蝇发生情况。结果表明,该害虫羽化高峰期5月上旬,田间成虫活动盛期为6月中旬至7中旬,蛆果落地高峰期10月中旬至11月中旬,蛆果落地到幼虫开始入土间隔期2~8 d。大面积田间成虫诱杀适期为5月下旬至7月中旬,落果捡拾适期10月上旬至11月下旬。结合橘园蚧类等害虫防治,6月上旬至7月中旬可选用菊酯类农药防治柑橘大实蝇成虫。
From 2010 to 2016, the occurrence of citrus fruit fly in Yunyang County of Chongqing Municipality was investigated through feather observation, adult trap collection and fruit drop dissection. The results showed that the pest emergence peak in early May, field activity peaked from mid-June to mid-7, the maggots peak landing mid-October to mid-November, larvae larvae landed larvae landing interval of 2 to 8 d. Large areas of adult traps suitable for the field from late May to mid July, picking the appropriate period from early October to late November. In combination with pest control such as Orange Garden scale species, the pyrethroid pesticides can be used to prevent and control Citrus Daucus adults from early June to mid July.
