摘要
昆明地区蔬菜地拉美斑潜蝇幼虫危害和成虫活动主峰在4~5月,次高峰在10~11月。满天星花卉大棚内斑潜蝇种群主高峰在7~8月,次高峰在4~5月。蚕豆从11月到翌年4月,拉美斑潜蝇成虫数量呈上升趋势,幼虫在10~11月和2~4月为害较重。该虫在蔬菜地不转移危害,但在蔬菜与蚕豆地之间却转移危害。植株幼苗期和成苗期受害轻重依品种而异,植株中部叶片受害较重。
In an investigation of the population occurrence of Liriomyza huidobrensis and its damage to vegetables, floral plants and spring crops, two peaks occurred for its activity and damage to vegetables, one being in April and May and the other in October and November. Similarly, two peaks of the activity of Gypsophila paniculata occurred in plastic tunnels for floral plants, one in July and August and the other in April and May. In broad bean ( Vicia faba) fields, the number of adults of L. huidobresis increased progressively from October to April and its larvae caused great damage in October-November and in February-April. This pest did not cause transfer damage among vegetables, how ever its transfer damage was quite serious between vegetable fields and broad bean fields. The severity of damage it caused to young and adult plants differed with vegetable varieties, and the leaves in the middle parts of the plants suffered most.
