我省种植的节瓜,常遭受节瓜蓟马(Thripspaimi Karny)又名棕榈蓟马为害,特别是夏秋植节瓜受害更为严重,造成品质和产量严重下降。过去推广使用的拟除虫菊酯类农药兴棉宝、灭百可等由于长期单一使用、滥用或超浓度使用,造成防效逐步下降。为了解决节瓜蓟马的防治问题,1987年我们与广州市蔬菜办公室及其下属有关单位协作,继续在广州石牌、白云区石井镇和芳村区东漖镇等进行药效试验及大面积示范,结果证明沙蚕毒系的杀虫双、巴丹、杀虫单防治效果较好,节瓜增产显著。1987年仅广州白云区大面积示范使用杀虫双防治节瓜蓟马面积达5000亩次,1988年广州近郊
The cucurbits grown in our province are often damaged by Thripspaimi Karny, aka Thrips palmi, and especially the summer and fall plantains are harmed more severely, resulting in a serious decline in quality and yield.
