摘要
本研究对吉林省中部地区露地十字花科蔬菜主要害虫的种类及其发生动态进行系统调查,调查结果表明,危害吉林省中部地区露地十字花科蔬菜的主要害虫共2纲6 目14科26种,其中鳞翅目害虫种类最多(57.69％),其他害虫依次为半翅目、鞘翅目、双翅目、缨翅目和蜱螨目.对春茬十字花科蔬菜危害严重的是小菜蛾、菜青虫和潜叶蝇;对秋茬十字花科蔬菜危害严重的是菜青虫和蚜虫,其中,小菜蛾发生高峰期在6月下旬至7月上旬,菜青虫与小菜蛾混合发生,发生高峰期在8月下旬到9月上旬,蚜虫在十字花科蔬菜生长中后期发生严重,9月中旬达到高峰.潜叶蝇在5月末发生量较大,进入6月后随温度升高种群数量快速降低.本研究全面地总结了吉林省中部地区露地十字花科蔬菜主要害虫的种类和发生动态,为吉林省十字花科蔬菜有害生物综合治理提供了理论依据.
Abstract
The main pests and occurrence dynamics of open field cruciferous vegetables in the central region of Jilin Province were systematically investigated.The results showed that a total of 2 classes,6 orders,14 families and 26 species of pests were investigated and identified in this area,and the species of Lepidoptera pests predominated in total,accounting for 57.69％,others were Hemiptera,Coleoptera,Diptera,Thysanoptera and Acari.The main pests seriously harmful to cruciferous vegetables in spring were Plutella xylostella,Pieris rapae and leaf miner,and the main pests in autumn were P.rapae and aphids.The occurrence peak of P.xylostella appeared from late June to early July.The P.rapa and P.xylostella occurred mixed,but the peak appeared in late August to early September.Aphids occurred seriously in the middle and late growth stages of cruciferous vegetable,and the peak reached in the middle of September.The number of leaf miner was large at the end of May,but decreased rapidly with the increase of temperature in June.The study provided a theoretical basis for the comprehensive management of cruciferous veg-etables pests in Jilin Province.
