针对黄曲条跳甲在蔬菜上,特别是在十字花科蔬菜上发生危害严重,难于防治的问题,笔者进行了黄板+信息素组合技术诱捕黄曲跳甲成虫和采用昆虫病原线虫“奈马”等防治黄曲跳甲幼虫的试验,结果显示:在菜心、小白菜和上海青3种十字花科蔬菜上,信息素+黄板组合技术7d平均每板诱捕黄曲条跳甲成虫数为91~384头,比同棚对照黄板诱捕黄曲条跳甲的数量增加44.44~124.56%,差异极为显著;采用昆虫病原线虫“奈马”制剂和昆虫病原线虫新品系制剂100倍液,灌根处理盆栽试验的结果表明,处理后6d两种病原线虫制剂寄生黄曲跳甲幼虫的平均死亡率依次为80.95%和100%。可见,采用信息素+黄板组合技术诱捕黄曲条跳甲成虫,与昆虫病原线虫“奈马”等制剂液灌根处理杀灭黄曲条跳甲幼虫相结合的非药剂防控技术,能够有效控制危害严重的黄曲条跳甲。
In order to deal with the problem that yellow beetle beetles are on vegetables, especially in cruciferous vegetables, the author has carried out the technology of combining yellow plate + pheromone trapping technology to trap yellow beetle adults and adopt the insect pathogen nematode “ The results showed that on the three kinds of cruciferous vegetables such as Brassica campestris, Chinese cabbage and Shanghai green, the podin + The number of adult adults was 91-384, which was 44.44- 124.56% more than that of the yellow-leaf-trapped yellow beetles, which was significantly different from that of the control. The nematode and nematode new strains The results showed that the average mortality rate of Parasitoida paraquat larvae of two pathogenic nematodes preparations were 80.95% and 100% after 6 days of treatment, respectively. Visible, using pheromone + yellow board combination of trapping the beetle imago, adult and insecticidal pathogenic nematode ”Nepalese " and other liquid preparation to kill the yellow striped beetle larvae combined non-drug control technology , Can effectively control the serious damage of yellow strip beetle.
