摘要
2008年在上海市研究了番茄和黄瓜的种植密度对烟粉虱Bemisia tabaci(Gennadius)种群动态的影响和化学防治方法。结果表明,烟粉虱的种群数量在寄主的生育期内持续增长。在不同密度条件下,在发生高峰期,番茄和黄瓜上烟粉虱成虫及4龄若虫数量比较为:低密度>正常密度>高密度。在药效试验中2.2%甲氨基阿维菌素苯甲酸盐微乳剂3000倍和10%烯啶虫胺水剂2000倍的处理,对防治烟粉虱成虫具有较好的效果。
Effects of host plants density on the population dynamics of Bemisia tabaci （Gennadius） and its chemical control were studied in 2008 in Shanghai. The results indicated that during growing stage of potato and cucumbe plants, the population of Bemisia tabaci increased continually. The differences between the population density of adult and 4^th instar nymphs during the peak of Bemisia tabaci on various planting densities on both potato and cucumber were significant, and the order was low-density 〉 normal density 〉 high-density. The pesticide of Emamectin benzoate and Nitenpyram could effectively control the pest.
