朱砂叶螨Tetranychus cinnabarinus寄主范围广泛,其对不同蔬菜寄主的取食选择性研究很少。本研究采用离体叶碟法和活体寄主法研究了朱砂叶螨在菜豆、茄子、番茄、黄瓜和甜椒等5种蔬菜寄主上的成螨数量、产卵数量、由卵发育至成若螨期的比例及活体寄主上叶螨数量的增长速度。结果表明,朱砂叶螨对供试的不同蔬菜寄主均可取食为害,但其对不同寄主存在取食偏好性。供试的5种寄主植物同时存在时,朱砂叶螨最喜食菜豆,在该寄主上种群发展速度最快,其次是茄子、番茄和黄瓜,在这3种寄主上的取食选择性差异不大,甜椒是该螨相对不喜食的寄主植物,但同样能够使叶螨成功完成其发育历期。离体试验和活体试验结果趋势一致。
Tetranychus cinnabarinus has a wide range of host hosts and few studies on the feeding selectivity of different host plants. In this study, the leaf moths and living host method were used to study the number of adult mites and the number of eggs laid on the spider mites, eggplants, tomatoes, cucumbers and bell peppers, The proportion of the period and the host growth rate of spider mite on the host. The results showed that Tetranychus cinnabarinus could feed on different vegetable hosts, but had preference for different hosts. When the five host plants tested were present at the same time, the most popular herbivore was Tetranychus cinnabarinus, and the population on the host developed the fastest, followed by eggplant, tomato and cucumber. The differences of feeding selectivity on these three hosts were not significant Large, sweet pepper is a relatively unaffected host plant for this mite, but it also enables spider mites to successfully complete their developmental history. In vitro and in vivo test results trend.
