摘要： Field trials were conducted to determine the potential use of thiacloprid for integrated Meloidogyne incognita and Bemisia tabaci B biotype control in cucumber (Cucumis sativus Linn.) in China. The following five treatments were evaluated: three thiacloprid doses (7.5, 15, and 30 kg ha(-1)), an avermectin treatment (7.5 L ha(-1)) and an untreated control. All thiacloprid application rates were effective for reducing the M. incognita and B. tabaci B biotype populations. M. incognita was reduced by 51.0%similar to 86.7% on 60th day and B. tabaci B biotype was reduced by about 37.2%similar to 95.3% within 21 days, respectively. In addition, greater thiacloprid doses resulted in fewer nematodes and whiteflies. Over two successive years, the cucumber plants that were treated with thiacloprid at a dose of 15 kg ha(-1) had the greatest plant height, plant vigor and marketable yield, which were 134.1 cm, 91, 1514.3 g plant(-1), respectively in 2010-2011 and 151.9 cm, 93, 1651.4 g plant(-1), respectively in 2011-2012. In addition, thiacloprid was superior to avermectin. The results of this study demonstrated that thiacloprid could be used in cucumber production for the integrated control of M. incognita and B. tabaci B biotype. Furthermore, a dose of 15 kg ha(-1) of thiacloprid was recommended for controlling nematode and whitefly populations according to the control effect and marketable cucumber yield.
