Abstract:
To compare the control effect and determine the optimal concentration，five pesticides，20% Bete-cypermethrin，20% Aceta，10% Imidacloprid，2.0% Abamectin and 25% Fenproathrin were applied to Euphorbia pulcherrima to control greenhouse whitefly.The experiment was conducted in May 2010 in the Qinghai high-tech agricultural development company.The results showed that the best control effect was 800-fold dilution of 20% Bete-cypermethrin，the corrected control effect after 1，3，5 d was 73.87%，92.60%，74.95%，respectively；followed by 1 000-fold dilution of 20% Acetamiprid and the corrected control effect after 1，3，5 d was 62.47%，80.54%，67.48%.To avoid the greenhouse whitefly resistance，20% Acetamiprid could be used as a replacement of 20% Bete-cypermethrin.The control effect of diluted 25% Fenproathrin was above 40% and that of 3 000-fold dilution of 10% Imidacloprid was the lowest.
