7种化学药剂对枸杞蚜虫的室内毒力

Toxicity Determination of Seven Chemicals on Wolfberry Aphis in the Laboratory

测定7种化学药剂对枸杞蚜虫的室内毒力。结果表明,供试的7种杀虫剂中,48 h后高效氯氟氰菊酯原粉、溴氰菊酯原粉、联苯菊酯原粉毒杀效果最好,毒死蜱原粉、醚菊酯原粉、吡虫啉原粉、啶虫脒原粉毒杀效果次之。24 h后的毒力结果与48 h后的毒力结果基本相同。建议在生产上采用高效氯氟氰菊酯、溴氰菊酯、联苯菊酯防治枸杞蚜虫。

The toxicity of seven chemical pesticides to wolfberry（Lycium barbarum） Aphis was determined under laboratory conditions.Insecticidal toxicity of the seven pesticides after forty-eight hours ordered from highest to lowest as follows：High-efficient lambda-cyhalothrin,Deltamethrin,Bifenthrin,Chlorpyrifos,Ethofenprox,Imidacloprid,and Acetamiprid.However,the toxicity was almost the same between after twenty-four hours and after forty-eight hours.High-efficient lambda-cyhalothrin,Deltamethrin and Bifenthrin were higher toxic than others and could be recommended for use in wolfberry production.
