藜芦碱对枸杞蚜虫室内活性测定及安全性评价

Laboratory Activity Determination and Safety Evaluation on Veratridine Preparations to Chinese Wolfberry Aphids

以枸杞蚜虫为研究对象,采用浸虫法测定藜芦碱对枸杞蚜虫(成虫、若虫)的室内毒力,采用药害评价法测定藜芦碱对枸杞树生长发育的使用安全性。结果表明:供试药剂0.5%黎芦碱SLX与1%黎芦碱TKL对枸杞成蚜的毒力相当,0.5%黎芦碱SLX对枸杞若蚜的毒力略高于1%黎芦碱TKL,枸杞若蚜对藜芦碱的敏感性高于枸杞成蚜。黎芦碱制剂对枸杞树的叶片、花、果实均无药害产生,田间使用安全。

Taking Chinese wolf berry aphid as the object,the toxicity of veratridine to Chinese wolfberry aphids was tested in the laboratory by dipping methods,the safety of veratridine to wolfberry^s growth and development was evaluated by the ADR evaluation method. The results showed that,the virulence of veratridine 0. 5% SLX and veratridine 1% TKL to Chinese wolfberry adult aphid were correspond. The virulence of veratridine 0. 5% SLX to Chinese wolfberry nymph aphid was slightly more than veratridine 1% TKL. The sensitivity of Chinese wolfberry nymph aphid to veratridine was higher than that of Chinese wolfberry adult aphid. Veratridine preparation on leaves, flowers and fruit of wolfberry had no phytotoxicity and was used safely in field.
