Abstract:: Taking Chinese wolfberry 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.
