The susceptibility experiment of two kinds of bio-pesticides to Adjoin variegata was evaluated using spraying apparatus in libarary.Imidacloprid 10% was contrast.The results showed that abamectin had higher toxicity,LC50 was 3.71807 mg/L,which was 3.96 times as much as contrast.The following was Matrine,LC50 was 4.18463 mg/L,which was 3.52 times as much as contrast.These indicated that it was susceptible bio-pesticides to Adjoin variegata and the toxicity of bio-pesticides was higher than imidacloprid.
