摘要: The residual contact toxicity of three benzofuranoids (Z)-butylidenephthalide (1), (3S)-butylphthalide (2), and (Z)-ligustilide (3) identified in the rhizome Cnidium officinale (Apiaceae) to B- Q-biotype females Bemisia tabaci was evaluated using a leaf-dip bioassay. Results were compared with those eight conventional insecticides. Based on 24 h LC50 values, (254 ppm) (268 more toxic than (339 against B-biotype females, whereas (338 (586 females. Thiamethoxam, imidacloprid, acetamiprid differ significantly between (LC50, 1.7 11.6 vs 364.5 >3000 ppm). This original finding indicates that phthalides neonicotinoids do not share common mode action or elicit cross-resistance. Structure–activity relationship presen...
