Toxicity of plant extract mixtures on Lasioderma serricorne (Coleoptera: Anobiidae) with biomateriasls and material applications

摘要

The bioactivity of two plant extract mixtures on Lasioderma serricorne adults were investigated. As biomateriasls, the two plant extract mixtures had potent contact toxicity and fumigant toxicity against L. serricorne adults, which significantly increased with increasing treatment dosages. The toxicity of plant extract mixture II was stronger than that of plant extract mixture. For the contact toxicity, the LD50 values of plant extract mixture I and plant extract mixture II were 2.89 and 1.37 μL/cm~2, respectively. For the fumigant toxicity, the LD50 values of plant extract mixture I and plant extract mixture II were 284.42 and 82.95 μL/L air, respectively.
