Objective To study the effects of southernwood leaves,eucalyptus leaves and mangrove avicennia marina leaves ethanol extracts on the insecticidal activity and chitinase inhibitory activity against Galleria mellonella.Methods The insecticidal activity and chitinase inhibitory activity of the three plant ethanol extracts were tested for indoor contact toxicity by using sprinkling method. Results The results showed that after 24 h treatment,the corrected death ratios of southernwood ,eucalyptus and mangrove avicennia marina leaves ethanol extract were (69.00±3.87)%,(53.47±11.63) %,(18.60±6.70) % and the inhibition ratios of chitinase were(20.33±1.42)%,(20.59±1.72)%,(13.56±1.58)%, respectively.Conclusion The insecticidal activity and chitinase inhibitory activity of southernwood and eucalyptus leaves ethanol extract were higher than mangrove avicennia marina leaves ethanol extract markedly.
