摘要

Insecticidal and acaricidal responses of Cinnamomum cassia oils made by organic solvent (OS), steam distillation (SD), and supercritical fluid (SF) and their components were examined in two bioassays (contact and fumigant bioassays) against Plodia interpunctella, Sitophilus oryzae, S. zeamais, Tyrophagus putrescentiae, and Sitotroga cerealella adults. Using the contact or fumigant bioassay against T. putrescentiae adults, OS oil exhibited the strongest toxicities (50% lethal dose [LD50], 2.60g/cm(2) and 1.34g/cm(3)), followed by SF and SD oils. Furthermore, using two bioassays, SD oil against S. oryzae and S. zeamais adults exhibited the strongest toxicities (LD50, 102.25g/cm(2) and 68.62g/cm(3), 102.03g/cm(2) and 57.59g/cm(3)), followed by SF and OS oils. Using the fumigant bioassay against S. cerealella and P. interpunctella adults, OS oil exhibited the strongest toxicities (LD50, 1.17g/cm(3) and 0.79g/cm(3)) followed by SF and SD oils. Cinnamaldehyde, cinnamyl acetate, and coumarin against T. putrescentiae adults showed no significant differences in the contact bioassay, but in the fumigant bioassay, cinnamaldehyde exhibited the highest toxicity (LD50, 0.91g/cm(3)) followed by cinnamyl acetate and coumarin. Against S. oryzae, S. zeamais, S. cerealella, and P. interpunctella adults, cinnamaldehyde using two bioassays exhibited the most potent toxicities (LD50, 108.81g/cm(2) and 77.80g/cm(3), 104.72g/cm(2) and 36.48g/cm(3), 0.57g/cm(2) and 2.29g/cm(3)), followed by coumarin and cinnamyl acetate in order. The results showed that cinnamaldehyde and the C. cassia oils could be effective values in the management of stored product pests.

Oryzae和S.Zeamais成年人表现出最强的毒性(LD50,102.25g / cm(2)和68.62g / cm(3),102.03g / cm(2)和57.59g / cm(3)),然后是SF和OS油。使用Fumigant Bioassay针对S. cerealella和p. interplyplyella成人,OS油表现出最强的毒性(LD50,1.17g / cm(3)和0.79g / cm(3)),然后是Sf和SD油。 Cinnamaldehyde,醋酸糖醛和香豆素对抗T.Putclestiae成人显示出没有显着的差异,但在熏蒸剂生物测定中,肉桂醛表现出最高的毒性(LD50,0.91g / cm(3)),然后是糖糖和香豆素。针对S. ORYZAE,S.Zeamais,S. CEREALLELA和P. interpclyleta成人,使用两种生物测定的肉桂醛表现出最有效的毒性(LD50,108.81g / cm(2)和77.80g / cm(3),104.72g / Cm(2)和36.48g / cm(3),0.57g / cm(2)和2.29g / cm(3)),然后是香豆素和醋酸糖。结果表明,肉桂醛和C. Cassia油可能是有效的储存产品害虫的价值。
