| Abstract | ||||
| Commercial oils of Pimpinella anisum L., Eucalyptus globulus L., Funiculum vulgare L. and Cuminum cyminum L. plants were tested at the concentration of 2.5 % on the 4th instar larvae of Spodoptera littoralis. Feeding larvae on treated leaves with Pimpinella anisum and Eucalyptus globulus significantly reduced larval weight gained. There were no significant differences on fresh food consumption between all commercial oils tested and control; also between days and interaction between treatments and days. The results showed that all the tested commercial oils significantly reduced fresh weight of faeces. A 2.5 % concentration of Cuminum cyminum oil caused 50 % mortality, while the same concentration of Eucalyptus globulus oil caused 64.3 % malformation of the resulting pupae.All commercial oils treatments significantly reduced fecundity and fertility. Histobiological activity ofC. cyminum and / or E. globulus oil on the mid-gut of the treated larvae resulted in degreesof morphological abnormalities. | ||||
