EAG Responses of Adult <i>Lobesia botrana</i> Males and Females Collected from <i>Vitis vinifera</i> and <i>Daphne gnidium</i> to Larval Host-Plant Volatiles and Sex Pheromone
We analysed electroantennogram (EAG) responses of male and female adults of the European grapevine moth <i>Lobesia botrana</i> (Denis et Schiffermüller) (Lepidoptera: Tortricidae) collected as larvae from grapevine (<i>Vitis vinifera</i> L.) and flax-leaved daphne (&...

| description | We analysed electroantennogram (EAG) responses of male and female adults of the European grapevine moth <i>Lobesia botrana</i> (Denis et Schiffermüller) (Lepidoptera: Tortricidae) collected as larvae from grapevine (<i>Vitis vinifera</i> L.) and flax-leaved daphne (<i>Daphne gnidium</i> L.). The host-plant odorants tested were either <i>V. vinifera</i>-specific [1-octen-3-ol, (<i>E</i>)-β-farnesene, (<i>E</i>)-4,8-dimethyl-1,3,7-nonatriene], <i>D. gnidium</i>-specific (2-ethyl-hexan-1-ol, benzothiazole, linalool-oxide, ethyl benzanoate), or were shared by both host-plants (linalool, methyl salicylate). Sex pheromone compounds were also tested. The male response to the major pheromone component (<i>E</i>7,<i>Z</i>9-12:Ac) was higher than to any other stimuli, whereas the response to the minor pheromone components (<i>E</i>7,<i>Z</i>9-12:OH and <i>Z</i>9-12:Ac) was not different from the response to the plant odorants. The female response to pheromone was lower or not different from that to plant odorants. Methyl salicylate elicited a higher response in females and (<i>E</i>)-β-farnesene elicited a higher response than several other plant odorants in both sexes. Non-significant interactions between host-plant odorant and sex indicated an absence of sex specialization for host-plant volatile detection. The lack of a significant interaction between plant volatiles and larval host-plants suggested that there was no specialization for plant-volatile detection between <i>V. vinifera</i> and <i>D. gnidium</i> individuals. |
