Article Title: Sensilla Morphology and Complex Expression Pattern of Odorant Binding Proteins in the Vetch Aphid Megoura viciae (Hemiptera: Aphididae)
Figure Lengend Snippet: Behavioral responses of M. viciae to the main compounds identified in the insect’s cornicle secretions and to the mixture containing (E)-β-farnesene 14.2%, (–)-α-pinene 11.8%, β-pinene 74%. The repellency index R was calculated by the formula R = (C–T)/(C+T), where T indicates the number of aphids in the arm with the compound to be tested and C, those in the control arm. Asterisks indicate that the repellence observed is significantly different from the control ( ∗ p
Article Snippet: Tested compounds were (E)-β-farnesene (Bedoukian Research, Danbury, CT, United States), (±)-α-pinene, β-pinene, (-)-α-pinene, (+)-limonene, hexane (Sigma-Aldrich-Fluka) and a mixture comprising (E)-β-farnesene 14.2%, (-)-α-pinene 11.8% and β-pinene 74% ( ).
