Abstract
About 138 volatile chemicals emitted by mango (Mangifera indica) flowers at full bloom stage were identified by gas chromatography-mass spectrometry (GC-MS). Olfactory attraction of virgin female weevils to 30 single components and blends of selected chemicals were investigated by behavioral bioassays for attractancy. Weevils were attracted to volatile chemicals emitted by mango flowers when tested in Y-tube bioassays. Acetic acid and decane, in concentrations equivalent to 10 panicles, significantly elicited responses at 66.7% when tested separately. A blend of these components resulted in weaker response from the weevils. Further bioassays led to the identification of a six-component blend that was 70% attractive to the mango pulp weevil. This blend consisted of: acetic acid, decane, acetone, linalool, ethyl benzoate and 2-methyl heptenone. Results of the study provide the first evidence for mango pulp weevil attraction to specific compounds present in its mango host.
