| Abstract: | "The Oriental fruit fly, Bactrocera dorsalis (Hendel) is an economically devastating pest of fruit crops across the globe with stringent quarantine restrictions to limit its further spread. The current management programs increasingly depend on male annihilation but trapping female flies is equally important to reduce fruit damage. Considering the importance of kairomones in courtship and oviposition site selection behavior of B. dorsalis, the aim of this work was to isolate and identify potential cues from the volatiles of arils of jackfruit, Artocarpus heterophyllus. Using olfactometer assays and gas-chromatography linked to electroantennographic detection, attraction of both female and male B. dorsalis to specific jackfruit volatiles was demonstrated. Ethyl 3-methylbutanoate, ethyl hexanoate, pentyl butanote, 2-methylbutyl 3-methylbutanoate, 2-methylpropyl hexanoate, (Z)-3-hexenyl 3-methylbutanoate and dodecanal were found to attract female B. dorsalis specifically. Butyl acetate, 2 phenylethanol and pentyl 3-methylbutanoate elicited attraction in male B. dorsalis only. Synthetic blends of these compounds were found to attract female and male B. dorsalis in laboratory as well as field conditions. Using specific cues common to each set, a blend of methyl 3-methylbutanoate, butyl acetate, 3-methylbutyl acetate and hexyl acetate attracted both sexes of B dorsalis. This study demonstrates the use of kairomone-based lures for sex-specific as well as bisexual attraction for the first time" |
