【Background】Chlumetia transverse Walker seriously damages inflorescence and tender tip and expands its distributed areas incessantly, which has caused great losses to south of China. 【Method】Chemical constituents and their relative content of mango volatiles at different parts (flowers, shoots and mature fruits) were comparatively analyzed by gas chromatographymass spectrometry (GC-MS). Electroantennogram (EAG) was employed to record the electrophysiological responses of different gender and mating state of C.transverse adults to twelve of the volatiles. 【Result】The major volatile components from flowers, shoots and fruits were terpenes. The numbers of major terpenes (relative content over 0.06%) were 22, 11 and 13 in flowers, shoots and fruits, respectively. The major volatile components in flowers were α-phellandrene (43.64%) and terpinolene (29.33%), while α-urjunene (23.63%)and β-carypohyllene (29.47%) predominated in shoots and fruits, respectively. There were only 2 common components, terpinolene and β-cubebene that had different relative content at various plant parts. The relative contents of terpinolene were 29.33%, 19.99%, 0.59%, and that of β-cubebene were 3.51%, 2.18%, 6.05% in blossom, shoot and fruit, respectively. EAG response relative values in virgin female, unmated male, mated female and mated male individuals of C.transverse to the same compound did not show significant differences (P＞0.05). The EAG responses to trans-2-hexen-1-al were significantly different from EAG responses to other compounds in both mated and unmated adults. The EAG responses in virgin females and unmated males were a bit higher than that of mated female and male, but not significantly. 【Conclusion and significance】We could develop the sex pheromone attractant of C.transverseby using trans-2-hexen-1-al as an synergistic agent. The study maybe provide an scientific basis for expounding harmfulness mechanism of C.transverse from the point of view of chemical signal.
