Onion thrips, Thrips tabacis Lindeman (Thysanoptera: Thripidae) is an important pest of horticulture crops
throughout the globe. However, there is a paucity of studies on its behavioral ecology in relation to herbivore induced
plant volatiles (HIPVs). An attempt was made to study behaviour of T. tabaci towards HIPVs and healthy plant
volatiles. Olfactometer bioassays revealed that T. tabaci significantly preferred HIPVs from conspecific infested
onion to volatiles from healthy onion plants. Gas chromatography-Mass spectrometry (GC-MS) analysis of HIPVs
and volatiles from healthy onion plants revealed substantial changes in their volatile profiles. Our study provides
empirical data on signals HIPVs may provide herbivores and suggests that the role of HIPVs, mostly generalized as
defense, may vary based on the interaction and must be studied closely to understand their ecological roles. It also
provides basis for the development of kairomone based management strategies against this devastating pest.
