Research Interest
Pheromones are species-specific chemical signals, involved for communication among individuals. The phreomone signals play an integral part in mediating reproductive interaction in many mammals and can yield information about an animal such as identity, social status and sex.  Such signals have rarely been considered in birds, but recent results have shown that chemical signals are actually used by different bird species to find food and to recognize their home and nest. Bats are the only mammals that can fly. Bats are actually quite harmless and are important indicators of a healthy eco-system.  Most of the wildlife bats suffer from habitat loss due to ecological succession. Investigating the role of chemical signals and providing a suitable solution through chemo signals for bat conservation will enhance sexual potentiality and productivity in this endangered species. Since there is no report in the bat pheromones, it is worthwhile to identify and analyze the bioactivity of individual volatile compounds in the bats sources.
