The main objective of the present study was to evaluate the efficacy of lesser date moth, Batrachedra amydraula, sex pheromone lure and its longevity in harsh desert climate. Various trap types and height have been studied for traps baited with B. amydraula pheromone lure. Results indicated that an average of 11.33 males/trap/week was captured on traps baited B. amydraula lure during the last week of April, which represents the onset of insect in the field. The highest rate of trap catches was recorded as 20 males/trap/week during the first week of May. Around 90% of the moths were emerged during these two weeks. B. amydraula pheromone lure remained effective over a period 7-8 weeks. Traps which placed at a height of three meters from the ground level were found more efficient than those suspended at six meters. An average of trap catches was 1.99-5.32 males/trap/week for traps placed at three meters height and whereas 1-3.99 males/trap/week was recorded on traps placed in six meters height. Delta trap was found more effective than funnel traps when applied against B. amydraula.展开更多
