Efficacy of SPLAT in entrapping the invasive insect pest Red Palm Weevil in Toddy farming areas of Nizamabad, Telangana, India

Red Palm Weevil, RPW, SPLAT, Pheromones, Invasive InsectsAbstract
The red palm weevil (RPW, Rhynchophorus ferrugineus) (Oliver) an invasive insect pest of coconut, oil palm, date palm and sago across the globe and continued to spread to different parts of India damaging the palm trees within months following infestation. However, very little research is focused on RPW a serious insect pest which is threatening the very existence of palm trees particularly toddy plants. Toddy cultivation is an important food source for several communities across the Telangana, India. Therefore, we have developed Specialized Pheromone and Lure Application Technology (SPLAT) technology for effective trap of RPW. For trapping RPW, SPLAT-1 and SPLAT-2 in combinations with food bait (sugarcane, apple and banana) and insecticide has attracted a greater number of insects when compared to individual application within a period of one month. Interestingly, both male and female populations (more females) were captured due to attractive nature of ferrugineol. From the current studies, it is strongly recommended to combine bait and insecticides along with the SPLAT for efficient capture of RPW to control its widespread across the globe.
