Abstract:
Bactrocera species are a significant agricultural pest of various fruits and cucurbit crops. The geographical distribution of Bactrocera is found in tropical and subtropical regions around the globe. It prefers to live in warm, and humid environments. Meanwhile, the management’s over-reliance on chemical control methods can lead to the evolution of resistance, reducing the efficacy of pesticides and complicating pest management efforts. The current study was based on understanding the role of pheromones in Bactrocera species. The following pheromone components: zingerone (ZR), raspberry ketone (RK), and cuelure (CL), have been used at different concentrations 10000, 1000, 100, 10, 1, 0.1 µg /ml for B. cucurbitae. Meanwhile, 2-allyl-4,5-dimethoxyphenol (DMP), and Z-coniferyl alcohol (Z-CF) were used for B. zonata at 20, and 2.5 µg /ml. The observations were made by employing a Y-tube olfactometer. The results revealed that females of B. cucurbitae showed significant attraction towards pheromones at low concentrations, however, males of B. cucurbitae showed attraction towards pheromones at higher concentrations. The female showed significant response time at 0.1 µg /ml, 1 µg /ml and 1 µg /ml, while, the male showed significant response time at 100 µg /ml, 10000 µg /ml, and 100 µg /ml, against ZR, RK, and CL, respectively. Additionally, males of B. zonata showed significant attraction towards DMP and Z-CF compared to females at 10 µg /ml. Collectively, the results may provide significant insight into existing monitoring and developing eco-friendly strategies for managing Bactrocera spp.
