With an objective to develop a novel single parapheromone synergistic to attract both Bactrocera dorsalis and Bactrocera correcta, this combination of synergist with parapheromone is developed to attract males of both the species. This technology attracts a large number of male flies of multiple species, mainly B. correcta (Guava Fruit fly) and B. dorsalis. The methodology is simple and involves the mixing of synergist with parapheromone (ME) in an adjunct or emulsifier and the raw materials are also readily available.
