Novel rain-fast bait stations for applications of insecticidal baits to control pestiferous fruit flies (Tephritidae) in Hawaii

We developed in Hawaii a novel rain-fast bait stations for applications of protein baits (e.g., GF-120 Fruit Fly Bait) to control fruit flies (Tephritidae), in particular Oriental fruit fly (Bactrocera dorsalis) and melon fly (B. cucurbitae). These bait stations take advantage of the flies’ need for shelter and their strong response to colored objects while protecting GF-120 against rainfall. Results from research conducted with oriental fruit fly under semi-field and field conditions in Hawaii indicate excellent performance of these devices while achieving a reduction in the amount of GF-120 used per hectare in papaya orchards. The novel bait stations developed represent a simple, efficient and economical way of controlling fruit flies and a safer alternative to foliar sprays.
