Development of Improved Attractants and their Integration into Fruit Fly SIT Management Programmes

Objective:

To develop a trapping system for female fruit flies to improve sensitivity of trapping networks used in large scale SIT control programmes. To develop a trapping system for female fruit flies which will be used in practical SIT programmes using a genetic sexing strain, i.e. where only sterile males are released.

Activities:

After the successful development of the medfly female attractant 3CL (a combination of two female attractants: ammonium acetate and putrescine, supplemented with a third component, trimethylamine), experiments were conducted to evaluate these female attractants and other attractants that have showed potential for other fruit flies that occur in different regions worldwide including the economic species of the genus Anastrepha, Ceratitis (other than capitata) and Bactrocera. These attractants were tested in different traps, dry and wet traps, including the conventional closed bottom dry trap, a new open-bottom try trap with a sticky insert and the Plastic Multilure McPhail trap. Efforts also target at developing a set of standard detection and monitoring methods for major fruit flies. The global economic importance of fruit fly control requires standardization of detection systems among regions encountering subtropical and tropical Tephritid pests. The CRP will provide comparative standards among pest species and regions, and the integrations of female trapping systems with SIT management programs.

Participants:
