I am a leaf on the wind watch me as i splat12/18/2023 ![]() Why males respond to these lures was unknown until recently, but numerous studies (e.g., ) have now demonstrated that feeding on lures enhances male sexual behavior and signaling, which results in increased mating success. ![]() It is widely believed, and limited field data support, that ME is a more powerful attractant than RK/CL. ![]() In the subfamily Dacini, males of the genera Bactrocera Macquart and Zeugodacus Hendel may be categorized broadly as responding either to methyl eugenol (ME) or raspberry ketone (RK) or its hydrolyzed form cue-lure (CL) (but see for recent data challenging this classification). Males of many species of true fruit flies (Diptera: Tephritidae) are attracted to a small set of plant-derived secondary compounds termed male lures. Additional research in areas where MAT programs are currently undertaken would be helpful to corroborate this study’s findings. dorsalis through reduced material use, labor costs, and higher effectiveness. This study suggests that benefits for control and eradication programs would result from reducing the application density of MAT against B. Spatial analysis of the recapture patterns of the first trap service per replicate x treatment reveals similar positional effects for all grid densities despite differences in overall percent kill. We also estimated slightly higher average kill for any given density for weathered grids compared with fresh. Counterintuitively, we observed decreasing effectiveness (percent kill) with increasing application density. dorsalis males released under three experimental SPLAT-MAT-ME site densities (110, 220, and 440 per km 2) near Hilo, Hawaii using both fresh and aged traps to evaluate the effectiveness of varying densities and how weathering of the SPLAT-MAT-ME formulation influenced any density effects observed. We conducted direct comparisons of trap captures of marked B. In the case of Bactrocera dorsalis (Hendel), a highly invasive and destructive species, current implementations of MAT utilize a combination of the male attractant methyl eugenol (ME) and a toxicant such as spinosad (“SPLAT-MAT-ME”) applied at a high density with the goal of attracting and killing an extremely high proportion of males. Male Annihilation Technique (MAT) is a key tool to suppress or eradicate pestiferous tephritid fruit flies for which there exist powerful male lures.
