Do you want to bet on baits? An evaluation of Various Baits for Jackfruit Fruit Fly, Bactrocera umbrosa Fabr. (Diptera: Tephritidae)

Resumen

The efficiency of the various baits namely: baker’s yeast, brewer’s yeast and pheromone on fruit flies, Bactrocera umbrosa Fabr. was studied under the laboratory and field conditions. In the laboratory, 120 starved fruit flies were subjected to experiment in a choice test. The field trapping experiment was conducted at the Pomology Experimental Station of theVisayasStateUniversity, Visca,BaybayCity,Leyte using an improvised yellow trap to test the effectiveness of the yeast-based baits and pheromone as baits to the insect under field condition. The laboratory assay experiment showed that pheromone attracts the most number of flies compared to other treatments. However, only males are attracted to pheromone. It is followed by the baker’s and brewer’s yeast which attracted both female and male flies. In field trapping, results showed that pheromone, and yeast-based baits were able to trap flies. Nonetheless, pheromone significantly trapped the number of flies. Thus, pheromone is the most effective amongst treatments while yeast-based baits showed potential results and merit further study to optimize its use.
