A study was carried out to evaluate the efficiency of different types of plantain pseudostem traps for the capture of adult insects of Cosmopolites sordidus and Metamasius hemipterus (Coleoptera: Curculionidae), in a commercial plot of plantains in the province of Bocas del Toro, Panama. The types of traps evaluated were: i) Sandwich; ii) Disk; iii) Sandwich with pesticide; iv) Hinge. The experimental design was randomized complete blocks (RCBD), composed of four blocks and four treatments. The insects’ collection was carried out every two days after placing the traps and for the statistical analyses, the total number of insects accumulated per experimental unit was taken into consideration. According to the results (p = 0,07), no significant differences were found between treatments and only adult specimens of Cosmopolites sordidus could be captured. However, the highest catch on average was achieved with the sandwich trap. These preliminary results would be close to depending less on the use of pesticides to control these pests, although further research is required.
