Abstract
Mass trapping Cosmopolites sordidus using a pheromone-baited pitfall trap and Metamasius hemipterus using a pheromone-sugarcane-baited open gallon trap was conducted in commercial plantain and banana. Four traps for each insect per ha were placed in each of three 1 ha plots of plantain and two 5 ha plots of banana during 10-17 months. Capture rates of C. sordidus and M. hemipterus in both plantain and banana declined by 75 over 10-12 months. Corm damage decreased by 61-64 over the same period. Fruit bunch weights increased by 27 in plantain and 23 in bananas relative to control plots after 11-12 months of trapping. Trapping only for C. sordidus in two large plantations 232-249 ha each reduced corm damage by 62-86 relative to pretrapping levels after 4-5 months. After completion of these trials a new above ground ramp trap was developed for C. sordidus that is 25 more effective than the pitfall trap.
