Management of the Banana Weevil (Cosmopolites sordidus) Menace using Mass Trapping approaches. A review

The banana weevil Cosmopolites sordidus is an important pest in plantain and banana crops throughout the world. The objective was to evaluate a mass trapping system based on traps baited with synthetic pheromone (sordidin) + plantain corm tissue to reduce C. sordidus populations and damage in the Centro-Chontalpa region of Tabasco state, Mexico. The experiment was carried out on plots of about two to three hectares of Horn plantain Musa AAB infested by C. sordidus. Treatments were four traps ha-1, eight traps ha-1 and a control (without traps). Population density and damage in corms of small plants (suckers) were reduced after six months of mass trapping, while damage in corms of mature plants (freshly harvested) only decreased signi cantly after 13 months of trapping. By doubling the number of traps, the reduction in the C. sordidus population and damage was not signi cant. The use of four traps ha-1 baited with synthetic pheromone + plantain corm is a technically feasible strategy that provides at least partial control of this pest under local Horn plantain production conditions.

AbstractThe effects of host and non-host plant odours on the foraging responses of the banana weevil, Cosmopolites sordidus (Germar), were investigated in the laboratory through arena and olfactometer bioassays. Contrary to previous reports that banana rhizome and pseudostem were the most attractive parts to the weevil, dead leaves were most preferred. Comparison of dead banana leaves with dead leaves of other plants showed that attractant odours were present in yam, cocoyam and dead grasses but absent in cocoa and soybean leaves. Complete leaf senescence while the leaf was attached to the mother plant proved necessary for the development of the dead-leaf-based odours but the involvement of microbial organisms could not be demonstrated. It is possible that dead-leaf-based attractants could be used in combination with microbials such as entomogenous fungi and nematodes in integrated management of C. sordidus.
