“…However, in an on-station trial, Masanza et al [48] found that crop sanitation reduced C. sordidus adult populations but did not affect damage or yield levels during the duration of the trial. In Tanzania, Rannestad et al [49] found that crop sanitation combined with trapping reduced C. sordidus populations by 33 to 74%. Despite the labor intensity associated with crop sanitation in reduction in the yield loss due to C. sordidus damage, it remains a reliable technology to promote to affect banana farming community.…”

The banana weevil Cosmopolites sordidus (Germar) (Coleoptera: Curculionidae] is a major pest of East African highland bananas and plantains. Its larvae bore in corm tissue damaging the root system, disrupting nutrient and water uptake, compromising plant anchorage, reducing yield, and shortening plantation life. Yield losses in bananas and plantains may exceed 50%. Available technologies for the management of the pest include cultural control, biological control, and chemical control. These methods may be costly, labor intensive, or ecologically unsustainable. Such effects, together with developed pesticide resistance, have led to various efforts searching for sustainable alternatives. To achieve this, there is a need to understand the biology of the pest and the currently available management options which includes use of cultural practices, resistant banana varieties, biological and microbial control, pheromone trapping and chemical and botanical insecticides. This article reviews the research status concerning C. sordidus biology, distribution, management options, including current innovations such as genome editing, and suggests future research directions for the management of the pest. Research findings suggest that no single control strategy will provide complete control. The integration of appropriate conventional C. sordidus management options with genetic engineering and other ecologically friendly methods such as use of botanicals and infochemicals will manage the pest and sustainably increase banana production.

Alternatives to synthetic pesticides for the management of the banana borer weevil ( Cosmopolites sordidus ) (Coleoptera: Curculioniidae)

Bananas and plantains are important staple crops for many people in developing countries, but these crops are severely affected by biotic constraints that reduce productivity. A major biotic stress is the banana corm borer weevil (C. sordidus) whose larvae eat corm/pseudostem tissues that eventually weaken the plants and cause toppling. To manage these borer weevils, most farmers use synthetic pesticides with active ingredients from different pesticide groups. Over reliance and abusive use of pesticides result in detrimental effects on the environment and human health. These effects together with ecological backlashes such as development of resistance by the pest have led to numerous advocacies to minimize the use of these chemicals. To achieve this, there has been increasing number of researches to seek sustainable alternatives that could be used to replace these synthetic pesticides or be integrated with less toxic chemicals to effectively manage the pest. This review summarizes global research on the use of synthetic pesticides and alternative management techniques such as the use of appropriate cultural practices (e.g., clean planting materials, fallowing, mulching, intercropping, and trapping), botanical pesticides (e.g., from Solanaceae, Asteraceae, and Meliaceae), entomopathogens, predators/parasitoids, and the use of resistant crop varieties, as well as possibilities of engineering phytocystatins to produce transgenic varieties that will be harmful to weevil. The review ends with conclusions, limitations/gaps, and recommendations for future research for the different alternative options.
