The Humidity Behavior of Cosmopolites sordidus (Coleoptera: Curculionidae)
Annals of the Entomological Society of America, 1963Adult banana root borers were exposed to various relative humidity gradients in small circular arenas and their distributions in the dry and wet halves of the gradient were recorded. Different humidities were provided over water, graded solutions of KOH, or “Drierite” (anhydrous CaSO4).

Migration potential of the banana weevil Cosmopolites sordidus
Agricultural and Forest Entomology, 2011The banana weevil Cosmopolites sordidus Germar (Coleoptera: Curculionidae) is a major pest in banana ( Musa spp.) growing areas. The weevil is known to be

Ant abundance and Cosmopolites sordidus damage in plantain fields as affected by intercropping [PDF]
Biological Control, 2015 Intercropping is a practical way to increase plant diversity in agroecosystems and provide alternative food and habitat to arthropods, including generalist predators. In tropical agriculture, ants are important predators and have complex and often strong effects on pests.

Mass trapping Cosmopolites sordidus (Coleoptera, Curculionidae) using a pheromone-baited pitfall trap and Metamasius hemipterus (Coleoptera, Curculionidae) using a pheromone-sugarcane-baited open gallon trap was conducted in commercial banana. Four traps for each insect per hectare were placed in each of two 5-hectare plots of banana.

Components of resistance to banana weevil (Cosmopolites sordidus) in Musa germplasm in Uganda
Entomologia Experimentalis et Applicata, 2006AbstractA field screening trial undertaken in Uganda showed that a number of Musa L. (Musaceae) cultivars and hybrids displayed high levels of resistance to banana weevil, Cosmopolites sordidus (Germar) (Coleoptera: Curculionidae), while most highland banana cultivars tended to be susceptible to weevil attack.

Studies were conducted in Uganda to evaluate the influence of distance, environmental factors, trap location and trap type on catches of Cosmopolites sordidus (Germar) (Coleoptera: Curculionidae) in pheromone-baited traps. Marked weevils were released at recorded locations within plots.

The banana root borer Cosmopolites sordidus (Germar) (Coleoptera: Curculionidae) is a major pest of bananas throughout the world. Chemical control is both undesirable and expensive, where biological control alternatives are limited, and pheromone-based trapping results in low captures.

Population genetic structure of banana corm weevil Cosmopolites sordidus (Germar) in India
Journal of Asia-Pacific Entomology, 2018Abstract The population genetic structure of Cosmopolites sordidus (Germar), an economically important pest of bananas, was studied using the sequence data of the internal transcribed rDNA (ITS1+ITS2) and the mitochondrial ‘COI-tRNALeu-COII’ region from seventy nine individuals collected from six sampling locations in India. The ITS data revealed 70%

Effects of mulch on banana weevil Cosmopolites sordidus (Germar) populations and damage in Uganda
Crop Protection, 2006Abstract Mulches have been shown to encourage banana weevils, presumably through enhanced water conservation. Some farmers report that leaving the soil at base of the banana mat free of mulch reduces banana weevil damage. Trials were conducted at the Kawanda Agriculture Research Institute and on a farm in Ntungamo District, Uganda to investigate the ...
