Preference of Cosmopolites sordidus for fusarium wilt‐diseased banana plants

Journal of Applied Entomology, 2022
AbstractThe objective of this study was to understand the role of Cosmopolites sordidus in the dispersal of Fusarium oxysporum f. sp. cubense race 1 (Foc) and more specifically to determine whether C. sordidus is preferentially attracted to Foc‐contaminated banana plant material vs. Foc‐free material. The attraction of C.

The Humidity Behavior of Cosmopolites sordidus (Coleoptera: Curculionidae)

Annals of the Entomological Society of America, 1963
Adult 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).

Efficient Synthesis of Sordidin, A Male Pheromone Compound Emitted by Cosmopolites Sordidus

Synthetic Communications, 1996
Abstract A multigram-scale synthesis of sordidin ((IS∗,3R∗,5R∗,7S∗) 2,8-dioxa 1-ethyl 3,5,7-trimethyl bicylo [3,2,1] octane) is described. Sordidin is obtained as a racemic mixture of its four isomers 1a-d (10 steps, 27% overall yield)

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.

Components of resistance to banana weevil (Cosmopolites sordidus) in Musa germplasm in Uganda

Entomologia Experimentalis et Applicata, 2006
AbstractA 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.

Factors influencing pheromone trap effectiveness in attracting the banana weevil,Cosmopolites sordidus

International Journal of Pest Management, 2005
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.

Effects of mulch on banana weevil Cosmopolites sordidus (Germar) populations and damage in Uganda

Crop Protection, 2006
Abstract 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 ...
