Olfactory Responses of Banana Weevil Predators to Volatiles from Banana Pseudostem Tissue and Synthetic Pheromone [PDF]

open access: yesJournal of Chemical Ecology, 2005
As a response to attack by herbivores, plants can emit a variety of volatile substances that attract natural enemies of these insect pests. Predators of the banana weevil, Cosmopolites sordidus (Germar) (Coleoptera: Curculionidae) such as Dactylosternum abdominale (Coleoptera: Hydrophilidae) and Pheidole megacephala (Hymenoptera: Formicidae), are ...

Reduction of banana weevil populations with pseudostem traps

International Journal of Pest Management, 1994
Abstract One‐week‐old traps made from split banana pseudostems were 1.5–1.7‐fold more attractive to adult banana weevils than 2–3‐week‐old traps. In one experiment, all available pseudostem material was used for trapping, and weekly collecting of weevils over an 11‐month trapping period led to a 50% reduction in weevil catches in one field.

Response of banana cultivars to banana weevil attack [PDF]

open access: yes, 2016
East African Highland Bananas (EAHB) (Musa AAA, 'Matooke' group) are a major staple food in the East African region. However, banana weevil (Cosmopolites sorllidus) is a major production constraint to  bananas and may cause damage levels of up to 100%. Pesticides can effectively control banana weevil but these are unaffordable by resource poor farmers,

Influence of a cover crop on ants and dermapterans in banana plantations: consequences for the regulation of the banana weevil

International Journal of Pest Management, 2022
The banana weevil Cosmopolites sordidus Germar is the most important pest of banana and plantain. In banana agroecosystems, cover cropping is a practice that prevents the use of herbicides and may provide natural habitats for generalist predators. Here, we assessed the effect of a cover crop, Paspalum notatum Flüggé on the ant community, dermapterans ...
