Ecological aspects of a Cosmopolites sordidus (Germar) (Coleoptera: Curculionidae) population in São Miguel do Iguaçu, PR./
Aspectos ecológicos da população de Cosmopolites sordidus, (Germar) (Coleoptera: Curculionidae) em São Miguel do Iguaçu, PR

Semina: Ciências Agrárias, 2006
The population dynamics of Cosmopolites sordidus (Germar) was studied in banana crops (cultivar Nanicão) at São Miguel do Iguaçu, PR, using roof-tile-like baits, between June/2003 and May/2004. Adults infected by entomopathogenic fungi were recorded, and

1,8-Cineole: An attractant for the banana weevil, Cosmopolites sordidus

Phytochemistry, 1996
1,8-Cineole was identified as one of the electrophysiologically active components of the volatiles from banana cultivars susceptible to the banana weevil. It was also shown to be an attractant for the banana weevil Comopolites sordidus in laboratory behavioural bioassays. The resistant cultivar did not contain 1,8-cineole.

First natural occurrence of the entomopathogenic fungus Beauveria bassiana (Bals. Criv.) Vuill. on Cosmopolites sordidus (Germar, 1824) (Curculionidae, Coleoptera) in an agroforestry system in the Brazilian Cerrado [PDF]

Check List
The natural occurrence of the fungus Beauveria bassiana is an indicator of environmental balance. When the agroforestry system naturally presents this entomopathogenic fungus on the banana weevil Cosmopolites sordidus, a pest insect in the banana crops ...

Falsa broca aumenta disseminação de Beauveria bassiana em populações de campo da broca-do-rizoma da bananeira West Indian Sugarcane Weevil enhances dissemination of Beauveria bassiana on field populations of the banana weevil

Ciência Rural, 2011
A transmissão horizontal de fungos entomopatogênicos tem papel importante na epizootiologia, pois está diretamente associada à disseminação do agente causal da doença de insetos.

Deleterious effects of plant cystatins against the banana weevil Cosmopolites sordidus [PDF]

Archives of Insect Biochemistry and Physiology, 2009
AbstractThe general potential of plant cystatins for the development of insect‐resistant transgenic plants still remains to be established given the natural ability of several insects to compensate for the loss of digestive cysteine protease activities.

Susceptibility of Cosmopolites sordidus (Germar) (Coleoptera: Curculionidae) to Heterorhabditis sp. (Poinar), Steinernema feltiae (Filipjev) and isolates of entomopathogenic fungi

Egyptian Journal of Biological Pest Control, 2023
Background The weevils Cosmopolites sordidus (Germar), Metamasius hemipterus (Linnaeus), and M. hebetatus (Gyllenhal) (Coleoptera: Curculionidae) form a complex of important pests of plantain crops, causing crop losses of over 60%.

COSMOS, a spatially explicit model to simulate the epidemiology of Cosmopolites sordidus in banana fields [PDF]

Ecological Modelling, 2009
A stochastic individual-based model called COSMOS was developed to simulate the epidemiology of banana weevil Cosmopolites sordidus, a major pest of banana fields. The model is based on simple rules of local movement of adults, egg laying of females, development and mortality, and infestation of larvae inside the banana plants.

Plantain hybrids for the humid forest agroecology of Central Africa – diseases and pests load, fruit yield and farmers perception

Plant Production Science, 2022
Plantain is one of the major staples contributing to food security and income generation in West and Central Africa. Local cultivars in Cameroon are susceptible to pests and diseases causing severe losses in plantain production.
