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.

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.

Fluctuación poblacional y dispersión del Picudo Negro del plátano Cosmopolites sordidus (Germar)

Revista Colombiana de Entomología, 1986
Con el fin de saber qué ocurre cuando una plantación de plátano atacada por Cos­mopolites sordidus Germar es qué influencia tiene la húme­dad del suelo y el exceso hí­drico en el suelo sobre el nú­mero de adultos capturados en dos tipos de cebos o tram­pas, se realizo este trabajo en la hacienda "Naranjal" Muni­cipio de Chinchiná (Caldas), en una ...
