Resumen

HERNANDEZ-FUENTES, Luis M. et al. Control del barrenador de las semillas, Bephratelloides cubensis Ashmead (Hymenoptera: Eurytomidae) en guanábana, Annona muricata L. (Annonales: Annonaceae). Acta Zool. Mex [online]. 2008, vol.24, n.1, pp.199-206. ISSN 2448-8445.

The insecticides dimethoate, malathion, ethyl-chlorpyriphos, cipermetrine, endosulphan and azadirachtine were evaluated for controlling the seed borer B. cubensis on soursop under field conditions. Dosage of 40, 150, 48, 40, 94.5 and 30 g of active ingredient in 100 L of water, respectively, were used. Likewise, pocketing of fruits with organdi mesh and perforated, transparent plastic bags to avoid humidity accumulation were evaluated. The experiment was repeated twice. The evaluated variable was percentage of infested seeds. Pocketing of fruits with organdi mesh was the best treatment (0.0 and 1.6 % of infestation). The fruits covered with plastic bags showed zero percent of infestation, but these displayed burn spots and a decrease in growth. Dimethoate was the best insecticide treatment (0.75 and 5.9 % of damage), followed by cipermetrine (0.8 and 17.83 % of damage).

Palabras llave : Bephratelloides cubensis; soursop; control.
