Efeito de Secreções da Glândula Mandibular de Atta sexdens rubropilosa Forel (Hymenoptera: Formicidae) Sobre a Germinação de Conídios de Botrytis cinerea Pers. Fr.

Abstract

*[This research investigated the effect of mandibular gland secretions of Atta sexdens rubropilosa Forel on the germination of Botrytis cinerea Pers. Fr. conidia, a fungus attacking several species of economicaly important cultivated plants. From 20 mandibular glands of workers of the leaf-cutting ant (3.60-4.30 mm head capsule width), we obtained 9.4 mg of acetone soluble secretion. Results by Probit analysis of data indicated that higher gland concentrations led to higher inhibition of conidia germination. The concentration of 18.80 mg/ml had an inhibitory effect (94.2%) similar to that of Mancozeb (95.3%).]
