ESTUDIO DE LA ENTOMOFAUNA DE GENOTIPOS DE FRIJOL POR MEDIO DE ANÁLISIS MULTIVARIADO

There are several species of insects that can cause damage to productivity and natural enemies that can help to regulate populations in beans cultivation. The objective of the present study was to evaluate the entomofauna associated with 20 bean genotypes and correlate the interaction between insects using multivariate analysis. The most abundant species in the studied system were Sternechus subsignatus Boheman, 1836 (Curculionidae: Sternechini), Euschistus heros (Hemiptera: Pentatomidae), and Diabrotica speciosa (Coleoptera: Chrysomelidae). All three species showed direct correlation with each other. The bean crop under study presented three species of stinkbugs considered important pests. The species Cerotoma arcuata (Coleoptera: Chrysomelidae) and Edessa meditabunda (Hemiptera: Pentatomidae) presented inverse correlation with each other.
