Aspectos biológicos de Zabrotes subfasciatus (Bohemann, 1833) (Coleoptera, Bruchidae) em Phaseolus vulgaris L., cv. Carioca (Fabaceae), sob condições de laboratório

Zabrotes subfasciatus is a serious pest of common beans, P. vulgaris L.. In Brazil there are several studies dealing with resistance of bean genotypes to this insect, while other studies have emphasized the utilization of oils and powders from plants to repel their attack. In this paper, fecundity, fertility, pattern of oviposition, life cycle and longevity were evaluated for a Brazilian stock from the Goiás State on P. vulgaris cv. Carioca, at 30ºC and 70% R.H. The mean fecundity was 38 eggs per female and 73% of viability. Egg laying showed an aggregated pattern. Males and females lived an average of 13 and 9 days, respectively. The total life cycle lasted for about 28 days.
