Atividade inseticida do extrato etanólico de folhas de Zingiber officinale sobre o desenvolvimento do inseto Callosobruchus maculatus (Fab.).

Abstract

The cowpea has great nutritional and economic importance in Brazil, more precisely in the Northeast. The same has a culture of easy adaptation and is tolerant to drought periods. However, when attacked by pests such as Callosobruchus maculatus, its grains show great loss of nutritional value and germination value. The presence of the weevil is most frequent during the grain storage. However, the use of chemicals to combat this pest can cause environmental damage from the poisoning of applicators. So no need to study substances of plant origin to combat this pest, and the search for plant extracts with insecticidal activity is a relevant strategy.
