Conteúdo: | Callosobruchus maculatus (F.) (Coleoptera: Chrysomelidae) is an important pest of stored cowpea seeds (Vigna unguiculata) (L.) Walpers and the infestation of these seeds by the pest is a limitation to their production. Many studies have identified V. unguiculata genotypes that were resistant to the insect infestation. These resistant genotypes can lead to a reduction on the use of insecticides, avoiding environmental and food contamination. In this work, we evaluated the resistance or susceptibility of different V. unguiculata genotypes to infestation by C. maculatus. Our results showed that the number of eggs laid by C. maculatus varied from 6 to 13 eggs per seed among genotypes. Almost all the eggs were viable, and the larvae hatched at 5 days after oviposition (DAO).
