“…Bruchids are attacked by several pteromalid parasitoids in storage (Southgate 1979). Among them, D. basalis is an important cosmopolitan pteromalid larval-pupal solitary ectoparasitoid attacking the pulse beetle, C. chinensis (Damiens et al 2001;Dugravot et al 2002;Rojas et al 2005;Amevoin et al 2007). This species is now found in many warmer countries like Nigeria, South Africa, Sudan, West Africa and Bangladesh (Qumruzzaman 2003;Sanon et al 2005).…”

“…The eggs of this insect are deposited on the surface of the grains and the larvae develop inside, causing considerable weight loss, reduction in germination, decreased nutritional quality and commercial devaluation (Oliveira & Vendramim, 1999). Furthermore, the metabolism of the larvae causes an increase of the temperature in the storage containers, which favors the development of fungi capable of producing toxins (such as aflatoxin) dangerous to the health of the consumer (Amevoin et al, 2007).…”

Cowpea (Vigna unguiculata (L.) Walp.) when stored is mainly attacked by bruchid Coleopterans. The control of these pests is done primarily through chemicals, however, with problems related to the selection of resistant insects, alternative forms of control are searched. Seeking an alternative control, the objective this work was to evaluate the resistance of cowpea genotypes to the attack of Z. subfasciatus. In the first selection of genotypes were evaluated 35 cowpea genotypes, being observed the variables: number of eggs, number of insects emerged and weight loss (%). In this first selection of cowpea were selected 10 genotypes. In the second selection of genotypes, the 10 most resistant from the first selection were used, but with eight repetitions per genotype, besides evaluating the egg viability (%) and instantaneous rate of population growth. The cowpea genotypes showed significant differences for resistance to attack by Z. subfasciatus. The most resistant to Z. subfasciatus were BRS Tracuateua, 31 MNC03-720C-20, 26 MNC00-553D-8-1-2-2 and 37 MNC05-832B-234-5.

“…The adult insect lives for about 4-5 weeks. Species of natural enemies are associated with stored-product insects (Brower et al, 1996) and their potential as biological agents for these pests have been widely studied (Ouedraogo et al, 1996;Donnelly & and Philips, 2001;Amevoin et al, 2007;Iloba et al, 2007). In West Africa (Niger, Burkina Faso, Benin) the solitary ectoparasitoid Dinarmus basalis Rendani (Hymenoptera: Ptermalidae) and its sympatric species Eupelmus vuilleti Crawford and E. orientalis Crawford (Hymenoptera: Eupelmidae) parasitize the larvae and pupae of C. maculatus (F.) and Bruchidius atrolineatus (Pic) (Coleoptera: Bruchidae) which develop inside the seeds of V. unguiculata (Danielle Rojas-Rousse, 2010).…”

Laboratory study was carried out to investigate the efficacy of hymenopteran parasitoids, (Dinarmus basalis and Choetospila elegans) parasitization of Callosobruchus maculatus on cowpea (Vigna unguiculata) seeds in the Department of Crop Science, University of Calabar, Nigeria. Treatments were the inoculation of D. basalis (sole), C. elegans (sole), a mixture of D. basalis and C. elegans into infested cowpea seeds and the control which received no parasitoids. The introduction of parasitoids was repeated at 3 d interval, and all treatments were replicated 3 times. Result indicated that early introduction of the parasitoids caused significantly (P ≤ 0.05) higher mortality of C.maculatus than late introduction. Mix culture of both parasitoids was significantly more efficacious than sole culture. The emergence of each parasitoid and the mortality of C. maculatus in sole culture showed a highly significant (P ≤ 0.01) positive relationship (r = 0.487) between C. maculatus and D. basalis but non-significant (P ≥ 0.05) though positive association (r = 0.289) with C. elegans. A multiple regression analysis between C. maculatus mortality and the emergence of the two parasitoids in mix culture also indicated a highly positive significant (P ≤ 0.01) relationship (R = 0.751, R 2 = 0.564). Pearson Correlation analysis also showed a significant (P ≤ 0.05) positive association (r = 0.464, and 0.401) between C. maculatus mortality and emergence of C. elegans and D. basalis in mix culture, respectively. However, a non significant (P ≥ 0.05) negative relationship (r = -0.336) was observed between the two parasitoids in their emergence in mix culture, but D. basalis contributed more to the mortality of C. maculatus than C. elegans. Data from this study showed that D. basalis and C. elegans have potentials to be deployed as biological control entities in the management of C. maculatus as a part of the integrated pest management strategies of storage pests in the tropics.
