“…Cowpea plant spacing likewise do not significantly influence M. vitrata infestation (Alghali 1991;Asiwe et al 2005). Intercropping of cowpea with other crops (maize, sorghum, peppers, cassava, pigeonpea, and Sesbania) did not show clear evidence of reduction of M. vitrata infestations (Ezueh and Taylor 1984;Dissemon and Hindorf 1990;Gethi et al 1993;Emeasor and Ezueh 1997;Bottenberg et al 1998;Capo-Chichi et al 2008).…”

The legume pod borer Maruca vitrata Fabricius (Lepidoptera: Crambidae) is a pantropical insect pest of legumes. In West Africa M. vitrata is the most devastating insect pest of cowpea, a food crop providing much-needed, inexpensive protein to farmers and consumers. Various approaches to controlling this pest have been tried, including cultural management, host plant resistance and use of synthetic and botanical pesticides, all with limited success. In this review we present information on the distribution, morphology, molecular characteristics, behavior and host plants of M. vitrata. We give especial attention to innovative management tactics being developed for West Africa, including genetically engineered Bt cowpea, new biopesticides and use of exotic parasitoids. We discuss research needs for enhancing integrated pest management (IPM) for M. vitrata in Africa.

“…The efforts to make available cowpea cultivars with good levels of resistance to one or more insect pests, and provide programmes for their cultivation under minimum insecticide regimes in conjunction with improved cultural practices, should lead to the establishment of effective pest management 134 S.

Research has shown that there are effective insecticides for every insect pest on cowpea; there are cropping patterns that either increase or decrease insect pest populations (Amoako-Atta, 1983;Okeyo-Owuor et al, 1983;Gethi et al, 1993;Ehlers, 1994); damage can be substantially reduced through manipulation of planting dates; and there are cowpea cultivars with resistance to one or more pests. To-date no integrated pest management programme has been developed for cowpea pests in most countries; the reason usually given for this is the inadequacy of information on the various components necessary for the formulation of IPM packages .…”

Cowpea, Vigna unguiculata (L.) Walp., is susceptible to a wide spectrum of insect pests from seedling to harvest as well as in storage. Insecticide use has been the most commonly adopted method for the control of cowpea pests. However, due to the deleterious effects of insecticides on man, livestock and the environment, research over the years has been focused mainly on developing resistant/tolerant cultivars as a vital component in the integrated management of cowpea pests. This approach has, however, recorded varying degrees of success, due in part to the multiple and often overlapping pest complex attacking at different phenological growth stages of the crop.In spite of the progress in the utilisation of insect-resistant cowpea varieties, the use of resistance as a control tactic has by no means been fully realised. There are many important cowpea insect pests for which resistant varieties are not yet available for commercial cultivation. Where resistant varieties are available for a given insect, these varieties may not be widely planted because of their unsuitability to local conditions. In this paper, the status of host plant resistance research in cowpea is reviewed and some novel approaches aimed at solving its seemingly intractable pest problem are proposed, based on the state-of-the-art scientific and crop biotechnological development. The proposed framework for orientation of cowpea resistance research should ensure yield stability and sustainability for the resource-poor, smallscale farmers in Africa.Resume-Le niebe Vigna unguiculata L. (Walp.), est susceptible a une large gamine d'insectes ravageurs qui l'attaquent depuis le semis jusqu'a la recolte aussi bien qu'en emmagasinage. L'utilisation d'insecticides a ete la methode de lutte la plus utilisee contre les ravageurs du niebe. Toutefois, suite a des effets nefastes des insecticides sur l'homme, le betail et l'environnement, la recherche a ete, depuis des annees, principalement centree sur la selection de varietes tolerantes/resistantes comme composante essentielle dans la lutte integree contre les ravageurs du niebe. Cette approche a toutefois connus des degres de succes varies, suite en partie au caractere multiple et souvent imbrique du complexe des ravageurs qui attaquent la plante aux differents stades phenologiques de sa croissance.Malgre le proges de l'utilisation des varietes de niebe resistantes aux insectes, l'usage de la resistance comme tactique de lutte n'a pas du tout ete pleinement realise. II y a beaucoup d'insectes qui sont d'important ravageurs du niebe pour lesquels les varietes resistantes ne sont pas encore disponibles pour la culture commerciale. La ou des varietes resistantes sont disponibles pour un insecte donne, elles peuvent ne pas etre plantees a grande echelle a cause de leur inaptitude a s'accommoder aux conditions locales. Dans cet article, l'etat de la S. OGHIAKHE recherche sur la resistance de la plante hdte est revue et quelques nouvelles approches visant a resoudre le probleme apparemment insoluble du ravageur so...
