Trials were conducted in Kano, northern Nigeria, during 1996 and 1997 cropping seasons to determine the influence of date of planting and two well-timed insecticides sprays on the incidence of major insect pests namely, the legume pod-borer, Maruca vitrata Fab., legume flower thrips, Megalurothri...

Des essais ont été conduits durant les saisons culturales de 1996 et 1997 à Kano au nord du Nigeria pour déterminer l'influence de la date de plantation et la pulverization de deux insecticides bien connus sur l'incidence des principaux insectes à savoir les boreurs des gousses des légumineuses, ...

Preliminary screening of germplasm from the International Institute of Tropical Agriculture (IITA) showed that a number of cowpea Vigna unguiculata (L). Walp. cultivars have potential for resistance to the flower bud thrips, Megalurothrips sjostedti (Trybom). In an earlier study, 10 cultivars fro...

Alabi, O.Odebiyi, J.Tamo, M.[The relationship between primary metabolites in reproductive structures of cowpea Vigna unguiculata (Fabaceae: Papilionidae) cultivars and field resistance to the flower bud thrips Megalurothrips sjostedti (Thysanoptera: Thripidae)]The relationship between primary metabolites in reproductive structures of cowpea Vigna unguiculata (Fabaceae: Papilionidae) cultivars and field resistance to the flower bud thrips Megalurothrips sjostedti (Thysanoptera: Thripidae)

Upland rice is mostly at risk from soil insect pests, including termites which cause significant yield losses. Studies were conducted at Kasua-Mangani, Kaduna State, Northcentral Nigeria, to evaluate the resistance status of 18 upland NERICA rice varieties to termite attack. The percent plant att...

Les insectes ravageurs constituent une contrainte importante à la production du niébé au Burkina Faso. La présente étude visait à fournir aux producteurs une stratégie de lutte intégrée combinant la résistance variétale vis-à-vis de Clavigralla tomentosicollis Stäl et des pulvérisations d’amandes...

Insect pests are important constraints to cowpea production in central Burkina Faso. The main goal of this study was to provide an IPM strategy based on combination of resistant varieties to the pod sucking bug, and the application of neem seed extract against flower thrips (Megalurothrips sjoste...

Rice and maize intercrop is a common feature of traditional upland rice cultivation in Nigeria. Stemborer larvae cause significant yield loss in rice. The study aimed at identifying stemborer resistant status of upland NERICA rice varieties and evaluating the effectiveness of maize as a trap crop...

Plants damaged by herbivores are known to release odors attracting parasitoids. However, there is currently no information how leguminous plants damaged by the pod borer Maruca vitrata attract the exotic larval parasitoid Therophilus javanus, which was imported into Benin from the putative area o...

Twenty-five villages ofNorthern Beninwere surveyed to identify the constraints of yamchips production, assess the diversity of storage insects on yamchips, and document farmers’ perception of their impacts on the stocks and their traditional management practices. Damages due to storage insects (6...

The legume pod borer, Maruca vitrata, is an endemic insect pest that causes significant yield loss to the cowpea crop in West Africa. The application of population genetic tools is important in the management of insect pests but such data on M. vitrata is lacking. We applied a set of six microsat...

Cowpea is a widely cultivated and major nutritional source of protein for many people that live in West Africa. Annual yields and longevity of grain storage is greatly reduced by feeding damage caused by a complex of insect pests that include the pod sucking bugs, Anoplocnemis curvipes Fabricius ...
