Current strategies to control insect pest problems in cowpea include, on the preventive side, host plant resistance and conservation biological control. Because very often these management options alone cannot provide adequate control, curative measures need to be taken, which include augmentativ...
The Natural Resources Institute (NRI) and the International Institute of Tropical Agriculture (IITA) are collaborating to develop sex pheromone traps as monitoring tools for Maruca vitrata. The principal component of the pheromone is (E, E)-10, 12-hexadecadienal. Our trapping experiments in cowpe...
The functional response and some predation parameters of the predators Alloeocranum biannulipes Montrouzier & Signoret (Hemiptera: Reduviidea) and Teretrius nigrescens Lewis (Coleoptera: Histeridae) were evaluated at five different densities of larvae and pupae of Dinoderus porcellus Lesne (Coleo...
Maruca vitrata Fabricius (Lepidoptera: Crambidae) is a polyphagous insect pest that feeds on a variety of leguminous plantsin the tropics and subtropics. The contribution of host-associated genetic variation on population structure wasinvestigated using analysis of mitochondrial cytochrome oxidas...
In previous work successful trapping of the legume podborer, Maruca vitrata Fabricius (Lepidoptera: Pyralidae), was accomplished using a synthetic pheromone blend consisting of (E,E)-10,12-hexadecadienal, (E,E)-10,12-hexadecadienol, and (E)-10-hexadecenal in a 100 : 5 : 5 ratio. In the present wo...
Inventory of insects associated with Jatropha curcas L. (Euphorbiaceae) was conducted from June 2011 to May 2012 at 5 sites in southern and central Benin. Thirty-two major insect pests and 14 natural enemies, including 6 parasitoids and 8 predators, were recorded. The most important phytophagous ...
The insecticidal activity of Maruca vitrata (F.) multi-nucleopolyhedrovirus ( Mavi MNPV) combined with oil from neem, Azadirachta indica Juss and Jatropha curcas L. (Euphorbiaceae) was studied under labo- ratory and fi eld conditions against three key insect pests of cowpea, Vigna unguiculata (L....
Many countries have understood that an alternative is needed to the problems of depletion of fossil fuels. Emphasis is therefore put on biofuel-producing crops. One of the most important biofuel-producing plants in tropical is Jatropha curcas L. Several biotic and abiotic constraints limit J. cur...
Helicoverpa armigera is an indigenous species in Africa and has been reported in the destruction of several crops in Benin. Management of H. armigera pest is mainly focused on the use of synthetic pyrethroids, which may contribute to resistance selection. This study aimed to screen the susceptibi...
