The effect of four host plant species of the herbivore Maruca vitrata Fabricius (Lepidoptera: Crambidae) on development time, longevity, fecundity and sex ratio of the parasitoid Apanteles taragamae Viereck (Hymenoptera: Braconidae) was investigated under laboratory conditions. The larvae were pa...

The incidence of the key insect pest of cowpea (Vigna unguiculata L. Walp), the legume pod borer Maruca vitrata F., was investigated with light trap in the Sudano-Sahelian zone of Niger in 2014 and 2015. The results revealed that the first larvae appeared in August (0.03 ± 0.03 to 2.48 ± 0.32 lar...

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, ...

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...

Apanteles taragamae Viereck is a larval parasitoid introduced in Benin for classical biological control of the cowpea pod borer Maruca vitrata Fabricius. In the laboratory, we evaluated the effects of A. taragamae on non-target herbivore species, and on another parasitoid of M. vitrata, i.e. the ...

The bioactivity of Alstonia boonei De Wild leaf alkaloid was tested under laboratory bioassay against the legume pod borer, Maruca vitrata Fabricius. The alkaloid was incorporated into standard M. vitrata artificial diet at five doses [0.00 % (Control), 0.02 %, 0.05 %, 0.10 % and 0.20 %], and fed...

The legume pod‐borer Maruca vitrata (Fabricius), [Lepidoptera: Pyralidae] is a major constraint restricting increased cowpea production in tropical Africa and Asia. Since lectins are known to have insecticidal properties against several pests, a survey was undertaken to screen for the effects of ...
