Egg-Dumping Behavior Is Not Correlated With Wider Host Acceptance in the Seed Beetle Callosobruchus maculatus (Coleoptera: Chrysomelidae: Bruchinae)
If typical host plants are absent, some herbivorous insects “dump” eggs on unsuitable substrates, even though this can cause complete larval mortality and reduced maternal life span. In the seedbeetleCallosobruchusmaculatus (F.) (Coleoptera:Chrysomelidae: Bruchinae), the tendency to dump eggs varies genetically both within and between populations. A previous study hypothesized that egg-dumping ...
متن کاملPotential of four tropical plant powders as grain protectants against Callosobruchus maculatus (Coleoptera: Chrysomelidae)
Effects of four tropical plant (Aframomum melegueta, Zanthoxylum zanthoxyloides, Piper guineense and Eugenia aromatica) were investigated under tropical laboratory storage conditions for the protection of cowpea seeds against insect infestation. The plant materials were pulverised into fine powder after air drying and admixed with 20 g of cowpea seeds at the ...
متن کاملInsecticidal and repellent activity of typical monoterpenes from plant essential oils against Callosobruchus maculatus (Fabr. 1775)
Synthetic insecticides and repellents have been broadly used worldwide for the control of crop pests and insects acting as vectors of human disease. Despite effectiveness, synthetic insecticides or repellents may cause serious damages to the environment and consequently to humans and animals. The growing biotechnological investigation for alternative insecticides and repellents, particularly of...
متن کاملInbreeding depression in two seed-feeding beetles, Callosobruchus maculatus and Stator limbatus (Coleoptera: Chrysomelidae).
Inbreeding depression is well documented in insects but the degree to which inbreeding depression varies among populations within species, and among traits within populations, is poorly studied in insects other than Drosophila. Inbreeding depression was examined in two long-term laboratory colonies of the seed beetle, Callosobruchus maculatus (Fabricius), which are used frequently as models for...
متن کاملEffect of solar drying on the biological parameters of the cowpea weevil, Callosobruchus maculatus Fab. (Coleoptera-Bruchinae), in Sahelian area
Objective: Callosobruchus maculatus Fab. (Coleoptera: Bruchinae) is a major pest of cowpea seeds (Vigna unguiculata (L.) Walp) in the Sahelian zone. The grain infestation by this insect pest starts in the field at the beginning of fructification of the plant and continues in storage where the damage can be significant if no protective measures are taken. In order to prevent the damage caused by...
