Oviposition decisions in the seed beetle, Callosobruchus maculatus (Coleoptera: Bruchidae): effects of seed size on superparasitism
The seed parasite Callosobruchus maculatus generally disperses eggs uniformly among seeds. We used cowpeas (Vigna unguiculata) of two class sizes (large and small) to test predictions based on a simple resource threshold model that females will distribute eggs among seeds in a manner that maximizes the amount of resources allocated to each offspring. When females were presented with multiple se...

BACKGROUND: Botanicals insecticides has remained the major weapons amongst tropical zones farmers to combat hexapods infestation of stored cowpea seeds in lieu of expensive synthetic chemical insecticides that have toxic effects on our environment. OBJECTIVES: Deterrence of cowpea bruchid oviposition and emergence on seeds treated with Cheese wood, Alstoni...
متن کاملHabitat-related mtDNA polymorphism in the stored-bean pest Callosobruchus chinensis (Coleoptera: Bruchidae).
The genetic diversity of populations of the azuki bean beetle, Callosobruchus chinensis (Linnaeus) from natural, pre-harvest and post-harvest sites, was investigated to understand population structure and gene flow. A 522-bp fragment of the mitochondrial gene COI was sequenced for eight populations of C. chinensisfrom Japan, Korea and Taiwan collected from different habitats. Six haplotypes wer...
متن کاملResistance of Faba Bean and Pea Germplasm to Callosobruchus chinensis (Coleoptera: Bruchidae) and Its Relationship With Quality Components.
In total, 339 faba bean (Vicia faba L.) and 100 pea (Pisum sativum L.) accessions were screened for their ability to resist Callosobruchus chinensis L. in free choice laboratory tests. Four, 15, and 43 faba bean varieties were highly resistant, resistant, and moderately resistant to C. chinensis, respectively. Three immune, three highly resistant, and six resistant accessions were discovered am...
