Characterization of cowpea genotype resistance to Callosobruchus maculatus
The objective of this work was to characterize the resistance of 50 cowpea (Vigna unguiculata) genotypes to Callosobruchus maculatus. A completely randomized design with five replicates per treatment (genotype) was used. No‐choice tests were performed using the 50 cowpea genotypes to evaluate the preference for oviposition and the development of the weevil. The genotypes IT85 F‐2687, MN05‐841 B...
متن کاملCopulation, genital damage and early death in Callosobruchus maculatus.
Antagonistic sexual coevolution stems from the notion that male and female interests over reproduction are in conflict. Such conflicts appear to be particularly obvious when male genital armature inflicts damage to the female reproductive tract resulting in reduced female longevity. However, studies of mating frequency, genital damage and female longevity are difficult to interpret because fema...
متن کاملWhy Do Female Callosobruchus maculatus Kick Their Mates?
Sexual conflict is now recognised as an important driver of sexual trait evolution. However, due to their variable outcomes and effects on other fitness components, the detection of sexual conflicts on individual traits can be complicated. This difficulty is exemplified in the beetle Callosobruchus maculatus, where longer matings increase the size of nutritious ejaculates but simultaneously red...

An investigation was made to study the efficacy of dosage and time of administration in maternal vaccination. Mothers of nile tilapia were vaccinated by intraperitoneal injection with adjuvant-heat killed Streptococcus iniae at one and two weeks after spawning at the dosages of 0,2 ml/kg and 0,4 ml/kg body weight. Unvaccinated mothers were used as control. Agglutinating antibody titers in the b...
متن کاملOviposition 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...
