Effects of gamma radiation on the reproductive organs in the red flour beetle Tribolium castaneum (Herbst)
Gamma radiation effects on the gonads of Tribolium castaneum were assessed by cytological techniques. Pupal treatments of 15 Gy resulted in the significant reduction of testes and ovaries leading to sterility in males and infecundity in females, respectively. The present findings thus provide an important information for designing a sterile male technique for this storage pest species.
متن کاملEffect of feeding rats on gamma irradiated flour infected with Tribolium confusum
Background: Flour is one of the most important food sources, therefore it must be kept healthy and clean. As a potential pest control modality, we aimed to examine whether flour irradiation is a feasible tool to eradicate Tribolium confusum adults from infected flour considering probable health effects of infested flour consumption. Materials and Methods: unirradiated and irradiated flour were ...
متن کاملFunctional value of elytra under various stresses in the red flour beetle, Tribolium castaneum
Coleoptera (beetles) is a massively successful order of insects, distinguished by their evolutionarily modified forewings called elytra. These structures are often presumed to have been a major driving force for the successful radiation of this taxon, by providing beetles with protection against a variety of harsh environmental factors. However, few studies have directly demonstrated the functi...
متن کاملDietary Effects on Fitness Components at the PGM-1 Locus of TRIBOLIUM CASTANEUM.
The pattern of genetic differentiation among experimental populations of the flour beetle Tribolium castaneum suggested the hypothesis that relative fitness of three genotypes at the PGM-1 locus (or other linked loci) depends directly on diet. This hypothesis was tested by measuring several fitness components (developmental time, survival, fecundity, rate of egg cannibalism) on groups of indivi...
متن کاملLong-term Efficacy of Protein-enriched Pea Flour against Tribolium Castaneum (coleoptera: Tenebrionidae) in Wheat Flour
Long-term efficacy of the protein-enriched flour of pea (Pisum sativum L. var. Bonneville) in its toxicity, progeny reduction and organoleptic properties was evaluated by combining it with wheat flour and testing the admixture against the red flour beetle, Tribolium castaneum (Herbst). The toxicity and progeny-reducing effects of the wheat flour treated with protein-enriched pea flour were stab...
