REPRODUCTIVE COMPENSATION IN TRIBOLIUM CASTANEUM

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.

Female polyandry affects their sons' reproductive success in the red flour beetle Tribolium castaneum.

A potential benefit to females mating with multiple males is the increased probability that their sons will inherit traits enhancing their pre- or post-mating ability to obtain fertilizations. We allowed red flour beetle (Tribolium castaneum) females to mate on three consecutive days either repeatedly to the same male or to three different males. This procedure was carried out in 20 replicate l...

Embryonic patterning mutants of Tribolium castaneum.

The identification and analysis of genes controlling segmentation in Drosophila melanogaster has opened the way for understanding similarities and differences in mechanisms of segmentation among the insects. Homologues of Drosophila segmentation genes have been cloned and their expression patterns have been analyzed in a variety of insects, revealing that the patterns of expression of many gene...

Expanding the genetic toolkit of Tribolium castaneum

Close linkage of eye color genes in Tribolium castaneum.

N the course of linkage studies involving several new mutations affecting eye I pigmentation in the flour beetle, Tribolium castaneum, it became apparent that while being nonallelic to each other and to previously reported eye mutants they were not randomly distributed in the genome. In fact, of the nine eye mutant loci thus far reported, six occur as colsely linked members of three gene pairs....
