Nutrition regulation of male accessory gland growth and maturation in Tribolium castaneum.

Nutrition Regulation of Male Accessory Gland Growth and Maturation in <em>Tribolium castaneum</em>

Identification of predicted seminal fluid proteins in Tribolium castaneum.

In several insect species, seminal fluid proteins (SFPs) have been demonstrated to be key regulators of male and female fitness through their ability to alter female physiology and behaviour. Tribolium castaneum is an economically important pest species and a model system for sexual selection research, but little is known about SFPs in this insect. To create a foundation for the study of T. cas...

Juvenile hormone regulation of male accessory gland activity in the red flour beetle, Tribolium castaneum

Male accessory gland proteins (Acps) act as key modulators of reproductive success in insects by influencing the female reproductive physiology and behavior. We used custom microarrays and identified 112 genes that were highly expressed in male accessory glands (MAG) in the red flour beetle, Tribolium castaneum. Out of these 112 identified genes, 59 of them contained sequences coding for signal...

Pheromone production by male Tribolium castaneum (Coleoptera: Tenebrionidae) is influenced by diet quality.

Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae), the red flour beetle, is a common cosmopolitan pest exploiting a variety of stored products. We experimentally manipulated diet nutritional quality by using non-nutritive filler to examine how this influenced pheromone production and olfactory attractiveness of T. castaneum adult males. Volatiles released by individual males reared on hi...

Effect of Tribolium castaneum (Coleoptera: Tenebrionidae) nutritional environment, sex, and mating status on response to commercial pheromone traps.

Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae), the red flour beetle, is an important cosmopolitan pest of stored grains. Commercial traps baited with the synthetic aggregation pheromone 4,8-dimethyldecanal (DMD) are used to monitor T. castaneum population densities in storage facilities. However, trap catches may depend on several intrinsic and extrinsic factors. In this study, we ex...
