An analysis of the mode of gene action affecting pupa weight in Tribolium castaneum.

Selection for Pupa Weight in TRIBOLIUM CASTANEUM. I. Parameters in Base Populations.

Sequence variants of CYP345a1 and CYP6a14 gene regions in Tribolium castaneum (Coleoptera: Tenebrionidae) adults treated with the novel characterızed Bolanthus turcicus (Caryophyllaceae) extract

In this study, various doses of plant extracts that obtained from Bolanthus turcicus was applied to an important storage pest Tribolium castaneum adults. Bolanthus turcicus is an endemic species and spreads on the Hasan Mountain above Karkın town (Turkey, Aksaray province). The plant species was collected from June to July with the field study to be carried out in thi...

Expression patterns of cysteine peptidase genes across the Tribolium castaneum life cycle provide clues to biological function.

The red flour beetle, Tribolium castaneum, is a major agricultural pest responsible for considerable loss of stored grain and cereal products worldwide. T. castaneum larvae have a highly compartmentalized gut, with cysteine peptidases mostly in the acidic anterior part of the midgut that are critical to the early stages of food digestion. In previous studies, we described 26 putative cysteine p...

Food Consumption, Feed Efficiency, Metabolic Rate and Utilization of Glucose in Lines of TRIBOLIUM CASTANEUM Selected for 21-Day Pupa Weight.

Food consumption, feed efficiency, metabolic rate and glucose utilization were studied throughout development in one control (1C) and three selected lines (3, 9, 10) of Tribolium castaneum that had been subjected to long term selection for 21-day pupae weight. Growth rate, body composition, cellular growth and the activity of four dehydrogenase enzymes in the same lines have been reported (Medr...

Initial and delayed mortality of late-instar larvae, pupae, and adults of Tribolium castaneum and Tribolium confusum (Coleoptera: Tenebrionidae) exposed at variable temperatures and time intervals

Late-instar larvae, pupae, and adults of Tribolium castaneum (Herbst), the red flour beetle, or Tribolium confusum (DuVal), the confused flour beetle, were exposed for variable durations at 36–54 1C. Beetles were placed in laboratory ovens set at a baseline of 27 1C, the temperature was increased by 0.1 1C per minute until the target temperature was achieved, and beetles were then held for spec...
