abstract due to economical importance of stored product pests and resistance to conventional insecticides, it is necessary to use novel and suitable compounds in control programs. therefore, we evaluated the toxicity of spinosad to three important storage insect, red flour beetle, tribolium castaneum (herbst), rice weevil, sitophilus oryzae (l.), sawtoothed grain beetle oryzaephilus surinamensi...

While developing radio frequency heat treatments for dried fruits and nuts, we used a heating block system developed by Washington State University to identify the most heat-tolerant life stage of red flour beetle, Tribolium castaneum (Herbst), and to determine its thermal death kinetics. Using a heating rate of 15 degrees C/min to approximate the rapid heating of radio frequency treatments, th...

Beetles are reckoned to make up about one quarter of animal species. Now, the first genome of a beetle--the red flour beetle Tribolium castaneum, a pest and developmental model system alike--has been sequenced.

A series of experiments was conducted to determine the effect of a flour food source on survival of red flour beetle, Tribolium castaneum (Herbst), and confused flour beetle, Tribolium confusum (DuVal), exposed to the labeled rate (0.5 mg/cm2) of Protect-It, a marine formulation of diatomaceous earth. Beetles were exposed at 27 degrees C, and 40, 57, and 75% RH in 62-cm2 petri dishes. When beet...

Cannibalism is a very important factor regulating population dynamics of the red flour beetle. After several days of feeding, the flour becomes conditioned by the beetles, which can affect rates of cannibalism. Flour conditioning is caused by an accumulation of feces, pheromones, and ethylquinone, which is a repellent produced by the beetles. We determined the effect of five different levels o...

The insecticidal pyrazole ethiprole, applied at rates of 7.5 and 10.0 ppm either alone or in combination treatments with deltamethrin, piperonyl butoxide, and chlorpyrifos-methyl, was evaluated as a protectant of stored wheat and stored corn. The commodities were treated with six treatment combinations, including an untreated control, and held for 6 mo at 22, 27, or 32 degrees C and 57% RH. Bio...

The experiment was conducted to evaluate the effect of some containers, chemicals and indigenous materials for protection of wheat seed in storage at the Entomology Laboratory of Sher-e-Bangla Agricultural University (SAU), Dhaka. Wheat seeds were stored in four types of containers (Tin kouta, earthen pot, plastic container and gunny bag) with two types of chemicals (Naphthalene and camphor) an...

Experiments were carried out to evaluate the toxicity of six botanicals, Bazna (Zanthoxylum rhetsa), Ghora-neem (Melia sempervirens), Hijal (Barringtonia acutangula), Karanja (Pongamia pinnata), Mahogoni (Swietenia mahagoni) and Neem (Azadirachta indica) against red flour beetle, Tribolium castaneum Herbst. Leaf and seed extracts were prepared by using acetone, methanol and water as solvents. T...

The relationship between number of holes in a grain probe trap body and capture of stored-grain pests was determined in laboratory tests using adults of the rice weevil, Sitophilus oryzae (L.), the sawtoothed grain beetle, Oryzaephilus surinamensis (L.), and the red flour beetle, Tribolium castaneum (Herbst). Polyvinylchloride (PVC) probe bodies were attached to electronic sensor heads, and ins...
