The influence of four cereals namely, flours of wheat (Triticum aestivum L.), millet (Pennisetum glaucum L.), sorghum (Sorghum bicolor (L.)Moench) and maize (Zea mays L.)on the growth and development of T. castaneum was investigated at ambient tropical laboratory conditions of 30±3 ̊C and relative humidity of 75±5%. The antinutrients, mineral profile and proximate compositions of the four 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...

Hermetic storage is used to protect grain against insect pests, but its utility is not limited to whole grains. We evaluated hermetically-sealed, polyethylene terephthalate (PET) bottles for preserving wheat and maize flour against red flour beetle (RFB, Tribolium castaneum, Herbst) population growth. Flours infested with RFB and kept in sealed PET bottles experienced much less weight loss over...

A field test was conducted whereby adult Tribolium confusum (du Val), the confused flour beetle, were exposed in Petri dishes lined with filter paper and containing 0–2000mg of flour, to a pyrethrin–CO2 aerosol inside an empty warehouse. Applications were made according to label directions, and beetles were exposed to the aerosol for 2 h. After exposure, knockdown was assessed, and beetles were...

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...

The Getty Conservation Institute and the J. Paul Getty Museum have been studying the use of low oxygen atmospheres using nitrogen for pest eradication. Earlier work by Nieves Valentin and Frank Preusser found that a 30-hour exposure to an atmosphere of 0.5% oxygen and 99.5% nitrogen killed all life stages of the fruit fly (Drosophila melanogaster) [1]. In a collaborative project at the Universi...

Red flour beetle (T. castaneum) is a major pest of stored grains and is known for its adaptability to all classes of insecticides. The present study was carried out to determine the insecticidal potential of egg white proteins to manage beetle population. Protein samples obtained through salt fractionation were lyophilized and were used separately and simultaneously in different concentrations ...

Specific IgE to proteins from Tribolium confusum (TC), a flour beetle, was detected in 9/125 sera of subjects exposed to rye and wheat flour. TC RAST was not inhibited by Dermatophagoides pteronyssinus, rye or wheat flour. Immunoblot experiments showed specific binding to three proteins from adult TC or pupae, not present in rye or wheat flour. These findings suggest that TC might act as an occ...

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...

Protein-enriched pea flour is toxic and repellent to three major stored grain pests, the rice weevil, Sitophilus oryzae (L.), the red flour beetle, Tribolium castaneum (Herbst) and rusty grain beetle, Cryptolestes ferrugineus (Stephens). A unique and valuable aspect of the protein-enriched pea flour is that it is not toxic several parasitoids that are associated with two of these insect pests. ...
