Approximately 50% of total harvested cereal grains are lost during the post-harvest handling and storage, insects main cause for both quantity (reductions in weight) quality. In present study effect microwave radiation was studied on one stored product pest, flour beetle Tribolium castaneum (Hersbt). Adult were obtained from infested products at stores specialized selling Sakaka. Insects with i...

Alternative storage pest control that is more environmentally friendly than the use of synthetic chemical pesticides to botanical from plant essential oils, including clove (Syzygium aromaticum) which contains main compounds eugenol and trans-caryophyllene. To study various mechanisms action oils as insecticides could in silico approach through molecular docking. This aims predict dominant bind...

Dendranthema indicum (L.) Des Moul. is a perennial herb commonly used as a traditional Chinese medicine for a long time. In this work, we took Dendranthema indicum as a target plant and two stored insects which include Tribolium castaneum and Stegobium paniceum adults as target insects. Essential oil obtained from Dendranthema indicum was analyzed by gas chromatography-mass spectrometry (GC-MS)...

N-acetyl transferase (NAT) is responsible to catalyze the transfer of acetyl groups to arylamines from acetyl-CoA. Aralkylamine Nacetyl transferase (AANAT), which belongs to GCN5-related N-acetyl transferase member, is a globular 23-kDa cytosolic protein that forms a reversible regulatory complex with 14-3-3 proteins, AANAT regulates the daily cycle of melatonin biosynthesis in mammals, making ...

In a wheat flour mill, seasonal trends in stored-product insect trap capture, relationships between trap captures inside and outside the mill, and between pheromone trap capture and product infestation, and the impact of fumigation on pest populations, were assessed. Mark-recapture was used to evaluate the potential for movement of insects outside the mill into the mill. For Plodia interpunctel...

The role of Hox genes in the development of insect gnathal appendages has been examined in three insects: the fruitfly, Drosophila melanogaster; the milkweed bug, Oncopeltus fasciatus; and the red flour beetle, Tribolium castaneum. In each of these organisms, the identity of the labium depends on the homeotic genes Sex combs reduced (Scr) and proboscipedia (pb). Loss of pb function in each of t...

When hybrid inviability is an indirect by-product of local adaptation, we expect its degree of severity between pairs of populations to vary and to be sensitive to the environment. While complete reciprocal hybrid inviability is the outcome of the gradual process of local adaptation, it is not representative of the process of accumulation of incompatibility. In the flour beetle, Tribolium casta...

Phosphine resistance in stored-product insects occurs worldwide and is a major challenge to continued effective use of this fumigant. We determined resistance frequencies and levels of resistance in Tribolium castaneum and Plodia interpunctella collected from California almond storage and processing facilities. Discriminating doses of phosphine were established for eggs and larvae of P. interpu...

Beetles (Coleoptera) are the most diverse animal group on earth and interact with numerous symbiotic or pathogenic microbes in their environments. The red flour beetle Tribolium castaneum is a genetically tractable model beetle species and its whole genome sequence has recently been determined. To advance our understanding of the molecular basis of beetle immunity here we analyzed the whole tra...
