Managing stored-product insect pests by heating the ambient air of a food-processing facility to high temperatures (50-60 degrees C), also referred to as heat treatment, is an effective technology that has been used since the early 1900s. The minimum temperature during heat treatment for effective disinfestation is 50 degrees C. The effect of sublethal exposures to 50 degrees C on the reproduct...
The insect growth regulator novaluron (Rimon 10 EC, Makhteshim-Agan Ltd, Israel) is used against many field pests on corn, vegetables, orchards, forests, and cotton plantations. Previously, we studied various effects of novaluron on stored grain pests. Termination in Tribolium castaneum (Herbst) eggs hatching after treating adults with novaluron and following restoration after adult transfer to...
This study determined the efficacy of Beauveria bassiana (Balsamo-Crivelli) Vuillemin (Hypocreales: Cordycipitaceae) alone or combined with diatomaceous earth DEA (a mixture DE + abamectin) against adults and larvae Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae). was evaluated at 50 ppm while fungi 1.6 × 105, 106, 107 conidia/kg wheat). Mortalities were assessed after 7 14 days exposu...
The chemical composition of the essential oil of Etlingera yunnanensis rhizomes and its contact and repellent activities against Tribolium castaneum (Herbst) and Liposcelis bostrychophila (Badonnel) were investigated. The essential oil obtained from E. yunnanensis rhizomes with hydrodistillation was performed by gas chromatography-flame ionization detection and gas chromatography-mass spectrome...
Cytosine DNA methylation is a vital epigenetic regulator of eukaryotic development. Whether this epigenetic modification occurs in Tribolium castaneum has been controversial, its distribution pattern and functions have not been established. Here, using bisulphite sequencing (BS-Seq), we confirmed the existence of DNA methylation and described the methylation profiles of the four life stages of ...
We evaluated knockdown caused by four insecticides: alpha-cypermethrin, chlorfenapyr, pirimiphos-methyl and fipronil against adults of Tribolium confusum Jacquelin Duval, the confused flour beetle and Oryzaephilus surinamensis (L.), the sawtoothed grain beetle. Bioassays were conducted on concrete and metal surfaces. Adults of the tested species were exposed on both surfaces treated with the ab...
Insecticide resistance is an escalating global issue for a wide variety of agriculturally important pests. The genetic basis and biochemical mechanisms of resistance are well characterized in some systems, but little is known about the ecological aspects of insecticide resistance. We therefore designed a laboratory experiment to quantify the progression of phosphine resistance in Tribolium cast...
Tribolium castaneum can survive in extremely dry environments and be one of the major insect pests broken processed grains or other stored dried foods. Additionally, this species has demonstrated resistance to some classes insecticides. The objective work was evaluate nutritional chemical composition T. castaneum, reared on maize flour, compare protein, lipids fatty acids profile, amino mineral...
The identification and analysis of genes controlling segmentation in Drosophila melanogaster has opened the way for understanding similarities and differences in mechanisms of segmentation among the insects. Homologues of Drosophila segmentation genes have been cloned and their expression patterns have been analyzed in a variety of insects, revealing that the patterns of expression of many gene...
