The inhibitory potential of purified α amylase inhibitors of sorghum on the digestive enzyme of Tribolium Castaneum, a devastating insect pest of economic importance have been studied. Qualitative and quantitative differences in α amylase of Tribolium Castaneum upon feeding on natural and artificial diets were evident. Natural diets were legumes like Black gram, Pigeon Pea, Red lentil, Cowpea a...
The crude extracts and its fractions of the flower of Tagetes erecta Linn. were tested for insecticidal activity against a stored product insect pest, Tribolium castaneum (Herbst). The chloroform fraction showed highest toxicity against both the larvae and adults of Tribolium castaneum followed by 50 petroleum ether fraction and ethanol extract. The LC values of chloroform fraction against firs...
Threeand 4-week-old Tribolium castaneum (Herbst), the red flour beetle, and Tribolium confusum (du Val), the confused flour beetle, were exposed at five different temperature–relative humidity (r.h.) combinations to a volatile formulation of the insect growth regulator (IGR) hydroprene (called Pointsourcet). Typical effects associated with IGR exposure, such as arrested larval growth, morpholog...
Glutathione S-transferases are important detoxification enzymes involved in insecticide resistance. Sequencing the Tribolium castaneum genome provides an opportunity to investigate the structure, function, and evolution of GSTs on a genome-wide scale. Thirty-six putative cytosolic GSTs and 5 microsomal GSTs have been identified in T. castaneum. Furthermore, 40, 35, 13, 23, and 32 GSTs have been...
Intraspecific competition is believed to drive niche expansion, because otherwise suboptimal resources can provide a refuge from competition for preferred resources. Competitive niche expansion is well supported by empirical observations, experiments, and theory, and is often invoked to explain phenotypic diversification within populations, some forms of speciation, and adaptive radiation. Howe...
The aim of the present study was to introduce an alternative way for insects control through biodegradable plants materials. The different cold water extracts dilutions of Acacia modesta and Glycyrrhiza glabra were tested against Tribolium castaneum. The extracts dilutions of both plants caused mortality of the Tribolium castaneum. ANOVA revealed that dilutions and plants were highly significan...
The iBeetle-Base (http://ibeetle-base.uni-goettingen.de) makes available annotations of RNAi phenotypes, which were gathered in a large scale RNAi screen in the red flour beetle Tribolium castaneum (iBeetle screen). In addition, it provides access to sequence information and links for all Tribolium castaneum genes. The iBeetle-Base contains the annotations of phenotypes of several thousands of ...
Fardisi, Mahsa Ph.D., Purdue University, May 2015. Investigation of dried distillers grains with soluble (DDGS) susceptibility to red flour beetle (Tribolium castaneum (Herbst)) Infestation. Major Professors: Dr. Linda J Mason and Dr. Klein E. Ileleji. Protecting livestock feed from insect infestation is a common challenge that feed facility managers and farmers have to deal with. It becomes an...
A genome's ability to produce two separate sexually dimorphic phenotypes is an intriguing biological mystery. Microarray-based studies of a handful of model systems suggest that much of the mystery can be explained by sex-biased gene expression evolved in response to sexually antagonistic selection. We present the first whole-genome study of sex-biased expression in the red flour beetle, Tribol...
