In our screening program for new agrochemicals from Chinese medicinal herbs, Murraya exotica was found to possess insecticidal activity against the maize weevil, Sitophilus zeamais and red flour beetle, Tribolium castaneum. The essential oil of aerial parts of M. exotica was obtained by hydrodistillation and investigated by GC and GC-MS. The main components of M. exotica essential oil were spat...

Due to the importance of insects present in storages, which cause a lot damage stored materials (cereals, seeds, dates and other materials), current study was proposed determine species spread Iraq. It showed 31 belonging 16 genera under eight families two orders. The specimens were collected from several storage spaces at regions Tribolium castaneum (Herbst, 1797) most abundant population comp...

Insect development has contributed significantly to our understanding of metazoan development. However, most information has been obtained by analyzing a single species, the fruit fly Drosophila melanogaster. Embryonic development of the red flour beetle Tribolium castaneum differs fundamentally from that of Drosophila in aspects suchasshort-germdevelopment, embryonic legdevelopment, extensive ...

The present study was conducted to evaluate the efficiency and effectiveness of some plant extracts Helianthus annuus L., Sesbania sesban Olea europea concentrations 100, 500, 1000, 5000 ppm. effect Nd: YAG laser with wavelength of( 1064nm) different energies which at (10,15 20) within (5 pulses/sec) destruction Tribolium castaneum, found results according used, time period during treatment. Tr...

This research assessed the fumigant activity of essential oil from Piper sancti-felicis Trel and five its components on Tribolium castaneum (Herbst) biological model. Hydrodistillation was used for extraction oil, with separation identification compounds through gas chromatography coupled to mass spectrometry (GC-MS). The evaluated dispersion T. castaneum. majority found in EO were b-nerolidol ...

The study dealt with the effect of alcoholic extract Sesbania sesban seeds and growth regulator Applaud in controlling full phase red flour beetle Tribolium castaneum, as concentrations used for were 0.5, 1.0, 1.5, 2.0%, lowest killing rate was 6.6% at a concentration 0.5% And after 48 hours treatment, while highest reached 93.5% 2.0% treatment compared control sample which no occurred. As beet...

The antenna was the first arthropod ventral appendage to evolve non-leg identity. Models of antennal evolution have been based on comparisons of antennal and leg identity specification mechanisms in Drosophila melanogaster, a species in which appendages develop from highly derived imaginal discs during the larval period. We test for conservation of the Drosophila antennal identity specification...

Females of many animal species are polyandrous, and there is evidence that they can control pre- and post-mating events. There has been a growing interest in consequences of polyandry for male and female reproductive success and offspring fitness, and its evolutionary significance. In several taxa, females exhibit mate choice both before and after mating and can influence the paternity of their...
