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...

Background: Maternal RNAs play a critical role in early development. Variation in the diversity and levels of maternally derived gene transcripts may be central to the origin of phenotypic novelty – a longstanding problem in evolution and development. By studying maternal transcriptomes within and between divergent species, a better understanding of the evolutionary forces acting on maternal RN...

This study was conducted to characterize farmers' post-harvest conservation practices and identify the different storage structures, main pests of cereals in stock, as well mode application insecticides protect seeds against infestations. To these practices, we have prepared a questionnaire answering characteristics population three provinces. The grain structures our region vary depending on l...
