The glutamate-gated chloride channels (GluCls) play essential roles in signal transduction by regulating fast inhibitory synaptic transmission the nervous system of invertebrates. While there is only one GluCl subunit insect, diversity insect GluCls broadened alternative splicing. In present study, three TcGluCl variant genes were cloned from red flour beetle Tribolium castaneum. Analysis chara...
در سال های اخیر ترکیب های با منشأ گیاهی به عنوان عامل کنترل آفات انباری مورد توجه قرار گرفته اند. در این تحقیق، سمّیت تنفسی و تماسی اسانس گیاه پونه (mentha longifolia l.) روی حشره کامل شپشه قرمز آرد (tribolium castaneum herbst) مورد بررسی قرار گرفت. اسانس گیری، با روش تقطیر با آب مقطر و با استفاده از دستگاه اسانس گیر شیشه ای (کلونجر) طی مدت زمان 3 ساعت انجام شد. در سمّیت تنفسی میزان lc50 بعد از 2...
Cytochrome P450 monooxygenase (CYP) is one of the three detoxification metabolic enzymes in insects, and involved metabolism transformation endogenous substances as well activation degradation exogenous compounds. This study aims to reveal molecular mechanism CYP9E2 Tribolium castaneum adapting high-CO2 stress. By predicting sequence function CYP9E2, analyzing temporal spatial expression profil...
As the complexity of animal nervous systems has increased during evolution, developmental control of neuronal connectivity has become increasingly refined. How has functional diversification within related axon guidance molecules contributed to the evolution of nervous systems? To address this question, we explore the evolution of functional diversity within the Roundabout (Robo) family of axon...
In the short-germ beetle Tribolium castaneum, waves of pair-rule gene expression propagate from the posterior end of the embryo towards the anterior and eventually freeze into stable stripes, partitioning the anterior-posterior axis into segments. Similar waves in vertebrates are assumed to arise due to the modulation of a molecular clock by a posterior-to-anterior frequency gradient. However, ...
Dusky-like (Dyl) is associated with the morphogenesis of embryonic denticle, adult sensory bristle and wing hair in Drosophila melanogaster. And whether Dyl involved in insect post-embryonic development and its signal transduction are poorly understood. Here, phylogenetic analysis revealed that dyl displayed one-to-one orthologous relationship among insects. In Tribolium castaneum, dyl is abund...
Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae), the red flour beetle, is an important cosmopolitan pest of stored grains. Commercial traps baited with the synthetic aggregation pheromone 4,8-dimethyldecanal (DMD) are used to monitor T. castaneum population densities in storage facilities. However, trap catches may depend on several intrinsic and extrinsic factors. In this study, we ex...
Acetonic extracts of melon pumpkin, Cucurbita maxima (Duchesne), Sweet Orange, Citrus sinensis (L.) and Sour Orange, Citrus aurantium (L.), were evaluated for insecticidal activity against adults of three stored product pests viz., Sitophilus oryzae (L.), Rhyzopertha dominica (Fabricius) and Tribolium castaneum (Herbst), by filter paper diffusion method (direct contact application) and fumigati...
In animals having internal fertilization, both sexes can potentially influence the post-copulatory processes of sperm transfer, sperm storage and sperm use for fertilization. In this experiment, we investigated whether Tribolium castaneum females can influence male paternity success following consecutive matings with two different males. We compared second male paternity success (P2) between fe...
