Abstract We examined the attraction of adults to six LEDs in red flour beetles, Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae), which is widespread as a stored grain insect. In experiment, bluish green and were more attractive than two UVs, blue, only females. On other hand, no difference was found among males. Next, we investigated relationship between light intensity attractiveness....

The gene Toll (Tl) encodes a maternally supplied interleukin 1 receptor-related transmembrane protein, a key component required to establish dorsoventral polarity in the Drosophila embryo. We have isolated Tl homologs of a primitive dipteran, Clogmia albipunctata, and of the beetle Tribolium castaneum. Tribolium Tl protein (Tl) lacks sequences in the C-terminal portion of the cytoplasmic domain...

The insecticidal activity of juvenile hormone agonists methoprene and pyriproxyfen, and the ecdysone agonists RH-5849 and tebufenozide was evaluated against susceptible and actellic-resistant strains of Tribolium castaneum and susceptible strains of Rhyzopertha dominica and Sitophilus oryzae. Concentrations ranging from 0.1 to 20 ppm of the analogues were mixed in the food medium to which the t...

Bu çalışmada bitkisel bir insektisit olan Azadirachtin, bunun yanında entomopatojen fungus Verticillium lecani, Metarhizium anisopliae, Beauveria bassiana, Paecilomyces fumosoreus etken maddeli ticari preparatların Tribolium castaneum üzerindeki etkileri araştırılmıştır. Denemelerde biyolojik insektisitlerin önerilen dozları uygulanmış, 1, 3, 5, 7, 14 ve 21 gün sonra canlı-ölü bireyler sayılmış...
