Sorgum merupakan sumber pangan alternatif setelah beras karena memiliki keunggulan komparatif terhadap serealia lainnya. mempunyai kandungan karbohidrat dan protein yang tinggi dibandingkan dengan beras. Kerusakan pascapanen sorgum paling banyak terjadi selama proses penyimpanan adanya serangan hama Sitophilus oryzae. Penelitian bertujuan untuk mempelajari kerusakan berdasarkan perbedaan kepada...

Plant secondary metabolites play an important role in plant-insect interactions and therefore such compounds may have insecticidal or biological activity against insects. Fumigant toxicity of essential oils of leaves and fruits from oriental arborvitae (Platycladus orientalis [L.] Franco) (Cupressaceae) was investigated against adults of cowpea weevil (Callosobruchus maculatus Fab.), rice weevi...

The insecticidal activities of methanolic extracts two weedy plants leaves Bidens pilosa L. and Rumex dentatus at three different concentrations 3, 5 7% were tested against stored grain pests, Rice weevil Sitophilus oryzae Saw-toothed beetle Oryzaephilus surinamensis L., Bean Acanthoscelides obtectus Say, compared to Neem oil as a commercial product the same for exposure periods

To find a new and safe alternative to conventional insecticides, we evaluated the fumigant toxicity of eight Lamiaceae essential oils and their constituents against the adult rice weevil Sitophilus oryzae. Of the eight species tested, hyssop (Hyssopus offcinalis), majoram (Origanum majorana), and Thymus zygis essential oils showed strong fumigant toxicity against S. oryzae adults at 25 mg/L air...

Spinosad, a reduced-risk commercial insecticide derived from a bacterial fermentation product, possesses both contact and oral toxicities against insects. Contact toxicity of spinosad to adults of Rhyzopertha dominica (F), Sitophilus oryzae (L), and Tribolium castaneum (Herbst) was evaluated by exposure for 24 or 48 h to treated glass Petri dishes. Adults were exposed to different deposits (0.0...

Many insects developing on nutritionally unbalanced diets have evolved symbiotic associations with vertically transmitted intracellular bacteria (endosymbionts) that provide them with metabolic components, thereby improving the host's abilities to thrive on such poor ecological niches. While host-endosymbiont coevolutionary constraints are known to entail massive genomic changes in the microbia...

Temperature gradients were set at the opposite sides of grain storage: 25°C-30°C, 20°C-30°C, 20°C-35°C, 30°C-30°C. The migration and distribution imago Sitophilus oryzae, Rhizopertha dominica Tribolium castaneum in storage observed. results showed significant differences that trends within a certain temperature gradient (p < 0.05). is 25°C-30°C. tends to gather 30°C side area storage, while ...
