Screen of Bacillus thuringiensis toxins for transgenic rice to control Sesamia inferens and Chilo suppressalis.
Transgenic rice to control stem borer damage is under development in China. To assess the potential of Bacillus thuringiensis (Bt) transgenes in stem borer control, the toxicity of five Bt protoxins (Cry1Aa, Cry1Ab, Cry1Ac, Cry1Ba and Cry1Ca) against two rice stem borers, Sesamia inferens (pink stem borer) and Chilo suppressalis (striped stem borer), was evaluated in the laboratory by feeding n...
متن کاملevaluation of rice stem borer's damage chilo suppressalis walker (lepidoptera: pyralidae) on different rice varieties
in order to evaluation of rice stem borer's damage (chilo suppressalis walker), on rice cultivars an experiment was carried out by two factors, (three cultivars and five spraying times), in completed randomized block design an factorial sampling was conducted on the hills infested to deadhearts (d.h), whiteheads (w.h) and yield loss. five hills were randomly selected from each plot and...
متن کاملeffective qualitative traits in resistance mechanisms of rice varieties to stem borer (chilo suppressalis (walker)
the use of resistant cultivars remains one of the most reliable methods to manage the pests. in this study the mechanism of resistance in 10 lines of rice for 3 kinds of resistance (antixenoses, antibioses and tolerance) was studied. the egg set of striped stem borer on the leaf of considered lines for antixenoses and larva weight mean and survival percentage of larva were evaluated for antibio...
متن کاملCharacterization of a β-adrenergic-like octopamine receptor from the rice stem borer (Chilo suppressalis).
Octopamine, the invertebrate counterpart of adrenaline and noradrenaline, plays a key role in regulation of many physiological and behavioral processes in insects. It modulates these functions through binding to specific octopamine receptors, which are typical rhodopsin-like G-protein coupled receptors. A cDNA encoding a seven-transmembrane receptor was cloned from the nerve cord of the rice st...
متن کاملDopamine modulates hemocyte phagocytosis via a D1-like receptor in the rice stem borer, Chilo suppressalis
Dopamine (DA) is a signal moiety bridging the nervous and immune systems. DA dysregulation is linked to serious human diseases, including addiction, schizophrenia, and Parkinson's disease. However, DA actions in the immune system remain incompletely understood. In this study, we found that DA modulates insect hemocyte phagocytosis using hemocytes prepared from the rice stem borer (RSB), Chilo s...
