Abstract

Dosage–mortality responses of F1 progeny of treated rice weevils, Sitophilus oryzae, indicated that the weevil is highly tolerant to R-20458. However, the ability of the insect growth regulator (IGR) to suppress F2 progeny production, demonstrated that R-20458 could be used as a protectant for grains.

Résumé

Les résponses posoloque-mortuaire de la progéniture F1 des charançons du riz traîtés, Sitophilus oryzae, ont indique que charançon est très tolérant pour R-02458. Toutefois, la capacité du régulateur de la grosseur d'um insecta (IGR) pour supprimer la production de la progéniture F2, a démonstré que R-20458 pour ait être utilisé pour protéger des grains.
