Resistance to Nilaparvata lugens (Homoptera: Delphacidae) and Nephotettix virescens (Homoptera: Cicadellidae) in ratoon rice
Environmental Entomology 12 (2), 451-454
Abstract: The level of antibiosis to a leafhopper, Nephotettix virescens (Distant), and a planthopper, Nilaparvata lugens (Stal), was evaluated on ratoons of selected varieties. Results indicate that antibiosis levels in the ratoon crop corresponded well with that previously reported for the main crop of the varieties tested. However, levels of antibiosis to the two pests decreased with plant age in some varieties instead of increasing as reported for the first crop. The results suggest that ratoons may be important in providing a suitable host for rice pests between main crops.
