Abstract
Seedling screening and survival and population growth studies on 30-day-old plants indicated similar degrees of susceptibility on Taichung Native 1 (TN1) and Triveni rice to Nilaparvata lugens (Homoptera: Dilphacidae). However, studies in the screenhouse and field indicated that at both the vegetative and mature stage, Triveni possesses tolerance to insect damage, expressed as the ability to survive and produce a higher percentage of productive tillers than TN1 at similar N. lugens populations. Yield reduction caused by feeding of N. lugens was ca. 40% when infested with 400 N. lugens on 35, 50, or 75 day-old plants, whereas it was almost 100% on TN1 at the same ages. Photosynthetic activity of seedling-stage Triveni was less affected than that of TN1 when severely damaged by the feeding of N. lugens .
