Environmental stresses lower the efficiency of photosynthesis and sometimes cause irreversible damage to plant functions. When spinach thylakoids and Photosystem II membranes were illuminated with excessive visible light (100-1,000 µmol photons m(-1) s(-1)) for 10 min at either 20°C or 30°C, the optimum quantum yield of Photosystem II decreased as the light(More)
The fruit-piercing moth Oraesia excavata (Butler) only attacks ripe as opposed to immature peach fruits. The moth putatively uses volatile emissions from ripe peach fruits as a cue for food orientation. The volatiles emitted by ‘Hakutou’ peach (Prunus persica L.) fruit during maturation were analyzed by headspace solid-phase microextraction followed by gas(More)
Rice fields provide major habitats for lentic aquatic insects including the giant water bug Kirkaldyia (=Lethocerus) deyrolli (Heteroptera: Belostomatidae) in Japan. Previous researchers have emphasized that conserving populations of the frogs, Hyla japonicus and Rana nigromaculata, is very important for preserving K. deyrolli because these frogs were found(More)
