A census by sweeping in Joetsu (37°06′N, 138°16′E), Niigata Prefecture, Japan, showed that early instar nymphs and adults of the rice leaf bug, Trigonotylus caelestialium (Kirkaldy), occurred on the levees covered with weeds in early November. To determine if nymphs and adults found in late autumn overwinter in the field, bugs collected from the levees in late October to November were confined to a cage along with seedlings of Italian rye grass, Lolium multiflorum, and maintained under natural conditions. No bugs survived until late March of the following year. This indicates the nymphs and adults occurring in late autumn in the field are not likely to overwinter.
