Summary
Light-trap records on the green rice leafhopper,Nephotettix cincticeps, were dealt with to study its population fluctuations in the Hokuriku district. Crude data were modified for distinguishing years of the low intensity of infestation by the insect from the rest of years. It is then clearly demonstrated that the low intensity of infestation were ordinarily preceded by heavy snowfall, although heavy snowfall could not be regarded as the only factor checking the vigorous multiplication of the populations.
