Abstract - The research was undertaken during 1978 and 1979 at Varanasi, India to understand the impact of weather factors on the light-trap catches of scarabaeid beetles. The biostatistical inference drawn to establish the relationship between scarabaeid catches and weather factors, such as rainfall, relative humidity, temperature and sunshine hours, showed a positive correlation for rainfall and relative humidity, whereas temperature and sunshine hours had respectively a mostly non-significant, and an unclear, contrasting impact on the catches. The join effect of weather variables on the light-trap catches of scarabaeid beetles, as revealed by the Multiple Correlation Coefficient (R), was found to be significant. The Coefficient of Determination (R2) also showed a pronounced impact of weather factors (>40%) on light-trap catches.
