Effect of weather conditions on the incidence of the rice gall midge, Pachydiplosis oryzae



Effect of weather conditions on the incidence of the rice gall midge, Pachydiplosis oryzae



Rice Entomology Newsletter (4): 33-34



In field-plot studies in Kerala, India, during 1967-68 and 1971-72 on the effect of weather conditions on the incidence of Orseolia oryzae (Wood-Mason) (Pachydiplosis oryzae) on rice crops, the percentage of silver shoots 45 days after planting showed that there was a strong positive correlation between infestation and mean rainfall, and a strong negative correlation between infestation and mean maximum temperature.
