The bugs suck sap from the tender tissues of the spindle leaf and cause necrotic lesions. Seasonal fluctuation in population of the spindle bug studied at three locations revealed that the pest occurred throughout the year. The peak period of the pest abundance was found to vary at different centres. The peak period of occurrence was in January and November at Krishnapuram, in July at Palode and in February at Sullia. High pest population was noted at Krishnapuram and Palode whereas it was quite low at Sullia. Among the weather factors, positive correlation was observed with rainfall and pest population.enArticle
