Assessment of losses by defoliating caterpillars in potato crop



Assessment of losses by defoliating caterpillars in potato crop



Indian Journal of Entomology 46(3): 379-380



The effect of various levels of infestation by the noctuid Heliothis armigera on the extent of damage to potato plants at various stages was studied in field-cage experiments in India. In the 10-day-old crop, losses were 83-100% when 5-25 insects were released on each plant.
