Abstract

The seasonal abundance in the population of Nephantis serinopa was estimated on 50 young infested plants in the field during the different months for two years by direct count of the larval population at monthly intervals. The two peak periods of infestation were in June and April and the lowest .in January. The abundance of the pest was directly correlated with relative humidity and nearly inversely proportional to temperature and sunshine. Rainfall also indirectly influences the decline in population.
