Effect of environmental factors on the population dynamics of major sucking pests of brinjal

Abstract

Incidence of whitefly started during 34th SMW, while initial jassid and hadda beetle infestation was observed during 35th SMW. However, peak population of whitefly was observed during 41st SMW, whereas, jassid and hadda beetle population reached its peak level on 42nd and 43rd SMW, respectively. The correlation analysis showed that the whitefly population has significantly positive correlation with maximum temperature. Further, negative significant correlation showed with morning RH, evening RH and rainfall with whitefly population. Correlation analysis of certain abiotic factors with jassid and hadda beetle revealed that the population also showed positive correlation with temperature but negative correlation was found with relative humidity and rainfall. © 2023, Journal of Entomological Research.
