摘要

The present investigation was carried out in Samastipur district in Bihar. The study on population dynamics of Eoeurysa flavocapitata was conducted at Sugarcane Research Institute, Rajendra Prasad Central Agricultural University, Pusa, Samastipur, Bihar. During the survey, maximum infestation of the bug was found at Pusa. The infestation resulted in stunting of the affected plant and wilting of the leaves, and chlorosis was observed in the leaves. The leaves were covered in sooty mold. Also, a mysterious waxy substance was deposited at the center of the sooty mold infestation. The population dynamics of the bug was studied for a period of two years, i.e. from 2021–23, and the population of E. flavocapitata was correlated with the weather parameter. During 2021–22 cropping period, the infestation of the bug was noticed from 34th Standard Meteorological Week (SMW). The peak population was observed on 4th SMW with 20.9 nymphs and adult/plant. The maximum (− 0.79) and minimum temperature (− 0.77) was significantly and negatively correlated with the population of the bug. In the subsequent cropping year, i.e. 2022–23, the bug started appearing from 37th SMW and reached its peak during 2nd SMW with mean population of 21.2 nymphs and adults/plant. The correlation studies showed that maximum and minimum temperature was significantly and negatively correlated with the mean population of the bug. The biochemical analysis of the mysterious waxy deposit at the center of the sooty mold infestation showed that it was chemically 5.518% carbohydrate, 1.048% protein and 17% lipid.
