A field study conducted during 2000-2001 on banana plantation located at Bangalore Rural district revealed that the population of the spiralling whitefly Aleurodicus dispersus Russell declined from 116.85 per 25-cm2 leaf area in March 2000 to 1.10 per 25-cm2 leaf area in December 2001. During the study period, a total of seven natural enemies were observed. The aphelinid parasitoid Encarsia guadeloupae Viggiani was the only major natural enemy encountered on the spiralling whitefly causing 20.70% parasitism in January 2000, which had increased to 95.68% by December 2001. The density of the spiralling whitefly was positively correlated with maximum temperature and negatively correlated with relative humidity and the parasitism by E. guadeloupae. The multiple regression model showed that about 67.94% of the variation in the whitefly density could be accounted for by parasitism only. |
