ABSTRACT

The influence of environmental factors including temperature and relative humidity was observed on thrips feeding on Rose, Rloss indica Var. Iceberg, ( Rosaceae) planted at the main campus of University of Arid Agriculture Rawalpindi. The results revealed that there was a negative correlation between the population density and temperature, which meant that the number of thrips decreased with increase in temperature and positive correlation existed between the population density of thrips and relative humidity meaning increase in thrips population with increase in relative humidity level. The studies concluded that environmental factors play very significant role in regulating the population of thrips attacking the flowers of this important plant (the rose).
