Abstract
The hairy rose beetle. Tropinota squaiida Scop. (Coleoptera: Coccinellidae) is one of the most serious pests of several different crops. Orange crop which infesting by this pest is a delicious and popular fruit in Egypt as well as it has a great nutritional value. Occurrence and distribution of this pest on orange trees (Citrus sinensis) were studied thrOUghout two seasons (2002 and 2003). Results proved the beetles prefered the southern sites of the orange trees than that other three geographical directions. On the other hand, the least numbers of this pest were observed on the western sides of trees. Also, sunny sides of the orange trees harboured more individuals of this pest than shady ones not only in the morning but also at afternoon.
