    Abstract

    The impact of CVPD infected Siem citrus on the behavior of Diaphorina citri was studied base on cohorts in the laboratory and observation in the citrus plantation. Two cohorts were cultured on CVPD infected and uninfected citrus, each cohort consisted of 150 nymphs of fourth instar. Observation was conducted on 15 vegetative twigs and 30 generative twigs. The existence of the psyllid on citrus canopies was not significantly affected by CVPD. Eggs were only found on shoots. Nymphs were found on shoots, young leaves, and majority found significantly on developed shoots and petioles. Adults were found on shoots, developed shoots, young leaves, and majority found significantly on old leaves. Fruits, flowers, and flower buds were not attacked by the psyllids. Daily-activity pattern of the psyllid was not significantly affected by CVPD. At noon, the adults moved from upper surface to the petioles and lower surface of the leaves.
