Abstract
CVPD or greening disease is the most devastating disease on citrus production in Indonesia and in the world. It is vectored by Asian citrus psyllid (Diaphorina citri). Guava leave extract is a prospective control means for reducing psyllid population. Research was conducted to investigate the repellent effect of guava shoots to psyllids. Repellent effect of grinded dried upper shoot (leaf number 1 and 2 from the top) of 50oC and 80oC of red, white, and non-seed guava shoots to ten adult psyllids of mixed gender were determined in Y-tube olfactometer. The result shows that guava shoots has repellence effect to psyllids adult. The effect is reduced as the increase of drying temperature. Highest repellence effect is found from red guava shoots, followed by non-seed guava and white guava. It is suggested that the highest repellent properties is in red guava shoots and the ability will increase in line with the increasing of drying temperature. However the effect of extraction temperature on psyllids attractiveness should be proved further. Keywords: Diaphorina citri, guava, CVPD, disease vector, drying temperature
