Abstract
CVPD or greening disease is the most devastating disease on citrus production in lndonesia 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 50 oC and 80 oC of red, white, and non-seed guava shoots to ten adult psyllids of mixed gender were determined in y-tube olfactameter. The result shows that guava shoots has repellent effect to psyllids adult. The effect is reduced as the increase of drying temperature. Highest repellent effect is found from red guava shoots, followed by non-seed guava and white guava.
