Abstract
Citrus production in Indonesia and the world is facing a serious problem by CVPD
attacks. Diaphorina citri is the vector of the disease. Guava leave extract is able to be proposed
as prospective control means for the vector. Investigation was conducted to identify the repellent
effect of guava leaves to adult of D. citri and the attractiveness to its predator, Menochilus
sexmaculatus. Repellent effect of grinded dried of upper, middle, bottom shoot of non-seed,
white, and red guava shoots to D. citri and M. sexmaculatus were determined in Y-tube
olfactometer. The result showed that repellence effect to D. citri was on guava shoots odor
sources. Repellence effect was highest on white guava shoots, followed by non-seed guava and
red guava. Repellent effect was 80.7%, 72.7%, and 70.0% respectively. However they did not
have any repellent effect to M. sexmaculatus. Guava shoots had the attractiveness effect to M.
sexmaculatus adult. The effect was higher on upper, middle, and bottom shoot of red guava, and
white guava, and middle shoot of non-seed guava than on upper shoot of citrus. Exception
phenomenon was found on upper and bottom shoot of non-seed guava. The attractiveness on
those shoots was lower than on citrus leaves. It was able to use guava shoots to repel D. citri and
to attract M. sexmaculatus adult as a part of control means of D. citri vector of CVPD disease.
