Abstract
Citrus production in Indonesia and a part of the world facing greening or CVPD disease
is the disease that has the most devastating impact. Diaphorina citri plays an important
role as a pathogen main vector. Guava leave raise as a potential control means to reduce
D. citri population. The investigation was conducted to determine the response of D. citri
to various guava shoots. Responses to ground dried upper shoots of 50oC and 80oC of
white, non-seed, and red guava shoots to ten mixed genders of adult psyllids were
investigated in a Y-tube olfactometer. As the result, D. citri adults refused to move into
guava shoots odors sources. The number of D. citri moved to extract the source of upper
of non-seed and red guava shoots extract is 3.80±0.31 and 2.53±0.22 respectively. D. citri
population move is 5.47±0.22 and 2.60±0.13 for white guava and red guava odor sources
respectively. The responses decreased as the increase in drying temperature. The lowest
response was found from red guava, followed by non-seed guava in the middle level, and
white guava shoots as the highest. It is suggested that shoots properties of red guava have
the highest potency for reducing the D. citri population. However, properties of red guava
upper shoot still have an attractive effect on M. sexmaculatus, a predator of D. citri.
