FROM Artemisia vulgaris AGAINST Diaphorina citri

ABSTRACT
Citrus Vein Phloem Degeneration (CVPD) is a destructive citrus disease caused by
Candidatus Liberibacter asiaticus. of the α-proteobacteria. CVPD are transferred
by their vectors directly into living phloem cells. It is spread by the psyllids vectors
Diaphorina citri. This study aims to examine the effect of various concentration of
mixed combinations kaolin and Artemisia vulgaris essential oil on finding host
behavior D. citri. The research was carried out in the plant protection laboratory
and experimental garden, Faculty of Agriculture, UPN "Veteran" Yogyakarta,
located in Ngropoh, Condongcatur, Kec. Depok, Sleman Regency, Special Region
of Yogyakarta. The research was carried out from February 2023 to July 2023. The
research method was used choice test method, and non-choice test method. The
research method arranged in a completely randomized design. The treatment tested
was a concentration mixture of Artemisia vulgaris essential oil and kaolin. The
concentration mixture of 2% A. vulgaris essential oil and 1.5% kaolin had a
repellency index against D. citri of 0.66 after being tested for 12 hours using a non-
choice test. The repellency of the concentration mixture is based on the odor
emitted, based on the choice test, 90% of D. citri were rejected.
