Abstract

Citrus plants suffer greatly from the Asian citrus psyllid (ACP), Diaphorina citri
Kuwayama. In addition to being a pest, this insect transmits the infectious
bacterial Candidatus Liberibacter asiaticus, the causal agent of Huanglongbing
disease (HLB) or citrus vein phloem degeneration (CVPD). The aims of this study
were the determine the effect of kaolin and neem seed oil extract mixture on the
host finding and the oviposition behavior of ACP. This research was conducted in
October 2022 - September 2023 at the experimental garden of the Faculty of
Agriculture, UPN “Veteran” Yogyakarta, located in Wedomartani, Ngemplak,
Sleman, Yogyakarta. The method used was the choice test and non-choice test
method. The data were analyzed by using analysis of variance (ANOVA) with a
significant level of 5% using a randomized complete block design (RCBD) with
six replications, if there was a significant difference between treatments, it was
further analyzed using the Duncan Multiple Range Test (DMRT). The study
found that neem seed oil and kaolin can be used for distrupting host finding
behavior, however there was not any effect on the variation of neem seed oil and
kaolin concentration. A mixture of kaolin and neem seed oil extract,
N1.5%+K5%, significantly reduced psyllid oviposition
