Nuisance Insects of Rearing mass Asian Citrus Psyllid (ACP) Diaphorina citri Under Controlled Conditions

Rearing insects for pest experiment it’s very critical. The condition of rearing such insects impacted the smooth running of research. This condition also happens in the rearing of Asian Citrus Psyllid (ACP), Diaphorina citri. ACP is one of the most dangerous pests of citrus since responsible for the huanglongbing disease vector in citrus. Many researchers, either laboratory or field-based use a D.citri for object experiments. A clear and recent description of the types of insects or arthropods that disturb the rearing ACP is needed, especially in Indonesia. The research was conducted in the greenhouse of Faculty of Agriculture, Gadjah Mada University, from January 2021 to September 2022. The rearing of ACP uses orange jasmine (Muraya paniculata) and citrus (Citrus nobilis). The collected insect and spider preserved in alcohol or pined in insect tray and identify them based on related literature. This study proposed to assess the nuisance insect that infested on rearing of D.citri based on greenhouse conditions.
