Abstract

Tamarixia radiata (Waterson) (Hymenoptera: Eulophidae) has been identified as a biological control agent of the Asian Citrus Psyllid (ACP), Diaphorina citri, Kuwayama (Hemiptera: Psyllidae). This psyllid has been shown to vector Huanglongbing (HLB), which is a disease that has crippled the Florida citrus industry. Efforts by the California Department of Food and Agriculture (CDFA) have been made to rear and release T. radiata to control the spread of D. citri before the psyllid reaches dangerous population levels in California. In order to adequately study the psyllid and experiment methods to eliminate the spread of the disease, a substantial population of ACP in a controlled environment is essential. A host plant for the rearing of D. citri to feed reared populations of T. radiata is necessary, in which case Murraya koenigii (L.) (Rutaceae), or the Curry Leaf plant, is used. The Curry Leaf plant can support populations of ACP, but only if the plant continuously produces new, green growth which the ACP require to breed and feed on. Different regiments of pruning, Cytokinin application, and fertilizer application were tested to evaluate their efficacy in inducing flush in previously pruned M. koenigii plants. Thereafter, ACP were placed on the plants to observe which regiment produced the most appealing flush for reproduction of the psyllid.
