End Date: Nov 29, 2015
Behavioral assays and antennogram (EAG/EAD) methods will be developed for key citrus pests to identify conspecific odors that mediate mate location, recognition or aggregation. Methods for monitoring and control using these compounds will be developed. Host and nonhost compounds will be identified that affect host selection, location or repellency through the use of gas chromatography (GC), GC-EAD, and GC-mass spectroscopy (GC-MS). To increase natural biological control of the Asian citrus psyllid, haplotypes of the parasitoid Tamarixia radiata will be characterized and released as deemed appropriate. Viral pathogens of Asian citrus psyllid and sharpshooter species will be identified by genomic methods and evaluated as management strategies. Existing citrus germplasm will be screened for host plant resistance to Asian citrus psyllids under greenhouse and field conditions. Genes and proteins involved in key biological processes such as salivary sheath formation will be studied to develop novel control strategies that block these processes.
