Abstract
The Asian citrus psyllid ACP is an important pest because it transmits a bacterium putatively responsible for huanglongbing a devastating citrus disease Research on ACP chemical ecology is of interest with respect to identifying attractants and repellents for managing the psyllid We report on an assay for investigating ACP attraction to the foliar odor of one of its host plants orange jasmine Murraya exotica L Flush shoots from this plant were placed into 25 dram vials covered with a paper wrapper a lid with a small entrance hole was snapped onto each vial the vials were placed into a small cage adult ACP were released into the cage and the location of the adults was determined 24 h later A positive response required an adult to find and enter a vial When single males or females were released they were attracted into vials with flush 64 of the time At release rates of 25 50 or 100 adults with 30 repetitions for each rate relatively large mean percentages of adults ca 83 positively responded to flush shoots ACP can escape from the assay vial and will do so if flush is not present Working with ACP in empty vials fluoropolymer resin applied to the inside of vials reduced escapes but did not eliminate them An entrapment funnel for reducing escapes was tested but it reduced ACP response rates A good method of preventing escapes remains to be developed When two vials of flush were placed in the assay cage and one was treated with a candidate repellent only 8 of adults settled in the vial with the repellentThe authors thank Patrick Legler Angel G RiveraColón and Mamoudou Sétamou for their contributions This article reports the results of research only Mention of a trademark or proprietary product is solely for the purpose of providing specific information and does not constitute a guarantee or warranty of the product by the US Department of Agriculture and does not imply its approval to the exclusion of other products that may also be suitable USDA is an equal opportunity provider and employer
