Research Project: ASSESSMENT OF A MECHANICAL SAMPLING DEVICE FOR ASIAN CITRUS PSYLLID

Location: Subtropical Insects and Horticulture Research

2011 Annual Report


1a.Objectives (from AD-416)
To evaluate/develop a mechanical drive for sampling Asian citrus psyllid.


1b.Approach (from AD-416)
Pest & Disease Management and ARS will identify research needs relative to validating the effectiveness of the mechanical sampling device and work together to accomplish the research. A sampling unit will be identified for the device (either time of operation or number of trees sampled). Numbers of psyllids captured per sample unit will be determined at multiple locations in different blocks of trees. The effect of the device on fruit drop will be explored. Modifications to the device will be considered in an effort to increase efficiency, stabilize variability and reduce any negative effects associated with fruit drop.


3.Progress Report

This project is related to inhouse objective 3c: Investigate basic biology and ecology of the Asian citrus psyllid and its natural enemies in Florida citrus.

The sampling device has been observed in action four times. Data variables have been identified, and preliminary assessments have been made of the device with respect to methods of operation. Trials were conducted to assess the device with respect to obtaining quantitative estimates of psyllid densities. Evaluations are planned for this fall of the ability of this device to detect psyllids when population levels of the insect are low, in which detection by the device will be compared to detection of conventional tap sampling. Of interest will be the times required to detect psyllids using each method.

Progress was monitored through direct involvement in lab and field activities, research meetings, and discussions with collaborators at U.S. Horticultural Research Laboratory (USHRL) and Animal and Plant Health Insepction Service Plant Protection and Quarantine (APHIS-PPQ), telephone calls and email communications.
