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

Location: Subtropical Insects and Horticulture Research

2012 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 Objective 3c: Investigate basic biology and ecology of the Asian citrus psyllid and its natural enemies in Florida citrus.

The sampling device was evaluated many times this year. A database of numbers of psyllids captured by the device was compiled and continues to be expanded. The time and expense associated with using the device in citrus is also being evaluated. In addition to characterizing the device as a tool for showing general psyllid population levels in a group of trees, we have expanded this to include assessments of the value of the device for detecting psyllids when psyllids are scarce. The ability of the device to detect adult psyllids is being compared to two other detection methods, visual searchers and tap sampling.
