Interpretive Summary:

Technical Abstract: Decision-making in knowledge-based pest management depends upon sampling methods that provide reliable information on pest densities and distributions. Practical sampling methodology must balance sample precision with simple and cost-effective collection techniques. Four methods are currently being evaluated in citrus orchards as part of our effort to develop a sampling program for glassy-winged sharpshooter (GWSS). These include both hand (bucket and beat net) and gasoline-powered (D-Vac and A-Vac) samplers. In addition, yellow-sticky traps have been used simultaneously to determine the level of correlation between the foliage samplers and commonly used yellow-sticky traps. Data sets for each device will be analyzed for mean-variance relationships according to Taylor's power law and sample-size estimates generated according to fixed levels of precision. Ultimately, sequential and binomial sampling plans will be developed for the precise estimation or classification of population density of GWSS for research and pest management application.
