A survey of Florida fresh citrus packers was conducted in April 2015 to collect data on their packing charges during the 2014/15 season. A total of sixteen packinghouses participated in the survey, seven from the Interior region and nine from the Indian River region. The average of their responses was computed to obtain the estimates presented in this document.

Building a physical barrier around citrus trees or groves can prevent contact between trees and Asian citrus psyllids, the carrier of the pathogen that causes huanglongbing. This new 4-page article is for growers, scientists, and industries that are interested in this approach to protect citrus from huanglongbing. Written by Timothy A. Ebert, Arnold W. Schumann, Laura Waldo, Daniel Stanton, and Philippe Rolshausen, and published by the UF/IFAS Department of Soil and Water Sciences.

Of the many Homoptera pests that infest citrus groves, only a few affect the health and productivity of a tree to a level where control measures are necessary. The first step in controlling any pest is correct identification. Without this, appropriate biological or chemical control measures cannot be selected. Inappropriate pest management tactics may fail to provide control of the target pest and/or disrupt existing natural control of other pests, leading to secondary pest problems. Most of the pests included in this article are under biological control by predators, parasites and pathogens, thus minimizing the need for pesticide applications.

Stephen H. Futch, C. W. McCoy, andC. C. Childers

Control of scale insects in Florida citrus utilizes native and introduced exotic natural enemies, including predators, parasites, and pathogens. Under most conditions, predators and parasites suppress scale pest populations to a level where chemical intervention is unnecessary. In situations where natural enemies do not provide the necessary control, integrated pest management (IPM) is used since it minimizes negative effects on natural enemies. Increases in scale insect populations involve multiple factors including: a) disruption of biological control by weather; b) infestation of areas by scale insects where natural enemies do not exist; and c) disruption of natural enemies by the repeated use of non-selective pesticides.

Stephen H. Futch, C. W. McCoy, andH. N. Nigg

Soil provides a structure for a plant to anchor its roots and is a source of nutrition and water necessary for plant growth. Soil-inhabiting insects also utilize this substrate for part of or for their entire life. Although many insects are dependent on soil for food and shelter, only a few soil-borne insects such as weevils, ants, and termites are detrimental to the citrus tree.

T. A. Ebert, A. W. Schumann, and A. J. Krajewski

Protecting plants by targeting insect vectors of pathogenic organisms requires an intimate understanding of the biology of the insect, the pathogen, and the plant host at a spatial scale relevant to the insect. Observing insect feeding is difficult because insect mouthparts are small, and many insects insert their mouthparts deep inside plants, where we cannot see them. Electropenetrography (EPG) is the only technique that overcomes these problems. Using EPG, we can understand host-insect relationships, pesticide action, and the role of non-hosts. EPG can address ecological questions like "How do insects survive long migrations over regions devoid of known host plants?" It can also address applied questions: "Will the pest feed on my new cultivar?" This light introduction to an underused key technology focuses on a single example insect vector, the Asian citrus psyllid, but EPG has great potential to improve pest management efforts for many crops and insect vectors.

Replacement of dead and diseased trees in Florida citrus groves has always been an important part of citrus production. Today, tree replacement is more important than ever since overhead and production costs are escalating and a full stand of productive trees is essential to maximize production and profits. In more recent times, Huanglongbing (HLB), or citrus greening, has accelerated tree loss rates as well as the ability for growers to bring young citrus trees into production. This revised fact sheet discusses a wide range of techniques for providing young tree care. Many of these should prove useful to Florida citrus growers confronted with the problem of managing resets.
