In October 1984, the honey bee tracheal mite, Acarapis woodi (Rennie), was found in Florida. Although it was first described by Rennie in 1921, the mite was not found in the United States until 1984. Rennie described the mite from bees on the Isle of Wight and associated it with the "Isle of Wight" disease. Symptoms of this infestation were described as "bees crawling about unable to fly, and with wings disjointed; dwindling and mortality of colonies have been said to occur rapidly with colonies dying within a month." It was later shown that the tracheal mite was not the cause of the "Isle of Wight" disease (Bailey 1964), and later reports (Bailey 1968, Morse 1978) indicate that A. woodi is not as serious a pest of honey bees as previously thought. In combination with other adverse conditions, however, heavy mite infestations may cause a reduction in bee activity. This document is EENY-172 (originally published as DPI Entomology Circular 267), one of the Featured Creatures series of the Entomology and Nematology Department, Cooperative Extension Service, Institute of Food and Agricultural Sciences, University of Florida.

AbstractWe evaluated the resistance to tracheal mites, Acarapis woodi (Rennie) (Acari: Tarsonemidae), of colonies of honey bees, Apis mellifera L. (Hymenoptera: Apidae), headed by daughters of three queens from each of three honey bee stocks: (i) British Columbia "mite-resistant stock, (ii) Buckfast "mite-resistant" stock, and (iii) Canadian unselected stock. Colonies of all nine families were distributed among four apiaries; half of the colonies in each apiary were treated with formic acid to attempt to control tracheal mites. The study documented significant differences in resistance to tracheal mites among the families of bees, even within each of the three stocks. After the first 4 months of study (by November 1993), differences in mite infestations had developed among the nine families. Formic acid treatments had either short-lived effectiveness (1993) or no effect (1994) on tracheal mite infestations, thereby eliminating the opportunity to evaluate colony performance in the absence of mites. Mite infestations varied significantly among apiary sites. This study highlights the value of evaluating sets of colonies headed by sister queens when identifying mite-resistant stock for breeding purposes.

Colonies of honey bees (Apis mellifera L.) were surveyed for the presence of the honey bee tracheal mite (Acarapis woodi Rennie) in Finland between 1991 and 1997. Colony background information and winter loss data were obtained from beekeepers who had taken tracheal mite infested samples. A total of 2116 samples from honey bee colonies of 402 beekeepers were investigated. Infestations were found in 8% of the beekeeping operations and in 10% of the samples inspected. In the last years of the survey more than 20% of apiaries were infested. This increase may be partly explained by tracheal mite infestations found in commercial queen-rearing apiaries. A field experiment with colonies infested at different levels showed that colonies in which 20% or more of bees are infested with tracheal mites have an increased risk of dying during the winter under Finnish conditions. This infestation level was found among colonies in 92% of the infested apiaries. Comparison of the tracheal mite prevalence in apiaries with their winter losses indicated that infestations were associated with colony mortality. The results of this survey point to the high pest potential of the tracheal mite in Finland, in contrast to findings on tracheal mites from elsewhere in Europe. Therefore, strategies to prevent further spread of the mite are highly recommended and methods for effective control should be sought.;

Theoretical Considerations

Based on population dynamics, tracheal mite ( Acarapis woodi ) parasitism of colonies of honey bees ( Apis mellifera ) appears to be, potentially at least, regulatory and stable. Empirical and theoretical considerations suggest, however, that intracolony population dynamics of mite-honey bee worker seem to be unstable in managed situations where honey bee worker population is allowed to grow unchecked. Experimental studies showed that tracheal mite population levels increased in a managed honey bee colony but were impaired in one in which brood rearing was interrupted by loss of the queen. Mite densities but not prevalence were lowered in experimental swarms kept from rearing brood. We propose that swarming reduces mite density within a colony, therefore implicating modern techniques of hive management in the sudden historical appearance of the mite on the Isle of Wight.

Nine species of Tomarus Erichson (formerly Ligyrus Burmeister) occur in the United States, only four of which occur in Florida, including T. gibbosus DeGeer, T. cuniculus (Fabricius), T. neglectus LeConte, and T. subtropicus (Blatchley). Tomarus subtropicus is native to Florida, where it is a turfgrass pest and the most important sugarcane pest. This document is EENY-318, one of a series of Featured Creatures from the Entomology and Nematology Department, Florida Cooperative Extension Service, Institute of Food and Agricultural Sciences, University of Florida.

The organic vegetable industry is flourishing due to consumers preference for organically grown produce over traditionally produced vegetables. As a result, an increase in the variety and selection of many vegetables in retail supermarkets and restaurants throughout the United States has occurred recently. With the new regulation (October 2000) requiring organic seed sources for organically labeled vegetables, many organic growers are searching for certified organic seed. Smaller seed companies have produced the majority of organically produced seed to date. The commercial seed sector is starting to provide a more diverse selection of cultivars, yet there are still many hybrids that are not yet available. For growers in Florida, there is opportunity to produce organic, though it is not widely practiced. This report serves as a guide to organic seed production in Florida. This document is HS981, one of a series of the Department of Horticultural Sciences, Florida Cooperative Extension Service, Institute of Food and Agricultural Sciences, University of Florida.

The lesser pumpkin fly, Dacus ciliatus (Loew), is one of several fruit flies found in Africa and Asia which could be expected to become serious pests of Florida agricultural crops if introduced into this state. This species has not been intercepted in the United States, but prospects are likely for this to occur because of our heavy international traffic. This document is EENY-258 (originally published as DPI Entomology Circular 81), one of a series of Featured Creatures from the Entomology and Nematology Department, Florida Cooperative Extension Service, Institute of Food and Agricultural Sciences, University of Florida.

The Japanese orange fly, Bactrocera tsuneonis (Miyake), is one of the most important pests of citrus in Japan. Extensive outbreaks have occurred in some commercial citrus areas since 1947 when up to 60 percent or more of the fruits were infested. This fruit fly has also been reported to have infested 50 percent of the oranges at Kiangtsin, in the Szechwan Province of southwestern China during 1940. There have been no interceptions of the Japanese orange fly in the United States, probably due in a large part to the protection provided by a US embargo of long standing against citrus from the orient.This document is EENY-263 (originally published as DPI Entomology Circular 56), one of a series of Featured Creatures from the Entomology and Nematology Department, Florida Cooperative Extension Service, Institute of Food and Agricultural Sciences, University of Florida.
