Minimal Damage

There are no major insect pests on carrot in Florida. The greatest concern for growers has been root damage from soil pests, particularly wireworms (southern potato and tobacco), cutworms (variegated, granulate, black), and mole crickets, all of which are sporadic. Occasional minor pests include leafminers (especially the vegetable leafminer), aphids (green peach and melon), and weevils (especially vegetable weevils). Other arthropods that may occasionally cause minimal damage to carrots in Florida include armyworms (fall, beet, and southern), field crickets, mites (especially twospotted spider mite), and plant bugs (including tarnished plant bug).

Twospotted Spider

California strawberries have two major arthropod pests—the twospotted spider mite, Tetranychus urticae and the western tarnished plant bug, Lygus hesperus, which result in significant losses to the yield and quality of marketable berries. Other important insect pests that are frequently seen in strawberry include the greenhouse whitefly, Trialeurodes vaporariorum and the western flower thrips, Frankliniella occidentalis that cause varying levels of damage depending on the level of infestation. Chemical pesticides play a major role in managing these pests but not without the associated risk of pesticide resistance and environmental safety. Two field studies were conducted in commercial strawberry fields in Santa Maria, one of the strawberry growing areas in California Central Coast, to determine the efficacy of chemical, botanical and microbial pesticides in the integrated pest management (IPM) of strawberry. Chemical, botanical and microbial pesticides were evaluated against T. urticae in a small plot study in 2013 and against L. hesperus and other insect pests in a large plot study in 2015 in commercial strawberry fields. Bug vacuums were also used in the 2015 study. Results demonstrated that non-chemical alternatives can play an important role in strawberry IPM.

Predatory Gall Midge

The predatory gall midge, Feltiella acarisuga (Vallot), is one of the most effective and widespread natural enemies of spider mites (Tetranychidae) (Gagne 1995). It is a particularly important natural enemy of the twospotted spider mite, Tetranychus urticae Koch, in a number of cropping systems (Opit et al. 1997). F. acarisuga could be particularly useful for integrated pest management of spider mites that attack greenhouse crops (Gillespie et al. 1998). This document is EENY-269, 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.

Twospotted Spider

The twospotted spider mite, Tetranychus urticae Koch, has been controversial in its taxonomic placement. About 60 synonyms included under this species have compounded the controversy. The body of a spider mite is separated into two distinct parts: (1) the gnathosoma and (2) the idiosoma. The gnathosoma includes only themouthparts. The idiosoma is the remainder of the body and parallels the head, thorax and abdomen of insects. After hatching from the egg, the first immature stage (larva) has three pair of legs. The following nymphal stages and the adult have four pairs of legs. This document is EENY-150 (originally published as DPI Entomology Circular 89), 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.

Predatory mites such as Neoseiulus californicus McGregor (Fig. 1) and Phytoseiulus persimilis Athias-Henriot (Fig. 2) feed on important fruits and ornamental pests such as the twospotted spider mite (Tetranychus urticae Koch), broad mite (Polyphagotarsonemus (Stenotarsonemus) latus Banks), cyclamen mite (Tarsonemus pallidus L.), and other mite species. These predatory mites are associated with several agricultural cropping systems including strawberries, raspberries, roses, grapes, citrus, ornamentals, and vegetables. Predatory mites have been used as an alternative to miticides on a variety of crops. Their commercial availability is crucial. This document is HS1000, one of a series of the Horticultural Sciences Department, Florida Cooperative Extension Service, Institute of Food and Agricultural Sciences, University of Florida.

Chewing insects can cause serious yield and quality losses in potatoes by feeding on the leaves, stems or tubers. Sucking insects can cause direct losses from feeding and indirect losses by transmitting viral diseases. The most important of these insects are described below. A table at the end of the chapter lists insecticides currently registered for potatoes.  This document is ENY-469 (which replaces ENY-438), one of a series of the Entomology & Nematology Department, Florida Cooperative Extension Service, Institute of Food and Agricultural Sciences, University of Florida.

The southern pine coneworm, Dioryctria amatella (Hulst), also commonly referred to as a pitch moth, is consistently one of the most damaging insect pests of pine seed orchard crops throughout the southeastern United States (Ebel et al. 1980). Less well-recognized is that this widespread and frequently occurring insect also attacks a variety of other parts of pines (Pinus spp.) besides cones. Caterpillars can be found feeding on and in buds, male and female flowers, shoots, branches and stems of all ages and sizes, as well as in conelets (i.e., first-year cones) and second- year cones (Ebel 1965, Ebel et al. 1980, Goolsby et al. 1972). This document is EENY-325 (originally published as DPI Entomology Circular 393), 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.

This species was first described from Jamaica and is widespread in the West Indies. It may have first become established in south Florida as recently as the early 1950's. Its scientific name (Gryllus assimilis or Acheta assimilis) was applied to all New World field crickets until 1957. This document is EENY-069, 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.
