Natural predators are a big help in ridding the lemon tree of these insects. If you have a lot of lemon trees attacked, you can get these lemon tree pests by introducing another predator, the parasitoid wasp. Treating Pests of Lemon Trees. You can sometimes get rid of insects on lemon trees by spraying the trees frequently with oil sprays. Some small insects complete their life cycles in one week, so a weekly wander through the yard may not be frequent enough. Common plant pests in Florida include aphids, mealybugs, scales, whiteflies, thrips, plant-feeding mites, caterpillars, and chinch bugs. Often you will spot evidence of a pest's activity before you see the insect itself.

RUST MITES Rust mites are the most important of the economically relevant groups and include the citrus rust mite and the pink citrus rust mite.

Both species feed on fruit and leaves, which causes damage to epidermal cells. Rust mite injury has a known history of reduc-ing fruit grade in Florida citrus.

Diepenbrock 2 The insects listed in this section are generalist feeders for which citrus is not a preferred host.

A 10X to 15X hand lens is necessary to identify these minute mites. They usually feed in protected places, such as the stylar end of the fruit.

When mite numbers are high, the mites move over the entire fruit. No effective natural enemies are known, but general mite predators feed on rust mites at times.

Young trees are especially susceptible to cold. Asian citrus psyllid waxiness ( KB, PDF) Identification tip: This exotic, aphidlike insect sucks phloem, distorting leaves and shoots.

The yellowish orange nymphs produce abundant white wax. The brownish adults spread citrus greening disease (Huanglongbing). the citrus pest mites are almost invisible to the naked eye. These mites pierce plant surface cells with their mouth parts and suck out the cell contents.

The damage is typical for each pest mite. Citrus red mite Citrus red mite, which damages both the leaves and fruit, is one of the world’s worst pests of citrus. Citrus rust mites, as well as other mites found on citrus (such as spider mites), are usually well controlled by a complex of natural enemies, including predatory mites.

However, these predatory mites are usually quite sensitive to insecticides, so the elimination of these predators allows for the drastic increase of the pest mite population.

Mites (Acari) are arthropods, a group that includes insects and spiders. Some mites are large enough to be visible to the naked eye while others can only be seen with a hand lens or microscope.

In Western Australia, five species of mite are potential pests: two-spotted mite, citrus bud mite, citrus rust mite, oriental spider mite and broad mite.

SCALE INSECT AND MITE ENEMIES OF CITRUS TREES. are protected from direct sunlight and free movement of the air, hence trees of dense growth, unpruned, are almost certain to have their cen- ters, at least, scaly.

A well-opened and pruned tree, in which free access is given to light and air, is much less apt to be badly attacked. The flush growth of citrus trees attacked by leafminer will look unsightly, but the best course of action is to leave it alone and let the natural enemies of the citrus leafminer feed on and parasitize the larvae in the mines, rather than trying to control this pest with insecticides.

Numerous insect and mite species are present in citrus and have the potential to reduce yields by feeding on the leaves, roots, branches and developing fruit and by serving as vectors of diseases that affect the health of citrus trees.

Most of these potential pests are maintained at low population levels by the action of natural enemies. We propose to investigate the biology of .What Is a Pesticide and Fungicide Spray for Citrus Trees?. Citrus trees are susceptible to multiple insect pests and fungal diseases.
