What are parasitoids?
Populations of scale insects and mealybugs are often kept in check by natural enemies. Parasitoids are wasps or flies that use scale insects as food and a place to develop (figure 23). They are only obvious when they emerge from the host insect, usually leaving one or more small holes in the waxy scale cover (figure 24). Predatory insects, mites, spiders, and pathogenic fungi also commonly attack scale insects. For these reasons, it may not be necessary or feasible to use chemical controls.
How do scale insects get their name?
Scale insects derive their name from their barnacle-like appearance on host plants (figure 1). They are covered with a waxy coating or cover, which hides and protects the insect and its eggs underneath. Mealybugs have a white cottony/waxy body with no hardened covering.
How do armored scales reproduce?
Besides their hardened coating, armored scales differ from soft scales in several ways: 1 They typically reproduce sexually. 2 Females generally produce only one generation per year, consisting of a small number of eggs (a dozen or fewer). 3 They feed directly on plant cells and xylem (tissues that conduct water), so there is no sugary honeydew or sooty mold produced. 4 They cause plants to decline slowly. Symptoms of infested plants include canopy thinning. Thinning is often mistaken for plant stress, since the scale insects are smaller and blend into the bark. Most are found on woody trees and shrubs, but a few are known to attack grasses.
What is the largest scale insect?
Giant Scales . Giant scales (family Monophlebidae) are among the largest scale insects. They are commonly misidentified as mealybugs, because they have an exterior ovisac and retain well-developed legs (figure 20). Honeydew and sooty mold are common when giant scales are present.
