Broad mites inject a toxin from their saliva as they feed. Leaves become twisted, hardened and distorted with bronzed lower surfaces. Young terminal buds can be killed. Leaves frequently turn downward. Broad mites have a wide host range and can feed on African violets, ageratum, begonia, cyclamen, dahlia, gerbera, gloxinia, hibiscus, ivy, jasmine, impatiens, New Guinea impatiens, lantana, marigold, snapdragon, verbena, and zinnia.
Broad mites can also infest vegetable bedding plants such as beans, peppers and tomatoes.
F favor the development of cyclamen mites. Severe outbreaks may occur in greenhouses in the fall and winter months. Females may live for up to one month and can reproduce without mating. Cyclamen mite females lay 2 to 3 eggs per day for up to two to three weeks. The eggs are deposited in moist, dark places in crevices and at the base of the plant.
