A diagram of the life cycle is given, and photographs illustrate the type of damage these mites do to lemons and Valencia oranges. The natural enemies of the brown citrus rust mite are described and a beautiful photograph of the predatory mite Euseius victoriensis is given. This phytoseiid mite is described as an effective predator, particularly in inland citrus areas and in sub-coastal Queensland. Other phytoseiid mites are listed as important in other geographic regions, and other natural enemies are mentioned, including predatory stigmaeid mites, cecidomyiid fly larvae, and fungal pathogens. Pollen also can be provided by eucalyptus trees serving as windbreaks.
Monitoring is an integral component of the management program.
A graph takes the number of predatory mites per 100 leaves into account as well as the number of rust mites, and miticides are recommended that are least toxic to the predatory mites. This is of particular interest to Florida s citrus growers because T. citricida is expected to transmit tristeza virus to trees grafted on susceptible rootstocks. In addition, an Entomophthora fungus attacks the aphids. It is likely that these aphids are relatively unimportant in Australia due to the combined effects of natural enemies and because the citrus rootstocks recommended are resistant or tolerant to tristeza. Unusual facts contained within this book include the description of a pest spider.
