| Abstract:
Phytophagous mites of the genus Tetranychus are commonly found attacking ornamentals in production plants and indoor landscapings. The control of those pest organisms is normally done by means of chemical pesticides. Problems of pest resistance and side effects of those products' use have led growers to look for alternative pest control methods. Biological control has been practiced on such ornamental crops as roses, chrysanthemum and different tropical foliage crops, by using almost exclusively the predatory phytoseiid mite Phytoseiulus persimilis Athias-Henriot. This predator is sold commercially by a number of suppliers in different countries. Other species of predators as well as species of pathogens have not been sufficiently studied. More extensive use of biological control depends upon further explorations of prospective species of predators and pathogens, probably waiting to be discovered in poorly studied areas around the world. | |
