Mealybugs are serious pests of orchids (Table 56.1), and next to scale insects, they are probably the most difficult to control pests of orchids in homes and greenhouses. Nearly 300 species of mealybugs are known from Canada and the United States. Fortunately, only a few species are common or serious pests of orchid (Johnson 2014). The most important pest of this crop is the long-tailed mealybug Pseudococcus longispinus in California and Canada. In Hawaii, P. longispinus and Dysmicoccus brevipes are common on orchids (https://www.aos.org/Default.aspx id=511). The mealybugs problem are reported on many orchid species like Cymbidium, Dendrobium, Cattleya, Calanthe, Phaius, Phalaenopsis, Pholidota, etc., worldwide. Pineapple mealybug (D.brevipes), long-tailed mealybug (P. longispinus), jack beardsley mealybug (Pseudococcus jackbeardsleyi), obscure mealybug (Pseudococcus viburni), and orchid mealybugs (Pseudococcus microcirculus and Pseudococcus dendrobiorum) are the major species due to their occurrence in serious proportions in many parts of the world (Bronson 2009). Only P. dendrobiorum and P. longispinus are known to infest orchids in greenhouses of tropical and subtropical regions of India. In most of Canada and the United States, the long-tailed mealybug (P. longispinus) is probably the most common and problematic species on orchids, particularly in homes and greenhouses.
