Occurrence and Control Methods of the Comstock Mealybug in Pear Orchards
(1) Occurrence patterns The Comstock mealybug belongs to the order Homoptera, family Pseudococcidae. Also known as the pear mealybug, plum mealybug, and mulberry mealybug. It generally produces three generations per year, overwintering as eggs and nymphs in hidden places such as cracks in the rough bark of tree trunks, bagged diseased and pest-infested fruits scattered in the orchard, weeds around the root zone, soil clods, and fallen leaves. Adults and nymphs suck the sap of tender buds, tender shoots, and fruits.
