Fruit Crops: Apple

Chapter

Abstract

Mealybugs have been reported causing damage to apples in New Zealand, South Africa, Japan, New York, Florida and California. Mealybugs shelter in leaf axils, under bark and in the calyx of fruit. Sucking sap will to some extent devitalize the tree. Besides, the pest excretes a honeydew substance which can then be a suitable source for sooty mould to develop. Aminocarb was best against the mealybugs in New Zealand. In S. Africa, although mealybugs were present in many orchards, they were well controlled in most cases, and serious infestations were associated with inefficient or infrequent spraying. Clothianidin is one of the few registered products for control of mealybug in apples. Dormant, petal fall, summer and post harvest sprays for Ph. aceris are recommended in British Columbia. Parasitoids are likely the most effective biocontrol agents of apple mealybugs.
