Abstract

Integrated control of the coffee mealybugs and scales forming moulds.

Abstract

Recommendations are presented for controlling Planococcus kentae, P. citri, Coccus alpinus, Saissetia coffeae and Ceroplastes brevicauda [Gascardia brevicauda] on coffee in Kenya, where they are attended by ants and produce honeydew that provides a substrate for the growth of sooty moulds (Cladosporium). The integrated control described depends on the chemical control of ants with Amdro [hydramethylnon] baits, Inacide [of unstated composition], or sprays of Supracide [methidathion], ethion, Dursban [chlorpyrifos] or Decis [deltamethrin]. This encourages the survival of predators and parasitoids that would otherwise be killed by the ants, and also controls several other kinds of insect pests on coffee.
