Ceroplastes cirripediformis Comstock
Common name: Barnacle scale.
Host plants: Polyphagous.
Morphology The covering scale is convex, greyish with pink spots, the female body is red-brown, about 3-5mm in length, antenna 7-segmented, ventral tubular ducts, without broad inner filaments, dorsal setae capitate.
Geographical distribution: In most of the warmer regions of the world.
Life history: This scale infests the leaves and branches of its host plants. It usually completes only one annual generation, but in Egypt it raised two. Fecundity may be over 1.000 eggs/female. Males are rare. The pest excretes much honeydew that is harvested by ants.
Biological control: The scale is attacked by several Aphelinidae, such as Coccophagus ceroplastes Howard and Metaphycus spp., by Aprostocetus ceroplastae, by Microterys nietneri and by Scutellista caerulea. Some of these natural enemies usually control the pest, unless attacked by hyperparasites or killed by pesticides. .
