Salicicola kermanensis

Salicicola kermanensis (Lindinger).

Common name: Iranian poplar scale.

Taxonomic placing: Insecta, Hemimetabola, Hemiptera, Sternorrhyncha, Coccoidea, Diaspididae.

Host plants: Poplar (Populus spp.), Salix spp.

Morphology: Salicicola kermanensis is pupillarial, the female body remaining within the dark-brown exuvium of the 2nd-stage nymph. The female is elongate-oval, convex, about 1.3 mm in length, and the shield is short, also convex.

Geographical distribution: The Middle East, Southern Asia, Morocco, Yugoslavia, and Greece.

Life history: A univoline species. The females lay about 25 eggs, and the hatching crawlers suffer from high mortality.

Economic importance: An important pest of poplars, whose heavy infestations can tree wilting.

Sampling: Four branches/tree are selected in early spring and the number of scales found thereon are counted per surface unit.


Plant tolerance: Various poplar cultivars are relatively less infested. Reduced irrigation negatively affects the pest’s populations.

Biological control: Several Aphelinidae attack the pest, including Aphytis mytilaspidis. Predators include the Coccinellidae Nephus fenestratus (Sahlberg), Chilocorus bipustulatus, Pharoscymnus Spp., and a Scymnus sp. Their effect on pest numbers and damage is not known.
