The soft scale, Pulvinaria tenuivalvata (Newstead, 1911), is a major pest of sugarcane in Egypt. This paper provides a redescription and illustration of the adult female based on a microscopic study of the morphology of several adult female specimens and of the type series illustrated by De Lotto (1965) on citronella grass from Uganda. Two paratypes of Pulvinaria saccharia De Lotto, 1964 are al...
Prior to this study, only Megapulvinaria maxima (Green) was known from China. However, a new species Megapulvinaria beihaiensis Wang & Feng, sp. n. is described below and Megapulvinaria maxima is redescribed. A key is provided for the five species now placed in this genus.
A new soft scale insect genus, Sterculicoccus Hodgson, gen. n., is introduced to take a new species, Sterculicoccus tafoensis Hodgson, sp. n., off Triplochiton from Ghana. Sterculicoccus belongs to the Myzolecaniinae and is close to Alecanium Morrison. In addition, a new species of Hemilecanium Newstead, H. cedrelus Hodgson, sp. n., is also described off Cedrela toona from Zambia. Hemilecanium ...
In order to clarify the taxonomic status and to preserve the stability of the species, a neotype is designated for the tuliptree scale: Coccus liriodendri Gmelin (now Toumeyella liriodendri). The adult female of this scale insect is redescribed and illustrated from newly collected specimens in its native range and on its type host, the tulip tree, Liriodendron tulipifera L. (Magnoliales: Magoli...
Flavobacteria and Enterobacteriaceae have been previously reported as scale insect endosymbionts. The purpose of this work was twofold: first, to screen different scale insect families for the presence of these endosymbionts by PCR analyses and second, to elucidate the history of cophylogeny between these bacteria and the insects by analysing a portion of 16S rRNA and 18S rRNA gene sequences by...
