Extract

The bionomics and ecology of two Adelgids, Adelges knucheli (Schneider-Orelli & Schneider) and A. joshii (Schneider-Orelli & Schneider), first recorded from West Pakistan by Yaseen & Ghani (1966), have been studied by Ghani & Rao (1966). During surveys for the natural enemies of Adelgids in West Pakistan forests, another Adelges sp. on fir and three Pineus spp. on pines were found. They differed from described species in shape, size and arrangement of the wax pores on the sclerotised plates of the head and thorax, characters considered by Underwood (1963) the best for identifying apterous Adelgid adults. They are here described as new, and notes are given on their biologies seen in marked colonies under field conditions. All four species are monomorphic and anholocyclic.
