We report a 4-year-old boy with two areas of woolly hair in the right parietotemporal region and a linear epidermal nevus in the areas of woolly hair as well as in the ipsilateral hemiface and chin. Evaluation by scanning electron microscopy showed woolly hair with oval transverse section and longitudinal groove. A complete examination ruled out associated anomalies.

We studied the adult ambulatory response of the predator, Laricobius nigrinus Fender (Coleoptera: Derodontidae), to odors from its prey, Adelges tsugae Annand, the hemlock woolly adelgid, and foliage of hemlock woolly adelgid, host hemlocks (Tsuga spp.), and other conifers. Both the predator and hemlock woolly adelgid are apparently native to western North America, but the predator is being re...

Woolly hair nevus is a rare condition characterized by a structural anomaly of the hair, restricted to certain areas of the scalp. The hair becomes coiled and slightly hypopigmented. The term woolly hair refers to changes that affect all the scalp and has a hereditary character. We present a case of woolly hair nevus, that developed at the age of 2 years, associated with dental diastema and ver...

The seasonal abundance of woolly apple aphid (Eriosoma lanigerum Hausmann) was studied from 2005 to 2008 in commercial orchards in central Washington State. There was a single period of crawler migration on the tree trunks each year lasting from 7 to 16 wk. The peak period of crawler activity ranged from early June to late July, although peaks in June were more common. In one orchard, peak dens...

We present here the first complete genomic Aphid lethal paralysis virus (ALPV) sequence isolated from cucumber plant RNA from East Timor. We compare it with two complete ALPV genome sequences from China, and one each from Israel, South Africa, and the United States. It most closely resembled the Chinese isolate LGH genome.

Reproduction of the woolly apple aphid, Eriosoma lanigerum (Hausmann), can take place parthenogenetically or sexually when both host plants, apple (Malus domestica Borkh.) and elm (Ulmus americana L.) are available. Since elm is not commonly grown in New Zealand, E. lanigerum, a major pest of apple, is thought to reproduce only parthenogenetically here. During our studies between 1999 and 2003,...

Eight novel microsatellite primer pairs are presented for Eriosoma lanigerum, representing the first microsatellite markers available for this genus. Loci were characterized for 27 individuals from one single orchard in Central Chile. All loci were polymorphic within E. lanigerum (three to 11 alleles per locus; observed heterozygosity ranging from 0.41 to 0.93), and are therefore useful for pop...

The hemlock woolly adelgid (Adelges tsugae Annand) is an invasive species causing high mortality of eastern hemlock (Tsuga canadensis (L) Carriere) in the forests of eastern North America. Recent findings revealed that sapling eastern hemlocks artificially infested with hemlock woolly adelgid in a plantation setting responded to the insect with an array of induced resin volatile changes. Here w...
