Spatial Variation of Woolly Apple Aphid (eriosoma Lanigerum, Hausmann) in a Genetically Diverse Apple Planting
There is an increasing requirement to breed durable resistances to woolly apple aphid (WAA) into apple cultivars. Genetically diverse apple plantings have been established in New Zealand with one aim to identify new sources of resistance to this pest, and also to allow the computation of parameters of genetic interest. Such computations are hindered by the uneven distribution of the pest in the...
متن کاملIsolation and characterization of microsatellite loci from the woolly apple aphid Eriosoma lanigerum (Hemiptera: Aphididae: Eriosomatinae).
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...
متن کاملEvidence of sexual reproduction of woolly apple aphid, Eriosoma lanigerum, in New Zealand
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,...
متن کاملSusceptibilities of apple aphid and spirea aphid collected from apple in the Pacific Northwest to selected insecticides.
Laboratory bioassays using leaf disks of apple dipped in test solutions of insecticides demonstrated that the apple aphid, Aphis pomi De Geer, and the spirea aphid, Aphis spiraecola Patch, differed significantly in susceptibility to a number of insecticides registered for control of aphids on apple (Malus spp.). Compared with A. pomi, A. spiraecola was approximately four- and three-fold less su...
متن کاملSeasonal phenology of woolly apple aphid (Hemiptera: Aphididae) in Central Washington.
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...
