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...

this study compared the different effects of form-focused guided planning vs. meaning-focused guided planning on iranian pre-intermediate students’ task performance. the study lasted for three weeks and concentrated on eight english structures. forty five pre-intermediate iranian students were randomly assigned to three groups of guided planning focus-on-form group (gpfg), guided planning focus...
15 صفحه اولIsolation 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...

Evidence 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,...
