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 کاملSelectivity of Four Insecticides to Woolly Apple Aphid, Eriosoma Lanigerum (Hausmann) and its Sole Parasitoid, Aphelinus mali (Hald.)
Four insecticides were tested for their suitability to an integrated pest management program of woolly apple aphid (WAA). The tested insecticides were imidacloprid, pirimicarb, cartap and petroleum oil. Three indices were developed to determine the degree of selectivity of studied insecticides and to determine their suitability to WAA IPM program. WAA index used to measure the efficacy of the i...
متن کاملWoolly apple aphid Eriosoma lanigerum Hausmann ecology and its relationship with climatic variables and natural enemies in Mediterranean areas
A multilateral approach that includes both biotic and climatic data was developed to detect the main variables that affect the ecology and population dynamics of woolly apple aphid Eriosoma lanigerum (Hausmann). Crawlers migrated up and down the trunk mainly from spring to autumn and horizontal migration through the canopy was observed from May to August. Winter temperatures did not kill the ca...
