Selectivity 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 کاملSpatial 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 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...
متن کاملNatural enemies of woolly apple aphid (Hemiptera: Aphididae) in Washington State.
Woolly apple aphid, Eriosoma lanigerum (Hausmann), has become a pest of increasing importance in Washington apple orchards in the past decade. The increase in aphid outbreaks appears to be associated with changes in pesticide programs and disruption of biological control. We sampled woolly apple aphid colonies in central Washington apple orchards for natural enemies of this pest from 2006 to 2...
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...
