Susceptibilities 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 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 کاملPredators of the rosy apple aphid, Dysaphis plantaginea (Pass.), in Asturian (NW Spain) apple orchards
Alternative strategies to the common practice of spraying with insecticide in order to control the rosy apple aphid Dysaphis plantaginea (Pass.) (Homoptera: Aphididae) are required. Biological control by natural enemies is a possible tool. In Asturies, despite the tradition of growing local cider apple trees, there are no studies about the community of D. plantaginea predators and their impact ...
متن کاملWeak Spatial and Temporal Population Genetic Structure in the Rosy Apple Aphid, Dysaphis plantaginea, in French Apple Orchards
We used eight microsatellite loci and a set of 20 aphid samples to investigate the spatial and temporal genetic structure of rosy apple aphid populations from 13 apple orchards situated in four different regions in France. Genetic variability was very similar between orchard populations and between winged populations collected before sexual reproduction in the fall and populations collected fro...
متن کاملCloning and characterization of mariner-like elements in the soybean aphid, Aphis glycines Matsumura.
Soybean aphid, Aphis glycines Matsumura (Hemiptera: Aphididae), is currently the most important insect pest of soybean (Glycine max (L.) Merr.) in the United States and causes significant economic damage worldwide, but little is known about the aphid at the molecular level. Mariner-like transposable elements (MLEs) are ubiquitous within the genomes of arthropods and various other invertebrates....
