Seasonal 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...
متن کاملRole of neonicotinyl insecticides in Washington apple integrated pest management. Part I. Control of lepidopteran pests
Three neonicotinyl insecticides, acetamiprid, thiacloprid and clothianidin, were evaluated for their impact on four species of lepidopteran pests of apple in Washington, the codling moth, Cydia pomonella (L.), the Pandemis leafroller, Pandemis pyrusana Kearfott, and the obliquebanded leafroller, Choristoneura rosaceana (Harris), and Lacanobia subjuncta (Grote & Robinson). None of the neonicotin...
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 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 کاملThe nutritional value of aphid honeydew for parasitoids of lepidopteran pests
Intake of sugar-rich foods by adult parasitoids is crucial for their reproductive success. This is an aspect of parasitoid biology that warrants special attention in the biological control of pests. Facilitating access to suitable foods might help optimize the efficacy of parasitoids as biological control agents. In situations where nectar is not readily available, homopteran honeydew can be a ...
