Carvalho LMde; Bueno VHP; Martinez RP, 2002. Zashchita Rastenii (Moskva), No. Infected plants are more severely affected if PVY occurs in complex with other viruses, especially PVX. The average density ranged from 1.5 to 25.7 aphids per compound leaf, and the maximum density ranged from 3.0 to 64.2 aphids per compound leaf (Parker, 2005). It feeds on the upper leaves and new shoots. Koppert offers different solutions for biological pest control of Potato aphid. It has also been suggested to affect stylet penetration behavior, possibly via interference with the sensory structures of the aphid labium, stylets, or epipharynx (Harris, 1977, 1983). In: Distribution Maps of Plant Pests, Wallingford, UK: CAB International. Nakata T, 1995. Animals with bilateral symmetry have dorsal and ventral sides, as well as anterior and posterior ends. Several polyphagous aphids are sometimes found on rose, especially in glasshouse culture (Tables 5 and 6). Macgillivray, M., G. Anderson. Tao CC, 1999. Table 4. Major predators include coccinellids (ladybirds) larvae and adults, and syrphid and lacewing larvae. Entomologia Experimentalis et Applicata, 115:107-115. Other potential PLRV vectors include black bean aphid, Aphis fabae Scopoli; buckthorn aphid (buckthorn–potato aphid), Aphis nasturtii (Kaltenbach); the melon (cotton) aphid complex, Aphis gossypii Glover [including Aphis frangulae (Kaltenbach)]; shallot aphid, Myzus ascalonicus Doncaster; violet aphid, Myzus ornatus Laing; mottled arum aphid, Aulacorthum (Neomyzus) circumflexum (Buckton); foxglove aphid (glasshouse–potato aphid), Aulacorthum solani (Kaltenbach); damson–hop aphid, Phorodon humuli (Schrank); the stolon-infesting bulb and potato aphid, Rhopalosiphoninus latysiphon (Davidson) and mangold aphid, Rhopalosiphoninus staphyleae (Koch). The use of tolerant varieties, biological control, and sprays of thyme oil, pyrethrin and insecticidal soap are acceptable for use against M. euphorbiae on organically certified crops in the USA (UC IPM Online, 2005). © 2015 Biological Services. Recombination analysis grouped isolates of PVYSYR into three recombination patterns, SYR-I, SYR-II, and SYR-III, which varied in the first 700 nucleotides of their genomes, with the second recombination pattern, SYR-II, the most frequent. Substantial loss in potato yield due to the early population of vectors of two aphid-borne viruses in Egypt. Non-host-alternating species restricted to Rosa. PVYO and PVYN were found in Spain (Blanco-Urgoiti et al., 1996). change in fur color), or age-related changes to be polymorphic. Foster et al. Environmental Entomology, 39(5):1500-1505. In addition, more alatae are produced on infected plants, which may stimulate ZYMV spread. Wingless aphids are 1.7 to 3.6 mm long, while winged forms are 1.7 to 3.4 mm long. Goldansaz SH; McNeil JN, 2003. Early presence of an enolase in the oviposition injecta of the aphid parasitoid Aphidius ervi analyzed with chitosan beads as artificial hosts. The NIb protein is the putative RNA-dependent RNA polymerase, which also forms nuclear inclusions. Pests and diseases in 2004. The strains can also be detected and differentiated by nucleic acid spot hybridization using radioactive and nonradioactive probes (Baulcombe and Fernandez-Northcote, 1988; LeClerc et al., 1992), RT- and IC-PCR (e.g., Barker et al., 1993; Weidemann and Maiss, 1996). 2012. Nature Biotechnology, 16(13):1365-1369; 29 ref. Mitt. Anholocyclic populations (in which female aphids reproduce only by parthenogenesis) occur throughout the rest of its global range. List of Aphidoidea (Hemiptera) of China. European Journal of Entomology, 110/2: 263-270. Kaloshian, I., M. Kinsey, D. Ullman, V. Williamson. Phytopathology, 98(11):1233-1241. http://www.apsnet.org/phyto/, Godzina M; Staniaszek M; Kiekiewicz M, 2010. We do not consider sexual differences (i.e. 77. This result is contrary to the observations of Vanderveken (1968), who had found that surfactants used in commercial preparations had no inhibitory effect.

The ADW Team gratefully acknowledges their support. 36 (4), 365-375. Parasitoids (Hymenoptera: Aphidiidae and Aphelinidae) and their effect on aphid (Homoptera: Aphididae) populations in irrigated grain in southwestern Idaho. PVY was detected also in Lebanon including an isolate causing superficial necrosis on potato tubers (Le Romancer et al., 1994), probably a PVYNTN isolate.
