Arthropod-Plant Interactions, 6/2: 181-186. 28 (3), 241-249. Aphids that are captured or harassed produce an alarm pheromone that alerts other aphids of danger. American Potato Journal. High population levels of M. euphorbiae cause direct feeding damage. Records of alien insect species from sub-Antarctic Marion and South Georgia Islands. The adult potato aphid is a large, slender aphid with long, green cornicles, long legs, and a long cauda. Characterization of Solanum chomatophilum resistance to 2 aphid potato pests, Macrosiphum euphorbiae (Thomas) and Myzus persicae (Sulzer). Table 5. Lakewood, Colorado, USA. Overwintering of rose-infesting aphids (Homoptera: Aphididae) at Wenatchee, Washington State, USA, with redescription of Wahlgreniella nervata (Gillette). Horticultural Science, 39/2: 74-80. One female can give birth to anywhere from a few to 50 offspring in a single day. (1991) listed 67 plant viruses that M. euphorbiae is capable of transmitting. Resistance to the pink potato aphid, Macrosiphum euphorbiae, in two accessions of Lycopersicon hirsutum f. glabratum. Potato leafroll virus detection by RT-PCR in field-collected aphids. African Entomology, 6(2):366-369; 21 ref. In: Entomology Circular (Gainesville), 2 pp. Denmark HA, 1990. Raboudi F; Ben Moussa A; Makni H; Marrakchi M; Makni M, 2002. The winged form has dusky lateral abdominal sclerites and fairly heavily pigmented wing veins. A non‐gall‐forming aphid, Macrosiphum euphorbiae, ... Aphids successfully completing their life cycle have a life‐time energy consumption of 30.58 joules of which 18% is lost as heat during respiration (R), 30% is contained in honeydew (F + U), 1% is contained in exuviae (Pe). Apterous adults usually appear shinier than nymphs. Journal of Insect Physiology, 56/6: 575-585. Dot immuno-binding assay has also great potential for mass screening (Singh et al., 1993). Additionally, the European red ant, Myrmica rubra, tends some colonies of M. euphorbiae. Some isolates belonged to the Wilga type (Varveri, 2006). Feng M G, Johnson J B, Halbert S E, 1992. Leaf roll due to aphid feeding occurs earlier in the season than the similar leaf roll symptoms caused by aphid-transmitted potato leaf roll virus. These phenomena might be related to the observed changes in phloem exudates composition (free amino acids, sugars) in virus infected plants. Raboudi, F., H. Makni, M. Makni. The siphunculi are relatively shorter than in the species discussed above. Interactions of transgenic-Bt potato resistance to Colorado potato beetle with the fitness and behavior of the potato aphid Macrosiphum euphorbiae. PAP applied to the leaf surface may not be sufficient to enter the cell during aphid feeding (Lodge et al., 1993). (Legarrea, et al., 2012; Raboudi, et al., 2011; van Emden and Harrington, 2007). It is suggested that conservation biological control is the best strategy for managing aphid pests in horticultural systems because of problems related to the isolation and artificial production of entomopathogenic fungi (Díaz et al., 2008). The origin of potato aphid is thought to be North America, though it is now found widely around the world. Resistance to carbamate, organophosphate and pyrethroid insecticides in the potato aphid (Macrosiphum euphorbiae). The virus needs to cross the gut epithelium cells and circulate through the hemocoel to reach the aphid's salivary glands. Pompon, J., D. Quiring, P. Giordanengo, Y. Pelletier. Finlayson, C., A. Alyokhin, E. Porter. reproduction in which fertilization and development take place within the female body and the developing embryo derives nourishment from the female. Large colonies of aphids can extract large amounts of nutrients from a plant. The repellency of various essential oils to the aphids Aphis gossypii, Myzus persicae and M. euphorbiae in pepper crops (Capsicum annuum) was evaluated in greenhouses. A grassland with scattered trees or scattered clumps of trees, a type of community intermediate between grassland and forest. When reproduction is sexual, the aphids lay eggs that overwinter. Even the winged forms can be red. WMV and ZYMV are transmitted on the non-persistent mode: they are acquired and transmitted during very short probes (a few seconds to minutes), and their retention period in the vector is relatively short (a few hours). Weeds such as ragweed, lambsquarter, jimsonweed, pigweed, shepherdspurse, and wild lettuce are also common food plants. Pandora neoaphidis was the predominant entomopathogenic fungus affecting M. euphorbiae on lettuce in a study in the central Iberian Peninsula. British Sugar Beet Review, 73:2-7. Entomologia Experimentalis et Applicata, 83/2: 181-187. Some members of this species have wings, while others do not. Shands WA; Simpson GW; Wave HE, 1972. Delrio G; Luciano P; Floris I; Cabitza F; Cubeddu M; Cabras P, 1989. Development and survival of Aulacorthum solani, Macrosiphum euphorbiae and Uroleucon ambrosiae at six temperatures. Cultural inputs into integrated crop management and minimizing losses of processing tomatoes to pests in the US. Oil application may change the chemical profile of the plant odor by masking or adding a repellent effect, thus modifying host-selection behavior of the insect vectors (Cen et al., 2002). Potato aphid monitoring and biocontrol in processing tomatoes. Macrosiphum euphorbiae (potato aphid); mixed life stages on garden tomato leaf (Solanum lycopersicum). Revista Verde de Agroecologia e Desenvolvimento Sustentável, 6(5):21-24. Skirvin DJ; Kravar-Garde L; Reynolds K; Wright C; Mead A, 2011. Aphid species that form large colonies and are capable of transmitting the virus to lettuce include Aulacorthum solani that can be easily misidentified with M. persicae. In Greece, in 2006 high infection rates by PVY were observed in both noncertified seeds and ware potatoes, at rates up to 100% of the suspected plants or tubers. Journal of Pest Science, 84(2):229-233. http://www.springerlink.com/content/697247l336273528/. Further details may be available for individual references in the Distribution Table Details section which can be selected by going to Generate Report. We work in a range of crops and have developed biologically based IPM programs to control the major pests. (Diptera: Cecidomyiidae). New Phytologist, 187(4):1089-1101. http://www.blackwell-synergy.com/loi/nph, Digilio MC; Sasso R; Leo MGdi; Iodice L; Monti MM; Santeramo R; Arpaia S; Guerrieri E, 2012. Journal of Chemical Ecology, 32/8: 1719-1729. Journal of Vegetable Crop Production. Its host plants, such as potatoes and many other crop species can be found mainly in agricultural fields, but also in grasslands and suburban areas such as greenhouses, gardens, and parks. Cécile Desbiez, Hervé Lecoq, in Reference Module in Life Sciences, 2020. Journal of Insect Physiology, 56/6: 610-615. Resistance of M. euphorbiae to the carbamate pirimicarb was found to be associated with a one-point mutation in the gene encoding AChE. Recently, a multiplex PCR assay was described that characterizes PVY isolates and identifies strain mixtures, including NTN- and NTN-like isolates (Lorenzen et al., 2006b). Integrated strawberry production: experiences with ladybirds to control aphids. Kuroli G; Pocsai K; NTmeth L, 1999. Patch EM, 1925. A unique PVYO strain was described from Egypt (Abdel-Halim et al., 2000), as well as a PVYN strain (El-Mohsen et al., 2003), PVYNTN (Amer et al., 2004). Maine Agr. American Potato Journal, 74(5):305; 16 ref. Palmer MA, 1952. Using the individually cloned DNAs of FBNSV and PNYDV, it has recently been demonstrated that the proteins encoded by DNA-N of FBNSV and PNYDV are mandatory for virus transmission by vector aphids.
