BIOLOGY/ECOLOGY Dispersal mechanisms Flight range of winged adults is very limited. Long-range dispersal of eggs, immature stages and adults is manmediated with the transport of infested plant material. Reproduction The taxonomic status of this alien aphid is problematic, and hence the interpretation of biological information is difficult. Moreover, different biotypes exhibiting host preference...

1 Monsanto Company (Monsanto) has petitioned APHIS for a determination that MON 87705 soybean is unlikely to pose a plant pest risk (Rogan, 2009) and, therefore, should no longer be a regulated article under APHIS’ 7 Code of Federal Regulations (CFR) part 340. APHIS administers 7 CFR part 340 under the authority of the plant pest provisions of the Plant Protection Act of 2000 . This plant pest ...

Little is known about the mechanisms by which plant genotype shapes arthropod community structure. In a field experiment, we measured the effects of milkweed (Asclepias syriaca) genotype and ants on milkweed arthropods. Populations of the ant-tended aphid Aphis asclepiadis and the untended aphid Myzocallis asclepiadis varied eight- to 18-fold among milkweed genotypes, depending on aphid species...

Pioneer Hi-Bred International, Inc. (referred to as “Pioneer” hereafter) has petitioned APHIS (USDA-APHIS Petition Number #11-244-01p, referred to as “Petition”) for a determination that genetically engineered (GE) corn (Zea mays) event DP-ØØ4114-3 (referred to as “4114 maize” or “4114”) is unlikely to pose a plant pest risk and, therefore, is no longer a regulated article under regulations at ...

Subspecies Dysaphis pavlovskiana indica Chakrabarti & Medda, 1993 is given species status (Dysaphis indica Chakrabarti & Medda, 1993, new status). Aphis plantaginis asiatica Daniyarova, 1979 is a synonym of Aphis taraxacicola (Börner, 1940). The nomen nudum Uroleucon (Uromelan) lehri Zaitzev, Lelej, Storozhenko & Kurzenko, 2006 is recognized as referring to Uroleucon (Uromelan) campanulae (Kalt...

The oviparous female and wingless male of Aphis verbasci from Poland and the United Kingdom are described and illustrated in detail for the first time, with notes on biology, distribution and host plants. 

Field surveys of soybean aphid, Aphis glycines Matsumura, and its natural enemies, as well as natural enemy exclosure experiments, were conducted during 2003 and 2004 in soybean fields near Langfang, China. In 2003, aphid density increased six-fold during 12 d in July from 66+/-12 per 10 plants to a seasonal peak of 401+/-79 per 10 plants. Aphid density remained high for another 10 d and declin...

The United States Department of Agriculture (USDA), Animal and Plant Health Inspection Service (APHIS), has prepared this decision document that is consistent with the requirements of the National Environmental Policy Act of 1969 (NEPA), as amended, the Council of Environmental Quality (CEQ) regulations implementing NEPA, and USDA departmental and APHIS NEPA-implementing regulations and procedu...
