Semiochemicals and Tritrophic Interaction Among Leguminous Plants, Aphids and Coccinellid Predators [PDF]
Chemical communication between the leguminous plants (cowpea, white bean and broad bean), aphids (Aphis gossypii, Aphis. fabae and Myzus persicae) and the coccinellidspecies (Coccinella. undecimpunctata L., Coccinella. Septempunctata L.

Flight activity of aphids in Serbia: investigation by water traps placed in sugar beet fields
Plant viruses, and aphids as their vectors, are limiting factors in sugar beet production. Viral plant diseases are currently impossible to treat but knowing the flight patterns of aphids can help in reducing the number of potential virus vectors ...

The morphological variation of Myzus persicae (Hemiptera: Aphididae) from peach and tobacco in Serbia and Montenegro [PDF]
Multivariate morphometric analysis was used to compare nine characteristics of 47 populations of Myzus persicae (Sulzer) originating from two host-plants, peach and tobacco, from 13 localities in 2004 and 34 localities in 2005, in Serbia and Montenegro ...

Transmission of Tobacco Mosaic Virus by Myzus persicae
It is well known that many plant viruses can be transmitted by aphids, but the highly infectious tobacco mosaic virus (TMV) seems to have no aphid vector. Only Hoggan (1934) reported a very low level of transmission which, however, has not been substantiated (Orlob, 1963; Pirone, 1969).

A mutation in amino acid permease AAP6 reduces the amino acid content of the Arabidopsis sieve elements but leaves aphid herbivores unaffected [PDF]
The aim of this study was to investigate the role of the amino acid permease gene AAP6 in regulating phloem amino acid composition and then to determine the effects of this altered diet on aphid performance.

Determination of Resistance Levels of Myzus persicae (Sulzer) by Biochemical Methods [PDF]
Peach/potato aphid Myzus persicae (Sulzer) has developed three mechanisms of resistance: overproduction of one or two closely related carboxylesterases (E4 and FE4), production of modified acetylcholinesterase (MACE and knockdown resistance ...

Micro-evolutionary change in relation to insecticide resistance in the peach-potato aphid, Myzus persicae [PDF]
2. Asexual organisms rely on mutation whereas sexual organisms combine mutation with recombination. 3. Few organisms provide examples of species that are both sexual and asexual, but aphids do. 4.
