Apterous adult Myzus persicae (Sulz.) of a glasshouse strain differed greatly in their ability to colonise sugar-beet according to the plant on which they and their forebears were cultured. Those from Chinese cabbage (Brassica pekinensis) settled least readily on beet, whilst aphids from broad beans (Vicia faba) produced larger populations than those cultured on by: This book is a follow up of my earlier book that analyses opportunities and challenges for sugar beet cultivation in Kenya. This book covers an in-depth assessment of the biophysical land suitability for sugar beet growing in Kenya, and also an in-depth assessment of the socio-economic prospects and challenges for sugar beet : Nicodemus Mandere.
Introduction. Myzus persicae (Sulz.) is an important pest of sugar beet Beta vulgaris L. as a vector of two viruses, beet yellows virus (BYV) and beet mild yellowing virus (BMYV), which can cause up to 50% and 35% loss of yield, respectively (Smith & Hallsworth ).Sugar beet is infected by virus yellows carried into the crop by alate aphids (primary infection), predominantly My. persicae Cited by: Previous research suggests that extant potato cultivars offer little promise as sources of useful aphid resistance. However, few prior studies have critically measured the effects of host cultivar on aphid age-dependent life table statistics or related these measures to field performance. Therefore, a comprehensive field and greenhouse study was undertaken to assess 49 commercial potato Cited by:
The following is almost entirely from the authors' summary. The leaf-by-leaf distributions of free infestations of viviparae of Myzus persicae (Sulz.) and Aphis fabae Scop. were recorded on sugar-beet plants and spindle bushes (Euonymus europaeus) in pots in the greenhouse, and the distributions of the various seasonal forms of A. fabae were recorded on the same plants growing naturally out of Cited by: Key words: Beet yellows closterovirus, beet mild yellowing luteovirus, green peach aphid, Myzus persicae, sugar beet, Beta vulgaris, virus spread, predators, coccinellids, mathematical model Introduction 57 Virus yellows is a globally important disease of sugar-beet.

Sugar beet-Aphid. Black bean aphid (Aphis fabae) Green peach aphid (Myzus persicae) Pest description and crop damage The black bean aphid is a dark-bodied aphid, inch long, that sporadically reaches damaging levels, most often late in the season. Infestations usually occur as scattered hot spots or along edges rather than uniformly across the entire field.

sugar beet and this might account for the greater alate production. Infection of sugar beet with beet yellows virus did not increase alate production by My.
persi-cae. A deterministic model showed that the probability of an alate My. persicae migrating from sugar beet and recolonizing sugar beet the following year would, at best, be only 1 Cited by: Monitoring is important in field crops, but M.
persicae transmits viruses of crops such as sugar beet and potato at low densities, and is therefore difficult to detect on the crop before the damage is done.
Suction and yellow traps are the most efficient way to detect first migration of winged aphids into the crop. Myzus persicae (Sulzer) (Coutin R. / OPIE) Colony The inferior face of a beet leaf.
Myzus persicae (Sulzer) (Coutin R. / OPIE) Colony on tomato Aphids situated on the underside of leaves excrete honeydew, to which exuviae stick.
This provides evidence for the presence of this pest. Myzus persicae (Sulzer) (Coutin R. / OPIE). Myzus persicae is a major pest on its summer hosts including potatoes, sugar beet, lettuce, brassicas and legumes, mainly because it transmits a number of important plant viruses.
Whilst Myzus persicae is a polyphagous generalist, the subspecies Myzus persicae nicotianae is a tobacco specialist. Other aphids on same host: Primary hosts.

The leaf‐by‐leaf distributions of free infestations of viviparous Myzus persicae (Sulz.) and Aphis fabae Scop, were recorded on sugar‐beet plants and spindle bushes in pots in the greenhouse, and the distributions of the various seasonal forms of A.
fabae were recorded on the same plants growing naturally outdoors. The aphid distributions were related to the ages of the leaves estimated Cited by: The feeding habit of the aphid, Myzus persicae, that transmits the virus of the beet yellows disease of sugar beet, was studied by examining the course of the insect’s mouth parts in sugar beet leaves.
Of the penetrations that were identified by the saliva sheaths left by the insects in the leaf tissues, 50 per cent terminated in the phloem tissue, the others in the mesophyll or other. The green peach aphid, Myzus persicae (Sulzer), is found throughout the world, including all areas of North America, where it is viewed as a pest principally due to its ability to transmit plant viruses.
