Host Plant Specialization in the Sugarcane Aphid Melanaphis sacchari
Most aphids are highly specialized on one or two related plant species and generalist species often include sympatric populations adapted to different host plants. Our aim was to test the hypothesis of the existence of host specialized lineages of the aphid Melanaphis sacchari in Reunion Island. To this end, we investigated the genetic diversity of the aphid and its association with host plants...

متن کاملPlant immunity in plant–aphid interactions
Aphids are economically important pests that cause extensive feeding damage and transmit viruses. While some species have a broad host range and cause damage to a variety of crops, others are restricted to only closely related plant species. While probing and feeding aphids secrete saliva, containing effectors, into their hosts to manipulate host cell processes and promote infestation. Aphid ef...
متن کاملThe impact of host plant on the abundance and function of symbiotic bacteria in an aphid.
The black-bean aphid Aphis fabae bears populations of coccoid symbiotic bacteria Buchnera spp. at 2.0-3.2 x 10(7)cells mg(-1)aphid mass and rod-shaped secondary symbionts of uncertain taxonomic affiliation at 0.1-0.6 x 10(7)cells mg(-1)aphid mass. Buchnera provides essential amino acids, supplementing the poor supply in the aphid diet of plant phloem sap. Comparison of the performance of A. fab...
متن کاملRole of Pea Enation Mosaic Virus Coat Protein in the Host Plant and Aphid Vector
Understanding the molecular mechanisms involved in plant virus-vector interactions is essential for the development of effective control measures for aphid-vectored epidemic plant diseases. The coat proteins (CP) are the main component of the viral capsids, and they are implicated in practically every stage of the viral infection cycle. Pea enation mosaic virus 1 (PEMV1, Enamovirus, Luteovirida...
