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 کاملCategorizing sugarcane cultivar resistance to the sugarcane aphid and yellow sugarcane aphid (Hemiptera: Aphididae).
Sugarcane (Saccharum spp.) in Louisiana is colonized by two aphid species, the sugarcane aphid, Melanaphis sacchari (Zehntner), and the yellow sugarcane aphid, Sipha flava (Forbes) (Hemiptera: Aphididae). The main problem associated with M. sacchari is transmission of sugarcane yellow leaf virus, a casual agent of yellow leaf disease whose absence has been added to certification standards for m...
متن کاملEradicating Sugarcane Yellow Leaf Virus in Sugarcane Variety N32 through Tissue Culture
Yellow Leaf Syndrome of sugarcane is caused by Sugarcane Yellow Leaf Virus (SCYLV) and/or Sugarcane Yellows Phytoplasma (SCYP). Using tissue blot immunoassay to determine the presence of SCYLV, leaf samples of sugarcane variety N32 taken from a propagation plot at Mount Edgecombe all tested positive. In this study, two methods of tissue culture were used in an attempt to eradicate SCYLV from N3...
متن کاملThe P0 gene of Sugarcane yellow leaf virus encodes an RNA silencing suppressor with unique activities.
The Sugarcane yellow leaf virus (SCYLV) P0, a member of the highly heterologous proteins of poleroviruses, is a suppressor of posttranscriptional gene silencing (PTGS) and has additional activities not seen in other P0 proteins. The P0 protein in previously tested poleroviruses (Beet western yellows virus and Cucurbit aphid-borne yellows virus), suppresses local, but not systemic, PTGS induced ...
متن کاملTransmission of sugarcane white leaf phytoplasma by Yamatotettix flavovittatus, a new leafhopper vector.
Sugarcane white leaf disease is caused by plant pathogenic phytoplasmas that are transmitted to the plant by the leafhopper Matsumuratettix hiroglyphicus (Matsumura). To determine whether there are other insect vectors that transmit this disease pathogen, leafhopper species in sugarcane, Saccharum officinarum L., fields in northeastern Thailand were monitored by using light traps. Sixty-nine le...
