The Flat-Headed Apple-Tree Borer
Report discussing the flat-headed apple-tree borer, a common insect enemy of fruit trees in the United States. Topics discussed include its life cycle, distribution, appearance, and methods of controlling it.
We report the complete nucleotide sequence of a begomovirus infecting sweet potato in the Northeastern region of Argentina. Sequence comparisons indicated that the isolate under study has the highest nucleotide sequence identity (93.6 %) with Sweet potato leaf curl virus Puerto Rico. According to the current taxonomic criteria for bego- movirus classification the Argentinean isolate would corre- spond to a new strain of Sweet potato leaf curl virus.
