SANTOS, Dierlei dos; SIQUEIRA, Dalmo Lopes de  e  PICANCO, Marcelo Coutinho. Population dynamics of sharpshooters species transmitter of citrus variegated chlorosis (CVC) in Viçosa-MG. Rev. Bras. Frutic. [online]. 2005, vol.27, n.2, pp.211-214. ISSN 1806-9967.  https://doi.org/10.1590/S0100-29452005000200007.

The objectives of this work were to evaluate the presence and the population dynamics of Citrus CVC transmitter sharpshooters along the year in the municipality of Viçosa- MG. The sharpshooter populations were monitored in the period of August 2003 to July 2004 using yellow adhesive traps and entomologic nets. During this period 2966 sharpshooters were captured and identified. Among eleven species known as CVC transmitters, nine were found in the region. The three most expressive species in number found were Bucephalogonia xanthophis (36,6% captured in entomological net and 34,7% in the trap), Dilobopterus costalimai (9,9% captured in entomological net and 11,3% in the trap) and Acrogonia citrina (6,8% captured in entomological net and 7,4% in the trap). The largest incidence of sharpshooters occurred in November (378 insects), with the population reaching the pick in the first fifteen days of the month (292 insects). There was not significant difference among the medium number of sharpshooters collected in the interior and in the periphery of the area.
