BANOS JUAREZ, Andrés; PEREZ DE LA CRUZ, Manuel; SANCHEZ SOTO, Saúl  and  CAPELLO GARCIA, Silvia. Population dynamics of Xyleborus volvulus (F.) (Coleoptera: Curculionidae) in localities of Tabasco, Mexico. Acta Zool. Mex [online]. 2012, vol.28, n.3, pp.540-549. ISSN 2448-8445.

The aim of this study is to show the population dynamics of Xyleborus volvulus in six localities of Tabasco, Mexico. The trapping methods used were alcohol traps, light traps and directly capture from their host plants. The total number of specimens collected was 4 600, using the three methods of collection. Most organisms were collected using alcohol traps 2 927, followed by light traps with 1 595 and finally from their host plants with 78. The fluctuation of X. volvulus showed two population peaks in all the localities studied, one at the beginning (January-April) and another one towards the end (September, November and December) of study period, which, in most cases, coincides with those periods of rain in the area. Also, it was determined that this species is present throughout the year but with low populations.
