ZACHRISSON, Bruno; HERRERA-VASQUEZ, José Ángel  e  BERNAL, Juan. Hosts plants of Bemisia tabaci (Gennadius) (Hemíptera: Aleyrodidae), in adjacent areas of the tomato crop, in the east region of Panama. Idesia [online]. 2017, vol.35, n.1, pp.119-222. ISSN 0718-3429.  http://dx.doi.org/10.4067/S0718-34292017005000019.

The hosts plants of eggs and nymphs of Bemisia tabaci (Gennadius), totaled 16 species grouped in 11 families, which were sampled and collected in adjacent areas to the plots of tomato production. This study was conducted in the locality of "La Mesa de San Martín", in the East region of Panama, through quarterly assessments carried out between May of 2013 and June 2014. Is per-formed random sampling that consisted of 15 points of 1 m2, assessing the numbers of eggs and the nymphs of this insect vector of begomovirus, in five leaves or leaflets in the upper, medium and lower level of the plants. The total area sampled by leaf or leaflet of the host plant was 1,000 cm2. The greater incidence of eggs and nymphs of B. tabaci is recorded in Guazuma ulmifolia Lam., Jatropha gossypifolia L., Solanum torvum Sw., Jatropha urens L. and Physalis angulata L. Discussed the role of the host plants of B. tabaci in the begomovirus spread and the management of this biotic interaction in the areas of tomato production.
