Abstract

VITORIA, J.M. et al. Occurrence of mealybugs in "espinheira-santa" (Maytenus ilicifolia Mart. ex Reissek). Rev. bras. plantas med. [online]. 2013, vol.15, n.2, pp.176-179. ISSN 1516-0572.  http://dx.doi.org/10.1590/S1516-05722013000200002.

Maytenus ilicifolia is a medicinal species native to Brazil which has been cultivated to meet the growing market demand. Factors that interfere with the production, such as the incidence of pests and diseases, should be studied to ensure increased productivity. The aim of this study was to record the occurrence and the identification of mealybugs associated with 15 "espinheira-santa" (Maytenus ilicifolia) accessions from the Active Germplasm Bank of "Embrapa Clima Temperado" and "Instituto Federal Sul-rio-grandense". The quantity of infested plants in each accession was recorded and the species of infested mealybugs were identified in the laboratory. The number of infested plants varied among accessions. The identified mealybugs were Ceroplastes sp. and Saissetia oleae, family Coccidae. Of 10 infested accessions, 23 plants (11.3%) showed infestation with Ceroplastes sp., and only one (0.5%) with Saissetia oleae. Accession 133 showed the highest incidence of Ceroplastes sp. (33.3%), followed by accession 130 (25.0%). Accession 123 had the least amount of infested plants (4.8%). Saissetia oleae occurred in only one plant, belonging to accession 136 (5.6%).
