Notes: [Ocorrencia de Selenaspidus articulatus (Morgan) (Hemiptera, Diaspididae) e do predador Pentilia egena (Mulsant) (Coleoptera, Coccinelidae) em Myrtus communis L. (Myrtaceae), em Pinheiral, RJ.] The evaluations were conducted weekly in the vegetative and blooming/fructification phases in four quadrants (N, S, E, W) of the plant. 2,230 specimens of S. articulatus were collected in the vegetative phase and 1,006 in the blooming/fructification, therefore, 59,8% adults. From the total of 965 P. egena, 416 were immatures and 549 adults. The main conclusions are: (I) M. communis may be useful as plant bait; (2) this plant may be cultivated or not around the crops of economic importance because it may function as a reservoir of the pest or of its natural enemies; (3) the relationship of predator/prey/plant quadrant/phenology phases was, respectively, 1.14:1.0 and 1.0:1,08 in north and east quadrant; while in the south and west quadrants it was 1.0:2.26 and 1.0:2.80; and, (4) the predation of S. articulatus by P. egena was, on average, 1.0-2.8 nymphs and 1.66-4.44 adults (in vegetative phases) and 1.0-3.76 and 1.0-3.98 (in blooming/ fructification) with significant differences at P 0.01.
