Leveduras associadas a Spermologus rufus Boheman (Coleoptera: Curculionidae)

Abstract

Yeasts Associated with Spermologus rufus Boheman (Coleoptera: Curculionidae) ABSTRACT-Larvae and adults of Spermologus rufus Boheman can cause severe damage to seeds of Brazilian pine, Araucaria angustifolia. In this study, yeasts were isolated from seeds of A. angustifolia and from the digestive tract of S. rufus to verify their similarity and determine the existence of feeding sites in order to elaborate an artificial diet for this insect. Pichia spp. were found in seeds and Pichia spp. and P. stipitis Pignal in the digestive tract of S. rufus. The low variability among observed microorganisms suggests a food preference, which can facilitate the elaboration of artificial diets.

“…were taken from Phytelephas flowers (Palmae) (Lyal, personal observation), whereas Franz (2006) wrote: "Crownshafts of all genera of the Iriarteinae (subtribe of Arecaceae) contain within the outer one or two leaf sheaths a reddish mucilaginous substance which may be similar to that found in the roots, and may be a protective excretion against insects. The larvae of Spermologus Schoenherr, in contrast, are seed feeders, S. rufus Boheman of Araucaria angustifolia (Araucariaceae) (Barreto et al 1998(Barreto et al , 1999Barreto & Anjos 2002), S. rolliniae Marshall of Rollinia (Annonaceae), S. funereus Pascoe of Annona crassiflora Mart. Trypetes politus Pascoe has been collected from the inflorescence of the palm Socratea hecatonan dra in Colombia (Henderson 1990).…”
