SANTOS, Janaína Pereira dos et al. Parasitoids of leafmining lepidoptera in spontaneous growth plants in an organic citrus orchard in montenegro, RS, Brazil. Rev. Bras. Frutic. [online]. 2007, vol.29, n.1, pp.80-84. ISSN 1806-9967.

This work aimed to check if Phyllocnistis citrella attacks spontaneous growth plants present in an organic citrus orchard, to identify in these plants other leafmining Lepidoptera and its parasitoids, and to verify if the parasitoids species are the same ones reported for P. citrella. The work was conducted in Montenegro, RS, in an organic orchard of the hybrid 'Murcott' (Citrus sinensis x C. reticulata). Samplings were taken every other week, from May 2003 to May 2004, with a ring of 0.28 m2 being randomly thrown in the lines and interlines of 30 trees. All the plants with mines inside of the ring were collected. The screening of the material was made in laboratory. Eleven species of leafmining Lepidoptera and 12 species of microhymenopteran parasitoids were found. Some genera identified that this study had been already reported in several regions of the world with parasitizing species P. citrella, such as Chrysocharis, Closterocerus, Sympiesis (Hymenoptera: Eulophidae) and Bracon (Hymenoptera: Braconidae).

Keywords : Phyllocnistis citrella; biological control; citrus orchards.
