“…A significant number of infertile achenes, in many cases by parasitism, was identified in the species studied. Previously, parasitism was pointed out in F. thurifera by Diptera females that oviposit on the flowers and their larvae develop in the ovaries (Frías 1985) and in F. cernua by Diptera and Coleoptera larvae (Richerson & Boldt 1995;Valencia Díaz & Montaña 2003). Achenes with abortive embryos have also been informed in F. cernua (Valencia Díaz & Montaña 2003, 2005 and other Asteraceae (e.g.…”

Our objective was to study reproductive biology, seed germination and regeneration, through morphoanatomical and field observations and controlled experiments, to assess reproductive strategies in six rare Flourensia endemic to Central Argentina (F. campestris, F. hirta, F. leptopoda, F. niederleinii, F. oolepis, F. tortuosa). Structure of capitula, flowers, and achenes was described. Capitula were visited by a variety of insects. Achenes required 30-45 days to mature. Fruit set varied significantly among species. Flourensia campestris and F. oolepis were self-incompatible. Seed viability decreased after 19 months and was lost after 32 months. Flourensia oolepis and F. campestris had the highest germination percentages (>60%); the addition of gibberellic acid in 2-months old seeds did not influence germination. The remaining species had lower germination percentages (<30%). All species had xylopodia that were root and stem modifications. Burned individuals of F. campestris actively regenerated from underground buds of xylopodia, being suitable for restoration of degraded or burned areas. Flourensia campestris and F. oolepis had better reproductive success, but the remainder species can be considered at risk. Strategies should be implemented to protect them, such as to preserve its habitat together with attempts to increase their population sizes and maintain their pollinators.

“…Adult populations emerge during spring and summer (Porter 1929, Aljaro et al 1984. Neotropical Tephritinae morphology of immature stages, with only a few exceptions, are poorly known (Frías 1985, Gandolfo & Hernández 1999, Steck & Wharton 1986. This paper describes the morphology of three instar larvae and pupae of R. limbata, compared other Tephritinae and Trypetidae morphology, discussed in an evolutionary biology framework.…”

Neotropical Entomology 37(5): 536-545 (2008) Morfologia dos Estados Imaturos da Espécie de Mosca das Frutas Neotropical não Frugívoradobras da cutícula, as margens da abertura oral, o esqueleto cefalofaríngeo, os espiráculos anterior e posterior e os lóbulos anais das larvas de primeiro, segundo, terceiro estádios e da pupa. O esqueleto cefalofaríngeo é altamente esclerotizado e apresenta um orifício ou abertura na cornua ventral, característica essa que parece ser plesiomórfi ca em R. limbata e outras espécies neotropicais. Os espiráculos anteriores estão ausentes nas larvas de primeiro estádio. Nas larvas de segundo e terceiro estádios são desenvolvida formando cinco túbulos curtos dispostos em fi leira única. Nas larvas de primeiro e segundo estádios, as aberturas dos espiráculos têm cerdas únicas; nas larvas de terceiro estádio não há cerdas. Essa última característica parece decorrer de uma atraso no desenvolvimento (neotenia) da larva de R. limbata, quando comparada a outras espécies neotropicais e neárticas.PALAVRAS-CHAVE: Adaptação, neotenia, caráter plesiomórfi co, apomórfi co ABSTRACT -Rachiptera limbata Bigot develops on Baccharis linearis (R. et Pav.) in the areas around Santiago, Chile. The larvae feed on stem tissues and secrete a liquid that hardens to form a protective feeding and pupation chamber. The immature stages of Neotropical species of Tephritinae are poorly known. In this paper, the morphology of the immature stages of R. limbata are described and compared, in a phylogenetic context, with other Tephritinae species. Antennomaxillary complex, pads, oral ridge, cephalopharyngeal skeleton, anterior and posterior spiracles and anal lobes of fi rst-, second-, third-instar larvae and pupae were studied with optical and scanning electron microscopy. The cephalopharyngeal skeleton is darkly sclerotized and shows an opening or window in the ventral cornua. This trait seems to be plesiomorphic in R. limbata and in other Neotropical species. First-instar larvae anterior spiracles are absent; whereas in second and third instars spiracles are developed as a row of fi ve short tubules. In fi rst-and second-instar larvae, the posterior spiracular slit has only a single hair per bundle; whereas third-instar larvae lack hairs. This last trait seems to be consequence of a larval development delay and an apomorphic trait in R. limbata, compared to other Neotropical and Neartical species.
