Última Is autotoxicity responsible for inhibition growth of new conspecific seedlings under the canopy of the invasive Acacia dealbata Link? Gayana Botánica Aguilera,Narciso; Guedes,Lubia M.; Becerra,José; González,Luis. ABSTRACT Autotoxicity is a particular form of allelopathy and is suspected to be responsible for regulating intraspecific competition under the Acacia dealbata Link (Fabaceae) canopy. Was established a bioassay with controlled conditions following the natural patterns of plant material accumulation under the A. dealbata canopy to determine the effects of chemical compounds released by leaves, bark, flowers and pods of the invasive species on germination and early growth of conspecific seedlings. Morphological changes caused by A. dealbata plant parts in roots of A. dealbata seedlings grown in natural and controlled conditions were evaluated with scanning electron microscopy. The composition and behavior of the phytotoxicity of litter under the A. dealbata...

Bras. entomol. Garcete-Barrett,Bolívar R.; Morales,Mírian N.; Hauser,Martin; Smit,John T.; González,Luis; López,María Bernarda Ramírez De; Arias,Osmar; Adorno,Marcial; Sormanti,Gerald; Mereles,Adriana. Abstract Eumerus Meigen, 1823 is a very speciose genus of flower flies from the Eastern Hemisphere. Several reports of introduced species of this genus in the Americas have been recorded since early in the twentieth century, with a present list of six species recorded to date from the Americas and the US territory of Hawaii. In this paper we give new geographical records for the African-native species Eumerus obliquus (Fabricius, 1805), which reflect the expansion of this fly through Brazil and Paraguay along the last twenty years. At the same time, we report a second species from Paraguay, Eumerus aurifrons (Wiedemann, 1824), being this the first Western Hemisphere record for this Asian-native species. We finally provide an identification key to all of... Tipo: Info:eu-repo/semantics/article Palavras-chave: Hover flies; Identification key; Invasive species; Pest insects.
