The yellow flag, Iris pseudacorus L. (Iridaceae) is an emergent perennial wetland plant native to the Palearctic region and has been dispersed worldwide as an ornamental plant. In the introduced range, it is highly invasive in natural and artificial waterbodies. Currently, this species is difficult to manage and continues to spread, causing signifi...

Exotic water primroses (Ludwigia spp.) are aggressive invaders in aquatic ecosystems worldwide. To date, management of exotic Ludwigia spp. has been limited to physical and chemical control methods. Biological control provides an alternative approach for the management of invasive Ludwigia spp. but little is known regarding the natural enemies of t...

Exotic water primroses are aggressive invaders in both aquatic and riparian ecosystems worldwide. Water primrose [Ludwigia hexapetala (Hook. & Arn.) Zardini, Gu & P. H. Raven], floating primrose-willow [Ludwigia peploides (Kunth) P. H. Raven subsp. peploides], floating primrose-willow [Ludwigia peploides (Kunth) P. H. Raven subsp. montevidensis (Sp...

Environmental education seeks to foster an appreciation for nature and the impact of humans on it while introducing citizens to scientific thinking. Biological invasions affect different aspects of life on earth and mandate urgent management actions. Education and public awareness are strongly recommended for successful prevention and management of...

Several components of classical biological control (CBC) programmes are necessary to assess the success of the management strategy (e.g., post-release monitoring) and also help prevent reintroductions or resurgences of invasive species (e.g., public awareness). Water hyacinth, Pontederia (= Eichhornia) crassipes (Mart.) Solms (Pontederiaceae) is an...

In the search for specific natural enemies to control two invasive aquatic plants (IAP) from South America, Ludwigia grandiflora subsp. hexapetala (Onagraceae) and Myriophyllum aquaticum (Haloragaceae), taxonomic challenges associated with two Lysathia Bechyné, 1959 (Chrysomelidae; Alticini) species had to be resolved. Lysathia flavipes (Boheman, 1...

The Avellaneda and Quilmes coastal biocorridor is part of one of the areas with the greatest diversity of plant and animal species in the Buenos Aires Metropolitan Area (AMBA). There are two main factors that can explain these high levels of biodiversity: its geographical location and its environmental heterogeneity. The corridor is geographically...

Las rutas migratorias dieron lugar al transporte de especies fuera de su área nativa, lo que generó uno de los procesos ecológicos más impactantes: la expansión de plantas exóticas invasoras (EEI) en detrimento de las nativas. Esta transformación afecta los ecosistemas, perturba el bienestar humano y es la segunda causa de la disminución de la bio...

Cactoblastis cactorum (Berg) (Lepidoptera: Pyralidae), the cactus moth, is native to South America with a widespread distribution in Argentina. The larvae consume the interior of Opuntia spp. (Cactaceae) plants. The moth was used as a biocontrol agent against invasive non-native Opuntia spp. in many countries around the world. The cactus moth arriv...

In the search for insects as biological control agents for the water primrose, the delphacid Pissonotus paraguayensis (Delphacidae) was found on Ludwigia grandiflora subsp. hexapetala (Onagraceae) in a wetland of Central East Argentina. The morphology of the unknown females (brachypterous and macropterous) and immature stages are described and illu...

Insect outbreaks are a common multicausal population phenomenon that is characterised by a fast growth of the population, followed by an equally sudden collapse in a relatively short period in the manner of an excitable system. If the outbreaking insect is herbivorous or attacks trees or plants as a part of its life cycle, this phenomenon causes a...

South American invasive plants in the genus Ludwigia (Onagraceae) degrade many riparian and aquatic ecosystems worldwide. Biological control may aid in the management of these exotic weeds, but data on the host specificity of Ludwigia natural enemies is limited. The biology and host range of Sudauleutes bosqi Hustache (Coleoptera: Curculionidae), a...

Resumen La Ley de Educación Ambiental, recientemente promulgada, tiene como objetivo principal promover la educación ambiental e incorporar los nuevos paradigmas de la sostenibilidad a los ámbitos de la educación formal y no formal. Las especies invasoras causan daño en ambientes naturales, agrícolas y urbanos. Es tarea de la comunidad docente apoy...

The host range of the thrips Liothrips ludwigi was investigated using single- and multi-generational no-choice nymphal development and oviposition tests. Development, oviposition, and egg viability were quantified when L. ludwigi were fed three exotic Ludwigia species and seven USA native plant species. Liothrips ludwigi completed development and o...

Cactoblastis cactorum's unintended arrival to Florida and its expansion in North America represent a threat to Opuntia‐based agriculture and natural ecosystems in the United States and Mexico. Apanteles opuntiarum attacks C. cactorum and is a potential biocontrol agent due to its specificity, wide distribution and occurrence. Laboratory rearing met...

Although Argentina treasures a vast area covered by wetlands, many of them are negatively impacted by the presence of Alien Invasive Plants. Iris pseudacorus L. (Iridaceae) (Yellow Flag) is an alien invasive weed that is native to Europe, northern Africa and western Asia, and introduced around the world mainly for its ornamental value. In the intro...
