Barros Parada, Wilson; Bergmann, Jan; Curkovic Sekul, Tomislav; Espinosa, Cristian; Fuentes-Contreras, Eduardo; Guajardo, Jorge; Herrera, Heidy; Morales, Sebastián; Queiroz, Abel F. O.; Vidal, Álvaro (Springer, 2020)Leucoptera sinuellais a leaf-miner moth present in several regions in the world, which has been recently introduced into Chile. The larvae feed exclusively on the leaves of poplar and willow trees, and the damage caused ...

Daza-Bustamante, Pauline; Fuentes-Contreras, Eduardo; Niemeyer, Hermann M. (Czech Academy of Sciences, 2003)Aphidius ervi Haliday is a parasitoid of natural populations of both Acyrthosiphon pisum (Harris) on alfalfa and Sitobion avenae (Fabricius) on wheat in Chile. In this study the performance of the aphid parasitoid on both ...

Lagos, Nelson A.; Fuentes-Contreras, Eduardo; Bozinovic, Francisco; Niemeyer, Hermann M. (2001)The effects of parasitisation by Aphidius ervi on the thermoregulatory behaviour of the pea aphid Acyrtosiphon pisum were studied in alfalfa fields and in an experimental thermal gradient. In the field, mummies were found ...

Rodríguez, Luis C.; Fuentes-Contreras, Eduardo; Niemeyer, Hermann M. (Czech Academy of Sciences, 2002)The aphid parasitoid Aphidius ervi was collected and subsequently reared on Sitobion avenae on wheat or Acyrthosiphon pisum on alfalfa. Parasitoids from both origins were exposed in an olfactometer to alfalfa or wheat ...

Fuentes-Contreras, Eduardo; Niemeyer, Hermann M. (2000)The influence of wheat (Triticum aestivum L.) resistance, the parasitoid Aphidius rhopalosiphi De Stephani-Perez (Hymenoptera: Braconidae) and the entomopathogenic fungus Pandora neoaphidis (Remaudiere et Hennebert) Humber ...

Castañeda, Luis E.; Figueroa, Christian C.; Fuentes-Contreras, Eduardo; Niemeyer, Hermann M.; Nespolo, Roberto F. (2009)Herbivorous insects have developed mechanisms to cope with plant barriers, including enzymatic systems to detoxify plant allelochemicals. Detoxification systems may be induced when insects are feeding on plants with ...

Gonzáles, Wilfredo L.; Fuentes-Contreras, Eduardo; Niemeyer, Hermann M. (2002)Competition between phytophagous insects could be mediated by differential impact of natural enemies or by induced changes in host plant quality. The interaction between the aphids Sipha flava and Rhopalosiphum maidis on ...

Quiroz, Andrés; Fuentes-Contreras, Eduardo; Ramírez, Claudio C.; Russell, Graeme B.; Niemeyer, Hermann M. (Kluwer Academic/Plenum Publishers, 1999)Extractable metabolites from leaves (EM) and volatiles released from six Nothofagus species were analyzed by TLC and GC-MS, respectively. Aphids of the genus Neuquenaphis, closely associated to Nothofagus, were sampled on ...
-
Fuentes-Contreras, Eduardo; Pell, Judith K.; Niemeyer, Hermann M. (1998)Host-plant resistance can affect herbivorous insects and their natural enemies such as parasitoids and entomopathogenic fungi. This tritrophic effect acts on interspecific interactions between the two groups of natural ...

Castañeda, Luis E.; Figueroa, Christian C.; Fuentes-Contreras, Eduardo; Niemeyer, Hermann M.; Nespolo, Roberto F. (2010)'Superclones' are predominant and time-persistent genotypes, exhibiting constant fitness across different environments. However, causes of this ecological success are still unknown. Therefore, we studied the physiological ...
