Figueroa, Christian C.; Simon, Jean Christophe; Le Gallic, Jean Francois L.E.; Prunier-Leterme, Nathalie; Briones, Lucia M.; Dedryver, Charles Antoine; Niemeyer, Hermann M. (2004)Five microsatellite loci were used to study the genetic variability and population structure of Sitobion avenae (Hemiptera: Aphididae) on some of its host plants. Individuals were collected in Chile from different cultivated ...

Loayza-Muro, Raúl; Figueroa, Christian C.; Niemeyer, Hermann M. (2000)Hydroxamic acids (Hx) are wheat secondary metabolites conferring resistance for cereals against aphids. The activity of five enzymatic systems were evaluated in the aphid Sitobion avenae reared on the high-Hx wheat cultivar ...

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 ...

Figueroa, Christian; Niemeyer, Hermann; Cabrera-Brandt, Marco; Briones, Lucia; Lavandero, Blas; Zúñiga Reinoso, Alvaro; Ramírez, Claudio (Wiley, 2018-07)The diversity and distribution of the genetic variation in forest phytophagous insect populations can be highly sensitive to forest fragmentation. This should be particularly evident for monophagous insects living on ...

Figueroa, Christian C.; Simon, Jean Christophe; Le Gallic, Jean Francois; Niemeyer, Hermann M. (1999)A set of molecular markers to differentiate the aphid (Hemiptera: Aphidoidea) species Sitobion avenae (Fabricius) from Sitobion fragariae (Walker), is presented. These markers correspond to (1) a region of the mitochondrial ...

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 ...
