Host discrimination by Elasmus schmitti

The ability to discriminate parasitized and non-parasitized hosts allows the parasitoids to avoid intraspecific and often interspecific competition. In 2005-2009, the incidence of mixed infestation of Polistes nimpha (Christ) colonies by parasitoids Elasmus schmitti Ruschka (Hymenoptera, Eulophidae)...

Description
Summary:The ability to discriminate parasitized and non-parasitized hosts allows the parasitoids to avoid intraspecific and often interspecific competition. In 2005-2009, the incidence of mixed infestation of Polistes nimpha (Christ) colonies by parasitoids Elasmus schmitti Ruschka (Hymenoptera, Eulophidae) and Latibulus argiolus (Rossi) (Hymenoptera, Ichneumonidae) was analyzed. In settlements of different types, the frequencies of mixed infestation deviated from the values expected in case of random distribution. The presence or absence of discrimination ability cannot be confirmed unequivocally based on our material. The data obtained are discussed in relation to the biological features of parasitoids.
