integration of molecular, ecological, morphological and endosymbiont data for species delimitation within the pnigalio soemius complex (hymenoptera: eulophidae).integrative taxonomy is a recently developed approach that uses multiple lines of evidence such as molecular, morphological, ecological and geographical data to test species limits, and it stands as one of the most promising approaches to species delimitation in taxonomically difficult groups. the pnigalio soemius complex (hymenoptera: eulophidae) represents an interesting taxonomical and ecological study case, as it is characterized by a lack of informative morphological characters, deep mitoch ...201222268975
rickettsia symbionts cause parthenogenetic reproduction in the parasitoid wasp pnigalio soemius (hymenoptera: eulophidae).bacteria in the genus rickettsia are intracellular symbionts of disparate groups of organisms. some rickettsia strains infect vertebrate animals and plants, where they cause diseases, but most strains are vertically inherited symbionts of invertebrates. in insects rickettsia symbionts are known to have diverse effects on hosts ranging from influencing host fitness to manipulating reproduction. here we provide evidence that a rickettsia symbiont causes thelytokous parthenogenesis (in which mother ...201020173065
phenotypic plasticity of pigmentation and morphometric traits in pnigalio soemius (hymenoptera: eulophidae).species of the genus pnigalio schrank are ectoparasitoids on several pest insects. most species are polyphagous parasitoids of lepidopteran and dipteran leafminers. despite their potential economic importance, information on intraspecific phenotypic variability is insufficient. pnigalio soemius (walker) was reared at five different temperatures (10, 15, 20, 25, 30 degrees c) on mature larvae of one of its natural hosts, cosmopterix pulchrimella chambers (lepidoptera: cosmopterigidae), to investi ...200717298687
