| 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 ... | 2007 | 17298687 |
| adaptation of indigenous larval parasitoids to tuta absoluta (lepidoptera: gelechiidae) in italy. | tuta absoluta (meyrick) (lepidoptera: gelechiidae) is a serious threat to tomato (solanum lycopersicum l.) crops in south america. in europe, after its first detection in spain in 2006, it rapidly spread through the mediterranean basin, reaching italy 2 yr later. the aim of our work was to find indigenous effective biological control agents and to evaluate their potential role in the control of larval populations of t. absoluta in controlled conditions. nine species of larval parasitoids emerged ... | 2012 | 22928311 |
