“…In Europe, the key parasitoid species of C . obstrictus are solitary idiobiont larval ectoparasitoids belonging to the hymenopteran family Pteromalidae: Trichomalus perfectus (Walker), Mesopolobus morys (Walker) and Stenomalina gracilis (Walker) . Of these three species, T .…”

“…Exclusion experiments are the most common approach [8,23] with or without camera observations, and also the level of parasitism can be measured by offering eggs or larvae that can be parasitized, e.g., [24]. For some pests, the natural enemies are already known and this information can be deduced from the literature, for example, for natural enemies of pests of cereal crops and oilseed rape, see [25,26]. Yet there remain many large gaps in our knowledge of natural enemy ecology and their effectiveness, which is not surprising given the diversity of species that can occur with crops ( Figure 1).…”

“…The failure to measure the impact in the adjacent field or wider landscape is one of the reasons why conservation biocontrol has not been widely adopted in field crops so far. Among the possible explanations is the lack of studies distinguishing between abundance and diversity of pest natural For some pests, the natural enemies are already known and this information can be deduced from the literature, for example, for natural enemies of pests of cereal crops and oilseed rape, see [25,26].

Invertebrates perform many vital functions in agricultural production, but many taxa are in decline, including pest natural enemies. Action is needed to increase their abundance if more sustainable agricultural systems are to be achieved. Conservation biological control (CBC) is a key component of integrated pest management yet has failed to be widely adopted in mainstream agriculture. Approaches to improving conservation biological control have been largely ad hoc. Two approaches are described to improve this process, one based upon pest natural enemy ecology and resource provision while the other focusses on the ecosystem service delivery using the QuESSA (Quantification of Ecological Services for Sustainable Agriculture) project as an example. In this project, a predictive scoring system was developed to show the potential of five seminatural habitat categories to provide biological control, from which predictive maps were generated for Europe. Actual biological control was measured in a series of case studies using sentinel systems (insect or seed prey), trade-offs between ecosystem services were explored, and heatmaps of biological control were generated. The overall conclusion from the QuESSA project was that results were context specific, indicating that more targeted approaches to CBC are needed. This may include designing new habitats or modifying existing habitats to support the types of natural enemies required for specific crops or pests.

“…Information on Conostigmus biology is very limited, but body size of their hosts (Syrphidae and boreid mecopterans) certainly allows the development of multiple parasitoid specimens (Dessart, 1980;Cooper and Dessart, 1975;Weems and Howard, 1954;Kamal, 1926;Ulber et al, 2010;Panis, 2008). These data suggest that differences in ceraphronoid body size is nutrition dependent thus body size polyphenism is most likely related to differences in cell number.…”

We revise the genus Conostigmus Dahlbom 1858 occurring in Madagascar, based on data from more specimens than were examined for the latest world revision of the genus. Our results yield new information about intraspecific variability and the nature of the atypical latitudinal diversity gradient observed in Ceraphronoidea. We also investigate cellular processes that underlie body size polyphenism, by utilizing the correspondence between epidermal cells and scutes, polygonal units of leather-like microsculpture. Our results reveal that body size polyphenism in Megaspilidae is most likely related to cell number and not cell size variation, and that cell size differs between epithelial fields of the head and that of the mesosoma.
