Manipulation of araneid spider web architecture by the polysphinctine parasitoid Zatypota picticollis (Hymenoptera: Ichneumonidae: Pimplinae)

Abstract: We found that the koinobiont ectoparasitoid wasp Zatypota picticollis is exclusively associated with three orb weaving spiders Cyclosa conica, Mangora acalypha and Zilla diodia from the family Araneidae. Under the influence of the parasitoid's final instar larva the spiders built a specific web architecture, which differed considerably from the capturing orb web. Manipulated webs of C. conica and M. acalypha lacked the spiral, stabilimentum and central hub, and the radials were reduced in number. The manipulat… Show more

“…Knowledge on the life history of polysphinctine wasps is very sparse and is mostly restricted to information on time from egg to adulthood or the duration of the pupal stage (e.g. Nielsen 1923;Fincke et al 1990;Tanaka 2007;Fritzén, 2010Fritzén, , 2014Korenko et al 2014Korenko et al , 2015. The present study provides complex information on the life history and phenology of the polysphinctine spider parasitoid Z. percontatoria in climatic conditions in Central Europe using laboratory, semi-field and field data.…”

“…Similar behavior was observed by Day (1981) for Pompilus cinereus (Fabricius). Most known behavioral manipulation interactions induced by parasitoid wasps target web building spiders, with behavior modification tending to include the construction of modified webs which may exhibit a tridimensional tangle structure, absence of sticky spirals, central hub and stabilimentum, reduced number of radial lines and refuges that protect the cocoon and increase parasitoid survival (Eberhard 2013, Korenko et al 2015. Data about the behavioral manipulation of pompilid hosts remains limited.…”

“…Although spiders are noted predators of aerial insects, numerous insect lineages have similarly evolved strategies for utilizing spiders as a resource, most notably some ichneumonid wasps, whose larvae are capable of manipulating the behavior and web design of the spider to the advantage of the endoparasitoid [20]. The antiquity of spider-associated insects is virtually unknown, and although the lineages have evolved in parallel since at least the Paleozoic, no evidence has been forthcoming of specific insect lineages prior to the Cenozoic specializing on spiders as prey or clearly utilizing their webs as a retreat.…”
