Parasitoid genus-specific manipulation of orb-web host spiders (Araneae, Araneidae)
Original language description
1. Araneid spiders of genus Araniella are attacked by three polysphinctine parsitoid wasps Polysphincta boopsTschek, P. tuberose (Gravenhorst), and Sinarachna pallipes (Holmgren). In the present study, the trophic niche of sympatrically occurring parasitoids and the host manipulation they induced were studied. The aim was to identify whether the variation in host response to manipulation is as a result of differences among parasitoids or among host species. 2. It was found that final instar larva forcedthe spider host to build a threedimensional (3D) cocoon web to protect the parasitoid during pupation. The behaviour of parasitoid larva and the induced modification of the web architecture differed between wasps of genus Polysphincta and Sinarachna butnot among three spider species. The larvae of genus Polysphincta forced the spider host to build the cocoon web with a high thread density within which the pupa was positioned horizontally. The larvae of Sinarachna forced the spider hos
