Abstract

We report here the case of a metazoan parasite, a strepsipteran, that manipulates host epidermal tissue and wraps itself within it; which probably camouflages the endoparasite and is recognized as ``self'' by the host. This mechanism is one of immune avoidance among parasitoid insects. The host-derived epidermal ``bag'' might have enabled Strepsiptera to radiate to disparate hosts compared with the relatively few taxa (596 species) described so far. They have been recorded as parasitizing 34 families belonging to seven orders of Insecta. We also report a mechanism of insect ecdysis between the first- and second-instar larva, while enclosed in the bag.

  • Key differences between the loss of complete metamorphosis via type I and II paedomorphosis are that reproduction remains primarily sexual in type II groups and there is a single life cycle strategy in type II groups.

    “Key differences between the loss of complete metamorphosis via type I and II paedomorphosis are that reproduction remains primarily sexual in type II groups (although see Silvestri, 1943; Kathirithamby et al. , 2003 for possible exceptions to this rule in Strepsiptera) and there is a single life cycle strategy in type II groups.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
