List of chemical compounds on cockroaches and cocoons.

Chemical composition of solvent extracts of parasitized P. americana cockroaches and A. compressa cocoons as well as mean amounts [µg] ± standard deviation of substances found in single extracts (n = 28). Compounds derived from A. compressa larvae (‘larval substances’) are in boldface type.LRI = linear retention index (calculated in relation to n-alkanes) on a RH-5ms+ column.*Identified by comparing mass spectrum and retention time with a synthetic reference compound.All other compounds were identified by comparison with data from earlier analyses [1], [53].
