Pupal and adult parameters as potential indicators of cottonwood leaf beetle (Coleoptera : Chrysomelidae) fecundin and longevity

Cottonwood leaf beetle, Chrysomela scripts, pupae from a laboratory colony were weighed and monitored through adult emergence, oviposition, and mortal ity to determine if correlations existed between various pupal or adult par ameters and fecundity or longevity. Forty-three female cottonwood leaf beet les were monitored. Pupal weight was not a good indicator of fecundity, tot al oviposition events, number of eggs/beetle/day, or adult longevity. In ad dition, adult weight showed very low correlation with fecundity, adult, lon gevity, total oviposition events, or number of eggs/beetle/day. adult weigh t was a marginal indicator of the number of eggs/beetle/day, and correlated well with adult body length. Adult longevity could be used to pre-diet fec undity.
