NOTES ON THE BIOLOGY OF CERTAIN TORTRICID SPECIES WITH STRUCTURAL DETAILS OF THE LARVAE AND PUPAE

Abstract

Biological notes are given on six species of Tortricidae—Sparganothis directana Wlk.; Tortrix alleniana Fern.; Cacoecia myricana McD.; Cacoecia parallela Rob.; Tortricodes horariana Wlshm. and Peronea cornana McD.: three species of Eucosminae—Epinotia lindana Fern.; Epinotia myricana McD. and Anchylopera semiovana Zell.: five species of Argyroplocinae—Exartema cornanum Heinr.; Exartema permundanum Clem.; Exartema valdanum McD.; Argyroploce albiciliana Fern, and Evora hemidesma Zell.A comparative study of the setal pattern of both head and abdomen in the larvae of the above-mentioned species is presented and the main structural details of the pupae are also described. In this connection a critical comment on both Fracker's and Mosher's generic keys, based respectively on larval and pupal characters, is offered.
