Duration of the Larval, Pupal, and Moth Stages of the Southern Pine Coneworm Dioryctria Amatella (Hulst)

Informally Refereed

Abstract

The day's duration of each developmental stage of the southern pine coneworm, Dioryctria Amatella (Hulst),when reared on artificial medium was determined under controlled laboratory conditions. These results will provide a method for estimating the availability of the different stages during rearings without the necessity of measuring larval-head capsule widths or closely observing colonies for evidence of larval ecdysis, pupation, or moth emergence.

Keywords
