AbstractThe posterior apophyses in terminal abdominal segments of female moths form part of the sex pheromone gland in each of three species examined (Choristoneura fumiferana (Clem.) (Tortricidae), Trichoplusia ni (Hübner) (Noctuidae), Orgyia leucosligma (J.E. Smith) (Lymantriidae)). Four groups of paired dorsolateral muscles are attached to the anterior or posterior apophysis and the integument. An additional group is attached to the anterior and posterior apophyses. The probable relationship of these muscles to the eversion, or protrusion, and inversion of sex pheromone glands is discussed.

In female Trichoplusia ni, granular haemocytes are observed near the basement membrane of developing sex pheromone gland cells while plasmatocytes are observed near the basement membrane of unmodified epidermal cells. The basement membrane underlying gland cells is clearly different from that of other epidermal cells. There is a thin amorphous layer (layer 1) which is also present beneath unmodified cells, and a second layer (layer 2) apposing the haemocytes. Layer 2 is distinctly banded which results from tubules similar in dimensions and structural appearance to those observed within granules of the granular haemocytes. The observations indicate that the granules participate in the formation of layer 2 by emptying their contents into the haemocoel next to layer 1.

The major component of the sex pheromone of the eastern spruce budwonn was established by Weatherston et al. (1971) to be trans-11-tetradecenal. Subsequently it was found (Sanders and Weatherston 1976) that a small proportion of cis-11-tetradecenal was essential to attraction and indeed was a component of the natural pheromone. In addition Weatherston and Maclean (1974) have shown that the female sex pheromone gland contains trans-11-tetradecenol, a presumed biosynthetic precursor to the aldehyde.

The sex pheromone glands of two females of the fall webworm Hyphantria cunea Drury (Lepidoptera Arctiidae) that were discovered in Auckland in March 2003 were extracted in hexane and were subjected to GCMS analysis Four compounds were identified (9Z12Z15Z)octadeca91215trienal (9Z12Z)octadeca912dienal (3Z6Z)9S10Rcisepoxyhenicosa36diene and (13Z6Z)9S10Rcis910epoxyhenicosa136triene The ratio of these four compounds in the gland extracts was 660627901 Except for a trace amount of the trienic epoxide detected in the New Zealand sample the ratio of the three other compounds was very similar to native North American females of this species A direct comparison between the synthetic commercial lure Nitolure and the sex pheromone gland of females found in New Zealand indicates that the sex pheromone gland contains significantly more of (3Z6Z)9S10Rcisepoxyhenicosa36diene than the synthetic lure while the lure lacks the trace amount of the trienic epoxide Therefore the effectiveness of Nitolure at trapping fall webworm in New Zealand remains uncertain
