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.

Tubular Endoplasmic Reticulum

The sex-pheromone-producing gland in female Trichoplusia ni (Hübner) is a modified intersegmental membrane and the gland cells are ductless. Lipid spheres are located throughout gland cells and vary both in number and size relative to the age of the female. Most of the lipid is surrounded by oval to elongate distensions of smooth tubular endoplasmic reticulum which contain the enzyme catalase and are thus microperoxisomes. Lipid spheres evert the apical plasma membrane between microvilli, move away from the gland cells, and are stored in the cuticle as discrete lipid deposits. These deposits, in turn, move to the surface of the gland by tubular structures that differ from epicuticular filaments.

In newly emerged and 48-h-old female adults of Lobesia botrana the sex pheromone gland cells are columnar. Organelles characteristic of lipid-producing cells are very prominent. Smooth tubular endoplasmic reticulum is extensively developed but few lipid droplets are observed. Numerous microbodies are present and are located, along with the Golgi complexes, primarily in the vicinity of the nucleus. The apical plasma membrane is folded. The cuticle overlying the gland cells differs from unmodified cuticle in the number and location of epicuticular filaments. They originate near the bases of the furrows between the apical folds.

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.

The New Zealand native moth Tmetolophota atristriga (Walker) (Lepidoptera Noctuidae) is a background pest defoliating pasture This project identified the pheromone components of the female pink grass worm that could be used to trap male moths in a control or monitoring programme Extraction of the sex pheromone gland of virgin female moths and GCMS analysis has identified several compounds in the sex pheromone gland two monounsaturated compounds cis11hexadecenal (Z1116Ald) and cis11hexadecyl acetate (Z1116Ac) and three saturated compounds hexadecan1ol (16OH) hexadecyl acetate (16Ac) and octadecan1ol (18OH) and triene hydrocarbon (ZZZ)369tricosatriene (Z3Z6Z923Hy) A field trapping experiment was conducted using binary blends of the two main compounds Z1116Ald and Z1116Ac at five different ratios (ie 1000 7525 5050 2575 and 0100) The highest catch was obtained at ratio 2575 of Z1116AldZ1116Ac; males were also caught at the 5050 ratio No catches were recorded with any other ratio tested A dose response experiment was conducted testing five loadings of the optimum binary (2575 ratio) mixture (01 1 10 100 and 1000 mg loading) and males were caught only at 01 and 1 mg loadings In a field trapping experiment conducted late in the season (2008) using the three additional minor compounds only the addition of Z3Z6Z923Hy to the binary mixture significantly enhanced male attraction
