Dissection of Helicoverpa armigera and Helicoverpa assulta sex pheromone glands.

The pheromone glands in H. armigera (a) and H. assulta (b) were squeezed out from the abdomen using forceps (the gland is similarly inflated when the female calls). The abdomen of H. armigera (c) and H. assulta (e) were cut at the sclerotized cuticle from the 8th abdominal segment and the sclerotized cuticle was removed (H. armigera (d) and H. assulta (f)) before immersing the glands in liquid nitrogen. 1: Sclerotized ovipositor valves; 2: Pheromone gland; 3: Sclerotized cuticle that was removed.
