Diapausing females with physiologically inhibited endocrine system or females with the artificially removed hormonal sources show inactive ovaries and empty AG without secretory products. Ovary-ectomised females have hypertrophic AG loaded with the oily secretion, which shows that there is no direct dependence of AG on ovarian growth. Chemical analysis of the secretory products revealed the presence of acetylated glycerols, with the most abundant stearoyl-diacetyl-glycerol, stearoyl-acetyl-propionyl-glycerol and the corresponding derivatives of arachidonic acid. In addition to this, secretory cells of AG activated by JH produced γ- and δ-tocopherols.
