Petiole (insect anatomy) a pedicel, but in entomology, that term is more correctly reserved for the second segment of the antenna; while in arachnology, 'pedicel' is the accepted term to define the constriction between the cephalothorax and abdomen of spiders. The plump portion of the abdomen posterior to the petiole (and postpetiole in the Myrmicinae) is called the gaster. The structure of the petiole is an easy way to visually classify ants, because the major subfamilies of Formicidae have structural differences: some ants have two-segmented petioles, while others have a single-segmented petiole. Petiole may also be used in the context of wing veins,
Insect farming land use. This results in a tremendous amount of land-cover change which destroys local ecosystems and displaces people and wildlife. Insect farming is minimally space intensive compared to other conventional livestock, and can even take place in populated urban centers. Insect farming Insect farming is the practice of raising, eating, and breeding insects as livestock. Insects may be farmed for the commodities they produce, or for them themselves; to be used as food, as a dye, and otherwise. Silkworms, the caterpillars of the domestic silkmoth, are kept to produce silk, an elastic fiber made when they are in the process
