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,
International Centre of Insect Physiology and Ecology International Centre of Insect Physiology and Ecology The International Centre of Insect Physiology and Ecology (ICIPE, branded as icipe) is an international scientific research institute, headquartered in Nairobi, Kenya that works towards improving lives and livelihoods of people in Africa. icipe was founded in 1970 by a renowned Kenyan entomologist, Thomas Odhiambo, with strong encouragement from Carl Djerassi, a professor of Chemistry at Stanford University. icipe is a member of "Association of International Research and Development Centers for Agriculture" (AIRCA). The center’s main objective is to research and develop alternative and environmentally friendly pest and vector management strategies that are
