Insect morphology least three different positions: prognathous, opisthognathous, and hypognathous. In species with prognathous articulation, the head is positioned vertically aligned with the body, such as species of Formicidae; while in a hypognathous type, the head is aligned horizontally adjacent to the body. An opisthognathous head is positioned diagonally, such as species of Blattodea and some Coleoptera. The mouthparts vary greatly between insects of different orders, but the two main functional groups are mandibulate and haustellate. Haustellate mouthparts are used for sucking liquids and can be further classified by the presence of stylets, which include piercing-sucking, sponging, and siphoning. The stylets are

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
