Terms

  • acrididae - a family of insects that comprise the grasshoppers with short antennae, short ovipositor, and tarsi of legs three-segmented.
  • blastokinesis - active movement of the grasshopper embryo by which it passes from the ventral to the dorsal side of the egg and at the same time revolves 180 degrees on its long axis.
  • brood - all the individuals that hatch at about one time from eggs laid by one series of parents and that normally mature at about the same time; a group of individuals of a species that have hatched into young or have become adult at approximately the same time, and live together in a defined and limited area, and they may be of different generations.
  • chorionic sculpturing - a network pattern on the chorion (shell) of the insect egg.
  • complete metamorphosis - metamorphosis through which the insect develops by four distinct stages: egg, larva, pupa, adult.
  • diapause - a state of low metabolic activity mediated hormonally and associated with ceased growth, reduced activity, and increased resistance to environmental extremes.
  • eclosion - the hatching of the larva or nymph from its egg.
  • egg pod - a case made of grasshopper gluelike secretions and soil particles enclosing a clutch of grasshopper eggs.
  • fledge - acquisition of the adult wings.
  • gradual metamorphosis - metamorphosis through which the insect develops by three distinct stages, namely egg, nymph, adult.
  • instar - the immature insect between two successive molts.
  • larva - (pl., larvae) the immature insect hatched from the egg and up to the pupal stage in orders with complete metamorphosis, e.g., a caterpillar.
  • metamorphosis - the change of body form through which insects pass in developing to the adult.
  • nymph - an immature insect of species with gradual metamorphosis.
  • ovipositor - in grasshoppers the paired digging and egg laying structures at the end of the female abdomen
  • ovipositor valves - three pair of digging and egg laying structures at the end of the abdomen in female grasshoppers.
  • preoviposition period - the period between molting to the adult and the laying of the first group of eggs; in grasshoppers the period normally lasts one to two weeks.
  • pupa - (pl., pupae) the stage between the larva and the adult in insects with complete metamorphosis; a nonfeeding stage in which adult structures develop and grow.
  • seasonal cycle - the timing of the periods of egg hatch, nymphal development, adulthood, and reproduction.
  • stadium (pl., stadia) - the time period between two successive molts of larvae or nymphs.
  • subgenital plate - in the male grasshopper the terminal ventral plate underlying the genitalia.
  • threshold - the temperature or level of hormone concentration that must be reached before development or growth can begin.
