Reproduction

the best-known species in this regard is the desert locust S. gregaria, which begins to show elements of sexual behavior between 6 and 12 days after eclosion. Paralleling the onset of this behavior is a change in body color, from the grayish-brown-pink of newly emerged insects to the uniform yellow of mature males, and the beginning of secretion from epidermal glands of a maturation-accelerating pheromone. The work of Loher, Odhiambo, and Pener (references in Pener, 1974, 1983) established that the changes are controlled by JH in this species. For example, allatectomy shortly after eclosion leads to retention of immature coloration and a lack of desire to copulate, effects that may be reversed by implantation of corpora allata from mature individuals. Similar procedures have demonstrated JH-controlled sexual behavior in the males of some other species. However, in male migratory locusts, L. migratoria ssp. migratorioides, the corpora allata control only the development of the mature body color; mating behavior is controlled primarily by specific median neurosecretory cells in the brain. The control exerted by the cells is direct, that is, not mediated through the corpora allata.
