Autor: Hassane Mahamat, Ahmed Hassanali, Sayed El Bashir, Nabil Bashir, Yousif O. H. Assad, Baldwyn Torto

Publikováno v: Journal of Chemical Ecology. 23:1373-1388

The effect of the presence of gregarious fifth-instar nymphs on the sexual maturation of newly molted gregarious immature adult males and females of the desert locust S. gregaria was investigated by monitoring color changes (yellowing of body), sexua
