Abstract

LOCUSTs such as Schistocerca gregaria (Forskal), LOCUSTa migratoria migratorioides, Reiche and Fairmaire, Dosciostaurus maroccanus Thunberg are separated from other species of Acrididae (grasshoppers) because they produce gregarious PHASE. In this article it is speculated that ecological stress is the main factor for changing GRASSHOPPERs into LOCUST. LOCUST outbreak and PHASE change are characterized by changing their hormonal system. LOCUST outbreak in relation to the PHASE polymorphism has been the subject of many studies and reviews. Density dependent factors in LOCUSTs change their morphometrics, physiology (colouration, enzymes), reproduction, cytogenetics and development as a result of PHASE transformation. There are some similarities between changes of LOCUST to gregarious PHASE and insect outbreak after feeding on stressed plants. All stressors such as poor soil and dry season affecting plants can have some effects on LOCUST PHASE transformation. Stress is a response to nonspecific environmental demand, and pathogen or parasites also produce stress response in LOCUST. Environmental cues can produce reaction in stressed LOCUST by gene expression and produce or change the endocrine and enzyme secretions. Therefore, polymorphic variation observed in LOCUST populations during PHASE transformation is their response to local climate or host plant conditions. Factors affecting the fitness of LOCUST can select special life history traits and may have been the reason for selection of LOCUST life cycles as compared to GRASSHOPPERs
