A diet of senescent Brassica spp. delayed sexual maturation in the desert locust. The senescent leaves were shown to be short of gibberellins, and a dietary supplement of gibberellin A(3) (1 microgram per locust per day) restored the rate of maturation to that found in animals feeding on green leaves. An external application of eugenol had a similar effect. The sexual immaturity of desert locusts during the dry season may result from the senescent condition of their desert food plants.
食用衰老的十字花科植物会延迟沙漠蝗虫的性成熟。研究表明，衰老叶片缺乏赤霉素，而添加赤霉素A（3）（每天每只蝗虫1微克）可使成熟速度恢复到以绿叶为食的动物的水平。外用丁香酚也有类似效果。沙漠蝗虫在旱季的性不成熟可能是由于其沙漠食物植物的衰老状态所致。
