Název v původním jazyce
A role for ecdysteroids in the phase polymorphism of the desert locust.
Popis výsledku v původním jazyce
Locusts show density-dependent continuous phase polymorphism; they appear in two forms or phases, gregarious and solitary, and there is a continuous range of intermediates between the extreme phases. Although earlier studies showed that there are no major phase-dependent differences in the titres of ecdysteroid in the haemolymph of desert locusts, Schistocerca gregaria , recent studies showed some minor differences in the timing of the main peak of ecdysteroids. In crowded penultimate- and last-instar hoppers, peak titres were lower but longer-lasting, whereas in isolated hoppers they were higher but of shorter duration. The major component of the haemolymph peak of ecdysteroid was 20-hydroxyecdysone in both isolated and crowded hoppers, but differences were found in the relative amounts of two minor components (makisterone A-like compound and highly polar products). In S. gregaria adults, the regression of the prothoracic glands was irregular and subject to high individual variations,
