[Capacity for regulation of food intake and growth of fifth stage larva of Locusta migratoria M. R and F (Orthoptera, Acrididae) in various conditions of fasting and temperature].
Migratory locusts in the fifth instar, have two feeding periods, one obligatory, the other accessory; the duration of which depends on growth and moult. Quantitative data about food intake, are estimated by weighing frasses each day. Food intake raises and decreases gradually between two moults. Starvation during one day is made up for by feeding more during the accessory period. Rearing larva under constant or alternating temperatures, shows that in the three experimented conditions, obligatory feeding period coincides with a daily food intake increasing regularly to raise a maximum at the end of this first period and decrease afterwards in the accessory period.
