Effects of the rearing temperature upon growth and hormonal balance inSchistocerca gregaria during the last two larval instars

Summary

A fall in diurnal rearing temperature (from 33°C to 28°C) during the 2 last larval instars ofSchistocerca gregaria induces a lengthening of development and a slowing down of growth. At 28°C, circulating levels of juvenile hormones, particularly those of JH3, diminish from the middle of the 4th instar but ecdysteroids and proteins accumulate in haemolymph.
