Summary
-
1.
The removal of one or both antennae reduces the speed with which larval and adult (♀+♂) Locusta migratoria climb or run towards light.
-
2.
The effect is greater with both antennae removed than with one.
-
3.
Therefore in addition to their perceptive function, the antennae also have a stimulating (dynamogenous) function, as in the case of Anacridium aegyptium.
