ABSTRACT

Trophallaxis is widely disseminated among social Hymenoptera and the crop is considered to be the region of the digestive tract responsible for food pumping from one insect to another. In the present study, however, the crop has been found to be a simple reservoir since its musculture does not correspond the function attributed to the structure. The behaviour of the digestive tract on the basis of ultramorphology has been dealt with in detail.
