Abstract: | The distribution, external morphology, and ultrastructure of various types of sensilla in the antennae of tenebrionid larvae Tenebrio molitor and Zophobas rugipes are studied by means of scanning and transmission electron microscopy. On the antennae of T. molitor there are sensilla of four basic morphological types: basiconic, styloconic, trichoid, and papillate sensilla. On the antennae of Z. rugipes, in addition to the aforementioned ones, there are placoid sensilla. Ultrastructure points to olfactory function of basiconic and placoid sensilla. Other sensillum types are contact chemoreceptors. |
