The ultrastructure of an olfactory sensillum on the maxillary palps of Locusta migratoria (L.)

  • 74 Accesses

  • 20 Citations


The olfactory sensilla on the maxillary palp tip of Locusta migratoria (L.) resemble the surrounding contact chemoreceptors in general morphology. The perforated peg has a thicker wall than is commonly found in olfactory sensilla. The form and position of the sensilla are considered in relation of the olfactory function. The fine structure of the dendrites is discussed in relation to that described in other olfactory sensilla.
