Abstract
The sense receptors on the antennal flagellar segments of males and females of Nasonia vitripennis (Walker) and Peridesmia discus (Walker) are identified and compared using the scanning electron microscope (SEM). Antennae of female and male N. vitripennis differ by the presence in females of tactile trichoideal hairs on flagellar subsegments 11 and 12, by variation in the number of previously unreported basiconic capitate pegs on subsegments 6-10, and by the presence of an unreported campaniform sensillum on subsegments 4 and 8. Except for the absence of campaniform sensilla and differences in the number and arrangement of individual receptors, similar structures were located on P. discus antennae. The need for additional histological and behavioral studies to determine accurately the use of the receptors in courtship and host-selection behavior of parasitic Hymenoptera, and the potential for the use of the SEM in systematic and behavioral research of the Chalcidoidea are indicated.
