Abstract:

The antennal sensilla of female parasitoid, Ceratosolen sp. (Hymenopte

ra: Agaonidae), were observed with scanning electron microscopy (SEM). The anten

na was geniculate in shape, and consisted of three basal segments. Thirteen type

s of sensilla were distinguished, including sensilla trichodea (1 type), multipo

rous placoid sensilla (1 type), basiconic sensilla (2 types), basiconic capitate

 peg sensilla, chaetica sensilla (4 types), coeloconic sensilla (3 types) and on

e specialized sensillum regarded as sensillum obscurum. The morphology, abundanc

e, distribution of the sensilla was recorded. Their putative functions were anal

yzed based on selected staining results and wasp behavior observed in the field.

 Furthermore, the ecological significance of the sensilla was also discussed in

relation to the specific relationship between the fig/wasp mutualism.
