Comparative Study of the Morphology of the Ovipositor of Platygaster diplosisae (Hymenoptera: Platygasteridae) and Aprostocetus procerae (Hymenoptera: Eulophidae) Two Parasitoids Associated with the African Rice Gall Midge, Orseolia oryzivora (Diptera: Cecidomyiidae)

Figure 1

Ovipositor of P. diplosisae. (a) View of the abdomen showing the ovipositor at its distal end. abd: abdomen. (b) Front view of the ovipositor of P. diplosisae. Several sensillae are seen on the 3rd valvulae. a: trichoid sensillum of type a; b: trichoid sensillum of type b; c: sensillum of type c; d: sensillum of type d. (c) Valves 3 showing 2 types of trichoid sensillae. a: sensillum of type a; b: sensillum of type b. (d) Distal end of the 3rd valvulae with 2 types of trichoid sensillae. c: sensillae of type c; d: sensillae of type d. (e) Two campaniform sensillae located at the proximal portion of the 3rd valvulae. v3: 3rd valvula; sc: campaniform sensillum. (f) Sensillum of type d observed on the distal end of the 3rd valvula. d: sensillum of type d. (g) Distal end of the ventral part of a 2nd valvula viewed in profile. Five denticles are seen on this valvula. v2: 2nd valvula. (h) 1st valvula of the ovipositor. They appear large in their proximal portion and more and more slender near their distal end. v1: 1st valvula. (i) Two campaniform sensillae on the proximal portion of a 1st valvula. v1: 1st valvula.
