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)

Ovipositor of A. procerae. (a) Extremity of the abdomen of A. procerae showing the valvulae at the distal end of the stylet. ts1: trichoid sensillum of type 1. (b) External surface of the distal end of a 3rd valvula bearing several types of trichoid sensillae; ts2: trichoid sensillum of type 2; ts3: trichoid sensillum of type 3. (c) Extremity of a 3rd valvula showing 3 sensillae of type 3. a: sensillum of type a. (d) Internal surface of the distal end of a 3rd valvula, viewed in profile. The interior of the valvula is empty. A trichoid sensillum of type 4 is seen. ts4: trichoid sensillum of type 4. (e) Distal extremity of the stylet of the ovipositor viewed in profile. The 2nd valvulae are carried by the 1st valvulae. v2: 2nd valvula; cs: campaniform sensillum. (f) Distal end of the dorsal surface of a 2nd valvula showing 10 denticulations making a united lancet. d: denticulation. (g) Styloconic sensillum of type 3 on the external surface of the proximal part of a valve 2. ss3: styloconic sensillum of type 3. (h) Distal extremity of the ventral part of the stylet of the ovipositor viewed in front. v1: valve 1; a: campaniform sensillum of type a. (i) Sensillum of type b located on the half proximal part of the external surface of a valve 1. b: sensillum of type b. (j) Sensillum of type c located on the half proximal part of the external surface of a valve 1. c: sensillum of type c. (k) Sensillum of type d, observed on the external surface of the proximal part of a valve 1. d: sensillum of type d. (l) Sensillum of type e, located at 120 𝜇m of the distal extremity of a valve 1. e: sensillum of type e. (m) External surface of the distal extremity of a valve 1. The three sensillae of type f are distributed in triangle. f: sensillum of type f. (n) Sensillum of type g located at the half proximal part on the external surface of a valve 1. g: sensillum of type g. (o) Campaniform sensillum located at the 2/3 proximal of the a valve 1. cs: campaniform sensillum. (p) Three rows of styloconic sensillae of type 1 and 2 on the external surface of the distal extremity of a valve 3. ss1: styloconic sensillum of type 1; ss2: styloconic sensillum of type 2.
