Description
Typical of Bactrocera larvae with the following specific characteristics for the third instar:
Body. Body length 8–10mm.
Head. Stomal organ: number of peg sensilla four or more (4–5, long); peg sensilla unbranched; other peg-sensilla-like structures absent. Stomal region: secondary lobes short, leaf-like (5, large); margins of secondary lobes all entire. Number of oral ridges 11–16; margins dentate (medium to long, sharply pointed teeth). Accessory plates small, numerous; margins serrated. Median oral lobe absent or not protruding.
Spinules and creeping welts. Dorsal spinules on segments T1-T3.
Anterior spiracles. Anterior spiracle convex to flat. Anterior spiracular tubules 11–14.
Caudal segment (a8) and anal lobes. Anal lobes plainly visible, but not protuberant; simple.
Posterior spiracles. Slits 3x longer than wide (about). Length of slits 52-66 µm. Dorsal spiracular processes with numerous trunks arising from an elongate base (medium processes). Number of dorsal spiracular processes 17–24. Number of ventral spiracular processes 17–24. Number of lateral spiracular processes 8–12. Basal width of spiracular processes 2.0-4.4 µm. Average number of tips 25-35. Ratio of number of tips to number of trunks 1.9-2.7.
