The ovipositor is composed of two papillae densely packed with medium length mechanoreceptor sensilla (MRb: 80-160 μm, n=420−460). Long mechanoreceptor sensilla (MRa: 250-300 μm, n=20−24) and contact chemoreceptors (CRa: 30-40 μm, n=20−28) are evenly distributed at the periphery of these papillae. Legs support contact chemoreceptors (CRa), scattered among the scales. The pretarsus structure of each leg includes a single contact chemoreceptor (125 μm) inserted dorsally. The fifth tarsomere bears a ventral area without scales on which contact chemoreceptors are disposed in two parallel rows (CRb: 40-60 μm). A sexual dimorphism was found in the number and density of these sensilla (females: mean = 5.3, SD=1.0; males: mean = 3.3, SD=0.7), and in the size of the sensory field. The possible involvement of these sensory structures in oviposition site selection is discussed.
