TI  - Sexual dimorphism in antennal morphology and sensilla ultrastructure of 
      Dendrolimus tabulaeformis Tsai et Liu (Lepidoptera: Lasiocampidae).

AB  - Insects rely heavily on olfaction to locate habitat, mates, and oviposition 
      sites, while odorant molecules and the antennal olfactory sensory cells of 
      insects are two indispensable components of olfactory response. Our previous work 
      identified the sex pheromones and volatile compounds derived from host plant of 
      Dendrolimus tabulaeformis Tsai et Liu, a serious economic pest of pines in 
      northern China. However, little is known about the olfactory system of D. 
      tabulaeformis, especially in females. To make a better understanding of the D. 
      tabulaeformis olfactory response, we investigated the structure, innervation, 
      numbers, and distribution of sensilla on the antennae of male and female moth, 
      based on scanning and transmission electron microscopy. The pinniform antennae of 
      this moth bear five types of sensilla: trichoid (TS), basiconica (BS), styloconic 
      (StS), and chaetica (ChS) sensilla, and belt-type structures (BTSs). The BTSs are 
      hollow and are not chemical sensilla. The ChSs occur on the scape. StS contain 
      dendrite sheaths and four dendrites containing microtubules in their cores. The 
      BS contents are continuous with that in the subsegments. The TSs were sexually 
      dimorphic and could be divided into 12 subtypes based on dendrite number and 
      form. TS1-4 contained two, three, or four dendrites and were similar in both 
      sexes. TS 5-8 and TS 9-12 occurred only on male and female antenna, respectively. 
      We discussed the possible functions of these sensilla.
