Fig. 1 in Ultrastructure and development of the new stylets inside pre-molting first instar nymphs of the Asian citrus psyllid Diaphorina citri (Hemiptera: Liviidae)

Fig. 1. Transmission electron micrographs of thin sections in the cuticle and new and old stylets of a pre-molting 1st instar nymph of D. citri. A. Old (oc) and new (nc) layers of the cuticle, with minor (arrow) and major (double arrows) folds in the new cuticle; note the exuvial space (es) between the new and old cuticle, and the epidermal cells (ec) with large nuclei (nu) and nucleoli (ne). B. The old (functional) stylets; note the larger food canal (fc) and a narrower salivary canal (sc) between the 2 interlocked maxillary stylets (mx1, mx2), and a mandibular stylet (md) with 2 dendrites in its central canal (cc); the other mandibular stylet has sprung out (during processing) and is not included in this section. C & D. Two masses of hypodermal cells (hc1, hc2) with large nuclei, and hypodermal cell extensions (hce) that end with developing mandibular (md) and maxillary (mx) stylets on each side. Note that around hc1, 2 sections of each of the (coiled) mandibular and maxillary stylets are shown, but around hc2 only one section of the mandibular stylet can be seen (the rest of the stylet sections are outside the frame of this image). E. Higher magnification of 2 sections in a developing (coiled) mandibular stylet (md1, md2) and a developing (coiled) maxillary stylet (mx1, mx2); fc, part of the food canal; hce, hypodermal cell extension with a large nucleus (nu); sc, part of the salivary canal; inset shows details of the cuticular molding structure (cm).

Fig 1. A parasitoid wasp and 1 of 7 species of predaceous long-legged flies collected in this study. The photograph is insufficient for identification. Although predation events could not be duplicated in captivity, the parasitoid wasp ap- pears to be within a size range that the long-legged fly would attack (e.g., Barrentine 2011). Scale bar = 2 mm.
