    Additional Comments. The manuscript presented by Shippy et al. revealed that chitinase family genes in Diaphorina citri. Chitin is widely distributed in nature and serves a variety of functions. In insects, chitin is a major structural component of the cuticle and peritrophic membrane, and plays an important role in molting; thus, chitin metabolism related genes can serve as a desired target for pest control. As described in background, chitinase plays an important role involved in digesting the polysaccharide polymer chitin. In the current study, the authors identified and annotated 12 chitinase family genes from D. citri and performed phylogenetic analysis. Additionally, the structural domains and expression patterns of D. citri chitinase genes were analyzed. In general, the manuscript can provide some useful information for D. citri control. This manuscript can be accepted after solving the following questions. 1. According to Table 1, 12 chitinases were identified, including CHT3, CHT5-7, CHT10-1, CHT10-2, CHT11, IDGF1-3, ENGase and CHTPE. However, CHT1-2, CHT4 and CHT8-9 seem to be missing. Please give a proper explain. 2. I suggested that the author should verify the expression levels of these chitinase genes by qPCR or Western blot.

    Are all data available and do they match the descriptions in the paper?

    As with the other manuscripts, OGS v3 is mentioned, but this is not get available from the CGEN. The data underlying table 4 and Fig 3 are available.

    Additional Comments: This manuscript is a comprehensive description of the manual curation of the chitinase family genes, with clear aims and methodology.
