Abstract

The wings of insects such as the striped slant faced grasshopper, Amphitornus sp., are highly compartmentalized by their major and minor veins. The compartments are believed to be potential candidates for separate developmental modules which may correspond to distinct cell lineages and domains of gene expression. Are the entire wings of striped slant faced grasshopper, Amphitornus sp is single integrated? Or, are the compartments, even smaller part of the wings can be considered as autonomous units of "gene regulation?” Hence, this study was conducted to determine the number and pattern of developmental modules in the wings of striped slant faced grasshopper, Amphitornus sp. Different hypotheses were formulated and tested to determine the developmental modules in the wings, as well as the veins that bound each compartment. TPSUtil and TPSdig2 and, Modularity and integration tool (MINT ver 1.5 ) were the softwares used in this study. A total of 7 and 14 a priori models for the fore- and hindwing respectively were constructed, and statistically analyzed. Results showed that fore-and hindwings are comprised of 4 and 3 modules respectively bounded by their main veins and there is fair consistency in the number of pattern of developmental modules. Therefore, compartments in wings correspond to “units of gene regulation.”
