Subdivisions of insect wings have attracted special attention due to its possible correspondence to distinct cell lineages and domains of gene expression. Hence, concept of modules comes into mind, which can also be viewed as morphogenetic field and units of gene regulation. This study was conducted to delimit the spatial domain of developmental modules in the fore wings of the selected population of Rice grasshopper, Oxyasp by determining the possible number and pattern of developmental modules defining the shape of the hind wings. Different hypotheses were formulated and tested using MINT software (Modularity and Integration Tool, ver 1.5) as to possible developmental boundaries based on wing venation. A total of 180 points were used to trace and outline the margins as well as the major of the hind wings. Results of this study show that wing compartments bounded by major veins are potential candidates for separate developmental modules that may correspond to distinct cell lineages and domains of gene expression. The entire hind wing was observed to have 3 best-fit models indicating that the compartments could be considered as autonomous units of morphological variation that may correspond to domains of gene expression. Major veins serve not only as boundaries but also as active center of integration.
