Application of Insect Mathematical Morphology in Gender Recognition of Peach Longicorn Beetle (Coleoptera : Cerambycidae) Adults
In order to clear the difference between female and male of peach longicorn beetle [Aromia bungii(Faldermann)] adults,morphological parameters of the beetle adults were obtained and analyzed by image processing techniques and insect mathematical morphology methods.The results indicated that the right-left-coxal cavity gaps and antenna length were significantly different between female and male adults,but not in terms of body length,pronotum length and width.Consequently,the individual size (body length) by oneself should not be the parameter in distinguishing female and male adults of the beetle.Significant differences emerged in the width of right and left elytra in three sets of data(female,male,female and male) by comparing paired characteristics,but the significance of other parameters was not same in different sets of data.In terms of parameter ratio,significant differences were found in such as elytra length/width,each segments/antenna length,pro-femur/propodium length,each parts/mesopodium length between two gender samples.In addition,many pairs of characteristics from female and male beetles hadfluctuating asymmetry in measured parameters.As a consequence,the difference between female and male adults of A.bungii can be distinguished by mathematical morphology,and the asymmetry of many parameters is found in this study.
