The gender identification of silkworm pupae is a critical step in the sericulture industry's breeding process. In this study, a low cost, short-wavelength (815-1075 nm) near infrared (NIR) spectrometer combined with multivariate spectra evaluation methods was used to establish calibration models for the on-line identification of female and male pupae of eight silkworm varieties (Hibiscus, Jingsong, 932, Xiang Hui, 7532×Xiang Hui, Haoyue B, Jingsong B, and 7532). The diffuse reflection short-wavelength spectra were recorded, and then principal component analysis (PCA), linear discriminant analysis (LDA), and partial least squares discriminant analysis (PLSDA) were tested for calibration model development. The PCA and LDA results showed, that spectral differences between the female and male silkworm pupae existed, however, the two evaluation techniques could not separate the female and male silkworm pupae with the required accuracy. The PLSDA calibration models, on the other hand, could separate the pupae according to their gender with the necessary prediction accuracy of >98.44%. Thus, it has been proved, that a low-cost, short-wavelength range NIR spectrometer in combination with a PLSDA calibration routine can be successfully applied for the reliable on-line identification of female and male silkworm pupae.

短波近红外光谱和模式识别技术在线鉴定蚕p性别

蚕p的性别鉴定是蚕桑业育种过程中的关键步骤。在这项研究中,使用低成本,短波长(815-1075 nm)近红外(NIR)光谱仪结合多元光谱评估方法,建立了用于在线鉴定8种蚕varieties雌雄male的校准模型。 (芙蓉,京松,932,项辉,7532×向辉,皓月B,京松B和7532)。记录漫反射短波长光谱,然后测试主成分分析(PCA),线性判别分析(LDA)和偏最小二乘判别分析(PLSDA)以建立校正模型。PCA和LDA结果表明,雌性和雄性蚕spectral之间存在光谱差异,但是,两种评估技术无法以所需的精度分离雌性和雄性蚕p。另一方面,PLSDA校准模型可以根据their的性别分开the,其必要的预测准确度应> 98.44%。因此,已经证明,低成本,短波长范围的近红外光谱仪与PLSDA校准程序相结合,可以成功地用于雌,雄蚕p的可靠在线鉴定。
