Poor or excessive nutrient management may result in generation of mosquitos in vineyard which is a potential impact of vineyard on residential area. Some species of mosquitos are real threat for human society. For instance, a linkage was observed between vineyards and West Nile virus which spreads via mosquitos [1]. Thus, continuous effective monitoring system is required to ensure mitigation of mosquito borne diseases originated from orchards and vineyards. Numerous image-based machine learning (ML) approaches has been utilized in mosquito systematics, but considering the small body size, these models often required high resolution images and sophisticated pre-processing algorithm to result in high accuracy. Moreover, those classifiers often do not generalize well across different datasets due to a relatively small number of Aedes samples. In this paper, we adopt a one-class perspective for mosquito detection, where the detection classifier is trained with Aedes vigilax mosquito class samples only, which is a major coastal pest species for NSW and more northern areas, and also for parts of coastal SA. Our model employs a BERT-BiLSTM module for feature extraction and a one-class SVM for classification. A comprehensive evaluation with a benchmarking dataset demonstrates the better performance of our model than existing approaches.
