潜叶虫潜道图像分析
DOI: 10.3724/SP.J.1145.2012.00134, PP. 134-138
Keywords: 潜叶昆虫,潜道,图像分析,运动路径分析
Abstract:
为通过潜叶虫潜食叶片所留下的潜道分析其分类、行为和生态，应用getdata图形数字化软件和r语言，提取线形潜道的数字化图像，并获得各种图像形状参数，如平均转角、转角集中度、分维d、直线度st、蜿蜒度sn等.结果发现：大多数潜道的平均转角较小（不超过±25.0°），转角集中度较高（>0.600），说明潜食方向大多保持为前进方向；多数潜道的st在0.010到0.300之间，数值极小，而sn一般都超过0.600，表明多数潜叶昆虫潜道的蜿蜒程度非常大；米楮上两种潜叶蛾的潜道形状参数如d和st存在显著差异.图2表2参14
