Any of various small whitish homopterous insects of the family Aleyrodidae, having long wings and a white waxy body, often injurious to plants.

粉虱一种粉虱的白色同翅昆虫,有长翅及白色似蜡般的躯体,常常对植物造成损害

On the other hand,there has been so far no mapping method and software that can be used to map dominant-recessive markers obtained from F2 population of lepidopteran species.To resolve this problem,two-point and three-point maximum likelihood methods for mapping dominant-recessive markers using F2 population of this type of species were developed in this paper.At,the same time:we also gave a general method for constructing the gene linkage map of this type of species using F2 population.

另外,目前还没有任何方法和软件可以用杂交F2群体来作图鳞翅目类昆虫,如家蚕等连锁图谱,为了解决这一问题,本文发展了用F2群体作图这类昆虫连锁图谱的两点和三点极大似然法,同时还给出了大群体作图形态基因连锁图谱的一般方法。

This paper extracted and analysed 11Math-Mophological Features such as Area, Perimeter, X-Length, Y-Length, Shape-Parameter, Lobation, Sphericity, Circularity, Roundness, Eccentricity and HoleNumber. Based on 40 species of insects which belonging to 8 Orders, 25 Families. And then ranks the accountability of 11 features each in insect identification while assessing their implication to insect taxonomy on levels of Order, Superfamily, Family and Species. More than those, also describes the kinship among the insects of various categories within the same level from the perspective of mathematical morphology through cluster analyses.

论文对隶属于8个目25科的40种昆虫利用计算机视觉技术进行了自动鉴别研究,从昆虫图像中提取和分析了这些昆虫的面积、周长、横轴长、纵轴长、形状参数、叶状性、球状性、圆形性、似圆度、偏心率、亮斑数等11项数学形态特征,并分别探讨了在目、总科、科及种分类阶元上这些数学特征在昆虫分类中的应用可能性和可靠性,利用聚类分析从数学形态学角度对所涉及到的同阶元昆虫类群的亲缘关系做了描述。

Shape and color characteristics were used to form the separated pattern vector and RBF network was used as classifier for each pattern. Each classifier was linearly combined to give the final identification result. Shape pattern consists of rectangularity, elongation, roundness, sphericity, lobation and seven movement invariants. R, G, B, L histogram and R.G chromaticity histogram were treated as separated color characteristic vector.

昆虫图像的形态特征值由矩形度、延长度、球状型、叶状型、似圆度和 7个Hu不变矩等12个特征值组成,颜色特征值由红、绿、蓝、灰度真方图及基于红、绿的二维色度直方图特征值分别组成,然后建立径向基神经网络分类器,每一特征向量由独立的径向基神经网络做为分类器,最终识别由每个分类器识别结果的线性组合而成。
