Three Apium graveolens (L.) varieties and cultivars within varieties were evaluated for host plant suitability to two polyphagous lepidopteran herbivores: the beet armyworm, Spodoptera exigua (Hiibner), and the cabbage looper, Trichoplusia ni (Hiibner). Overall, there were no significant differences in survivorship, developmental time, and pupal weight of S. exigua or T. ni reared on the two va...

during a survey of plant-parasitic nematodes in bamyan and mazar sharif provinces of afghanistan, several species of plant-parasitic nematodes belonging to infraorder tylenchomorpha were detected and identified. filenchus facultativus; filenchus discrepans; filenchus elegantulus; boleodorus volutus; neopsilenchus magnidens; coslenchus costatus; ditylenchus myceliophagus; tylenchorhynchus clarus...

Abstract The subject of this paper is the semantically based postprocessing of color–coded images such as classification results. We outline why the classical definition of mathematical morphology suffers if it is used for processing of coded image data. Therefore we provide an extension for morphological operations such as dilation, erosion, opening, and closing. With a new understanding of mo...

Classical morphology is built up in such a way that all operators occur in pairs, e.g., dilation and erosion, opening and closing, etc. This phenomenon, which is a straightforward consequence of the duality principle, often prohibits the construction of tools that treat foreground and background of signals in exactly the same way. In this paper we discuss an alternative framework for morphologi...
