Pebrine diagnosis using quantitative phase imaging and machine learning

Journal of Biophotonics, 2021
AbstractPebrine is the most dreaded infectious disease of the silkworm and has devastated sericulture in Europe during the 18th century. Thereafter, if it is detected, the crop is burned to prevent further dissemination. The conventional microscopic examination of moth's body fluid is erroneous and it exacerbates on Metarhizium anisopliae (MA ...

Research on Image Segmentation Technique for Pebrine in Silkworm Based on HSI Model

Advanced Materials Research, 2010
To segment the pebrine from the background effectively, this paper focuses on the research of image segmentation technology on the basis of HSI color model. Owing to the complex background and poor contrast of the pebrine image, the method of contrast enhancement is adopted to improve the image quality; the technology of target extraction based on HSI ...

Standardization of mother moth examination for pebrine detection in samia species and diagnosis of pebrine disease in commercial seed production

The Clarion- International Multidisciplinary Journal, 2017
The Eri silkworm of the genus Samia is infected by protozoan disease pebrine caused by microsporidian Nosema species. The disease is transmitted to the next generation either through the eggs or consumption of contaminated leaves and it hinder eri seed production.

Application of Pebrine Detection by PCR Infected <i>Bombyx Mori</i> Eggs

Advanced Materials Research, 2011
With the development of the PCR technology, especially the improvement of its reagent and a method of pebrine detection by PCR in infected Bombyx mori eggs was established.With the 16sRNA gene of Nosema bombycis as target sequence, the results of extraction of genomic DNA from purified microspores showed that 1.3×10-7µg DNA can be extracted from each ...

Vision sensing system for early detection of Pebrine spore in silk moth

2012 Sixth International Conference on Sensing Technology (ICST), 2012
An important aspect of silkworm seed production is to ensure Pebrine disease free eggs. For that reason, the egg-laying moths are cut and their tissues are examined under microscope for presence of Pebrine spores in those tissues. If the tissues are found free of infection, then only the corresponding eggs are distributed amongst the villagers pursuing

Research on Automatic Detection Technique for Pebrine Image Based on Computer Vision

Advanced Materials Research, 2010
Aiming to achieve the automatic detection and accurate identification of pebrine images, the fuzzy contrast enhancement algorithm was utilized to enhance the contrast of the target image in order to improve the image’s quality; Owing to the color character of light green for the pebrine, the image segmentation technique based on the HSI model can be ...
