The septicemia of insect hemolymph caused by gram negative bacteria is an important infestation mechanism of nematode-bacteria symbiont. The product of metabolism released by <em>X. nematophila<\/em> is highly noxious to insect hosts. We want to explore the infestation biomarker of nematode-bacteria symbiont by taking <em>Bactrocera dorsalis <\/em>as a research model.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Can you explain that to a non-scientist?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The entomopathogenic nematodes (EPNs) have been used in classical, conservational and augmentative biological control programs. <em>Steinernema carpocapsae<\/em> is a famous EPN which has been widely used in IPM. In fact,&nbsp; <em>S. carpocapsae<\/em> could not finish the host infestation independently. The infestation of nematode-bacteria symbiont (e.g. <em>Steinernema carpocapsae<\/em> and <em>Xenorhabdus nematophila<\/em>) could kill insect host (e.g. <em>Bactrocera dorsalis<\/em>) very effectively, normally within 24 hours. Therefore, we assumed there should be an effective bioactive substance released by nematode-bacteria symbiont. The key biomarker released by nematode-bacteria symbiont is the key compound of insect death. The determination of infestation biomarkers would have potential application for development of novel biopesticides.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\"><p>The determination of infestation biomarkers would have potential application for development of novel biopesticides.<\/p><\/blockquote>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"alignleft is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/lh5.googleusercontent.com\/KLyOtP0IVGfu31t1qQ-zJUH39CNxiAxhHCfRmWuROpwOkE7NqhiWgeutXFt-HXlzAy2L5VHIKg5r3xik_HucT1fMjHcmz6p8qk9etjAZIscnDb-3yLYKe4iEDvV-r74t5qgyt9HN\" alt=\"\" width=\"372\" height=\"280\"\/><\/figure><\/div>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Why did you choose this area of research?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The applications of nematode-bacteria symbiont are potential biocontrol technology for managing agricultural pests.
