笔者从中科院获悉,该院动物研究所孙江华研究组赵莉蔺副研究员等最新研究表明,松材线虫转型发育与其媒介昆虫—松墨天牛羽化过程高度偶联是松材线虫扩散的关键。松材线虫具有两个扩散周期虫态:扩散型三龄线虫(LⅢ)形成扩散型四龄线虫(LIV)。松墨天牛在羽化过程中释放大量C15-C18脂肪酸乙酯,启动松材线虫Insulin和DA/DAF-12信号通路,改变发育途径,进而诱导扩散型三龄线虫(LⅢ)形成扩散型四龄线虫(LIV)。只有扩散型四龄线虫(LIV)能够被媒介天牛携带并
The author learned from the Chinese Academy of Sciences, the Institute of Animal Research Sun Jianghua research group researcher Zhaoli Lin and other recent studies have shown that the pine wood nematode transformation and development of its vector insect - Monochamus alternatus emergence process is the key to the proliferation of pine wood nematode. Bursaphelenchus xylophilus has two stages of spreading cycle: the diffusible third instar nematode (LIV) is formed by the diffusible third stage nematode (LIII). Monochamus alternatus released a large amount of C15-C18 fatty acid ethyl ester during the eclosion, initiated the Insulin and DA / DAF-12 signaling pathways of pine wood nematode, changed the developmental pathway, and then induced the proliferation of the third instar nematode (LⅢ) Nematode (LIV). Only the diffusible fourth instar nematode (LIV) can be carried by the media cephalopods
