| 摘 要： | 非线虫共生细菌 (Bacillussubtilis ,B .thuringiensis,Pseudomonasfluorescens ,Micromonosporapur purea,Rhizopusdelemar ,Pseudomonasaeruginosa ,Streptomycesvenezuelae ,Streptomycesantibioticus ,Penicilliumcitrnum ,Ganodermalucidum ,Agaricusbisporus,Pleurotusostreatus,Rhizobiumlegumi unosarum和Photobacteriumphosphoreum)的培养液以及其上清液、斜纹夜蛾 (Spodopteralitura)昆虫细胞系用于引诱无菌SteinernemacarpocapsaeA2 4和HeterorhabditisbacteriophoraH0 6发育。上述培养物均未能诱导H .bacteriophoraH0 6发育。虽然P .phosphoreum菌液可致死A2 4线虫 ,但是其上清液可诱导线虫发育。无菌S .carpocapsaeA2 4线虫可利用斜纹夜蛾昆虫细胞繁殖 ,产生下一代感染期线虫。结果进一步说明 ,引诱H .bacteriophoraH0 6发育的化学信息物质比S .carpocapsaeA2 4的专一。

| Abstract: | Axenic Steinernema carpocapsae Agriotos (A24) and Heterorhabditis bacteriophora H06 dauer juveniles were exposed to Spodoptera litura insect cell cultures, and the cell free filtrates or cells of different non symbiotic microorganism cultures, including Bacillus subtilis, B. thuringiensis, Pseudomonas fluorescens, Micromonospora purpurea, Rhizopus delemar, Pseudomonas aeruginosa, Streptomyces venezuelae, Streptomyces antibioticus, Penicillium citrnum, Ganoderma lucidum, Agaricus bisporus, Pleurotus ostreatus, Rhizobium legumiunosarum, and Photobacterium phosphoreum. None of these cell free filtrates or cultures, or insect cell culture triggered recovery of H. bacteriophora H06. However, cell free filtrate of P. phosphoreum induced recovery of S. carpocapsae A24, although the cell culture of this bacterium kill the A24 dauer juveniles before recovery. S. litura insect cells provided the nutrients for axenic S. carpocapsae A24 nematode growth and next generation of dauer juveniles were observed. These results further demonstrated that food signals were much more specific to H. bacteriophora than to S. carpocapsae. |
