窗胸萤生物学特性及其幼虫肠道细菌种类的研究

Studies on the Biology of Pyrocoelis analis and the Intestinal Bacteria of P.analis Larvae

对一种陆栖萤火虫窗胸萤(Pyrocoelis analis Fabricius)的生物学特性及其幼虫的肠道细菌进行了研究。结果表明:窗胸萤在24℃下从卵发育到成虫平均(349.50±8.15)d,其卵期、幼虫期、蛹期及成虫期分别为(117.22±0.90)d、(184.92±18.56)d、(12.65±1.09)d和(15.60±3.85)d;在其5龄幼虫中分离纯化出埃希氏菌属(Escherichia)、金色单胞菌属(Chryseomonas)、放线杆菌属(Actinobacillus)、摩根氏菌属(Morganella)、李斯特菌属(Listeria)、金杆菌属(Aureobacterium)、微杆菌属(Microbacterium)、地杆菌属(Terrabacter)、芽孢杆菌属(Bacillus)和黄杆菌属(Flavibacterium)共10个细菌菌株。

The biology characteristics and the larvaes’ intestine bacteria of Pyrocoelis analis were studied, results of identification was that the development duriation from eggs to adults were(349.50±8.15) d on the average,which the period of eggs,larvars,pupasand adluts stage were(117.22±0.9) d, (184.92±18.56) d,(12.65±1.09) d and(15.60±3.85) d respectively at 24℃,the other was that ten bacteria strains were isolated from the intestine of the 5th instar larvae of P.analis,and were identified as Escherichia,Chryseomonas,Actinobacillus,Morganella,Listeria,Aureobacteriu,Microbacterium, Terrabacter,Bacillus and Flavibacterium.
