During a helminthological study of waterfowl in China,a new species(Cloacotaenia cygnimorbus ***.)of hymenolepidid cestodes(tapeworm)was found in the small intestine of whooper swan(Cygnus cygnus,Linnaeus,1758).The rudimentary rostellum and four unarmed muscular suckers,proglottids with distinct craspedote and three spherical testes were coincident with the characters of Cloacotaenia or hymenolepis,but phylogenetic analysis of 28S rRNA and cox1 gene revealed that the new species is Cloacotaenia rather than *** morphology was also clearly diff erentiated from *** in the arrangement of its testes in a triangle instead of in line and the cirrus unarmed rather than *** with ***,the new species has more elongated neck,much larger mature proglottids and much smaller testes,cirrus sac,ovary,vitellarium and uterine *** addition,it infected the host intestine not the *** analysis of cox1 gene of the new species shows that it had a level of sequence variation(10.52–23.06%)with the sequences of *** considerable morphological and molecular diff erences between those two parasites support *** *** a new species.

Do male and female beetles (Tenebrio molitor) respond differently to rat feces containing eggs from the tapeworm, hymenolepis diminuta?

引用

Natural Science 2010年第8期2卷 855-859页

作者： John F. Shea 不详

Males and females often differ in their susceptibility and exposure to infection. Thus, they may also differ in their ability to avoid infection. The beetle, Tenebrio molitor, risks infection with cysticercoids when ingesting rat feces containing eggs of the tapeworm, hymenolepis diminuta. Previous studies demonstrated that beetles sometimes prefer infective feces suggesting that the tapeworm influences the foraging behavior of beetles. After recording beetle movement in an arena containing infective and uninfective feces for one hour, sex main effects were not significant, but the effect of sex asked in trials was significant for males. Specifically, more male beetles occurred on the uninfective bait than on the infective bait. This observation suggests that male beetles avoid infective feces, which decreases their probability of infection with H. diminuta. If the cost of infection is higher in males, then selection to avoid infective feces may act more strongly on males.

本文首次报告我国家鸭的副小体膜壳绦虫(hymenolepis paramicrosoma Gasowaka,1913)的生活史。实验阐明福建厦门地区的广布中剑水蚤(Mesocyclops leuckarti)和等形小剑水蚤(Microcyclops ***)为本虫的中间宿主,二者均是中间宿主新记录。在室温23—26℃的条件下,剑水蚤自感染虫卵后发育为拟囊尾蚴期需时7天,但达到成熟的拟囊尾蚴则需11天,幼虫在中间宿主体内的全程发育要经过六钩蚴期、原腔期、囊腔期、头结形成期和拟囊尾蚴期等五个阶段的发育。小鸭感染拟囊尾蚴后需要经过15天才可发育达到性成熟的成虫。
