The vulva of the nematode is located at the front tip of the body close to the mouth. The only free-living stage is the egg and all other stages live in the body cavity of the host. First instar sandfly larvae become infected by ingesting nematode eggs; 2nd, 3rd and 4th instars are not susceptible. The infective juvenile worms hatch in the mid-gut of the sandfly larva and migrate through the gut wall into the haemocoel where they complete their development. After mating, female nematodes begin to develop quickly while the males shrink and die. Female nematodes are fully mature after 37 days of infection by the time the adult flies emerge from pupae, at which stage they bore a hole through the cuticle of the abdomen of the imago to expose the vulva and lay eggs. The eggs survive for two and a half years in humid larval frass, but almost all die within two weeks in water. The development of infected larvae is retarded and, compared to uninfected larvae, significantly fewer survive to the imago stage. Infection causes an inversion in the normal pattern of emergence of sandflies with more females than males emerging in the first three days. P. duboscqi, a sandfly closely related to P. papatasi, is susceptible to infection, but sandflies of the subgenus Larroussius do not fully support the development of the parasite.","PeriodicalId":18988,"journal":{"name":"Nematologica","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1997-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81186764","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

T. gracilis comprised 3.5% of all nematodes in the littoral, 6.3% in the littoriprofundal and 2.7% in the profundal. T. medius comprised 0.3% of all nematodes in the littoral, 1.4% in the littoriprofundal and 3.3% in the profundal. The species contributed to a considerable portion of nematode biomass in Lake Konigssee. Mean yearly biomass of T. gracilis was greatest at 1 m depth (0.52 mg/100 cm 2 ww; 65% of total nematode biomass) and of T. medius at 60 m depth (0.2 mg/100 cm 2 ww; 49% of total nematode biomass). Density of T. gracilis peaked twice a year in 1 m water depth (winter and summer) and once in deeper regions (winter/spring). T. medius peaked once a year in 10 m depth (spring), showed no distinct maximum in 30 m depth and reached higher numbers in 60 m depth in winter. There was considerable water depth- and time-dependent variation in sex ratios of T. gracilis. The main reproductive period seemed to be different for the investigated depths. The proportion of individuals of T. gracilis in the top sediment layer was about 57% and of T. medius about 72%. Juveniles and adults of T. gracilis were partially segregated in the sediment column. Morphometric data of both species revealed sexual dimorphism in size, body shape and weight.","PeriodicalId":18988,"journal":{"name":"Nematologica","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1997-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87434453","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
