Opis:
Several-years' studies on the dynamics of occurrence of Anopheles labranchiae atroparvus larvae in the environs of Gdańsk proved it to have been conditioned by the external temperature, abundance of atmospheric precipitations and surface of the breeding ground. Most larvae were collected in July and August, those of the Ist instar prevailing; they carne from the most fertile summer generations of Iemales. The occurrence of the IVth instar larvae in reservoirs was followed by hatching of mature forms only a few days later. Most larvae in the IVth instar were noted in May, as well as August or September. When controlling the Anopheles larvae it should be considered that the best period for the control is May and August or September, as most of the IVth instar larvae are then in the breeding ground.

Opis:
As a result of a survey of 362 birds, data were accumulated concerning the influence of migration and seasonal distribution of the Protozoa of the genus Plasmodium, Haemoproteus, Leucocytozoon and Lankesterella and Microfilariae. Material for study consisted of blood films which had been collected over two years. The smears were stained with Giemsa stain and each was examined approximately twenty minutes. The monthly incidence of infections is shown in Table 1. Plasmodium was found in 8.3 per cent of all atudied birds, from March to December with the highest intensity during the summer period. The non-migratory birds were infected in 81 per cent (of all infected with Plasmodium birds). Haemoproteus was established in 6.4 per cent from April to October. In majority this protozoan was found in migratory birds (70 per cent of all infected with Haemoproteus birds). The most popular in Poland are the protozoans of the genus Lankesterella and Leucocytozoon. These two genus were found in Poland through the all years. Leucocytozoon was found in 12.4 per cent. In majority this parasite was established in birds of the family Corvidae (78.5 per cent of all infected with Leucocytozoon birds). Corvus frugilegus was caught in majority in the winter period and it was infected in 57.7 per cent. It is interesting because the birds, which are in winter in Poland were coming from north and east. Microfilariae were found through the all year and 50 per cent of Corvidae were infected with this parasite.

Opis:
The present study deals with the ecology of Lyme borreliosis in Northern Poland. The complexity of environmental conditions are: (1) the presence of certain rodent hosts for the Borrelia, (2) the seasonal patterns of abundance and infection rate of /. ricinus in the population of rodents and on vegetation, (3) the prevalence of B. burgdorferi s.1., B. garinii and B. afzelii. The longterm studies were carried out on a monthly basis from April to October (1998-2001) in woodlands at Urwitałt near Mikołajki on the Mazury Lakes. Two methods of spirochate detection were used: indirect immunofluorescence assay (IFA) and polymerase chain reaction (PCR). The dynamics of ticks infestation, differences in infestation rates between years, months, age and sex for two species of rodents (Clethrionomys glareolus, Apodemus flavicollis) were analysed using the software package Statgraphics version 7 and GLIM 4 (statistical system for generalized linear interactive modeling, Royal Statistical Society 1993). We were able to demonstrate that in selected habitat of Mazury Lakes the spirochaetal agent of Lyme borreliosis occurs quite frequently, both in rodents and in vector — /. ricinus. Comparing C. glareolus and A. flavicollis, each rodent species showed different, seasonal and sex dependent, host infection with Borrelia. Due to the courses of prevalence of infection, both for partially engorged ticks and questing ticks, the risk of human infection seems to be highest in spring. The infection rate of engorged larvae was much higher than in questing larvae. We conclude that both species of rodents, highly abounded in the Mazury Lakes district, may represent significant zoonotic reservoir for B. burgdorferii sl., B. garinii and B. afzelii.
