Laboulbeniales (Ascomycetes) of Finland and adjacent parts of the U.S.S.R.
- L. Huldén
Investigation of the occurrence of ectoparasitic,laboulbeniaceous fungi in Finland and adjacent parts of the U.S.R. found 166 species of insects to be infested by 88 taxa of Laboulbeniales, all of which are reported from the area for the first time. Expand

Activation of the hypnozoite: a part of Plasmodium vivax life cycle and survival
It is proposed that a relapse of vivax malaria, besides being genetically determined by the specific strain, is induced by the bites of uninfected vectors, and artificial triggering of hypnozoites would make the medication more effective and resistance against a protein that the parasite itself uses during its life cycle would not develop.

Significance of spring migration and flexibility in flight‐muscle histolysis in waterstriders (Heteroptera, Gerridae)
Abstract. 1. Individuals of long‐winged waterstrider (Gerridae) species were found in spring far from their breeding habitats, which indicates that they fly before reproduction.
Establishing a community‐wide DNA barcode library as a new tool for arctic research
This study establishes the to‐date most comprehensive library of DNA barcodes for a terrestrial site, including all known macroscopic animals and vascular plants of an intensively studied area of the High Arctic, the Zackenberg Valley in Northeast Greenland, to demonstrate its utility. Expand
Endemic malaria: an 'indoor' disease in northern Europe. Historical data analysed
Northern malaria existed in a cold climate by means of summer dormancy of hypnozoites in humans and indoor transmission of sporozoites throughout the winter by semiactive hibernating mosquitoes. Expand
The decline of malaria in Finland – the impact of the vector and social variables
It appears that malaria in Finland was basically a social disease and that malaria trends were strongly linked to changes in human behaviour and that decreasing household size caused fewer interactions between families and accordingly decreasing recolonization possibilities for Plasmodium. Expand
Dynamics of positional warfare malaria: Finland and Korea compared
The malaria peak during the positional warfare in the 1940's was a short outbreak during the last phase of declining indigenous malaria in Finland, and the activation of hypnozoites among a large number of soldiers and subsequent medication contributed to diminishing the reservoir of malaria and speeded up the eradication of the Finnish malaria.

Checklist of the family Culicidae (Diptera) in Finland
A checklist of the Culicidae (Diptera) recorded from Finland is provided and it is found that the majority of the species recorded are new records. Expand
