| Abstract: | Summary Examinations of living and dead larvalPyrausta nubilalis (Hübner) collected in the field over a four-year period indicate that infections caused byPerezia pyraustae
Paillot are widely distributed within populations ofP. nubilalis in Illinois.
Observed fluctuations in the incidence of the parasite among living and dead insects collected in various seasons was taken
as evidence that the disease interacts with temperature to cause mortality in populations of the host.
Résumé Des examens des larves vivantes et mortes dePyrausta nubilalis (Hübner) collectées dans les champs pendant quatre années consécutives indiquent que des infections parPerezia pyraustae
Paillot sont très fréquentes dans les populations deP. nubilalis en Illinois (états-Unis).
Les fluctuations observées dans l'incidence du parasite dans les insectes vivants et morts recueillis pendant plusieurs saisons
montrent que la maladie est influencée par la température, celle-ci occasionnant la mortalité dans les populations de l'h?te.
