[Entomophthorosis of Culex pipiens (Culicidae) mosquitoes breeding in basements]. | Foci of mycosis of C. p. pipiens and C. p. molestus caused by the parasitic fungus Entomophthora conglomerata Sorok. were found out in basements flooded with water. The conditions prevailing in the foci, sites of infection of mosquitoes and seasonal changes in the epizootic process are described. Developmental periods ... | 571,593 | [
