  abstract = {{Q}uiescent conidia of {I}saria fumosorosea were submitted to various wetting-drying cycles under different regimes of temperature and air humidity. {G}ermination and viability of conidia collected on cultures freshly host-passed ({P}2) were not affected at 25 degrees {C} during five cycles at increasing wet phase duration (2-12 h per daily cycle) under any moisture conditions (13-86% {RH}). {I}nfectivity levels remained stable, but mortality was slightly postponed. {I}n vitro-cultured inocula ({P}5) were significantly affected after only one cycle at higher air humidity (75 and 86% {RH}) and temperature (35 and 40 degrees {C}). {T}he persistence of {I}. fumosorosea conidia suspended in water soluble extracts of leaf surfaces (corn and cabbage) confirmed the better persistence of {P}2 conidia and the relatively higher detrimental effect of lower air humidity conditions when combined with moderate temperatures. {Q}uiescent conidia deposited in situ on potted plants of cabbage showed a higher persistence on wet foliage and on foliage submitted to wetting-drying cycles, than on dry foliage. {T}hese results underline that constraints prevailing in targeted environments and ecological fitness of fungal isolates have to be taken into account for assessing microbial control strategies.},
