Screening of Metarhizium and Beauveria spp. conidia with exposure to simulated sunlight and a range of temperatures

Storage of Beauveria bassiana Conidia Suspension: A Study Exploring the Potential Effects on Conidial iability and Virulence against Dermanyssus gallinae De Geer, 1778 Acari: Dermanyssidae

“…Previous studies suggest that temperature, humidity and spore moisture content can all influence the viability of entomopathogenic fungi during long-term storage [12][13][14][15][20][21][22][23]. Low temperature, i.e., <5°C, as well as low spore moisture content <5%, ensure fungal viability [12,15,20,24], and promote faster development of the fungus, due to higher production of ATP [15,25]. In this study, storage at 4 ± 1°C provided the best vitality of B. bassiana CIS, with no significant reduction in CFU detected over five months.…”

“…However, conidial viability decreased rapidly when exposed to UV light (Zimmermann 1982;Morley-Davies et al 1995). In a conidial viability experiment using a sunlight simulator at 40 0 C, germination ranged between 10 and 50% after 24 hrs of exposure to UV (Morley-Davies et al 1995).…”

Sensibilidade de isolados de fungos entomopatogênicos às radiações solar, ultravioleta e à temperatura

“…Na maioria dos estudos realizados com fungos filamentosos observou-se redução acentuada da viabilidade dos conídios após curtos períodos de exposição à radiação solar ou radiação UV. Conídios de B. bassiana, M. anisopliae e Metarhizium flavoviride Gams & Rozsypal diminuiram acentuadamente a viabilidade com o aumento do período de exposição à radiação UV incidente de simulador solar (Morley-Davies et al, 1996). Conídios das linhagens ARSEF 23 e ARSEF 25 de M. anisopliae expostos diretamente à radiação solar por apenas 4 horas ficaram totalmente inativos (Braga et al, 2001c).…”
