pH

In general Entomophthorales are tolerant of pH levels between 6 and 7 with an optimum of approximately 6.5 for the species investigated so far. At pH below 5 and above 8 growth is remarkably depressed (Gustafsson, 1965; Latgé et al. 1977; Dunphy & Nolan, 1979; Latgé & Sanglier, 1985; Robinson, 1986). For P. neoaphidis the fastest growth rate has been obtained between pH 6.0 and 7.0 (Gustafsson, 1965; Robinson, 1986). The optimal pH corresponds well with the pH usually found in insect haemolymph. Gustafsson (1965) concluded that P. neoaphidis has a relatively narrowly limited pH optimum compared with species from the genus Conidiobolus.

Maybe I missed something trivial here
Pandora, to the best of my knowledge, are entomopatogenic fungi beloinging to
the Zygomycota.
Thanks
