“…I. fumosorosea SFP-198 was developed as a mycopesticide by Dongbu Hannong in Korea to control greenhouse pests [22]. The fungus was propagated on quarter strength Saubraud dextrose agar (1/4 SDA) (pH 6.0) at 25 ± 1℃ in the darkness for 14 days as a seed culture for this study [23].…”

Entomopathogenic fungi are promising pest-control agents but their industrial applicability is limited by their thermosusceptibility. With an aim to increase the thermotolerance of Isaria fumosorosea SFP-198, moisture absorbents were added to dried conidial powder, and the relationship between its water potential and thermotolerance was investigated. Mycotized rice grains were dried at 10℃, 20℃, 30℃, and 40℃ and the drying effect of each temperature for 24, 48, 96, and 140 hr was determined. Drying for 48 hr at 10℃ and 20℃ reduced the moisture content to < 5% without any significant loss of conidial thermotolerance, but drying at 30℃ and 40℃ reduced both moisture content and conidial thermotolerance. To maintain thermotolerance during storage, moisture absorbents, such as calcium chloride, silica gel, magnesium sulfate, white carbon, and sodium sulfate were individually added to previously dried-conidial powder at 10% (w/w). These mixtures was then stored at room temperature for 30 days and subjected to 50℃ for 2 hr. The white carbon mixture had the highest conidial thermotolerance, followed by silica gel, magnesium sulfate, and then the other absorbents. A significant correlation between the water potential and conidial thermotolerance was observed in all conidia-absorbent mixtures tested in this study (r = -0.945). Conidial thermotolerance in wet conditions was evaluated by adding moisturized white carbon (0~20% H2O) to conidia to mimic wet conditions. Notably, the conidia still maintained their thermotolerance under these conditions. Thus, it is evident that conidial thermotolerance can be maintained by drying mycotized rice grains at low temperatures and adding a moisture absorbent, such as white carbon.

“…Many studies have evaluated the efficacy of a combination of inert materials, such as diatomaceous earths, with different species of fungi, such as B. bassiana , I. fumosoroseus and M. anisopliae . Combinations of mycoinsecticides and sublethal doses of insecticides, which were selected on the basis of biological compatibility with the fungal agent involved, have been successful in increasing mortality in some insect pests . Fungal formulations and insecticides may act synergistically, allowing the use of lower concentrations in both cases and minimising environmental pollution.…”

Complementary effect of Phloxine B on the insecticidal efficacy of Isaria fumosorosea SFP-198 wettable powder against greenhouse whitefly, Trialeurodes vaporariorum West.

Abstract: Phloxine B cooperates with SFP-198 WP complementarily, possibly in the order of killing action (early: Phloxine B; late: SFP-198 WP). The dye can be incorporated into SFP-198 WP to improve its efficacy and applied to other Hypocrelean entomopathogenic fungal products.
