RETRACTED ARTICLE: Assessment of insecticidal activity of red pigment produced by the fungusBeauveria bassiana

Microbial polyketides and their roles in insect virulence: from genomics to biological functions

“…4), a red 1,4-bibenzoquinone pigment, can be isolated from B. bassiana [129][130][131] and B. brongniartii. 132 Oosporein shows a broad range of biological activities such as antiviral, 133 antibiotic, 134 antifungal, 135 and insecticidal 136 activities. Oosporein helps fungi to compete with other microorganisms in insect cadavers.…”

“…Oosporein helps fungi to compete with other microorganisms in insect cadavers. 136 It also caused a change in erythrocyte morphology and cell lysis by inhibiting ATPase activity in erythrocyte membranes. 137 Oosporein serves as a serine proteinase inhibitor in G. mellonella and H. abietis larvae, blocking PPO activation and inhibiting melanization.…”
