产品描述:
Piericidin B is a bacterial metabolite that has been found in S. mobaraensis and has insecticidal and antimicrobial activities.{61379,61380,61381} It inhibits NADH oxidase activity in isolated bovine heart mitochondria and inhibits respiration in isolated rat liver mitochondria and isolated cockroach (P. americana) muscle mitochondria.{61380,61381} Topical application of piericidin B (4 µg/insect) induces mortality in 87.5% of houseflies (M. domestica).{61379} It induces 93.3, 100, and 100% mortality in rice stem borer (C. simples), silkworm (B. mori), and green caterpillar (P. rapae) larvae, respectively, when applied at respective concentrations of 60, 4.8, and 96 µg/larva. Piericidin B is active against the fungi T. asteroides, T. rubrum, M. gypseum, and C. neoforms (MICs = 20, 10, 20, and 2 µg/ml, respectively), as well as the bacteria M. luteus and P. vulgaris (MICs = 50 and 100 µg/ml, respectively).
