A fungal epizootic in populations of Fiorinia externa Ferris (Hemiptera: Diaspididae) infesting hemlock trees, Tsuga canadensis (L.) Carrière (Pinales: Pinaceae) in forests of the Northeastern US has been recently detected. The current known distribution of the epizootic spans 36 sites in New York, Pennsylvania, New Jersey and Connecticut. Colletotrichum acutatum Simmonds var. fioriniae Marcelino and Gouli var. nov. inedit. (Phyllachorales: Phyllachoraceae) was the most prevalent fungus recovered from infected scales. Bioassays indicated that this C. acutatum variety is highly pathogenic to F. externa. Mortality rates of >90 and >55% were obtained for F. externa crawlers and settlers, respectively. Significantly lower mortality levels,

China is a major producer of pears in the world and anthracnose is the most important disease, which may include fruit rot and early defoliation, and further brings enormous economic losses. In August of 2023, a sudden outbreak of anthracnose disease, ranging from 70% to 90% disease incidence, occurred on fruits of Pyrus pyrifolia (Burm.f.

Managing plant diseases caused by phytopathogenic fungi, such as anthracnose caused by species, is challenging. Different methods have been used to identify compounds with antibiotic properties. strains are a source of novel molecules with antifungal properties, including volatile organic compounds (VOCs), whose production is influenced by the nutrient content of the medium.
