The Cordyceps genus includes many species of fungi, most of which are endoparasitoids on arthropods.The distribution of these fungi is cosmopolitan, but many occur in regions such as Asia with a hot, humid climate. These pathogens of insect pests are promising candidates for use as biological control factors. Entomopathogenic fungi including the famous Cordyceps sinensis produce bioactive compo...

Ixodes scapularis Say adults, nymphs, and larvae were treated with the entomopathogenic fungus Metarhizium anisopliae in a combination of field and laboratory experiments to assess sublethal effects of the fungus on I. scapularis fecundity and body mass. Postengorgement and egg mass weights were 33 and 50% lower, respectively, in adult females treated with M. ansiopliae in the field before engo...

Three new 10-membered macrolides (1-3) have been isolated from the entomopathogenic fungus Cordyceps militaris BCC 2816, together with six known compounds, cepharosporolides C (4), E (5), and F (6), 2-carboxymethyl-4-(3'-hydroxybutyl)furan (7), cordycepin (8), and pyridine-2,6-dicarboxylic acid. The structures were determined by analysis of NMR data, and an X-ray analysis was performed to confi...
