Effects of insect cuticular fatty acids on in vitro growth and pathogenicity of the entomopathogenic fungus Conidiobolus coronatus

Composition and antimicrobial activity of fatty acids detected in the hygroscopic secretion collected from the secretory setae of larvae of the biting midge Forcipomyia nigra (Diptera: Ceratopogonidae)

“…The antimicrobial action of free fatty acids in combination has not been thoroughly examined. But composition of cuticular fatty acids -the dominant component of epicuticular lipids (Pedrini et al, 2007), which can be treated as a mixture (which concurs with the results of our studies), erects an effective barrier to microbial penetration in insects (Smith and Grula, 1982;Boguś et al, 2007;Gołę biowski et al, 2008aGołę biowski et al, , 2010Gołę biowski et al, , 2011Boguś et al, 2010). Benkendorff et al (2005) carried out an assay similar to ours using lipid mixtures for testing antibacterial activity.…”

The antimicrobial activity of the alcohols fromMusca domestica

“…Other free fatty acids present on the surface of H. zea and S. frugiperda also present mycostatic activity towards fungi (Smith and Grula, 1982). The current state of knowledge on diverse, species-specific effects of free fatty acids on the growth and virulence of insecticidal fungi is reviewed by Boguś et al (Boguś et al, 2010).…”

“…Entomopathogenic fungi have the ability to degrade insect cuticular lipids with hydrocarbons, the preferred components capable of supporting fungal growth (Napolitano and Juárez, 1997). Although several aspects of the interaction between entomopathogenic fungi and insect host cuticular hydrocarbons and fatty acids have been examined (Pedrini et al, 2007;Boguś et al, 2010), there is no information concerning the other surface compounds.…”

Wing wettability of Odonata species as a function of quantity of epicuticular waxes

“…Superhydrophobicity and self-cleaning properties are also two important characteristics possessed by many insects. In order to maintain their high levels of functionality, their surfaces have evolved to possess highly specific structures and surface chemistries [12][13][14][15][16][17][18][19]. Dragonfly and damselfly species belong to the order Odonata, and their wing surfaces are known for their superhydrophobicity and self-cleaning properties.…”
