Checklist of Dejean from America (Meloidae, Meloinae, Epicautini).

This paper presents a comprehensive list of American . Two hundred and sixty-four named species were recorded in this checklist based primarily on literature and museum records. Seventy-two species were included in the subgenus Macrobasis and 192 species into the nominotypic subgenus.

Antifungal metabolites from Schinopsis balansae Engl (Anacardiaceae): isolation, identification and evidences of their mode of action on Fusarium graminearum Schwabe.

An antifungal activity-directed fractionation of leaf constituents from Schinopsis balansae on Fusarium graminearum yielded a fraction mainly made of a mixture of four 3-n-heptadec(en)ylcatechols (PALK). The PALK fraction showed on macroconidia germination a MIC value of 500 μg/mL which was twofold higher than that required for prothioconazole (MIC = 250 μg/mL). Sublethal concentrations of PALK modify the morphogenesis in germinating macroconidia, and decreased fungal production of HO and deoxynivalenol biosynthesis at early fungal growth.
