Alternaria (entomopathogens) Nees 1817
The genus is wide-spread and includes important plant pathogens. However, several species and strains have been studied as biological control agents of insect pests. This page deals with the latter group.
The species form dark coloured colonies on agar with brown, elliptical conidia often arranged in chains. The condidia are round on the side of the conidiophore and taper into a beak at the apical end. They contain vertical and often also longitudinal septa. The asci, if known, are usually cylindrical with 8 spores.
This page deals only with species causing diseases of insect pests, for other groups see:
