There have been numerous investigations of parasite local adaptation, a phenomenon important from the perspectives of both basic and applied evolutionary ecology. Recent work has demonstrated that temperature has striking effects on parasite performance by mediating trade-offs in parasite life history and through genotype x environment interactions. To test whether parasite local adaptation is ...

Powdery mildews (Erysiphales) are economically important plant pathogens that attack many agricultural crops. Conventional management strategies involving fungicide application face challenges, including the evolution of resistance and concerns over impacts on non-target organisms, that call for investigation of more sustainable alternatives. Mycophagous ladybird beetles (Coleoptera: Coccinelli...

In October 2022, common Asian cowpea (<i>Vigna nakashimae</i>) powdery mildew disease was investigated at Yesan-gun, Chungcheongnam-do, Korea (36°40’12.7"N,126°51’36.4"E). The mainly occurred on the front of leaves, and weak back side leaf. chasmothecia identified Analysis internal transcribed spacer rDNA sequence 28S large subunit sequence, along with morphological characteristics ...

Trade-offs in life-history traits is a central tenet in evolutionary biology, yet their ubiquity and relevance to realized fitness in natural populations remains questioned. Trade-offs in pathogens are of particular interest because they may constrain the evolution and epidemiology of diseases. Here, we studied life-history traits determining transmission in the obligate fungal pathogen, Podosp...
