Abstract:
... The mycoparasitic fungus Paraphaeosphaeria minitans (formerly Coniothyrium minitans), is increasingly used by farmers to reduce soilborne inoculum of Sclerotinia sclerotiorum. In France, its field efficacy tends to be higher in the North than in the South, leading to the hypothesis of possible regional differences in the susceptibility of the pathogen to the biocontrol agent. A standardized assay ...
... 1. Feeding behaviour of generalist and specialist predators is determined by a variety of trophic adaptations. Specialised prey‐capture adaptations allow specialists to catch relatively large prey on a regular basis. As a result, specialists might be adapted to exploit each item of prey more thoroughly than do generalists. 2. It was expected that obligatory specialist cursorial spiders would feed ...
