We collaborate with Peter Hämback and other colleagues to study the role of spiders as natural enemies of pests in apple orchards from Sweden and Spain. We used gut metabarcoding for identifying prey species. Most arachnids consume a large range of apple pest species but, surprisingly, also a high proportion of other natural enemies. In fact, a third of prey sequences in spider guts belonged to other predator species. In Spain, among these “preyed predators” were other spiders and mostly heteropteran bugs (mirids and anthocorids). Read the whole paper in Basic and Applied Ecology!
