Changes in vegetation complexity during the development of rice ecosystems affect orb-weaving spider-prey trophic networks

Original language description

Temporal change in vegetation complexity and field management may interactively affect the structure of predator-prey networks in agroecosystems and consequently alter the biocontrol potential of predators. There is a limited number of studies that have addressed these questions for generalist predator-prey networks. We investigated how vegetation complexity during crop development and management type (conventional vs. organic) affect the trophic networks of orb-weaving spiders and their prey in rainfed lowland rice ecosystems in southern Thailand. Specifically, we investigated orb-weaving spiders and prey composition, prey selectivity and network structure. Overall, orb-weaving spiders captured mostly detritus-associated Diptera, aquatic-associated Ephemeroptera and Hemiptera pests. The increasing vegetation complexity during rice development significantly restructured the network of orb-weaving spiders and prey, while field management had only a marginal effect. The increased vegetation complexity during rice development led to an increased number of weak trophic interactions in comparison to few but strong interactions in simple vegetation. Our results indicate that increasing the number of spider species per prey taxon (prey vulnerability) in late rice season may enhance their top-down control of prey including rice pests. This study also highlights that the network complexity and the stability of rice ecosystems increased during the rice growing season as the vegetation became more complex. Future practices could look for a way to support the densities of detritus and aquatic insects and to artificially increase habitat complexity during the early stage of rice development to improve the biocontrol services provided by the orb-weaving spiders.
