Detection of functional plants in relation to the population dynamics of natural predators and pests
Emerging ecological regulation techniques are important measures for natural enemy habitat management using non-crop plants.In order to screen suitable functional plants to increase the effectiveness of predatory natural enemies,and thus improve the control effect of natural enemies on pests in agricultural ecosystems,we monitored and investigated the temporal dynamics of arthropods communities in 15 functional plants.Then the accumulations,the predator-herbivore ratio as well as the relationship between dominant groups of natural enemies and phytophagous pests,and the temporal dynamics were compared.The results showed that Vigna radiata,Medicago sativa,Ricinus communis,Brassica alboglabra,Ocimum basilicum and Sesamum indicum had a greater accumulation of predators and predator-herbivore ratio than other plants.Meanwhile,these predators were clearly correlated with herbivore and temporal dynamics.These were could be used as functional plants in habitat management,which were beneficial to the dominant natural enemies Chrysoperla sinica,Harmonia axyridis and so on.This study provides the basis and new ideas for further detection of functional plants used in conservation biological control.
