However, few studies have investigated the influence of plant trichomes on the population dynamics of soybean herbivores and their natural enemies. We conducted a field survey to investigate whether soybean trichomes affected the abundance of herbivores and their predators. The results of this study show that moderately or densely pubescent trichomes have positive influences on the abundance of some herbivores （e.g., Stollia guttiger） and predators （e.g., Propylaeajaponica and Orius similes） although the influence may change over time, while trichome types do not affect the density of soybean aphid, Aphis glycines.展开更多
