“…Insects are rapid adaptive organisms with various magical dynamic behaviors, which can be diametrically different between populations with high and low growth rates [ 1 , 2 ]. Many insects have nonoverlapping generations, shaping discrete dynamics [ 3 , 4 ]. The dynamics of insect populations are not only influenced by various abiotic factors, such as temperature [ 5 , 6 ], altitude [ 7 ], and humidity [ 8 ], but also largely mediated by predator–prey interactions [ 9 , 10 ].…”

The insect predator–prey system mediates several feedback mechanisms which regulate species abundance and spatial distribution. However, the spatiotemporal dynamics of such discrete systems with the refuge effect remain elusive. In this study, we analyzed a discrete Holling type II model incorporating the refuge effect using theoretical calculations and numerical simulations, and selected moths with high and low growth rates as two exemplifications. The result indicates that only the flip bifurcation opens the routes to chaos, and the system undergoes four spatiotemporally behavioral patterns (from the frozen random pattern to the defect chaotic diffusion pattern, then the competition intermittency pattern, and finally to the fully developed turbulence pattern). Furthermore, as the refuge effect increases, moths with relatively slower growth rates tend to maintain stability at relatively low densities, whereas moths with relatively faster growth rates can induce chaos and unpredictability on the population. According to the theoretical guidance of this study, the refuge effect can be adjusted to control pest populations effectively, which provides a new theoretical perspective and is a feasible tool for protecting crops.
