We construct an explicit expression of positive steady-state solution using the implicit function theorem and prove its linear stability. Moreover, by applying feedback time delay [Formula: see text] as the bifurcation parameter, spatially inhomogeneous Hopf bifurcation near the positive steady-state solution is proved when [Formula: see text] is varied through a sequence of critical values. This finding implies that feedback time delay can induce spatially inhomogeneous periodic oscillatory patterns. The direction of spatially inhomogeneous Hopf bifurcation is forward when parameter [Formula: see text] is sufficiently large. We present numerical simulations and solutions to further illustrate our main theoretical results. Numerical simulations show that the period and amplitude of the inhomogeneous periodic solution increase with increasing feedback time delay. Our theoretical analysis results only hold for parameter [Formula: see text] when it is sufficiently close to 1, whereas numerical simulations suggest that spatially inhomogeneous Hopf bifurcation still occurs when [Formula: see text] is larger than 1 but not sufficiently close to 1. <\/jats:p>","DOI":"10.1142\/s0218127423500876","type":"journal-article","created":{"date-parts":[[2023,6,16]],"date-time":"2023-06-16T09:02:56Z","timestamp":1686906176000},"source":"Crossref","is-referenced-by-count":2,"title":["Spatiotemporal Patterns of a Host-Generalist Parasitoid Reaction\u2013Diffusion Model"],"prefix":"10.1142","volume":"33","author":[{"given":"Zhan-Ping","family":"Ma","sequence":"first","affiliation":[{"name":"School of Mathematics and Information Science, Henan Polytechnic University, Jiaozuo, Henan 454003, P.
