The African sweet potato weevil, Cylas puncticollis, and fall armyworm, Spodoptera frugiperda, are insect pests of economic importance that have a negative impact on maize production, respectively. In this study, we aimed to evaluate the potential Melia volkensii extracts protect plants against damage by both pests. We evaluated from bark, leaves, pulp nuts for antifeedant activity C. puncticol...

We investigate the spatial decay and temporal localization properties of quasimodes (i.e., scattering resonances) two-dimensional Vogel spirals, composed deterministic, aperiodic arrays electric dipoles. By determining structural entropy maps spirals using Green's matrix method, we show that three distinctive types coexist in spirals: exponential, power law, Gaussian. While exponential power-la...
