ABSTRACT The geographic mosaic of coevolution predicts reciprocal selection, the first step in coevolution, to vary with changing biotic and abiotic environmental conditions. Studying how temperature affects selection is essential connect effects global warming on microevolutionary patterns ecological processes underlying them. In this study, we investigated whether influenced between a plant ( Brassica rapa ) its pollinating butterfly herbivore Pieris rapae ). two environments (ambient hot), measured phenotypes plants butterflies, their interactions fitness, which used calculate selection. We found variety traits involved ambient environment, but none hot environment. provide experimental evidence that elevated weakens will help better predict consequences for coevolution.

Abstract BACKGROUND For most insect herbivores, where females decide to lay their eggs has a significant impact on offspring survival. Although females’ behavior is essential for oviposition site selection, it unclear what role the egg itself in this process. RESULTS Two closely related spittlebugs, Callitettix versicolor and Abidama liuensis , with diametrically opposite colors, were selected investigate whether color vital selection. Both spittlebugs preferred side of substrate that had more light. Eggs laid by C. substrates positioned significantly higher than A. . A position meant light ultraviolet (UV) radiation. Accordingly, different colors these two resulted resistance abilities toward UV eggs, which are black, tolerant radiation white The difference between spittlebugs’ caused melanin compositions. tolerance allows occupy space Consequently, density was CONCLUSION This study revealed species use segregate same host plant, ensuring coexistence habitat. results also provide behavioral ecological basis prevention control strategies pests. © 2025 Society Chemical Industry.
