Both abiotic and biotic factors can mold insect-plant interactions. Using the electrical penetration graph (EPG) technique, Nalam and colleagues demonstrate that the potato psyllid, Bactericera cockerelli ( Sulc) (Hemiptera: Triozidae), alters its feeding behavior when infected with the bacterial pathogen Candidatus Liberibacter solanacearum, depending on the water supply of the tomato host plants. The elegant study highlights the complex interaction between the feeding behavior of an herbivorous insect – an important vector of the bacterium causing zebra chip disease – and the condition of its plant host.

非生物和生物因素都可以塑造昆虫与植物的相互作用。使用电穿透图 (EPG) 技术，Nalam 及其同事证明，马铃薯木虱 Bactericera cockerelli (Sulc)（半翅目：Triozidae）在感染细菌病原体 Candidatus Liberibacter solanacearum 时会改变其摄食行为，这取决于马铃薯木虱的供水情况。番茄寄主植物。这项优雅的研究强调了食草昆虫的摄食行为（一种导致斑马片病的细菌的重要载体）与其植物宿主状况之间的复杂相互作用。
