杂色柳叶甲的成虫避开了先前受伤的白柳枝条，转而青睐附近未受伤的枝条。反应迅速，并持续了五天的研究。在短暂的观察期间，绝大多数甲虫进行了运动以外的行为，如取食和休息。此外，甲虫在受伤枝条和未受伤枝条上行走的比例相似。在本实验条件下，先前的伤害并没有显著增加甲虫的搜寻行为。以前受伤的枝条上的叶子比未受伤的枝条上的叶子随后获得的草食更少。这些实验的结果与在野外观察到的草食模式和已知甲虫对受损树叶的食物的生殖反应是一致的。这些结果为理解与取食OFP相关的个体柳树叶片上相对较低的草食水平提供了新的信息。杂七杂八。
Adults of the leaf beetlePlagiodera versicoloraLaich, avoided previously injured shoots ofSalix alba‘Tristis’ in favor of nearby uninjured ones. The response was rapid and persisted for five days of study. During brief periods of observation, the vast majority of beetles engaged in behaviors other than locomotion such as feeding and resting. Furthermore, the proportions of beetles walking were similar on injured and uninjured shoots. It appears that under these experimental conditions previous injury did not greatly increase searching behavior of the beetles. Leaves on previously injured shoots received less subsequent herbivory than uninjured ones. Findings of these experiments are consistent with patterns of herbivory observed in the field and known reproductive responses of beetles to diets of injured leaves. These results provide new information toward understanding relatively low levels of herbivory on individual willow leaves associated with the feeding ofP. versicolora.
