西葫芦感染小西葫芦叶花叶病毒（ZYMV）4周的小西葫芦植株在田间被棉蚜（Aphis gossypii格洛弗）拒绝为定殖宿主，其拒绝率高于未感染的小西葫芦和感染2周的植株。利用电子摄食监测仪对A.研究发现，与感染4周的植物相比，未感染的西葫芦和感染2周的植物上的探测事件较少，韧皮部接触较多，并且产生的粘液较多。当韧皮部接触的植物感染4周，alcohol花更多的时间在唾液鞘的形成和更少的时间韧皮部喂养比alcohol未感染的植物，植物感染2周。这些定殖和取食反应可以增强ZYMV从西葫芦中的获得。
Cucurbita pepo L. (zucchini) plants infected with zucchini ye ow mosaic virus (ZYMV) for 4 wk were rejected as colonization hosts by Aphis gossypii Glover (melon aphid) alatae in the field at a greater rate than uninfected zucchini and plants infected for 2 wk. Using an electronic feeding monitor to examine the feeding behavior of A. gossypii on plants treated similarly, the study found fewer probing events, more phloem contacts, and more nymphs produced on uninfected zucchini and plants infected for 2 wk, than on plants infected for 4 wk. When phloem contact was made on plants infected for 4 wk, alatae spent more time in salivary sheath formation and less time phloem feeding than alatae on uninfected plants, and plants infected for 2 wk. These colonization and feeding responses could enhance ZYMV acquisition from zucchini.
