Effects of zucchini yellow mosaic virus on colonization and feeding behavior of Aphis gossypii (Homoptera: Aphididae) alatae
Environmental Entomology 21 (3), 578-585
Abstract: Cucurbita pepo L. (zucchini) plants infected with zucchini yellow 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.
