Aphids on Lonicera Hispadula

Asked April 20, 2018, 7:21 PM EDT

My vine is not produced flowers. It appears that aphids are on where the flowers should be. What can I do to get flowers?

Honeysuckle vines are often attacked by aphids as new growth begins. As it turns out, these aphids (Hyadaphis tataricae) are specific to honeysuckle.

These aphids survive the winter as eggs which were laid near the tips of the vines the previous year. The first of several generations will hatch as new growth begins. As you can see, feeding can distort the new growth, both leaves and flower buds. (Flower buds are in your first picture, but they will be permanently distorted if the aphids remain on them.)

Fortunately, aphids are easy to manage. When only a few are present, you can wipe them off. But when they’re as numerous as they are now, a harsh water spray efficiently knocks them off the plant. Repeat every several days, as needed. (Apply early in the day to allow drying as soon as possible.)
