Ribes nigrum, Denmark © Simon Haarder: opened gall with mites

gall

in April-May infected buds may contain thousands of mites. A part disperses and infects new buds, that around Augsust attain their maximal size, then die and fall off.

hostplants

Grossulariaceae, narrowly monophagous

Ribes nigrum.

synonyms

Cecidophyes ribis; Phytoptus, Eriophyes, ribis Nalepa, 1893.

predators

Aprostocetus eriophyes.

notes

the mites are noxious not only because they cause the death of many buds, but also by transmitting a virus, viz. “black currant reversion disease”.
