Symptoms

Adults and larvae both feed on the surface of leaves, scraping away the surface cells between the main veins to leave irregularly shaped holes or strips. Heavy feeding damage will skeletonize the leaf or leave it with a lace-like pattern.

Prevention and control

Chemical Control

Due to the variable regulations around (de-)registration of pesticides, we are for the moment not including any specific chemical control recommendations. For further information, we recommend you visit the following resources:

• EU pesticides database (http://ec.europa.eu/food/plant/pesticides/eu-pesticides-database/)
• PAN pesticide database (www.pesticideinfo.org)
• Your national pesticide guide

Impact

H. pusillanima has been recorded as a general pest throughout its range, but specific past examples are difficult to assess because of misidentifications.
