Capsid bug (last updated 08 July 2008 )

Sometimes called Mirids, up to 6mm long, very active insects (hemiptera miridae) winged, membrane type legs and long antennae and proboscis. The nymphs are similar but without wings. Their colours are yellow, green and brown depending on species. Adults & nymphs pierce plant tissue with their fine stylets, inject saliva and suck sap. Their saliva kills plant tissue; some species also feed on mites, aphids and small caterpillars so they have some beneficial effect. 

The main species are:- Common Green Capsid (Lygocoris pabulinus) Potato Capsid (Colocoris novegicus) Aplle Capsid (Plesiocoris rugicollis) Tarnished Plant Bug (Lygus rugicollis).

Impact/effects on chrysanthemums
Young leaves often have small ragged holes followed by tattering. Buds and shoots may be killed and flowers often develop with malformation. They are difficult to detect because they are quick movers and they often drop off a plant and fly away. The worse time for capsid attack is late spring/early summer. They attack very many garden plants.

They are often confused by gardeners with Frog Hopper (Philaenus spumarius) which are known as cuckoo spit. However Frog hopper damage is different. They pierce the young stems and often cause cocked heads or buds. 

Treatment for both is best by spraying with a systemic insecticide such as Imidacloprid.
