The anti-feeding activity of the ethanol extracts from Pinellia ternata Breit against Henosepilachna vigintioctopunctata(Fabricius)was studied in the laboratory.

This invasive species has caused significant damage in other countries through nesting and feeding activity and we are taking action now to prevent this happening in the UK.

Scientists marked orexin cells in mice brains so they would fluoresce. Then they tracked the cells' activity after feeding the mice different kinds of food.
