g - How is the geographical distribution of pests & diseases changing? Which new biotic threats are awaiting NWFP?

Among essential oils, Eucalyptus oil, is one of the most useful as it is easily extractable commercially (industrial value) and possesses a wide range of desirable properties worth exploiting for pest management. Eucalyptus oils are mainly extracted from leaves which can be attacked by gall wasps as Ophelimus maskelli. Induced galls can affect the essential oil production.

This work aims to determine the role of the parasitoid Closterocerus chamaeleon in the biological control of its host O. maskelli.
