PEST
 
   NAME
     Metallic Flea Beetle
     Alica species
 
   ORDER
     Coleoptera
 
   FAMILY
     Chrysomelidae

Description of the Pest
Adults are small (up to 3mm long), with shiny metallic bodies, long antenna and thick, jumping hind legs (hence the description as a “flea beetle”).

Appearance and Distribution of the Pest
Larvae appear from Summer through Autumn primarily on the east coast of Australia.

Life Cycle
These insects have a Holometabolous life cycle, ie. When metamorphosis is observed during the pupal stage.

Period of Activity
During the warmer months of the year.

Damage Caused
Larvae emerge in the stems of the plants. Shoot tips and the upper surfaces of leaves are holed by feeding adults and, as the leaves mature, the holes become enlarged, giving the plant a damaged appearance. Young plants and seedlings may be killed during heavy infestations.

Susceptible Plants
Many plants are susceptible, including hibiscus, dahlias, grapevines, avocados, potatoes, sweet potatoes, rhubarb, and various weed species.

Cultural Control
Sticky traps may be used. 

Biological Control
None known.

Chemical Control
Spray with a contact chemical such as Carbaryl during infestations.
Note
Always read the label for registration details and direction of use prior to application of any chemicals.
