The Solomon Islands biosecurity department is deploying teams around the country to try and contain the spread of the coconut rhinoceros beetle.
The division's director, Francis Tsatsia, says sightings of the beetle have been reported across the country.
The beetle bores into the crown of the palm tree to feed on the sap, which can devastate palm trees - a major part of the economy.
Mr Tsatsia says teams have been deployed to Tulagi, Choiseul, the Shortland Islands and Savo to verify the reports.
He says if the pests are found, the teams will focus on trying to contain the beetles.
