Scientists are waging a war against a pesky pest targeting avocado trees before it reaches California.

The beetle is threatening trees in several states where it has killed 90-percent of infected trees. Scientists are concerned the beetle will soon reach California, which is a major avocado production state.

Researchers are working to minimize the threat. Right now they're developing new fungicides to slow the spread of the disease.
