Thrips Damaging Onion Leaves

On November 19, Joe Cruz brought in some onion leaves with apparent thrips damage. Managed to find one thrips but it did not look like the usual suspects.

I have tentatively identified it as Dinuthrips hookeri based on a match to the description and images on the Thrips of California web site.

This thrips was first detected on Guam early in 2012. This is a South American species which has spread to the Caribbean and Florida. To date, it has not been found in California or Hawaii.

More info to be posted here in the near future.
