Medfly for California in April - Ceratitis capitata - male

Medfly for California in April - Ceratitis capitata - Male
Santiago Oaks Park, Orange, Orange County, California, USA
April 14, 2007
On an orange peel in an old grove, established circa 1935.

Needs to be reported
If this really is a Mediterranean Fruit Fly (it looks like one- but what do I know?), either the county or state agricultural authorities should be informed about this ASAP. If it's a new, unreported infestation this could be very, very serious.

I sent an email to the address given on the California Dept of Food and Agriculture website as the one for "fruit fly quarantines", but I'm not sure if the contact list is up to date or if anyone monitors that address with any regularity.

This page lists three different Orange County offices of the state Plant Health and Pest Prevention Services.

Perhaps Peter Bryant knows whom to contact, if not the above.

 
This is the third one I've found and my second post.
Like you, I thought the state wanted to know. As far as I can tell, they've lost interest and are in hot pursuit of the Oriental Fruit Fly instead. There is no online mechanism I could find for reporting Medflies. I called a toll-free number based on info I found at a state website, and there was no option to report medflies. At that point, I gave up. Peter had no suggestions for reporting.

A theory I've heard advanced is that there are tons of sterile medflies sponsored by the state, so nobody wants to hear about them. Both my posts were male.

Once you've seen one of these flies, you know it immediately. They have an odd posture when viewed from above - not very fly-like at all. (See my earlier post for the posture.) I checked for photos of females and found they have a long, pointed ovipositor and are quite different from the males in appearance.

I appreciate your concern, but will not try a second time to report the critter's presence. But feel free to do what you want with my info.

Ironically, this particular fly was in back of the office of a county regional park. The office was closed when I was there.

 
Point taken
I didn't notice your other images. By the way, the sterile males are supposed to be identifiable by looking at them under blacklight: the larvae were marked with a dye that glows in UV light, and some of it remains in the adult stage.

 
It's good you're concerned.
There used to be tons of fly traps in Orange County; now they're few. Guess that says something. I had heard that about blacklight. Maybe next time I'll effect a capture and shine that fly on!

The big deal down here now is dead birds. Tell the county vector control people about one, and poof! it's gone. There are also a couple of quarantine stations where I hike - small chicken-wire enclosures with several convict birds in each.

 
Info
Having recently transfered into San Diego's Pest Detection Program, I can say it is still considered one of the concerning pests. However, sterile males are constantly released year round in the LA basin area. Sometimes, a little dye is visible to the naked eye (generally around the frons) but it is difficult to detect. I would say that this one is no cause for alarm, as LA is under constant treatment (they had so many introductions, that was cheaper than surveillance).

 
Thanks, Austin, for the update.
