I guess I'll always wonder how much of funding to Darian Gap and Metalpa in Mexico facilities went to the project and how much was diverted to The Big Man or others, instead of funding the project?

Just think about this- if they even would have used just 2 % of all the fraud money in Minnesota and California - the screw worm would have probably been killed 1000 times all the way down to Brazil - maybe even pushed it into the Atlantic ocean

coulda woulda shoulda.

The Texas cattle industry will be devastated. And everyone knew it was coming and they didn't act.

This is what government failure looks like. This is what the tragedy of the commons looks like.

Cattle will not be devastated. I've not heard of a single death yet. There will be some but I think many cases will be discovered and treated. It is a huge PIA to deal with.
Wildlife on the other hand is a concern.

Pretty good informational meeting last night in Johnson City, put on by the Extension Service. Primary speakers were Dr Sonia Swiger (Extension entomologist from Stephenville), Dr Dustin Dorris (TAHC vet), a couple of local vets, and a director from TPWD. Probably 100+ attendees. Two bits of information came out that were of particular interest to me.

1) NWS fly activity becomes dormant below 59 degrees -- I'd always wondered what the threshold was, and that's it. The absolute optimum temp that maximizes NWS activity is mid-high 80's, so...ugh.
2) Efficacy of fly tubs etc in being beneficial is relatively low. Any mode of action that treats manure for fly control won't really impact NWS, as manure doesn't figure in to their life cycle (that's what the living tissue feeding does for NWS and is what makes them unique). General fly control through Permethrin etc was really being pushed as a good control/prevention measure (not 100% effective, but it'll help).

One other thing that caught my attention was that the metric they're pushing to for sterile fly production is 500m / week production is what's needed to re-eradicate NWS. Right now we're at about 130m / week. The Edinburg facility adds 300m / week when it comes online in Fall 2027.

Makes me nervous that there is so much riding on the Edinburg facility. They seem to be placing all their bets on that. I hope and pray that they don't hit delays or sabotage on that facility, because I sure haven't been able to see any viable backup plan that's being executed from a fly production standpoint. (Not to say there isn't one, I just haven't heard of one.)

I had seen that information on temps and it further confuses me. Why is the fly so prevalent in north Mx and South Texas if they like 80's? It was clearly about 140 last weekend down there. OK, seriously with temps in high 90's to low 100's it seems that it would slow things. Maybe it does.
Wish I had known about that meeting, I was through there at about 5:30 .

High 80's are still happening down there, at night, so even when we're at our hottest, we'll still have high 80's windows. They gave a max temp as well but I don't remember what it was (honestly wasn't as concerned with that one).

Keep an eye on your local extension service calendar -- I think they are the ones putting these meetings together. You're in Burnet County, right? I'd give them a call as my impression was that the Ag agents at least in our area are being told to organize these local informational meetings. I think Llano had a meeting like this a few days ago, with some of the same speakers and info.

Seriouslee, none.

One question to ask is what impact screwworm has had on Mexican cattle industry, and does that portend what will happen to the US cattle industry?

It seems like much of the Mexican cattle industry relied on selling calves and cattle to the US (live animals). That's ended. So they've taken huge losses from that. As they have had to sell only domestically. Which has led to them trying to export beef instead. But it takes a long time for that to ramp up. So we are going to see some fundamentally changed economics from screwworm related to how the industry is changing in Mexico. They will build up their own industry internally and rely on exported beef.

It seems the main impact in the US is related to the huge increase in manpower needed to check and treat cattle, and then the costs related to inspections, difficulty in making sales of live animals out of quarantine. Lots of increased inputs.

Yea I'm in Burnet/Llano counties at home. Cattle are in Zapata. They are having a meeting down there on Thursday but I just got home after a week there. Not sure what I'll do. Going to take that inspector course online today and see what light that sheds. I also attend the Thursday from 1-2 pm webinar call thing with TSCRA. They have been very informative.
Thanks

I agree, my dad fought it in the 70s and 80s, maybe early 90s, i don't think he said it really did too much damage. It will Probably cost us a little more for a steak to get rid of those flys though. It will be more of a Pain in the arse for the ranchers to keep an eye on their cattle and then treat them when they find infected cattle and/or deal with the quarantine stuff

Where in the 70s and 80s? It was gone by then in the US

Possibly before that or early 70s… I just remember our dad telling us about it, I don't remember when he said they dealt with it. I thought he said ir was the 70s..

It was, I spent a lot of time in 72 checking newborns that summer, we turned in a bunch of samples to try to get our area targeted for fly releases. Rumor was that the outbreak, after a several year period of no cases, was due to workers at the production facility not irradiating flies after they didn't get a requested pay raise.
Deerdude
How long do you want to ignore this user?
Yea they officially call the outbreak over by mid 60's I guess, but we still had flies being dropped in early 70's.
You get a sample and put inside a cardboard cylinder with metal screw lid, self addressed to USDA somewhere. Run into town and drop off at post office. Several days or a week later you got a letter back with results. If it was positive they instructed you to go out and mark the location with a sack of lime. Make a big X on ground. At some point a little Cessna 182 I think it was flew over and bombed that X with a box of flies.

I took that fly inspector course yesterday. It cleared up a few things for me. At the end they ask if you want to be made official and I figured sure, I'm kind of retired and don't mind helping out. After the secondary exam they listed several entities and ask which I work for. None of the above was not even an option.
Do I guess they don't need inspectors that bad after all.

When we moved to the Valley in the early 80's, around 82', and for years after that you would see all the signs along the roads and such. My memory fades nowadays but I want to say that the place making the sterile fly's in Mission, it was at the old Moore Field airbase, was in operation until the mid-80's when it was all transitioned to Mexico. There were news stories and articles and I wanna say someone I grew up with had a dad involved in it.

As a kid my parents would drive back and forth from CDMX to Houston, and other parts, at least 2 to 3 times a year. On those trips there were always several agriculture checkpoints on the Mexican highways, I remember those. We usually traveled with dogs and if the check point saw the dogs in the car they would pull you over and inspect. Surprisingly enough crossing the border with dogs in the 1970's, and according to my parents in the 60's as well, was a much more formal deal, it was nothing in the 80's through the 20's. I now believe it was due to the screw worm, but I was too young to know.

There were strict quarantine areas and controls in Mexico for years (that lots of folks circumented I am sure). In the late 80's and through the 90's when I was spending a lot of time roaming around Northern Mex, and doing as much hunting and fishing as possible, I know ranchers would occasionally run into screw worm issues but they were very secretive about it as they had no faith in the MexGov to help them with it.

Where I lived in Central America it was around, and never went away completely, but it was not treated with the dire alarm that we are seeing in the U.S.. Why? I have no idea. I am not an ag man at all, so all of this is just purely observation from an unknowing point of view.

Moore Field has been a hub of fly production for decades. It was the original US screwworm production facility and when that moved to Mex the Mexican Fruit Fly production ramped up. I think that effort has been in constant operation since the 80s. Now it's getting into the fight again with a new screwworm facility.

In the quarantined areas now, all transported warm-blooded animals are required to be inspected before they can leave the area. That includes pets (e.g. dogs).

Can you move animals within the quarantine zone without inspection, or can't leave your premises without inspection?

I am not concerned at all about this, but this may be the place (as always) to settle this with my wife. She is concerned that we are taking our Pyrenees and Aussie to Concan next week to hang out on the river. We will be there 4 days. She is determined that the dogs have to be inspected before we can leave the county. I don't believe that to be the case in that they are not living in the county. (Unless they have a lesion or cut)

What say you TexAgs? If we have to get them inspected on the way back, we will do it, but if not, I contend that is so low risk that it is almost comical.

So I talked to my brother about this, he told me that they were still dropping boxes of sterile flys on our property in South Texas well into the early 80s, maybe even late 80s. He said dad would find the boxes in the hay fields each year when baling hay. They may have continued the program long after the problem was solved out an abundance of caution to make sure the flys were gone. I don't know when the last infection on our land incurred?

I know this is picky but you keep calling Dectomax a vaccine and it isn't. It is a parasiticide that will kill the larvae for up to 21 days. It does not induce an immune response or provide any long term protection. A vaccine against screwworm would be a total game changer.
Deerdude
How long do you want to ignore this user?
What they telling us in inspector course is that Ivermectin is a preventative, and Dectomax is both a preventative and a treatment for infestation of an animal. I'm not mislabeling it, they are. They being both USDA and TAHC. If my statements are incorrect I apologize for repeating what the agencies tasked with eliminating this bug are saying. I've spoken with field hands at length from both agencies.
FishrCoAg
How long do you want to ignore this user?

I took the course as well. They never called it a vaccine. It is preventative in that it kills the larvae before they can inflict damage and prevents them from developing. Vaccines induce an immune response in the host to prevent disease.

End of derail.

Concan is not in the infected zone- just the surveillance zone. No inspection is required unless leaving the infected zone.

It's only good as long as there are active drug levels in tissue as opposed to vaccines which induce an immune response that lasts longer plus enables the animal to mount an immune response to exposures further down the road, from as little as a few months to years for some vaccines. Long after the vaccine itself is gone. Smallpox, MMR, etc.

If an employee of the Texas Animal Health Commission is calling Dectomax a vaccine, they need better training. I've worked with a lot of them over the years and they all knew better. I'm sorry, but some words have objective meaning. Injection =/= vaccination.
