Eradication Strawberry Guava (leaf gall)
#11

Hello Everyone,

Your concerns for the release of a biological organism to fight strawberry guava are the same concerns researchers had decades ago. Because of those concerns, laws have been put into place that protect us from serious oops's!

The mongoose is a bad example because it was not done with any sort of research at all. It was not done by government, instead, it was done by sugar farmers or ranchers from foreign lands who "thought it would be a good idea". NO research involved.

That was "yester-year", over a hundred years ago. I think we should give our federal and state departments of agriculture a little more credit and a lot of thanks, for the many years of careful, quarantined research that has gone on, in order to make this possible.

Biological controls don't normally kill its host. So for anyone who's afraid of waiawi disappearing, please don't fret. THAT WOULD TAKE A MIRACLE, not a magic wand or a biocontrol. Waiawi won't disappear, but if its numbers are reduced significantly, then the native forest will have a chance to survive.

For example, a biological control for MICONIA was released about eight or ten years ago. It hasn't become a problem, and it hasn't killed all the Miconia. But it's killin' some!

Dear Department of Agriculture,

Thank you for allowing the cocqui to take over this island recently.

Damon

Ms. Tavares,

Asking me to believe anything the government tells me will almost automatically send out a red flag to me. [Wink]

Please explain the Cocqui frog to me [Wink]

A little further reading here led me to the scientific name of this bug they want to release:

Tectococcus Ovatus

In this Report if you read the conclusion of the testing that was done in Brazil, it states:

In the absence of its natural enemies Tectococcus ovatus may be very effective as a biological control agent because heavy infestations result in premature leaf drop. In some instances, complete defoliation of the tree has been observed.....This agent, however, will be not able to control strawberry
guava alone
because it is most effective only at high elevations of the host plant's range. This is a particularly attractive Characteristic for Hawaiian forest managers because the remnants of native forest are essentially confined to upper elevations.


So what about all the *edit* native forests found at the lower elevations? How do we use these bugs in Lower elevations?

There are no "native" forest at low elevations because trees like guava have pushed them out following massive clearing and and host of other invasive species. Controlling strawberry guava is critical to helping reforest some of those areas. Without using biocontrols many invasive plants would cost millions and millions of dollars to eradicate particularly strawberry guava because its spread by birds, pigs, cows and goats. If any of you would like to see "native" lowland forests in Hawaii in our lifetime this biocontrol will certainly help.

We just bought a lowland lot with no albesia mostly Ohia, and I intend to keep em out!
Nothing is going to smother albesia!

I have no problem with controlling and eradicating the Strawberry Guava, McNaughty...

I just wish they could find a more proven way that they can "GUARANTEE" won't harm Hawaii down the line.

Damon, here we go with experts it was only yesterday we heard the thing only affects upper forests, now it's down to the sea! Most testing has been in Brasil!
I like the EPA control method, you can be hauled back for damages even after retirment! Personal Fines!

And other departments or agencies related to the draft environmental assessment

Subject: Supporting the Release of Tectococcus ovatus for classical biological control of
Psidium cattleianum Sabine on forested state lands.

I read the draft environmental assessment and I offer the following comments:

I live in a subdivided forest area within five miles of Ola`a forest. It has been my full-time residence for over thirteen years. This subdivision and the neighboring subdivisions are forested lots zoned for agriculture by the state and county governments, and surrounded by State forest lands (NAR and forest reserve). Even within the subdivision the forest is predominantly native species, however a number of invasive species also persist. Strawberry guava is at the top of the list of most aggressive pests in this area. A slow drive along North or South Glenwood road will make this obvious. I am looking forward to this organism’s natural spread across the highway and into my neighborhood.

• The level of detail in the draft assessment is enough information to make a sound decision on whether or not the organism is safe.

• The host specificity test results were impressive and acceptable.

• I am impressed that the planned release is strictly contingent upon six or more government permit approvals and various other requirements.

Many residents in this district have fruit and vegetable farms on their property, and farmers constantly battle fruit flies. I myself have trouble keeping them away from my fruits and vegetables. I understand that the reduction of healthy strawberry guava on public lands will eventually mean less work and expenses battling fruit flies on the farm, and I applaud the effort. Many people use the plant for food, firewood, cooking fires, and as construction material because it is a plentiful hardwood, and I don’t expect T. ovatus to have any more impact on strawberry guava than land clearing and development. If it should be that successful, alternative species do exist for domestic needs. A biological solution to preserve native species habitat, that involves nothing toxic, and reduces an agricultural pest, is beneficial.

Since it’s not likely the bio-control agent would destroy all individual plants within this species, I am confident that fears expressed by a few individuals are unfounded, and that all the concerns that are aired, have been researched to a satisfactory level, with good results. I believe the opposing comments are from people who have very honest fears, but have not read the document or don’t trust science or government simply because they are not well informed. Strawberry guava is a useful plant out of place, and does not belong in the Hawaiian forest. It is aggressive, dominates the sunlit spaces of any open area, and is considered a pest by all but a few.

I strongly urge you to permit the release of Tectococcus ovatus onto State of Hawaii lands, with the assistance of State of Hawaii employees and funds.

Sincerely,
Kim Tavares

So Ms. Tavares,

Your willing to risk the islands on speculation?

Didn't the Farmers speculate that mongoose would control rats?

Apples/Oranges...etc...

I understand government funding.... and I'm curious as to what your vested interest in this is?

I want a guarantee that these bugs that the government is saying is going to help...will actually help and not harm.

Who can guarantee this?

Everything is speculative.

THERE MUST BE ANOTHER ALTERNATIVE!

To Damon,

I am not sure if you really want answers to your questions. If you are open to reason, I'm willing to talk, but if your mind is already made up, then I can not help you.

Respectfully,
Kim

PS: I have no vested interest other than what was stated in my official comment. I know a little about it because I have educated myself about the subject, and made it my life's work to control invasive species.

You mentioned Coqui frogs earlier, I control them too. Sure, it's after the fact, but why do you assume HDOA is to blame? We don't pay enough taxes for our government to be pro-active, just reactive.

I want all waiawi in Hawaii to wither and die because the alternative is that it that it will eventually be the dominant forest tree, replacing ohia as the old ones die. It does not allow new ohia (or anything else) to grow in the same space. Strawberry guava is worse than Miconia, and it's going to win, unless we use every SAFE (by stringent test standards), tool available.

I know waiawi up front and personal. Have you ever had to try to catch a Coqui, while climbing on a thick spaghetti matte of strawberry guava trees ... in the rain ... and suddenly finding out that you're ten feet or more above the ground and about to eat dirt or sprain a leg?

There is no magic bullet to make all the waiawi disappear overnight, or even over a period of decades. If someone said there were I WOULDN'T trust it. This little scale is meant to be more or less benign, very specific to strawberry guava. As far as insect evolution goes, it's common knowledge, every crop has it's own pests. Ask any farmer. It's likely nobody will even notice it for at least another decade. (who even pays attention to trees anymore?) If it eats all of it's host, it will likely die out. I know that word is a red flag to you, but research exists to back up the claim, and it looks really very good. Please read the info in the appendix.

I'm not hiding the fact that I know some of the scientists involved, and so I knew the research was going on before it was done. It's a small advantage of staying in the loop, the info is out there to be found, if one looks. (try HEAR.ORG for starters)

Another message metioned albizia ... "why isn't anyone doing anything about that?" Again, uninformed. People are doing something about that too.
