Vignettes on Summer Insects

Russell F. Mizell, III, Professor of Entomology, NFREC-Quincy

Planthoppers

Mid-summer is upon us and the usual calls and emails are coming in with “What’s this bug?” Usually it is a flatid planthopper (pale green adult picture) and most of the time it is Metcalfa pruinosa. These are native insects that feed on plant sap and do very little damage. The nymphs (white fuzzy object on plant) are often gregarious or at least clumped on stems where they cover themselves and the stems for protection with copious supplies of a waxy, stringy white substance. They also sport waxy setae that form a tail-like structure. When they are disturbed they jump from the plant to escape.

Citrus psyllids

Everyone in the state should now be aware of the dire disease – citrus greening- threatening citrus production in the U.S and around the world. The causal agent of greening is a bacteria that is spread (vectored) by the Asian citrus psyllid. The psyllid is a small insect ~3-4mm long and gray in color. Producers of satsumas in north Florida are concerned about whether the psyllid or the bacteria is present. The psyllid is a tropical insect and is unable to survive colder temperatures. To date, based on trapping completed since early spring in Gainesville, Live Oak, Quincy and Jackson County, there are no known infestations of citrus psyllids north of Gainesville. Moreover, citrus psyllids from Gainesville that have been genetically analyzed for the greening bacteria have all been negative. Given that no citrus psyllids have been trapped or observed by this time of year, it is unlikely that active infestations exist. That means that producers and homeowners should be very careful to only purchase new plants that have been grown under the state regulatory quarantine procedures. If citrus psyllids do show up later this year, their source will likely be traced to a person bringing them in with new plants, as opposed to either immigration from Central Florida or a resident population.

Bermudagrass stem maggot

Populations of this invasive grass-infesting fly have been on the rise around the Suwannee Valley area and south but have yet to show up in high populations further north. This is based on field sampling this week in Jackson and surrounding counties. We expect that they should be detected any day now, so stay alert to the problem. However, army worms are a different story and are widely apparent in high populations around North Florida hay fields and pastures.

Hi--my name is Pat Watkins and I am a master gardener in Columbia County, FL. I am trying to put together field trips for my group and wonder where I can find info about the Gardens of the Big Bend. If field trips/group tours are not available, then I am personally interested in the Magnolia Gardens. Where can I find out about that, please?

Dear Joe: I work with tomato in Brazil, west part of S.Paulo State, and so far TSWV in one of most important virus disease in my area. This article is very important, because I can now be more confident that there is a new strain (TSCV) of tospovirus also occurring in my field. Hopefully TSWV tolerant hybrid tomato could be also be tolerant to this new strain TSCV. Vanderlei Barbosa (Agronomist, tomato grower)

It is a relatively new byproduct but our first estimates based on digestibility and nutrient analyses indicate that the TDN of B. carinata meal should be around 70-75% TDN.

Thanks for your comment! The Black Diamond series of crapemyrtles have been planted at the UF North Florida Research and Education Center (outside Tallahassee). An older, outstanding planting can be found at the Louisiana State University Hammond Research Center, if you happen to be traveling along I-10 in Louisiana.

I found this article most timely as I just purchased my first crape myrtle ever. It is the black diamond series with red blooms. I can't wait to see how well this performs here. I hope eventually to plant it in my yard also at my home in Brevard county(Melbourne) also. Are there any evaluations ongoing for this new black diamond? It's the first crape myrtle ever that I liked well enough to plant. Thanks!!!!!

Hi Gary, I was just reading the crapemyrtle article and then looked at the bottom to see it was by Gary Knox. Marilyn (Bennett) Akers and I live in Elberta, AL (near Pensacola) six months a year. We've planted several crapemyrtle at our home there. I retired from Purdue Extension 2 summers ago. In case you don't remember, Marilyn was Phil Carpenter's grad student. She say hi! I got a Master's in Botany & Plant Pathology. I was Purdue Extension Educator, Ag & Natural Resources for 30 years. All in Boone County, (Lebanon) less than an hour from W. Lafayette. We still have our home in Lebanon, too. Doug Akers

Excellent, and to the well trained ear, this article may well be the best introduction to profitable grazing for all ranchers, and not just for cattlemen. "Adjusting the stocking rate...is the most important grazing management tool to improve forage utilization." Well said, but rotational grazing only marginally adjusts the stocking rate and still allows the animals to pick and choose what they eat, taking the best and leaving the worst--thereby affirming that animals don't make good business decisions. Adjusting the stocking density (not rate) using management intensive grazing whereby one restricts the amount of available forage insures the animals consume only an amount of forage required to meet their demands for the day and are then released the next day into a new paddock (subunit). The amount of acreage provided daily can easily be estimated while considering all the factors listed above. The key is inexpensive temporary electric fencing and a good eye for growth rate. For those willing to follow the successful and disregard the "That won't fly around here Sonny"-mentality, I'd point you to "Management-Intensive Grazing: The Grassroots of Grass Farming" by Jim Gerrish; or visit http://www.americangrazinglands.com/

Other than cutting my hay field, what can be done when army worms are found ? Is there any preventive measure that can be taken to help prevent army worms ? Will adding sulfur to my fertilizer help prevent army worms ? If so how many pounds to the acre ? What can be sprayed to kill army worms ?

Is there any Balansa Clover seed available for sale to the public? I would love to try some on my farm. Hope I can get over and see all the projects you all have going on. Tim Tucker Uriah AL.

I adore pomegranate fruit and shrubs, so I was especially thrilled to learn of this new variety. However, I’m not sure how I feel about one that doesn't produce edible fruit . I've had a pomegranate in my greenhouse for several years, and although it doesn't produce much fruit, it’s always a beautiful, flowering plant. I’d recommend them to anyone. As to fruit, I think the Wonderful variety (as its name implies), is simply wonderful and the most delicious variety I've tried. Richard

Hello Peter, My wife and I are new at planting trees. We have 20 acres in North Walton County and the pH is 5.7. Please correct me if I am wrong, but it looks like the fuyu species is the best all-around fruit. We are looking at planting 5-10 trees. In addition to applying fertilizer as you discussed, should we address the pH level as well? Can we obtain the trees through the extension office? If not, can you recommend a source where they are available? We are open to any suggestions you may have. Thank you in advance for your help- Brett

The sort of trimming known as "crape murder" will not ensure the long term health of the crapemyrtle. Those repetitive cuts will allow disease and rot to enter the tree. Older cultivars might be in too much shade and not blooming to their full potential. They may also be suffering from powdery mildew, scale or sooty mold. Thinning of the interior of the tree may help. See this publication on crapemyrtle pruning for more information.

I love crepe myrtles of any kind. I guess it reminiscent of my grandmother's gardens. In southwest Florida she never cut back our crepe myrtles and they were more like the last photo in bloom. However, here in the Panhandle everyone does what I my sister and I call crepe murder, cutting the trees back. I want to know what is really appropriate. I've always said this was improper, but I notice that the trees that are cut this way to appear more healthy and vibrant each spring. I've moved to a home that has several varieties and the older ones are not doing well (blooming profusely) but I'm afraid it's because I have refused to cut the trees, I just trimmed them a little. Thanks for your help.

Dr. Anderson was talking about the gradual cooling that occurs normally in Northwest Florida. More damage occurs with extreme temperature changes, like can often happen in South Florida.

What is meant by cold pre-conditioned trees in your article above? Is that something that nature does, or something that the grower can do?
