Many Florida citrus growers in recent years have used individual protective covers (IPCs), often referred to as “bags,” for pest management, especially to protect young trees from HLB-spreading Asian citrus psyllids. Lauren Diepenbrock addressed the benefits and challenges of IPCs at this year’s virtual Citrus Expo. Diepenbrock is an assistant professor of entomology at the University of Florida Institute of …
By Larry Duncan, Johan Desaeger and Sheng-Yen Wu The citrus row middle habitat changed profoundly beginning in the 1970s as mowing replaced disking for weed management. This change ended the costly cycle of cutting and regrowing citrus roots near the soil surface and reduced soil erosion, among other benefits. Mowing also allowed a seasonal succession of native plants to flourish, …
The U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS) and the Texas Department of Agriculture (TDA) in late July removed the Mexican fruit fly (Mexfly) quarantine area in Lasara, Texas. Lasara is in Willacy County. The quarantine in Lasara had been established in January. The agencies had restricted interstate movement of regulated articles from the area to …
A snail causing problems in Highlands County and South Florida groves “appears to be popping up all over the state,” said entomologist Lauren Diepenbrock. The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researcher identified the snails as Bulimulus sporadicus. “It was first documented in Florida in 2009,” Diepenbrock said. “Citrus is not the only crop to be …
The U.S. Department of Agriculture Animal and Plant Health Inspection Service (APHIS) recently released an annual report titled “Plant Protection and Quarantine: Helping U.S. Agriculture Thrive — Across the Country and Around the World.” The document includes updates on efforts to manage citrus diseases. “PPQ (Plant Protection and Quarantine) stands shoulder-to-shoulder with citrus growers to combat citrus canker, huanglongbing (HLB …
An update on lebbeck mealybug, a relatively new pest of Florida citrus, was provided recently by University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) entomologist Lauren Diepenbrock. Diepenbrock, who works at the Citrus Research and Education Center, prepared the presentation for the April Florida Citrus Growers Institute, which was canceled due to COVID-19. Lebbeck mealybug was found in …
The Animal and Plant Health Inspection Service (APHIS) and the Texas Department of Agriculture (TDA) established a Mexican fruit fly (Anastrepha ludens or Mexfly) quarantine in a residential area in Zapata, Texas. APHIS is applying safeguarding measures and restrictions on the interstate movement or entry into foreign trade of regulated articles from this area. APHIS confirmed one Mexfly larva from …
The Asian giant hornet (Vespa mandarinia), typically 1.5 to 2 inches long and a threat to honey bee colonies, has been found in Washington state. Amy Vu and Jamie Ellis with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Honey Bee Research and Extension Laboratory recently provided information about the pest. “This insect has recently been called …
Italian citrus grower Giovanni Battista Spanò will combat the citrus nematode, Tylenchulus semipenetrans, with natural methods involving sowing and green manure of the radish cultivar Defender. The nematodes cause slow decline of citrus. “Nematodes and fungal diseases of the soil are a problem that can be easily solved without using harmful chemical products,” says Spanò. “We can just exploit the …
By Clint Thompson April is Invasive Plant Pest and Disease Awareness Month, and the United States Department of Agriculture (USDA) wants help in identifying invasive species that threaten the food supply and cause plant diseases. Samantha Simon, USDA’s executive director of emergency and domestic programs, says invasive species can threaten agriculture and many farming operations, especially in the Southeast. She …
Incentive-based policies have had success in some industries by helping regulate air quality, control pollution and protect wildlife and fisheries. But two University of Maryland professors in agriculture and resource economics have determined that incentive-based tariffs likely aren’t the answer to controlling invasive pests in imported fruits and vegetables. Erik Lichtenberg and Lars Olson published their findings recently in the …
Researchers from the University of California (UC) Cooperative Extension and UC Davis are beginning a two-year study to develop an effective management program for removing roof rats from orchards. The researchers are looking for growers who will allow the UC to work in their orchards to test methods for monitoring roof rat activity. Roof rats can run rampant and cause …
Citrus under protective screen (CUPS) and young trees covered with individual protective covers (IPCs) have generally been well protected from HLB-spreading Asian citrus psyllids, but not from all other pests. Entomologist Jawwad Qureshi says the psyllids only get to trees when a CUPS structure or IPC is damaged, as happened to CUPS during Hurricane Irma in 2017. “Otherwise they do …
The mission of the California Department of Food and Agriculture (CDFA) is to promote and protect the food supply, enhance trade and protect the environment. The agency annually provides information on the steps it takes to fulfill its mission goals. In such a diverse and highly populated state, the challenges are great. Much of the growing regions are geographic islands …
One of Lauren Diepenbrock’s props at a Jan. 14 OJ break at the Citrus Research and Education Center was a paper plate bearing the message “Easy diagnostic: smashed lebbeck mealybug = purple guts.” Diepenbrock, a University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) entomologist, explains the meaning of the plate’s message. UF/IFAS researcher Lance Osborne found a lebbeck …
By Lauren Diepenbrock Non-psyllid, soft-bodied insects are common in Florida citrus. Their ability to cause damage varies by pest, pest population size, tree age and tree variety. Soft-bodied insects include scales, mealybugs, whiteflies and aphids, all of which are small and can be hard to detect until the telltale sign of sooty mold development appears on their excrement (honeydew) or …
By Lukasz L. Stelinski and Jawwad A. Qureshi Getting rid of Asian citrus psyllids (ACP) from your grove is almost like trying to remove the sand from a beach. You can make a huge noticeable impact, but getting every last grain of sand will be impossible. What makes the prospect of ACP management so complex is achieving it in a …
In the latest All In For Citrus podcast, Ozgur Batuman talks about his research into biological control of the Asian citrus psyllid (ACP). Batuman is an assistant professor at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Southwest Florida Research and Education Center. ACP control is necessary for management of citrus greening disease, or huanglongbing (HLB). Batuman’s …
By Jawwad Qureshi Management of the Asian citrus psyllid (ACP) is needed in multiple environments, such as organic and conventional production systems and urban areas. However, the tools and approach may be different depending on the circumstances. Chemical control is the primary method used in commercial production to reduce psyllid populations, but the increased use of insecticides negatively affects the …
University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) entomologist Lauren Diepenbrock provides an update on the long-horned beetle, the newest Florida citrus pest. The beetle was discovered in a Hendry County grove in September. Diepenbrock reports that a grove crew worker “hit a branch and the branch fell right off.” After finding a hole in the branch, the …
