Below you'll see everything we could locate for your search of “asian citrus psyllid”
A recent article by the São Paulo Research Foundation explains how a potent compound might aid in controlling the Asian citrus psyllid, the vector of citrus greening disease. In São Paulo, greening is managed in part by controlling the psyllid. In an attempt to manipulate psyllid behavior, a team of scientists discovered α-copaene, a molecule present in large quantities in …
By Jawwad A. Qureshi All citrus pests in Florida have natural enemies, although some are more effective at biological control than others. University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers have been studying the activity and impact of natural enemies on pest infestations in traditional open production systems and protected systems such as citrus under protective screen …
During the recent Florida Citrus Industry Annual Conference, Kirsten Pelz-Stelinski, director of the University of Florida Institute of Food and Agricultural Sciences Mid-Florida Research and Education Center, presented evaluations of trunk-injected antimicrobials for HLB management. She said the purpose of these antimicrobial treatments is a short-term or stop-gap approach to keep the current inventory of Florida citrus trees in the …
By Muhammad A. Shahid and KeAndre Leaks Silicon (Si) is an emerging powerhouse in citrus production, offering wide-ranging benefits for plant health, fruit quality and stress resilience. While not traditionally considered essential, silicon was officially recognized as a “plant beneficial substance” in 2012 by the American Association of Plant Food Control Officials. Its inclusion as an approved input by the …

Citrus Research and Development Foundation President Morgan McKenna Porter said individual protective covers (IPCs) give newly planted trees a “fighting chance” against huanglongbing (HLB) and serve as a bridge until HLB-resistant trees are available. “IPCs are not flawless, but they certainly can be optimized,” Porter said. “I have the ability to plant a young tree and put an IPC over …
The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Southwest Florida Research and Education Center in Immokalee hosted a citrus field day on April 10. The event showcased the research being conducted at the center. One of the tour stops featured individual protective cover (IPC) research led by Fernando Alferez, UF/IFAS associate professor of citrus horticulture. Thanks in …
Growers gathered in Avon Park for the annual Florida Citrus Growers’ Institute at South Florida Community College in early April. Scientists from the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) presented updates on their work and the latest efforts to help in the fight against HLB. New this year, the scientists also hosted learning stations to further …
Citrus under protective screen (CUPS) offers benefits that go beyond its initial purpose of Asian citrus psyllid (ACP) exclusion. Steven Callaham of Dundee Citrus Growers Association discussed the advantages and sustainability of this form of citrus production. Rapid tree growth is a major benefit, according to Callaham. “It has been documented that trees inside of CUPS grow about 2.5 times …
Fundecitrus researcher Silvio Lopes and agricultural engineer Orlando Lucato Neto recently addressed how climate variation impacts the development of citrus shoots — the HLB-spreading psyllid’s main food source. They also discussed the incidence of psyllids in Brazilian orchards. Lopes said climate impacts the three components of HLB disease: the citrus plant, the vector insect (psyllid) and the causative bacteria. “The …
Now is the time for Florida citrus growers to implement management tactics to control the Asian citrus psyllid (ACP), the insect that vectors citrus greening, also known as huanglongbing (HLB). ACPs are currently in low populations across Florida’s citrus-producing region. That means growers should act now to protect their crop from the insect’s impact, says Chris Oswalt, University of Florida …
The Highlands County Citrus Growers Association hosted its annual banquet on March 6 in Sebring. The event drew a good crowd to catch up on the association’s activities. Two of the featured speakers during the event discussed alternative trunk-injection therapies to the current standard of oxytetracycline (OTC). Tanishka Aglave, a sophomore at Strawberry Crest High School, received the H. Robert …
One Florida citrus industry leader is impressed with Georgia’s burgeoning industry. Rick Dantzler, Citrus Research and Development Foundation chief operating officer, believes Georgia’s industry can continue to grow as long as it manages citrus greening effectively. He stressed eradication when speaking about citrus greening, also known as huanglongbing (HLB), at the annual meeting on Feb. 25. “Georgia’s potential is bright …
The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) hosted its annual Citrus Nutrition Day in January at the Citrus Research and Education Center in Lake Alfred.

The U.S. Department of Agriculture (USDA) announced an investment of more than $70 million in the Plant Protection Act program. This includes funding of 357 projects in fiscal year 2025. The work will strengthen the country’s defenses against plant pests and diseases, safeguard the U.S. nursery system, and enhance pest detection and mitigation efforts. Part of the funding is going …
Recently, the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) reported research on the development of a new type of citrus tree that can fight off the HLB-spreading Asian citrus psyllid (ACP). The genetically modified tree has only been tested in the lab and the greenhouse, but the research looks promising. The approach involves inserting a gene into …
The citrus section in the February issue of Specialty Crop Grower is coming soon. It’s full of features for growers to dive into.
