By Jawwad Qureshi The Asian citrus psyllid (ACP, Figure 1) continues to feed on citrus trees infected with citrus greening and spread the disease to newly planted young trees. Therefore, it is not possible to produce a healthy citrus tree in an environment where citrus greening is endemic. Only the citrus under protective screen (CUPS, Figure 2) system allows the …
Repeated evaluations throughout California showed “a massive decline – greater than 70%” in HLB-spreading Asian citrus psyllid (ACP) densities since the inception of a biological control program, a researcher reported recently. Mark Hoddle said the University of California, Riverside (UCR) and the California Department of Food and Agriculture (CDFA) turned to biocontrol because insecticide spraying wasn’t adequately controlling the psyllid. …
By Lukasz Stelinski, Eric Roldan and Kirsten Pelz-Stelinski Use of antibiotics in fruit production is not a new idea, but it has only recently been applied on a larger scale in Florida citrus. The initial labels for huanglongbing (HLB) treatment with antibiotics in Florida citrus were approved in March 2016 in response to significant economic losses caused by HLB. Antibiotics …
A University of Miami (UM) doctoral candidate won third place in the UM College of Engineering’s Rothberg Catalyzer Pitch Competition for creating an instrument to quickly detect airborne traces of citrus greening disease. Shruti Choudhary’s creation, CitrusMimic, would be deployed on farming equipment to continuously draw in air and test for the citrus greening bacteria spread by the Asian citrus …
A California citrus leader believes Georgia will make an ideal home for the Asian citrus psyllid, which vectors the devastating huanglongbing (HLB) disease. “North of Florida, it is colder, and it’s certainly not as suitable a place as Florida is, but the psyllid is still going to be fine. The cold isn’t long enough here to knock the populations out,” …
A wider diversity of weeds and insects in organic Mexican citrus orchards compared to conventional orchards aids in control of the HLB-spreading Asian citrus psyllid (ACP/Diaphorina citri), a Mexican scientist reported recently. HLB is also known as citrus greening disease. “In the organic orchard, there are almost double the species of weeds compared to the conventional orchard,” Carlos Castillejos Cruz …
California’s Citrus Research and Field Trials (CA-CRaFT) program is now accepting Cycle 2 applications from commercial growers. This initiative aims to showcase the efficacy of additional control measures against the Asian citrus psyllid (ACP). ACP is the carrier of the Candidatus Liberibacter asiaticus bacterium causing huanglongbing (HLB) disease in citrus. For Cycle 2, applications will be accepted until program capacity …
A failed field test has led to a major discovery about Asian citrus psyllids (ACP). According to new research, the bacterium that causes HLB disease can interfere with ACP’s sense of smell, rendering some kinds of insect traps useless. The work is currently available as a preprint. HLB, also known as citrus greening, is caused by the Candidatus Liberibacter asiaticus (CLas) bacterium. …
Mexico’s Ministry of Agriculture and Rural Development recently pointed out ways the country has successfully dealt with huanglongbing (HLB), the most devastating disease of citrus worldwide. The ministry reported that the disease has triggered socioeconomic problems in other citrus-producing countries and regions in the Americas, Africa and Asia. “With appropriate agronomic-phytosanitary management, the life of affected trees can be prolonged, …
By Jawwad A. Qureshi, Lauren Diepenbrock and Davie Kadyampakeni Protecting citrus trees from the Asian citrus psyllid (ACP) is critical to reducing the spread and severity of huanglongbing (HLB) disease. The frequent availability of viable shoots in young trees is attractive to psyllid colonization, feeding and oviposition events. UV-metalized reflective mulches reflect ultraviolet light, which is disturbing for some insects …
By Lourdes Pérez Cordero Insects in general are often thought of as pests. Although some organisms of the class Insecta can become harmful to important agricultural crops, not all insects should inherently be considered pests. A pest can be any organism that competes, injures, or spreads diseases to humans, domestic animals and desired plants. Historically, humans have utilized chemical mixtures …

California’s Citrus Pest and Disease Prevention Division (CPDPD) has officially updated the requirements for moving bulk citrus fruit within and from a huanglongbing (HLB) quarantine area to a packer/processor. CPDPD is part of the California Department of Food and Agriculture. Here’s an overview of the newly updated requirements, per the CPDPD’s Citrus Grower/Grove Manager Information page: All fruit, no matter …
Federal and state authorities in early November expanded the Mediterranean fruit fly (Ceratitis capitata or Medfly) quarantine in the Leimert Park area of Los Angeles County, California. The action was taken by the U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS) and the California Department of Food and Agriculture (CDFA) on Nov. 1 and again on Nov. …
By Xavier Martini and Romain Exilien Despite intensive control efforts, the Asian citrus psyllid (ACP), the vector of Candidatus Liberibacter asiaticus, the bacteria causing citrus greening, remains the most devastating pest of citrus. The ACP typically relies on tactile, visual and odor cues to detect its host. By combining an irritant, a visual masking and a true repellent, University of Florida …
By Fernando Alferez, Ute Albrecht, Ozgur Batuman, Jawwad Qureshi and Saoussen Ben Abdallah Individual protective covers (IPCs), which are psyllid-exclusion mesh bags, are increasingly being adopted to efficiently protect newly planted citrus trees from huanglongbing (HLB) infection. However, IPCs typically must be removed after two to three years due to tree growth. Early evidence indicates that brassinosteroids (Brs), a relatively …
Agriculture officials recently established a Mediterranean fruit fly (Ceratitis capitata or Medfly) quarantine and expanded an Asian citrus psyllid (ACP) quarantine, both in California. MEDFLYFederal and state agriculture officials on Oct. 18 established the Medfly quarantine in California’s Los Angeles County. The action was taken by the U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (USDA APHIS) and …
By Amir Rezazadeh Citrus trees face many threats that can impact fruit development and overall tree health. Pests, including aphids, mites and other insects, can damage fruit and transmit diseases. Extreme weather events, such as hailstorms or heavy rains, can cause physical harm, leading to blemishes and reduced market value. In addition, citrus growers have faced persistent challenges because of …
HLB, spread by the Asian citrus psyllid (ACP), has been the scariest and most destructive disease that Florida citrus growers have ever faced. So, it was fitting that entomologist Jawwad Qureshi made a virtual presentation about ACP/HLB on Halloween, often considered the scariest day of the year. Qureshi, a University of Florida Institute of Food and Agricultural Sciences associate professor, …
Recently, the California Department of Food and Agriculture (CDFA) declared an HLB quarantine in Ventura County following the first detections of the disease in the county. In response, the Citrus Pest & Disease Prevention Program (CPDPP) issued a list of HLB resources. The resources are intended to help inform the citrus industry about what changes to expect from the quarantine, …
