Chris Oswalt details the connection between citrus leafminer (CLM) and citrus canker in the May/June Central Florida citrus Extension newsletter, Citrus from the Ridge to the Valley. He also offers some management tips. “I don’t think we can overstate the effect of leafminer damage on citrus foliage and the increased development of citrus canker lesions on damaged leaves,” the multi-county …
Biological control can have a significant impact on Asian citrus psyllid (ACP) and citrus leafminer (CLM) populations in Florida, a researcher reported in a Nov. 19 virtual meeting. Jawwad Qureshi, associate professor of entomology with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS), also discussed some cultural and chemical controls that work on the pests. ACP Qureshi, …
University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researcher Lauren Diepenbrock recently offered post-hurricane observations and management suggestions for some insects and snails. Diepenbrock is an assistant professor at the Citrus Research and Education Center. BULIMULUS SNAILS Related Bulimulus snail species have been found to lay eggs in the fall after major rain events. Both small and larger …
Hurricane Milton is currently expected to be a major hurricane when it makes landfall on Florida’s west coast late Wednesday night or early Thursday morning. It will likely impact a large portion of the state. In anticipation of the hurricane and its aftermath, Florida Citrus Mutual has canceled its crop estimate luncheon that was scheduled for Oct. 11 in Zolfo …
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 …
By Ernie Neff New tools available to aid in establishment of young citrus groves all have pros, cons and unknowns, entomologist Lauren Diepenbrock told a Citrus & Specialty Crop Expo audience in August. Diepenbrock is an entomologist and assistant professor with the University of Florida Institute of Food and Agricultural Sciences. She opened her presentation by saying insecticides alone are …
The U.S. Department of Agriculture Agricultural Marketing Service (USDA AMS) funded three citrus projects in Georgia for fiscal year 2023. SATSUMA EDUCATIONThe Georgia Department of Agriculture (GDA) received $103,225 for a satsuma education project. GDA will partner with local farmers and produce distributors to increase the availability of Georgia-grown satsuma mandarins in retail locations. The project will work closely with …
By Jawwad Qureshi A wide range of pests colonize citrus crops. Most of these species target tree canopies, and a few feed on the roots. Damage is either direct through feeding on the plant tissues or it can be twofold if the pest is also responsible for transmitting the pathogens of a disease or making conditions favorable for the disease …
Foliar sprays of insecticides timed to citrus flushing provided a significant reduction in Asian citrus psyllid (ACP) populations compared to standard grower practices, researcher Jawwad Qureshi reported. Timing sprays to flushing also led to a reduction in sprays, the University of Florida Institute of Food and Agricultural Sciences associate professor of entomology said in a virtual presentation on Feb. 22. …
By Jawwad A. Qureshi and Salman Al-Shami The citrus under protective screen (CUPS, Figure 1) system is designed so citrus can grow inside screened enclosures to protect it from huanglongbing (HLB) and the Asian citrus psyllid (ACP, Diaphorina citri). ACP is the primary vector of the pathogen responsible for causing HLB, known as citrus greening disease. This vector-pathogen combination is …
By Lauren Diepenbrock, Megan Dewdney, Fernando Alferez, Jawwad Qureshi and Ozgur Batuman Individual protective covers (IPCs) are becoming commonplace in citrus production to support the development of young trees after planting. IPCs are made of fine mesh and are intended to keep Asian citrus psyllids (ACP) off young plants. Because ACP can transmit the pathogen that causes citrus greening/huanglongbing, preventing …
By Lauren Diepenbrock, Megan Dewdney, Christopher Vincent and Davie Kadyampakeni As the threat of potential shutdowns loomed in March 2020, a University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) team put the final plants in the ground, individual protective covers (IPCs) on trees, and kaolin and pesticide applications on a 2.7-acre planting at the Citrus Research and Education …
Highlands County Extension agent Lourdes Pérez Cordero recently offered scouting and management suggestions for citrus leafminers (CLM), Asian citrus psyllids (ACP) and rust mites. The suggestions were part of an article in the January issue of Citrus from the Ridge to the Valley, the Central Florida citrus Extension newsletter. CITRUS LEAFMINERS The emergence of spring and summer flush benefits CLM, …
Citrus under protective screen (CUPS) systems in Florida provide trees significant protection from the Asian citrus psyllid (ACP) and the HLB it spreads. Several other pests are also significantly reduced in CUPS, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers reported. For instance, citrus leafminer (CLM) populations were reduced by more than 80%. Large predators such as …
By Lukasz Stelinski The citrus leafminer (CLM) remains a major pest of citrus throughout Florida. The adults are small, white/silver colored moths about half the size of a typical mosquito (Figure 1). Adults are difficult to spot because of their small size and because they are active only in the evening (dusk) and early pre-dawn hours. CLM adults can be …
By Xavier Martini Citrus leafminer (CLM) is a recurring pest in citrus groves that lays eggs on new growth shoots (flush). After hatching, larvae penetrate directly into the leaf and begin feeding on sap and leaving a serpentine mine in the leaf. CLM population dynamics are mostly driven by flushing pattern, with two flight peaks in early spring and late …
By Jawwad Qureshi Managing the Asian citrus psyllid (ACP) is critical because of its role in spreading huanglongbing (HLB). Biological control is one method for ACP control. It is essential for developing integrated and sustainable pest management strategies. Biological control has always been a vital component of citrus pest management in Florida; understanding its contribution to the mortality of ACP …

Entomologist Lauren Diepenbrock is seeking Florida citrus growers’ help in determining information gaps and future directions for her research on pests. To get that help, she’s asking growers to participate in a survey, which is available here. Diepenbrock, a University of Florida Institute of Food and Agricultural Sciences researcher, would like to have growers take the survey by March 31, …
By Lauren Diepenbrock While Asian citrus psyllids (ACP) are an ongoing concern in Florida citrus due to their role in spreading the bacterium associated with citrus greening, they are not the only pest of concern to growers. Citrus leafminer (CLM) and root weevils are two pests that have been raising concerns and adding to the challenge of managing productive citrus …
