The citrus leafminer is a small, hard-to-detect pest that hides during the day and comes out at night to lay its eggs. Though this pest is small, it’s been known to cause severe damage to FL citrus crops. Having a broad-spectrum insecticide at your fingertips could go a long way in protecting your crops. While the citrus leafminer remains a …
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 …
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, …
By Jawwad A. Qureshi, Philip A. Stansly and Lukasz L. Stelinski Pest management has always been important for citrus production in Florida. It has become even more critical following invasion of the Asian citrus psyllid (ACP) and citrus leafminer (CLM), due to their association with huanglongbing (HLB or citrus greening) and canker diseases, respectively. ACP and CLM develop and reproduce …
By Lauren Diepenbrock Pest management is a year-round challenge in Florida citrus. But with knowledge of insect, mite and snail seasonal biology in relation to tree phenology, plans can be developed to protect fruit and maintain productive citrus trees. Populations of some highly problematic pests (Asian citrus psyllid and citrus leafminer) generally increase with flush/new growth development, so targeting peak …
A University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researcher recently highlighted a number of benefits from using silicon as a nutrient for citrus. Muhammad Shahid, assistant professor at the North Florida Research and Education Center, presented silicon research findings at the Citrus & Specialty Crop Expo in August. According to Shahid, silicon is categorized as a plant …
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 …
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 …
University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Associate Professor Xavier Martini recently wrote an article In the Cold Hardy Citrus Connection about management of mites for fresh market citrus. Martini is an entomologist at the North Florida Research and Education Center. An edited version of his article follows. Two types of mites mainly affect citrus production in …
A Nov. 22 Lake County farm tour, hosted by University of Florida Institute of Food and Agricultural Sciences Extension, included a visit to the 13-acre citrus under protective screen (CUPS) site owned by IMG Citrus. Located in Groveland, the facility consists of Ruby Red grapefruit on Swingle rootstock planted in May 2022. Clint Updike, IMG citrus production manager, told farm …

So, experimentation with crops and growing practices comes naturally to Young. He has …
Production in the cold-hardy citrus region is still in its infancy. Growers and industry leaders need events like the Citrus Health Forum to obtain the necessary information to help this young industry continue to flourish. The latest forum took place at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) North Florida Research and Education Center in Quincy …
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, …
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 Management of the Asian citrus psyllid (ACP, Figure 1) is critical because it is responsible for spreading huanglongbing (HLB) disease. Although HLB is established in Florida, it continues to spread through ACP feeding in already infected trees and by infecting newly planted young trees. Some ACP control occurs naturally in the environment by beneficial organisms such as …
The lebbeck mealybug, also known as the hibiscus mealybug, is a pest that has recently become problematic for Florida citrus growers. Extension agent Lourdes Perez Cordero and entomologist Lauren Diepenbrock, both with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS), recently reported on the pest. According to Cordero and Diepenbrock, the lebbeck mealybug feeds by piercing the …
Citrus growers should emphasize leafminer management this year to preserve new flushes. This is especially important for those producers affected by the Christmas freeze event. The management strategy should include pheromone disruptions, which can help reduce pest populations. Xavier Martini, assistant professor of entomology at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) North Florida Research and …
Cold-hardy citrus growers need to protect their trees against the citrus leafminer this year, more so than ever. A lack of control could have negative consequences for trees still recovering from the Christmas freeze last December. Xavier Martini, assistant professor of entomology at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) North Florida Research and Education Center, …
