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, …
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 …
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, …
Brazilian citrus association Fundecitrus has alerted growers that proper management to combat citrus canker in orchards begins with leafminer control. The leafminer is a pest that has been present in Brazilian citriculture since 1996. According to Fundecitrus researcher Franklin Behlau, the leafminer does not spread citrus canker disease from one plant to another or even to different parts of it. …
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 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 Jawwad A. Qureshi Several insect pests and mites colonize citrus crops in traditional open orchards. Most pests are localized and are suppressed by predators, parasitoids and entomopathogens to levels that are not economically damaging to the crops. The Asian citrus psyllid (ACP) is the primary vector of huanglongbing (HLB) disease. Despite biological and chemical control of ACP, growing a …
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 …
By Lauren Diepenbrock Pest management is a year-round challenge in Florida citrus. With the warm climate, pests are at the ready as soon as plant resources are available to them. With knowledge of invertebrate biology in relation to tree phenology, growers can develop plans to protect fruit and maintain productive citrus trees. HIGHLY PROBLEMATIC PESTS Populations of some highly problematic …
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 …
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 …
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 …
Herb Young enjoyed a 40-year career in the agricultural chemical industry, starting as a technical service representative and eventually becoming a product manager. During those years, he worked on various specialty crops across the country. About 25 years of his career was spent in field research roles. So, experimentation with crops and growing practices comes naturally to Young. He has …
The Christmas freeze event in 2022 affected some insect pests in the cold-hardy citrus region more so than others, according to Xavier Martini. The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) assistant professor spoke about his findings during the recent Citrus Health Forum held at the North Florida Research and Education Center (NFREC) in Quincy. Martini addressed …
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 …
