Hot temperatures and dry conditions in some parts of the Southeast add up to ideal conditions for mite populations to increase in citrus groves. Lauren Diepenbrock, University of Florida Institute of Food and Agricultural Sciences assistant professor and entomologist, said citrus can tolerate some spider mite pressure. Increased pressure, though, can leave an impact. “You can handle some amount of …
Some species of snails in Florida groves, normally seen on irrigation emitters and tree trunks, have recently “taken up residency in young citrus trees,” University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Extension agents Chris Oswalt and Ajia Paolillo reported. Here’s a summary of what the agents wrote in a recent UF/IFAS Central Florida citrus Extension newsletter: Once …
University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) specialists are alerting Georgia citrus growers about an invasive pest that’s impacting Florida’s crop. Lebbeck mealybugs have yet to navigate their way to Georgia. But it is only a matter of time, says Lauren Diepenbrock, UF/IFAS assistant professor and entomologist. “It’ll get up to Georgia probably. We’re doing our best …
Citrus growers are working to address California red scale populations, as second-generation crawlers have emerged in the San Joaquin Valley. University of California Cooperative Extension Area Citrus IPM Advisor Sandipa Gautam said a tool for tracking degree days in Kern, Tulare, Fresno and Madera counties can be a helpful resource for growers. Gautam explained that the hot and dry conditions …
Nicole Quinn recently joined the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) as an assistant professor of entomology. She’ll specialize in the biocontrol of invasive pests, insects and mites at the Hayslip Biological Control Research and Containment Laboratory. The lab is at the UF/IFAS Indian River Research and Education Center (IRREC) in Fort Pierce. Quinn will begin …
A portion of Los Angeles County has been placed under quarantine for the Oriental fruit fly following the detection of 14 flies in the North Hills area of the San Fernando Valley.

By Xavier Martini Planting wildflowers in and around fields is known to provide food resources and habitats for beneficial arthropods like pollinators and predators of pests. In two locations (Lake Alfred and Monticello), University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers tested whether planting native Florida wildflowers next to citrus grove windbreaks could improve natural pest control …
The U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) in late June announced updates regarding Mexican fruit fly (Mexfly) quarantines in Texas: On April 29, APHIS and the Texas Department of Agriculture (TDA) established a Mexfly quarantine in Lyford, Willacy County, Texas.

California’s commercial citrus groves remain free of HLB disease 14 years after Asian citrus psyllids (ACP) were first detected there. The state’s Citrus Pest and Disease Prevention Program (CPDPP) described that as “no small feat” in its recently released 2020-21 annual report. “The past fiscal year presented its fair share of headwinds for citrus-growing operations,” the report stated. “From pandemic-induced …
