Viruses in the Gut of Asian Citrus Psyllid: Friends or Foes?

Tacy Callies Psyllids, Research

By Ozgur Batuman and Amit Levy Management options for huanglongbing (HLB) are limited and rely heavily on insecticides for controlling Asian citrus psyllid (ACP) populations, even when integrated with other cultural control methods. Chemical strategies are expensive and, if not rotated, can contribute to the development of chemical resistance among ACP populations. In some cases, long-term chemical applications may have …

Getting HLB Material Into Phloem

Ernie Neff HLB Management

University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) plant pathologist Ozgur Batuman discusses efforts to get materials that fight HLB into the citrus tree’s phloem, where it might be most effective. Batuman explains that bacteria that cause HLB “live inside the phloem of citrus. That is very difficult to reach to kill … by conventional methods, such as …

Study Shows Mandarin IPM Needs Work

Len Wilcox California Corner, IPM, Pests

According to a study published in the Journal of Economic Entomology, current integrated pest management (IPM) techniques used in California mandarins may need to be adjusted to allow for differences between mandarins and oranges. The study suggests that following guidelines for oranges may lead to an overuse of pesticides in some situations. Almost all mandarins in America are grown in …

Precision Agriculture Technologies in Citrus

Tacy Callies Pests, Psyllids, Research, Technology

By Yiannis Ampatzidis Citrus growers face issues from an increasing number of pests and diseases. Rapid and accurate tools for early pest and disease detection are needed to improve precision and timely management. Almost all agrochemicals (e.g., pesticides) applied in specialty crop production are made uniformly with conventional spraying equipment, despite the fact that pathogen distribution is typically patchy. Uniform …

Artificial Intelligence Could Help Citrus Growers Detect Psyllids

Daniel Cooper Citrus Greening, HLB Management, Industry News Release, Psyllids, Research, Technology

Precision agriculture engineer Yiannis Ampatzidis sees a day when citrus farmers use artificial intelligence (AI) to detect the pin-sized insects that can infect the fruit’s trees with the deadly greening disease. That day could come in the near future, because Ampatzidis and his research team are starting to perfect a system to detect the potentially deadly Asian citrus psyllid. Citrus …
