A citrus tree at a private residence near San Diego, California, has been found to be infected by four Asian citrus psyllids (ACP). Upon testing, the ACP were found to be carriers of the bacterium that causes citrus greening, also known as huanglongbing (HLB). The finding was announced by the California Department of Food and Agriculture’s Citrus Pest and Disease …
Researchers from Sacramento State and the University of California, Riverside are requesting input from citrus industry members to help examine the economics of Asian citrus psyllid (ACP) and huanglongbing (HLB) management in California citrus groves. The research team is looking for growers, advisors and other citrus industry members in California to provide input on overall knowledge of ACP and HLB, …
Researchers at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) are looking to increase the efficiency of known Asian citrus psyllid (ACP) control techniques by using them together. The pairing should help control populations of the insect that spreads huanglongbing (HLB) disease. Bryony Bonning, UF/IFAS eminent scholar and entomology professor, is leading the research funded by a …
To the surprise and consternation of growers and officials, 74 Asian citrus psyllids (ACP) have been discovered in Kern County, California, since June. Local and state officials are concerned about the recent uptick in trappings and are working to find how extensively the infestation has spread. The trappings have been equally dispersed in residential and commercial citrus. Staff from the …
California’s ACP/HLB San Joaquin Valley Task Force reports that an increased number of Asian citrus psyllid (ACP) trap finds have occurred in the southern part of Kern County. The task force made the announcement in an open message to all citrus growers in the San Joaquin Valley. It was published on the Citrus Insider website on Oct. 16. Last month …
For the first time, an Asian citrus psyllid (ACP) carrying the bacteria which causes huanglongbing (HLB) was found in a commercial grove in Riverside County. While the discovery has prompted concern, University of California Riverside Extension Specialist Monique Rivera said that the find has been expected and is not all that surprising. “We’ve had positive trees removed here in Riverside, …
An Asian citrus psyllid (ACP) sample has been confirmed positive for Candidatus Liberibacter asiaticus (CLas), the bacteria that causes huanglongbing (HLB). The sample was collected from a commercial citrus grove in the Woodcrest area of Riverside County. Confirmed by Citrus Research Board’s Jerry Dimitman Laboratory, this single adult psyllid is the first CLas-positive ACP found in a commercial citrus grove …
In the latest All In For Citrus podcast, Ozgur Batuman talks about his research into biological control of the Asian citrus psyllid (ACP). Batuman is an assistant professor at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Southwest Florida Research and Education Center. ACP control is necessary for management of citrus greening disease, or huanglongbing (HLB). Batuman’s …
The California Department of Food and Agriculture (CDFA), working in cooperation with the Sacramento County agricultural commissioner, has placed Sacramento County under a plant pest quarantine for the Asian citrus psyllid (ACP) following the detection of one ACP in Sacramento’s Lemon Hill area. The quarantine prohibits the movement of citrus and curry leaf tree nursery stock and all plant parts, …
Several research projects continue at University of California Riverside to evaluate strategies for better detection of Asian citrus psyllid (ACP). Monique Rivera, assistant cooperative Extension specialist, is looking into something referred to as the ‘edge effect’ and how it pertains to ACP control. “The ‘edge effect’ is basically an ecological term that we’re using in the context of Asian citrus …
Florida citrus growers have begun taking notice of kaolin clay, a powdery white compound, because it can cause Asian citrus psyllids (ACP) to “not take notice” of their groves. Long used to protect other fruit and vegetable crops, kaolin can also conceal citrus trees from hungry psyllids by confusing their visual sensory system, said Michael Rogers, director of the Citrus …
The Asian citrus psyllids (ACP) found last week in a residential area in north Visalia, California, were a breeding population, according to Greg Douhan, University of California Cooperative Extension farm advisor for citrus. The ACP were found in four locations in the city, not in close proximity to any agricultural operations. “Most of the findings found in the San Joaquin Valley …
A large population of Asian citrus psyllids (ACP) and nymphs were found in an older residential area northwest of Visalia, California, last week. With multiple life stages of ACP found, county and state officials have moved into eradication mode immediately. According to the Visalia Times-Delta, 250 ACP were found in four locations. California Citrus Mutual reported that up to 400 …
By Len Wilcox University of California Davis (UC Davis) researchers have identified the sex pheromone of the Asian citrus psyllid (ACP), a discovery which will lead to better methods of controlling the pest. The ACP is a major threat to citrus around the world. The psyllid is a tiny insect with the potential to wreak havoc as it spreads the …
By Jawwad A. Qureshi and Philip A. Stansly More than a decade has passed since 2006, when huanglongbing (HLB) or citrus greening disease was identified in Florida. By then, the disease had already spread widely and went unrecognized due to high psyllid populations and a disease incubation period of months or years between infection and symptom expression. Nevertheless, management of …
Research is looking at what we can learn from the Asian citrus psyllid’s (ACP) history, specifically ACP movement throughout Southern California. Psyllid finds in Central California are mimicking the insect’s history of spread. University of California, Department of Agriculture and Natural Resources held it’s California Asian Citrus Psyllid and Huanglongbing Research and Extension Summit at UC Riverside. The summit was …
By Jawwad A. Qureshi Natural enemies are the beneficial organisms that control insect and mite pests. Citrus trees produce most of their young shoots (flush) for the year in spring and will continue to produce more in summer and fall. Arthropod activity has already started in citrus groves. For example, overwintering Asian citrus psyllid (ACP) adults have started reproducing. Other …
Recent research showed that individual protective covers (IPCs) proved highly effective in reducing Asian citrus psyllid (ACP) populations and thereby preventing HLB infection in three mandarin cultivars. However, overall tree response varied. The research was published in the Journal of the American Society for Horticultural Science. The authors are Saoussen Ben-Abdallah, Susmita Gaire, Ute Albrecht, Ozgur Batuman, Jawwad Qureshi and …
Two adult Asian citrus psyllid (ACP) samples were confirmed positive for Candidatus Liberibacter asiaticus (CLas) in two central California coastal counties on March 10, the Citrus Pest & Disease Prevention Program (CPDPP) reported. CLas is the bacterium that causes HLB. One sample was collected during a routine commodity survey in a commercial citrus grove in the Fillmore area of Ventura …
By Lauren Diepenbrock Citrus under protective screen (CUPS) has provided growers with a profitable method for producing fresh fruit in Florida. Growers who have implemented this system have noted quality fruit production and reduced inputs. However, when changes are imposed to the production environment, they are also imposed to the invertebrate pest complex, which can be either beneficial or detrimental …
