Formosan Termites Confirmed in Two New Southern California Areas – PCT On-line


RIVERSIDE, Calif.  – Formosan subterranean termites (Coptotermes formosanus) proceed to be on the radar of pest administration professionals in Southern California following affirmation of two extra infestations – one from a home in La Verne, Calif., and the opposite from a home in Hollywood Hills, Calif. The findings have been confirmed by Dr. Chow-Yang Lee and researchers from his lab on the University of California, Riverside Department of Entomology.

As previously reported by PCT, Formosan subterranean termites (FSTs) aren’t native to Southern California nor the USA. Nonetheless, in California they’ve been confirmed in pockets, and lots of entomologists and pest administration professionals imagine they could be underreported within the Golden State.

The latest FST discovery in La Verne, Calif., got here after ProCraft Pest Control, Upland, Calif., was known as by one in all its prospects about a big termite swarm. It turned out the swarm was coming from the next-door neighbor’s dwelling. That home-owner, who owns a lumber firm, constructed their dwelling with quite a few railroad ties. ProCraft proprietor Mike Furlong theorizes that a number of the railroad ties might have been transported from a location that does have Formosan subterranean termites.

ProCraft’s Luke Miller, the service technician who made the FST discovery at a La Verne home.

Furlong was alerted to potential FSTs by ProCraft service technician Luke Miller, who providers the house. “I made a decision to ship it in (to UCR) as a result of it did not match,” Furlong stated. “Only a lighter colour all through, and that doesn’t match drywoods and different subs we see. And the wings appeared off. The coloration was off considerably.”

Dr. Lee was overseas, however his lab technician, Sen Miao, did the measurement and molecular identification. Lee then checked the end result of the ID and confirmed that they have been Formosan subterranean termites. “Mainly, what we did was study the morphology of the pattern beneath the microscope after which carried out evaluation of 16S ribosomal RNA,” Lee stated.

Furlong stated that his buyer’s dwelling was immaculate and in addition constructed on a slab (no crawlspace), so he didn’t discover any harm, however that ProCraft will likely be carefully monitoring that property for FSTs sooner or later. 

Along with the Formosan termites present in La Verne, an FST infestation was confirmed in a Hollywood Hills, Calif., dwelling. The termites have been despatched to UC Riverside by the home-owner after first recognized by Orkin’s Isela Munoz after which by Orkin inspector José Ernesto Aguilar. After receiving the pattern, Dr. Siavash Taravati from University of California Agriculture and Natural Resources (UC ANR) visited the house, the place he discovered extra useless Formosan termites within the storage space within the loft. Nevertheless, no indicators of energetic infestations have been evident throughout visible inspection or when he used Termatrac, a tool that detects tiny actions within the wooden utilizing microwaves know-how.

“It is an all-wood previous home with termites first present in June 2022 in a loft flying round a standing gentle close to a storage door,” he stated. 

Taravati stated that some minor harm was discovered within the panorama on the buried portion of the fence downslope, “however we do not know if they’re from Western subterranean termite or Formosan. On the upslope, dense cowl vegetation have been discovered however the picket retaining partitions have been intact. 

The home additionally has many small damages from drywood termites based mostly on their form and presence of hexagonal fecal pellets.” 

Taravati added that he inspected the crawlspace of the Hollywood Hills dwelling and located no proof of FST harm and that the close by panorama soil was comparatively dry, apart from a number of spots close to sprinklers.
