Formosan Termites Confirmed in Two New Southern California Places – 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) will not be native to Southern California nor the USA. Nonetheless, in California they’ve been confirmed in pockets, and lots of entomologists and pest administration professionals consider they could be underreported within the Golden State.

The current FST discovery in La Verne, Calif., got here after ProCraft Pest Control, Upland, Calif., was referred to as by certainly one of its prospects about a big termite swarm. It turned out the swarm was coming from the next-door neighbor’s dwelling. That house owner, who owns a lumber firm, constructed their dwelling with quite a few railroad ties.

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 mentioned. “Only a lighter shade all through, and that doesn’t match drywoods and different subs we see. And the wings seemed 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 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 mentioned.

Furlong mentioned that his buyer’s dwelling was immaculate and likewise constructed on a slab (no crawlspace), so he didn’t discover any injury, however that ProCraft can be intently 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 house 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 outdated home with termites first present in June 2022 in a loft flying round a standing mild close to a storage door,” he mentioned. 

Taravati mentioned that some minor injury 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 primarily based 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 injury and that the close by panorama soil was comparatively dry, apart from a couple of spots close to sprinklers.
