A team of Taiwanese and US scientists warned of “super termites” after a three-year study suggested that two destructive subterranean species are producing hybridized offspring in the wild.
This research, which consisted of lab tests and a three-year field study in Taiwan, was published in the March issue of Heredity.
Coauthor Lee Hou-feng (李後鋒), a professor of etymology at National Chung Hsin University, said last week that the research conducted by the team showed that the two common invasive termite species are 100 percent more fertile and resilient to climate conditions.

Taiwanese subterranean termites and Asian subterranean termites are deemed the world’s most invasive termite species, causing economic damage worth tens of billions of US dollars every year, he said.
The University of Florida’s Fort Lauderdale Research and Education Center previously proved via lab tests that the two termite species have the potential to reproduce fertile hybrids, Lee said.
Taiwanese scientists picked up the research since the two species have for centuries coexisted in Taiwan, a unique proximity not duplicated anywhere else in the world, he said.
Working in collaboration with citizen scientists and companies in the pest control industry, The research team between 2019 and 2021 collected numerous samples of flying termites in Taichung, Chiayi and Yunlin, he said.
The team focused their efforts on these jurisdictions because they showed the highest degree of overlap between the two species, Lee said.
An analysis found that 5 percent of the gathered samples display the traits of Formosan and Asia subterranean termites while being of an intermediate color and size, he said.
The superior fecundity and adaptability to humidity and temperature conditions of the super termites might spell trouble for humans, but an accurate risk assessment would require closer observation, he said.
Tropical Storm Nari is not a threat to Taiwan, based on its positioning and trajectory, the Central Weather Administration (CWA) said yesterday. Nari has strengthened from a tropical depression that was positioned south of Japan, it said. The eye of the storm is about 2,100km east of Taipei, with a north-northeast trajectory moving toward the eastern seaboard of Japan, CWA data showed. Based on its current path, the storm would not affect Taiwan, the agency said.
The Taipei Department of Health’s latest inspection of fresh fruit and vegetables sold in local markets revealed a 25 percent failure rate, with most contraventions involving excessive pesticide residues, while two durians were also found to contain heavy metal cadmium at levels exceeding safety limits. Health Food and Drug Division Director Lin Kuan-chen (林冠蓁) yesterday said the agency routinely conducts inspections of fresh produce sold at traditional markets, supermarkets, hypermarkets, retail outlets and restaurants, testing for pesticide residues and other harmful substances. In its most recent inspection, conducted in May, the department randomly collected 52 samples from various locations, with testing showing
The cosponsors of a new US sanctions package targeting Russia on Thursday briefed European allies and Ukraine on the legislation and said the legislation would also have a deterrent effect on China and curb its ambitions regarding Taiwan. The bill backed by US senators Lindsey Graham and Richard Blumenthal calls for a 500 percent tariff on goods imported from countries that buy Russian oil, gas, uranium and other exports — targeting nations such as China and India, which account for about 70 percent of Russia’s energy trade, the bankroll of much of its war effort. Graham and Blumenthal told The Associated Press
INTEL: China’s ships are mapping strategic ocean floors, including near Guam, which could aid undersea cable targeting and have military applications, a report said China’s oceanographic survey and research ships are collecting data in the Indo-Pacific region — possibly to aid submarine navigation, detect or map undersea cables, and lay naval mines — activities that could have military applications in a conflict with Taiwan or the US, a New York Times report said. The article, titled “China Surveys Seabeds Where Naval Rivals May One Day Clash,” was written by Chris Buckley and published on Thursday. Starboard Maritime Intelligence data revealed that Chinese research ships last year repeatedly scanned the ocean floor east of Taiwan’s maritime border, and about 400km east and west of Guam; “waters that
