More reports of fall armyworm sightings have been received from across Taiwan, the Council of Agriculture said yesterday as it stepped up efforts to eliminate the moth larvae.
As of 11am yesterday, 65 sightings had been reported nationwide since the first case was confirmed on Monday last week, up by 13 from a day earlier, officials from a council task force told a news conference.
The sightings, which were all of the larval form of the crop-destroying pest, have been reported in 17 of the nation’s 22 administrative areas, and the larvae were destroyed and buried in 28 of the cases, the officials said.

Only Keelung, Kaohsiung, Hsinchu City, Chiayi City and Nantou County have not reported sightings of fall armyworms, which authorities suspect rode air currents from China or Vietnam to Taiwan.
The officials said that measures have been taken to eliminate first-generation larvae before they can take root in corn and rice fields.
Five hundred pheromone traps have been deployed to attract mature fall armyworms and help authorities wipe them out, the officials said.
The larvae were first detected on a farm in Miaoli County — the first time they have been found in Taiwan — after a visitor reported seeing them to the local government.
If fall armyworms arrive in large numbers, sweetcorn and rice fields on Taiwan proper, and sorghum and wheat fields in Kinmen County would be particularly vulnerable, with potential annual losses of up to NT$3.5 billion (US$111 million), the council said.
Since 2016, fall armyworms have caused economic losses in the Americas, Africa and Asia, including 18 Chinese provinces.
Tropical depression TD22, which was over waters south of the Ryukyu Islands, is likely to develop into a tropical storm by this morning and pose a significant threat to Taiwan next week, the Central Weather Administration (CWA) said yesterday. The depression is likely to strengthen into a tropical storm named Krathon as it moves south and then veers north toward waters off Taiwan’s eastern coast, CWA forecaster Hsu Chung-yi (徐仲毅) said. Given the favorable environmental conditions for its development, TD22’s intensity would reach at least typhoon levels, Hsu said. As of 2pm yesterday, the tropical depression was about 610km east-southeast of Taiwan proper’s
Four factors led to the declaration of a typhoon day and the cancelation of classes yesterday, Taipei Mayor Chiang Wan-an (蔣萬安) said. Work and classes were canceled across Taiwan yesterday as Typhoon Krathon was forecast to make landfall in the southern part of the country. However, northern Taiwan had only heavy winds during the day and rain in the evening, leading some to criticize the cancelation. Speaking at a Taipei City Council meeting yesterday, Chiang said the decision was made due to the possibility of landslides and other problems in mountainous areas, the need to avoid a potentially dangerous commute for those
Typhoon Krathon, a military airshow and rehearsals for Double Ten National Day celebrations might disrupt flights at Taiwan Taoyuan International Airport in the first 10 days of next month, the airport’s operator said yesterday. Taoyuan International Airport Corp said in a statement that it has established a response center after the Central Weather Administration issued a sea warning for Krathon, and urged passengers to remain alert to the possibility of disruptions caused by the storm in the coming days. Flight schedules might also change while the air force conducts rehearsals and holds a final airshow for Double Ten National Day, it added. Although
SEMICONDUCTORS: TSMC is able to produce 2-nanometer chips and mass production is expected to be launched by next year, the company said In leading-edge semiconductor manufacturing China is behind Taiwan Semiconductor Manufacturing Co (TSMC) by at least 10 years as the Taiwanese chipmaker’s manufacturing process has progressed to 2 nanometers, National Science and Technology Council (NSTC) Minister Wu Cheng-wen (吳誠文) said yesterday. Wu made the remarks during a meeting of the Legislative Yuan’s Education and Culture Committee when asked by Democratic Progressive Party Legislator Wu Pei-yi (吳沛憶) about a report published in August by the Chinese version of Nikkei Asia that said Taiwan’s lead over China in chip manufacturing was only three years. She asked Wu Cheng-wen if the report was an accurate
