1. Project of Taoyuan International Airport Corporation: ‘Entrusted Planning and Design for RIFA Control’
Taoyuan International Airport is located in the Dayuan District. In 2004, Taoyuan International Airport determined that the area around Taoyuan Airport, the airport traffic lane, and some parts of the lawn dividing the running chute were invaded by RIFA. The project team has achieved remarkable results after years of prevention and control work. The entire airport area has been lifted from the list of management by the government in May 2018. However, because Taoyuan International Airport is located in the Dayuan District of Taoyuan City, and the current RIFA population distribution and density in the district is still relatively serious, Taoyuan International Airport is still in an area susceptible to RIFA recurrence. The goal of the project team is thus to continue to assist Taoyuan International Airport in the prevention and control of RIFA in the entire airport area, including the manpower planning and execution in the control and investigation field operation, planning for the types of prevention and control agents, method suggestion and execution, RIFA monitoring execution and control rate reporting, assistance in reports required by the competent authorities, and checking related matters on RIFA prevention and control.

3. Project of the Division of Science and Technology: ‘Discussion and Solution Strategies on the Ant Infestation Problems in the Qianshan Caused by the Impact of Climate Change on the Ecology of Qianshan and the Changes in the Community’
Natural disasters on slopes arising from climate change and man-made development pressure have caused the fragmentation of landscape, ecological fragmentation, and habitat loss, causing slopes in Qianshan, Taiwan, an ecologically fragile area. In addition, recent emerging ant infestation problems have appeared in Qianshan towns in south-central Taiwan. Ants pour into houses like streams, and flying ants invade homes like black mist. Such abnormal ecological responses are warnings of the gradual loss of ecological health in Taiwan. This project integrates multiple domains. It takes the ant infestation problem of the Qianshan residents as the starting point to comprehensively examine the hidden landscape fragmentation, ecological loss, and development pressure behind the ant infestation problem. Using the ecosystem service on the slopes as the research framework, key biofacies in habitat are investigated, landscape changes analysed, indicators established, environmental fragility and ecological potential examined, etc. In addition, in response to the logic of the impact of the ant infestation problem on the industry and tourism in the mountain village communities, a Qianshan agricultural production system with potential for ecosystem services and human well-being are established taking climate change as the background.

4. Project of the Division of Science and Technology: ‘Reshape the Prevention and Control of Global Invasive Species: Positioning Taiwan as a Hub for the Prevention and Control, Prediction, and Education of RIFA in Asia’
This study uses further data model analysis and establishment of an innovative RIFA invasive platform for the ongoing scientific debate on the causes of the RIFA global invasion, making significant contributions to the prevention of RIFA, its agricultural and economic impacts, and the development of science in Taiwan. This study successfully discovered the pattern of the elimination of RIFA in Taiwan and revealed the proliferation hotspots and paths. In addition, a smart RIFA notification platform was developed, and a harmful ant detection and AI image automatic identification app system was introduced to improve the efficiency and accuracy of the detection of front-line investigators, volunteers, farmers, and the public, so that the sources of infection can be detected early for prevention and control. Through GIS, social network analysis, and foreign and domestic RIFA distribution information, this study has made the following major discoveries: (1) RIFA are mainly distributed across general roads, rice fields, and storage. (2) The way of invasion is through ports with high shipping volume and those having tight connections with high-shipping-volume ports. (3) The main reasons of island-type proliferation in Kinmen were road construction, regional construction, and city development. Therefore, a major part of this research involves assisting the Bureau of Inspection and Quarantine in distributing epidemic prevention resources. This team has been participating in the inter-departmental meetings of the Bureau of Inspection and Quarantine.

5. Project of the Division of Science and Technology: ‘Development of Microbial Control Technology of Agricultural Pest Ant’
The purpose of this project is the development and application of microbial control for the increasingly serious pest ants in the agricultural environment. Especially considering the development of sustainable agriculture and organic agriculture, this project investigates the design, development, and application of microbial agents for pest ants on crops, and develops its practical value and commercial potential. As biological control is an environmentally acceptable strategy that can reduce the number of pest ants as well as economic losses, entomopathogenic fungi provide an environmentally friendly alternative to chemical pesticides. However, compared with chemical pesticides, the relatively slow action of fungal pathogens hinders their wide use. The project team consists of professional academic research units and vector prevention and control management companies. In addition to the excellent research and development capabilities of academic units, the team has valuable experience in practical applications and commercial development in the industry. On the one hand, the fruitful academic research results can be shared with the industry to promote industrial upgrading; on the other hand, the economic benefits in the market and commercial value of such technology products can be developed so that this technology can truly gain global popularity. The research project has found that the ant pathogen AN_dt1901 (Aspergillus sp. A) has the characteristics of rapidly infecting the nest and killing the major pest ants in the current agricultural environment, Dolichoderus thoracicus. It has the potential to be used in the microbial control of pest ants in agricultural land. These research results have been published in one paper in SCI and have also been used in one submitted SCI paper; they have also been used in two applied for invention patents.

Forty-eight to 96 hours after Dolichoderus thoracicus is infected by four kinds of fungi. After AN_dt1901 is used on Dolichoderus thoracicus, hyphae and conidia will grow on the body.

6. Project of the Bureau of Animal and Plant Health Inspection and Quarantine, Council of Agriculture: ‘Development of Core Technologies and Establishment of Safety Assessment Model of the Agricultural Spraying Drone Industry Chain–Field Trials for Using Agricultural Drones to Control RIFA through the Management of Drone Pesticide Spraying Delegation System’
In areas with a large-scale RIFA invasion, bait spreading is currently still the main prevention and control mode. However, in the RIFA prevention and control area, there are still many locations with special terrains (hills and steep slopes, rivers, valleys, fenced farmland, military control areas, etc.) where personnel and current dune buggies cannot perform control tasks. These areas are easily ignored. In many years, due to the terrain restrictions in many prevention and control areas, the coverage rate of prevention and control agents has only reached approximately 70%–75%. Furthermore, these areas may have not been controlled for many years due to terrain factors, resulting in loopholes in the prevention and control and becoming the source of the recurrence of the epidemic. Therefore, this project is mainly to assist in the establishment of the operation specifications for the use of agricultural drones in RIFA pesticide spraying on large areas or special terrains. In addition, the registration and management system for pesticide spraying delegation for prevention and control, through the interface for unmanned aerial vehicle spraying management data, was established.
   
Two unmanned aerial vehicles (UAV) designed according to the specifications and requirements. The MG-1P (left) can carry 10–20 kg of bait, and KK-02 (right) can carry 6–8 kg of bait.

7. The National Natural Park Management Office/Shoushan National Natural Park Plan of Survey, Monitoring, and Controlling Yellow Crazy Ants
The coastal forests and the Qijin Seawall in the Shoushan National Natural Park of Kaohsiung are the natural habitats of terrestrial crabs. However, Anoplolepis gracilipes (Smith, 1857), commonly known as the yellow crazy ants, have been found in these areas in recent years. A 2018 terrestrial crab survey found that Anoplolepis gracilipes had invaded and spread in the terrestrial crab hotspots of these wetlands. Research reports that these invasive alien ants had infested and caused serious ecological damage on Christmas Island, west of the Australian mainland, and other Pacific islands, specifically threatening the existence of the local terrestrial crab population. In 2020, the bait trap technique was used to investigate the distribution and density of yellow crazy ants in three terrestrial crab hotspots in the coastal areas and the Qijin Seawall in the Shoushan National Natural Park of Kaohsiung. The results showed that yellow crazy ants appeared in all three terrestrial crab hotspots, and the infestation was the most serious in the windbreaks around the seawall of the Qijin Back Hill. Implementation of the Yellow Crazy Ants Controlling Plan with Insect Traps in Shoushan Natural Park started in 2021 to further investigate ant nests in the windbreaks around the seawall of the Qijin Back Hill, where the population density of these ants was higher. The results showed that the yellow crazy ants in the Qijin Back Hill had formed super colonies. In the 2022 plan, the project is focusing on areas with high densities of the yellow crazy ants in the windbreaks surrounding the seawall of Qijin Back Hill, and plans to control these high densities of ants with liquid baits and insect growth regulators. To evaluate the control effect, insect traps and baits will be deployed for investigating and monitoring the invasive and foraging yellow ant populations. The distribution of yellow crazy ants will be investigated in the Mount Banping and the Northern Shoushan military control areas, which are the natural habitats of terrestrial crabs.
