Описание

Four species of termites were surveyed and monitored in the Azorean island between 2011 and 2024 by the Azorean Government under two main monitoring programs, "House Inspections" and "Monitoring Traps": the Drywood termite Cryptotermes brevis (Walker, 1853), the Yellownecked dry-wood termite Kalotermes flavicollis (Fabricius, 1793), the European subterranean termite Reticulitermes grassei Clément, 1978 and Eastern subterranean termite Reticulitermes flavipes (Kollar, 1837). The records of C. brevis dominate over the remaining three surveyed species, with 1801 out of the 1832 events (98%). These records are mostly from two islands, Terceira (919 records) and São Miguel (755 records). Three islands (Faial, Pico and Santa Maria) have around 40 records each and São Jorge only seven records. Annual counts for all islands rose from ~ 40 records in 2011 to 154 records in 2024, with a peak of 185 records in 2023. Concerning, K. flavicollis, this was the second most recorded species with 24 records, most of them from São Miguel Island. The two subterranean termites were recorded as expected from the historical data from Faial and Terceira. Now established on every surveyed island, with an upward trajectory in annual record‐counts, C. brevis remains the single greatest urban termite threat in the Azores. Sustained focus on early detection (e.g., year‐round trap checks) and high‐level public awareness (e.g., instructing residents to report tiny, pin‐sized fecal pellets) is vital to prevent further outbreaks of heavily infested structures.

Данные проекта

In 2022, a monitoring program was conducted with the aim of assessing the status of the West Indian drywood termite (Cryptotermes brevis Walker, 1853) throughout the entire archipelago; the Iberian subterranean termite (Reticulitermes grassei Clément, 1978) on Faial Island, in the parish of Angústias; and the Eastern American subterranean termite (Reticulitermes flavipes (Kollar, 1837)) on Terceira Island, in the parish of Lajes. This monitoring was carried out by placing baited stations on every island of the Azores. Additionally, the Termite Infestation Certification System (Sistema de Certificação de Infestação por Térmitas – SCIT) was analyzed, mapping a total of 1,882 certificates that contained evidence of insect damage

Методы сбора

Chromotropic Light Trap Network For the execution of this sampling and monitoring, external traps were placed on public lighting poles and fixtures, in collaboration with the Island Environment and Climate Change Services of the nine islands of the Azores, under the Regional Secretariat for Environment and Climate Change. The traps used consist of a yellow, chromotropic, sticky plastic material (measuring 25 × 20 cm) and were attached beneath the public lighting fixture. The traps were deployed during April and retrieved at the end of September, and were subsequently analyzed by the Regional Secretariat for Environment and Climate Change to confirm the presence or absence of alates (winged, flight-capable) termites. Monitoring was carried out by capturing winged individuals in the traps and performing counts. Infestation Inspection Certificates (SCIT) Since 2011, every home, commercial building or public facility offered for sale or rent in designated “at‐risk” parishes must present a valid Termite Infestation Inspection Certificate (“SCIT”). Trained technicians—graduates of the University of the Azores’ dedicated pest-inspection course—survey interior woodwork (floors, door‐ and window‐frames, skirting boards), attics and crawl-spaces for six key signs of infestation (live insects, alate wings, mud tubes, frass, damage galleries and feeding holes). Results are logged centrally, driving annual updates of geographic risk maps used by municipalities to target preventive treatments and to inform prospective buyers.

Введение In the Azores archipelago, our understanding of termite diversity and their ecological and economic impacts has only recently begun to coalesce. Four invasive species now dominate urban and peri-urban environments: the Yellownecked dry-wood termite Kalotermes flavicollis (Fabricius, 1793), native to the Mediterranean basin and capable of infesting live branches and, under high‐moisture conditions, structural timbers with colonies of up to 1,000 individuals (Ferreira et al. 2013); the dry‐wood termite Cryptotermes brevis (Walker, 1853), the most destructive dry‐wood species in the Caribbean, able to tolerate low moisture and to establish hundreds of small colonies within a single piece of timber (Ferreira et al. 2013; Guerreiro et al., 2014); and two subterranean termites Reticulitermes grassei Clément, 1978, confined so far to the city of Horta (Faial Island), where it builds extensive soil nests and can form multinucleate colonies comprising millions of individuals (Ferreira et al., 2013; Hernández-Teixidor et al., 2024) and Reticulitermes flavipes (Kollar, 1837) restricted so far to Terceira Island (Austin et al., 2012)
