“…and C. imicola than either the 220‐V or 12‐V traps fitted with various coloured LEDs. The greater attractiveness of UV light is a well‐known phenomenon in a number of insect species (Pohe et al ., ), including C. imicola (Venter & Hermanides, ).…”

Culicoides biting midges (Diptera: Ceratopogonidae) are vectors of a range of orbiviruses that cause important veterinary diseases such as bluetongue and African horse sickness. The effective monitoring of Culicoides species diversity and abundance, both at livestock and near potential wildlife hosts, is essential for risk management. The Onderstepoort 220-V ultraviolet (UV) light trap is extensively used for this purpose. Reducing its power requirements by fitting low-energy light-emitting diodes (LEDs) can lead to greater flexibility in monitoring. A comparison of the efficiency of the 220-V Onderstepoort trap (8-W fluorescent UV light) with the efficiency of the 220-V or 12-V Onderstepoort traps fitted with red, white, blue or green LEDs or a 12-V fluorescent Onderstepoort trap demonstrated the 220-V Onderstepoort trap to be the most efficient. All the results showed nulliparous Culicoides imicola Kieffer females to be the dominant grouping. Despite the lower numbers collected, 12-V traps can be used in field situations to determine the most abundant species.

“…Szanyi 2018, 2019). Researchers generally use mercuryvapour lamps and black light lamps for collecting caddisflies and also moths (Blahnik and Holzenthal 2004;Calor and Mariano 2012) since the attraction of caddisflies to near-ultraviolet radiation has been known for a long time (Chernyshev 1961;Mikkola 1972;Blomberg 1976;Walker and Galbreath 1979;Pohe et al 2017). Although between them mercury-vapour lamps are seen more efficient (Mikkola 1972;Blomberg 1976;Walker and Galbreath 1979), but shorter wavelength light sources generally attract higher were caught only with mercury-vapour (MV) and UV2 light sources.…”

“…The high attractivity of the mercury-vapour lamp for caddisflies (Mikkola 1972;Blomberg 1976;Walker and Galbreath 1979) and the role of its UV spectra were also proven (e.g., Chernyshev 1961;Calor and Mariano 2012;Pohe et al 2017), thus this trap type and black light lamps became the most widely used standard light source types in caddisfly sampling (Blahnik and Holzenthal 2004;Calor and Mariano 2012). According to Mikkola (1972) the eyes of Trichoptera are similar to Lepidoptera and sensitive for 350-600 nm wavelength, with a maximum around 550 nm, but the effect of spectral distribution of light sources on caddisflies is poorly known.…”

The artificial light sources are useful tools for sampling night active insects, however, they also possess potential environmental risks in their habitats. To test their applicability and evaluate environmental risk for caddisflies (Trichoptera), the attractivity of different portable light traps working with LED, UV and mixed-white light sources was studied and compared with attractivity of traditionally used mercury-vapour lamp (in Jermy-type light trap), which is tool of sampling and street-light. Analysing 1135 caught individuals of 19 species light sources emitting different wavelength spectra showed different attractivity and selectivity on caddisflies both on species and family levels. Attractivity of mercury-vapour lamp was generally lower than the other tested light sources. We found that the most attractive wavelength range for caddisflies is between 360 and 407 nm. One of the tested LED and mixed-white lamps together could cover this spectrum and a high and wide spectral peak of mixed-white light source between 375 and 391 nm resulted additional catches considering both species and number of individuals. Lamps emitting between 360 and 407 nm may be both a useful tool for sampling caddisflies and dangerous source of light pollution along lowland water courses where the sampled species are common and widespread.

The mayfly Acanthophlebia cruentata of Aotearoa, New Zealand, is widespread in Te Ika-a-Māui North Island streams, but has never been collected from South Island despite land connection during the last glacial maximum. Population structure of this mayfly might reflect re-colonisation after volcanic eruptions in North Island c1800 years ago, climate cycling or conceal older, cryptic diversity. We collected population samples from 33 locations to estimate levels of population genetic diversity and to document phenotypic variation. Relatively low intraspecific haplotype divergence was recorded among mitochondrial cytb sequences from 492 individuals, but these resolved three geographic-haplotype regions (north, west, east). We detected a signature of isolation by distance at low latitudes (north) but evidence of recent population growth in the west and east. We did not detect an effect of volcanic eruptions but infer range expansion into higher latitudes from a common ancestor during the last glacial period. As judged from wing length, both sexes of adult mayflies were larger at higher elevation and we found that haplotype region was also a significant predictor of Acanthophlebia cruentata size. This suggests that our mitochondrial marker is concordant with nuclear genetic differences that might be explained by founder effect during range expansion.
