“…For instance, the attractiveness of a single 70‐W high‐pressure sodium lamp (96 lm W −1 ) is approximately 20 m away from the light source (Degen et al., ). Attraction to light sources has been described in terrestrial insect species (e.g., moths: Altermatt et al., ; beetles: Wakefield et al., ; de Medeiros et al., ). This ‘flight‐to‐light’ behavior varies, however, according to sex, mating status, type of lighting, or species.…”

The alternation of light and dark periods on a daily or seasonal time scale is of utmost importance for the synchronization of physiological and behavioral processes in the environment. For the last 2 decades, artificial light at night (ALAN) has strongly increased worldwide, disrupting the photoperiod and its related physiological processes, and impacting the survival and reproduction of wild animals. ALAN is now considered as a major concern for biodiversity and human health. Here, we present why insects are relevant biological models to investigate the impact of ALAN. First the phenotypic responses to ALAN and their underpinning mechanisms are reviewed. The consequences for population dynamics, and the community composition and functioning are described in the second part. Because ALAN provides new and widespread selective pressure, we inventory evolutionary changes in response to this anthropogenic change. Finally, we identify promising future avenues, focusing on the necessity of understanding evolutionary processes that could help stakeholders consider darkness as a resource to preserve biodiversity as well as numerous ecosystem services in which insects are involved.

“…The differential attractiveness of different light colours and bulb types to different insect orders and families as observed in the present study which focused on A. africana have been documented [6], [16] and this have been useful in the management of the insect orders/families using light traps. Light traps using UV light have been reported to be very effective in insect sampling [8] but the high cost of UV lamps has led to its steady replacement by LEDs which have also be found to be effective and efficient in attractiveness to insects [14]. Owens [11] reported that blue coloured light is most attractive to insects.…”

“…Different insect light traps have been developed over the years from light sources such as mercury vapour lamps, gas lamps and fluorescent UV light tubes predominantly for pest management purposes [19]. But LED technology is being steadily used to replace the afore-mentioned due to its efficiency, low energy consumption, lower cost, among others [14], [20]. Conventional light traps are relatively inexpensive and with minimal effort, light traps yield large number of insect specimen [19] and hence an effective, and eco-friendly means of pest management [9].…”

“…Although the phototactic response of nocturnal insect to artificial light are not without its negative impact on the ecosystem and insect diversity as it makes the species more vulnerable [11], inhibits a lot of bio-processes [12] among others, artificial light have been used in insect traps to study insect population dynamics and diversity, sample population of pest species, delimitate infested areas, among others [13]. Most research on the attractiveness of insects to artificial light have been on temperate environment and only few have evaluated their responses at species level [14]. Thus, considering that red pumpkin beetle is largely nocturnal, the present study investigated the bulb light colour and type which is most attractive to the insect with the aim of providing such basic information which could be instrumental in its integrated pest management strategies and/or used to harvest the species for scientific studies.…”

Red pumpkin beetle (Aulacophora africana Weise) is an important defoliator and vector of pathogens to its numerous crop hosts. Control had largely been by synthetic insecticides with their attendant consequences on man and the environment thus necessitating scientific studies on environmental-friendly management strategies. The experiment was conducted in the Research Farm of Federal University Wukari in the month of May 2019 with the aim of evaluating the attractiveness of A. africana to Light-emitting diode (LED) and Incandescent Light bulb colours. Five colours (red, yellow, green, blue and white) were used for the study. Each colour light was properly projected on 2 metre vertical screen (made of white polyethene) placed one meter above the ground. A setup without bulb served as the control. The light traps were arranged in a completely randomized design (CRD) in 6 replicates and ran simultaneously for six hours (1800 to 2400hrs). The pumpkin beetles attracted were collected in tubs containing soapy water. A. africana collected were counted and recorded according to bulb type and colour. Samples were identified at the Insect Museum of Ahmadu Bello University, Zaria. Among the Incandescent bulbs, White colour was most attractive to A. africana (4.30±0.38) while red attracted the least (0.71±0.01). Among LED bulbs, Blue was most attractive (3.99±1.01) while Red also attracted the least (0.78±0.03). Overall, LED attracted more pumpkin beetles than Incandescent bulb even though Student Newman Keul’s test indicates that the difference between them was due to random variation (p = 0.16). Correlation and regression analyses indicated increase in insect attraction with increased light intensity. The results, therefore, suggest that white Incandescent or blue LED bulb colours can be incorporated into insecticidal light traps to suppress their population/attract them away from host plants or fixed into ordinary light traps to harvest the insect for scientific studies.

“…Reducing the light intensities of street lights could also benefit invertebrates by decreasing flight-to-light behaviour, thereby lowering the risk of mortality from exhaustion and predation, as well as preventing disruptions to biological cycles [ 58 , 59 ]. To reduce the ecological impact on invertebrates, it has been advised that LED street lights should be dimmed to 50% of their original output (less than 14 lux) and adhere to a part-night lighting scheme, i.e.…”

Emerging lighting technologies provide opportunities for reducing carbon footprints, and for biodiversity conservation. In addition to installing light-emitting diode street lights, many local authorities are also dimming street lights. This might benefit light-averse bat species by creating dark refuges for these bats to forage and commute in human-dominated habitats. We conducted a field experiment to determine how light intensity affects the activity of the light-opportunistic Pipistrellus pipistrellus and light-averse bats in the genus Myotis. We used four lighting levels controlled under a central management system at existing street lights in a suburban environment (0, 25, 50 and 100% of the original output). Higher light intensities (50 and 100% of original output) increased the activity of light-opportunistic species but reduced the activity of light-averse bats. Compared to the unlit treatment, the 25% lighting level did not significantly affect either P. pipistrellus or Myotis spp. Our results suggest that it is possible to achieve a light intensity that provides both economic and ecological benefits by providing sufficient light for human requirements while not deterring light-averse bats.
