Light-Trap Catch of Insects in Connection with Environmental Factors

Abstract

This chapter deals with the connection between the light-trap collection of insects and the environmental factors that influence the trapping. These factors are as follows: the solar activity and its effects on the Earth (solar activity featured by Q-Index and the 2800 MHz radio flux, ionospheric storms and atmospheric radio noises, the interplanetary magnetic field sector boundaries, UV-B radiation of the Sun and geomagnetic indices), the moon phases and the polarized moonlight, the weather (macrosynoptic weather situations, weather fronts and air masses, weather events, weather elements), and air pollutants. The presented results show that these all modify the volume of captured insects.

Light-Trap Catch of Turnip Moth (Agrotis segetum Denis et Schiffermüller, 1775) in Connection with the Night Sky Polarization Phenomena

“…Clouds are also taken into account in its calculation [32]. The clouds data were provided by the Annals of the Hungarian Meteorological Service.…”

Pheromone Trap Catch of Fruit Pest Moths Influenced by the Geomagnetic Disturbance Storm Time (Dst)

“…Therefore, we published our research results in a book in connection with environmental factors such as temperature, air pollutants, weather fronts, polarized moonlight, ozone, height of the tropopause, ultraviolet B radiation, geomagnetic G9 index and the solar Q index [18].…”

Increasing catches of adult moth pests (Lepidoptera: Tortricidae) in pome fruit with low‐intensity LED lights added to sex pheromone/kairomone lure‐baited traps

“…Key factors influencing moth catch in light traps are light intensity and radiation spectrum; temperature, wind speed, moonlight, and relative humidity; and diurnal behaviours (Bowden, 1982;Kammar et al, 2020;Kim et al, 2019;Nowinszky & Puskás, 2017). Some practical limitations reported with the use of lights in traps have been both a bias for male over female moths (Altermatt et al, 2009;Garris & Snyder, 2010) and the often extensive catch of nontarget species in light traps (Bian et al, 2018;Ma & Ma, 2012;Nabli et al, 1999).…”
