Efficacy of different light-emitting diodes (LEDs) attached to yellow sticky cards to capture the whitefly trialeurodes vaporariorum = Eficacia de diferentes diodos emisores de luz (LEDs) unidos a trampas adhesivas amarillas para la captura de la mosca blanca Trialeurodes vaporariorum
Published 2018“…However, the attractiveness depends on various factors such as the reflected intensity (brightness) and the hues of yellow color (wavelength) of the trap surface, which is often influenced by environmental conditions and may sometimes affect the capture of white flies.There fore, the use of light emitting diodes (LEDs) can be a significant complementary tool to strengthen attractiveness and the selectivity of these cards. …”

LED flashlight technology facilitates wild meat extraction across the tropics
Published 2020“…However, hunters in many countries throughout the tropics have recently begun to switch to brighter and more efficient light‐emitting diode (LED) flashlights. Such brighter spotlights stimulate the freeze response of many species, and improved battery life allows hunters to pursue game more often and for longer periods of time. …”

Investigation of the global transportation of Culicoides biting midges, vectors of livestock and equid arboviruses, from flower-packing plants in Kenya
Published 2026“…Trapping was undertaken at each stage of production (rootstock, propagation, inside growing greenhouses, in the packing-house, inside cold-storage rooms, during transportation) using Centers for Disease Control and Prevention (CDC) Light Emitting Diode (LED) light traps. Hand-held aspirators were used to obtain individual insects directly from flowers and around composting sites, while emergence traps studied insect emergence from compost, leaf litter and flowers discarded at quality control checkpoints. …”
