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 por Castresana, Jorge Eduardo, Puhl, Laura Elena

“…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 por Bowler, M., Beirne, C., Tobler, M.W., Anderson, M., DiPaola, A., Fa, J.E., Gilmore, M.P., Lemos, L.P, Mayor, P., Meier, A., Menie, G., Meza, D., Moreno Gutierrez, D., Poulsen, J.R., Souza Jesus, A. de, Valsecchi, J., El Bizri, H.R.

“…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. …”

How to improve the soilless cultivation of sweet basil looking at light and nutrition? por Säll, Hedvig

“…The study aimed to explore various light and nutrient regimes in order to assess their effects on morphology, growth rate (RG), EO composition and nutrient uptake of basil grown in a hydroponic system. Light emitting diode (LED) lights of blue and red were used and to generate various light treatment coloured cellophane are added. …”

Morphological and Pigment Responses to Far-Red and Photosynthetically Active Radiation in an Olive Cultivar Suitable for Super-High-Density Orchards por Ladux, Federico J., Gonzalez, Carina Veronica, Trentacoste, Eduardo Rafael, Searles, Peter Stoughton, Rousseaux, María Cecilia

“…Arbequina) were exposed to low (L) or high (H) PAR with or without lateral FR supplementation (L+FR, L-FR, H+FR, H-FR) using neutral-density shade cloth and FR light-emitting diode (LED) modules. Total plant and individual organ biomass were much lower in plants under low PAR than under high PAR, with no response to +FR supplementation. …”

Investigation of the global transportation of Culicoides biting midges, vectors of livestock and equid arboviruses, from flower-packing plants in Kenya por Stokes, J.E., Labuschagne, K., Fèvre, Eric M., Baylis, M.

“…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. …”
