Light-emitting Diodes (LED) as Luminous Lure for Adult Spodoptera frugiperda (J. E. Smith, 1797) (Lepidoptera: Noctuidae)

Abstract

The capture of insects through luminous sources can represent another option for integrated pest management (IPM). The purpose of this study was to verify the attractiveness of different-colored Light-Emitting Diodes (LED) on adult Spodoptera frugiperda. The research was conducted at the

Blue Light Attracts More Spodoptera frugiperda Moths and Promotes Their Flight Speed

“…Some other insects have also been reported to be sensitive to blue light and can be captured by the blue LED traps, such as the white-backed planthopper (Sogatella furcifera), brown planthopper (Nilaparvata lugens), rice weevil (Sitophilus oryzae), angoumois grain moth (Sitotroga cerealella), and thrips [28,33,34]. However, our results were inconsistent with the results of other studies; Zhang et al (2023) found that S. frugiperda preferred UV light [18], and Nascimento et al (2018) and reported that S. frugiperda preferred green light [16,17]. Potential reasons for this discrepancy could include variations in the type of light source, light intensity, duration of light treatment, and the physiological status of the insect [31,32].…”

“…Defining the sensitive wavelengths of pests and setting the target sensitive light source helps develop efficient, specific, and ecological security light trapping techniques [9]. As with most insects, existing studies indicated that S. frugiperda is sensitive to blue, green, or UV light, albeit with mixed results [12,13,[16][17][18]. Insect spectral sensitivity can affect various life activities, including orientation, navigation, foraging, hunting, courtship, egg-laying, and other behavioral activities [19,20].…”
