“…Response behaviors and phototactic mechanisms of insects to different light sources are the main objectives of light-trap technology in order to develop pest control technology using new light sources such as LEDs. Wavelength selectivity and high intensity of LEDs enable them to be specifically designed for targeting pests, protecting biodiversity and the environment [ 26 , 35 ]. S. frugiperda showed the highest average phototactic rate to blue light among the five different LED lights.…”

“…Four relationships between phototactic rate and light intensity, i.e., positive correlation, negative correlation, wavy correlation, and uncorrelation were discovered in different insects [ 22 , 23 , 24 , 25 ]. Therefore, it is necessary to study the species-specificity of phototactic behavior, light source, and light intensity in different species [ 20 , 26 ].…”

The fall armyworm, Spodoptera frugiperda (Lepidoptera: Noctuidae), is an important migratory pest, causing great losses to agricultural production. Light trapping is a pesticide-free method for pest control and is influenced by many factors, especially wavelength and light intensity. In this study, a series of phototactic behavioral assays were carried out and the physical parameters were included to identify phototactic responses of S. frugiperda, with Helicoverpa armigera as control. It was found that S. frugiperda showed the highest average phototactic rate to blue light among five different LED lights. The phototactic rates of the two moths increased gradually with light intensity and were not obviously influenced by sex. In addition, the phototactic rate of S. frugiperda was significantly lower under a low light intensity of UV light than that of H. armigera, further confirmed by the indoor simulation experiment and EC50. According to the obtained parameters, the trapping distance of S. frugiperda to blue light was smaller than that of H. armigera to UV light. Therefore, we summarized a proposal of using blue light for light traps to control S. frugiperda, with a maximum distance of no more than 108 m. These results provide an experimental and theoretical basis for improving light-trapping techniques for managing S. frugiperda.

“…Addition of LEDs has been shown to increase trap catch of a variety of insect species [ 38 , 39 , 40 , 41 , 42 ]. Previous use of white LEDs has been to enhance collections of adult D. citri on yellow sticky traps placed in dark shipping containers [ 43 ].…”

Laboratory assays were conducted to evaluate responses of Diaphorina citri to various aspects of visual cues associated with traps in an effort to improve trap effectiveness. Addition of white or UV violet but not yellow light-emitting diodes (LEDs) increased attraction to standard yellow adhesive traps moderately (11–17%), with no difference in attraction between white or UV violet LEDs. Addition of a black border on yellow traps enhanced collections. However, there were no differences between attraction to black patterns on traps. Comparisons were made between different commercial paints, some with UV-reflecting properties or fluorescence. A yellow paint with UV reflectance, used for painting bird decoys (decoy yellow), was more attractive than the standard yellow Olson sticky trap. Addition of white or green pigment to increase intensity or enhance green reflectance, respectively, did not increase attraction. Alteration of reflectance of Olson traps with addition of UV-reflecting or fluorescent pigments did not enhance attraction of D. citri. In field comparisons, decoy yellow and fluorescent yellow sticky traps were more attractive to D. citri than Olson yellow.

“…The autodissemination device in the study was designed with features to enhance both visual and olfactory stimuli since they are major factors in whitefly behaviour. Visual cues in whiteflies are important in long distance responses while plant volatiles facilitate short distance orientation (60,61). The designed autodissemination device was yellow, based on the colour preference of T. vaporariorum adults (62)(63)(64).…”

The efficiency of an autodissemination technique in controlling adult whiteflies, Trialeurodes vaporariorum Westwood (Hemiptera: Aleyrodidae) on tomato, Solunum lycopersicum was investigated with previously identified potent fungal isolates of Metarhizium anisopliae ICIPE 18, ICIPE 62 and ICIPE 69 under screenhouse or semi-field conditions. The autodissemination device was inoculated with dry conidia of the M. anisopliae isolates, while control insects were exposed to a fungus–free device. Sampling for conidia uptake, conidial viability and persistence, and insect mortality was done at 1, 2, 3, 5 and 8 days post–exposure, and collected insects were monitored for mortality over ten days. Overall, mortality was higher in insects exposed to ICIPE 18 (62.8%) and ICIPE 69 (61.8%) than in those exposed to ICIPE 62 (42.6%), with median lethal times, (LT50) ranging between 6.73–8.54 days. The control group recorded the lowest mortality rates (18.9%). A general linear reduction in conidial viability with exposure time was observed, although this was more pronounced with M. anisopliae ICIPE 62. Insects exposed to M. anisopliae ICIPE 69 also recorded the highest conidia uptake, hence selected for further evaluation with a T. vaporariorum attractant volatile organic compound, (E)–2–hexenal. The volatile inhibited fungal germination in laboratory compatibility tests, therefore, spatial separation of M. anisopliae ICIPE 69 and (E)–2–hexenal in the autodissemination device was conducted. The inhibitory effects of the volatile were significantly reduced by spatial separation at a distance of 5 cm between the fungus and the volatile, which was found to be more suitable and chosen for the subsequent experiments. Results showed that (E)–2–hexenal did not influence conidia uptake by the insects, while fungal viability and the subsequent mortality variations were more related to duration of exposure. The fungus–volatile compatibility demonstrated with spatial separation provides a basis for the optimisation of the volatile formulation to achieve better T. vaporariorum suppression with an excellent autodissemination efficiency when used in the management of whiteflies under screenhouse conditions.
