![]() ![]() Because of its harmfulness and invasiveness, it was rated as one of the top ten pests in 2017 (Wild 2017). In the past four years, it has invaded 47 African countries, 18 Asian countries, and now Australia has also been reported. frugiperda was first discovered in Nigeria and Ghana, Africa in early 2016 and caused USD 13 billion in economic losses in sub-Saharan Africa. The fall armyworm, Spodoptera frugiperda (Lepidoptera: Noctuidae), is native to tropical and sub-tropical areas of the Americas and spread to Mexico, the United States, and Canada in the mid-19th century. These results provide an experimental and theoretical basis for improving light-trapping techniques for managing S. frugiperda, with a maximum distance of no more than 108 m. Therefore, we summarized a proposal of using blue light for light traps to control S. frugiperda to blue light was smaller than that of H. According to the obtained parameters, the trapping distance of S. armigera, further confirmed by the indoor simulation experiment and EC50. frugiperda was significantly lower under a low light intensity of UV light than that of H. The phototactic rates of the two moths increased gradually with light intensity and were not obviously influenced by sex. frugiperda showed the highest average phototactic rate to blue light among five different LED lights. frugiperda, with Helicoverpa armigera as control. In this study, a series of phototactic behavioral assays were carried out and the physical parameters were included to identify phototactic responses of S. Light trapping is a pesticide-free method for pest control and is influenced by many factors, especially wavelength and light intensity. The fall armyworm, Spodoptera frugiperda (Lepidoptera: Noctuidae), is an important migratory pest, causing great losses to agricultural production. Combined with these results and the obtained formula, we summarized a proposal of using blue light for light traps to control S. armigera at a low light intensity of UV light. frugiperda were significantly lower than those of H. frugiperda had the highest average phototactic rate to blue light than other lights. In this study, a series of phototactic behavioral assays were carried out and physical parameters were included to identify the different phototactic behaviors between S. However, present light-trapping methods mainly use UV light, which is effective with Helicoverpa armigera and many nocturnal insects and has displayed a low effect on an important migratory pest, the fall armyworm, Spodoptera frugiperda (Lepidoptera: Noctuidae). Appropriate wavelength and light intensity are the key factors for trapping specific target pests.

Serve up to five oxygen patients by connecting your NewLife Intensity to the SureFlow™ oxygen flow station, an easy-to-use device which allows you to supply medical-grade oxygen to patients at one-time and offers adjustable flow options. NewLife Intensity 10 LPM dual flow units provide additional savings to long-term care facilities with their capability to deliver oxygen to two patients simultaneously from a single concentrator. This 10 Liter stationary oxygen concentrator combines 20 psi outlet pressure and up to 10 LPM of therapeutic oxygen making it ideal for home care use and long-term care facilities where higher oxygen flow is necessary. The NewLife Intensity is the most durable and capable 10 Liter stationary oxygen concentrator on the market today.
