Sodium chloride reduces the viability of eggs, larvae, and pupae of Spodoptera frugiperda, as well as delays its development

The control of fall armyworm (Spodoptera frugiperda) populations involves the application pesticides that cause several unwanted effects to humans and other animals, as well environment. Sodium chloride (NaCl) has been used in agriculture potentiate toxicity pesticides. Here, NaCl on viability eggs, larvae, pupae, development S. frugiperda were evaluated. treatment with 0.15 M caused a 35% reduction egg hatching ingestion artificial diet containing salt mortality caterpillars, pre-pupae, delayed insects. larval, pre-pupa pupa stages elongated by about 2, 1 0.8 days, respectively. Additionally, significant pupae body weight was recorded groups treated at 0.62 mg/g 3.12 mg/g. Despite these effects, did not affect adults their reproductive performance. Food deterrent assay revealed acted phagostimulant agent. In conclusion, reduces eggs damage survival carterpillars interferes insect development.
