Insecticide Efficacy of Green Synthesis Silver Nanoparticles on Kuwayama (Hemiptera: Liviidae).

Kuwayama (Hemiptera: Liviidae) is a vector of Jagoueix et al. and Teixeira et al., causal agents of the critical yellow dragon disease or Huanglongbing (HLB), which affects citrus production worldwide. Recently, green synthetic nanoparticles have emerged as a potential alternative to control of agricultural insect pests. The insecticide effect of silver nanoparticles (AgNPs) on 2nd instar nymphs of under laboratory and greenhouse conditions was evaluated. Mortality was recorded 24, 48, and 72 h after application on nymphs under both laboratory and greenhouse conditions. The laboratory results showed that AgNPs caused 97.84 and 100% mortality at 32 and 64 ppm, respectively, 72 h after treatment. In the greenhouse, AgNPs caused 78.69 and 80.14% mortality using 64 and 128 ppm 72 h after application. This research is the first to evaluate the green synthesis AgNPs on and are a promising strategy to control the pest.
