AB  - Volatile organic compounds from various plants have received popular interest as 
      one of the vector control tools due to their eco-friendliness and 
      insect-repellent activities. In this study, an excito-repellency assay system was 
      used to examine the noncontact repellency, contact excitation, and knockdown (KD) 
      effects of guava leaf (Psidium guajava L.) oil against Anopheles minimus 
      (Theobald), Anopheles epiroticus (Linton & Harbach), and Culex quinquefasciatus 
      (Say). The organic components of guava oil were identified by gas 
      chromatography-mass spectrometry analysis with dl-limonene (17.4%), cymene 
      (5.49%), and alpha-terpinene (5.20%) as the major constituents. At concentrations of 
      2.5 and 5.0%, 100% escape of An. minimus was recorded in the contact assay and 
      96-98% escape in the noncontact assay. Guava oil stimulated potent irritant (92% 
      escape) and repellent (61-86% escape) effects against Cx. quinquefasciatus. A 
      lower repellency action was observed against An. epiroticus (17-20% escape). No 
      KD effect was observed for guava oil against An. minimus and Cx. quinquefasciatus 
      at any concentration. However, An. epiroticus was more prone to KD effects, with 
      the highest percentage KD (44% in nonescape group) observed with 5.0% guava oil 
      in the noncontact assay. Mortalities of 35% and 11% were observed for An. 
      epiroticus in the nonescape groups in the contact and noncontact assays, 
      respectively. Concentrations of 1.0% and 2.5% guava oil led to <2% mortality in 
      An. minimus. Our findings highlight guava oil as a promising plant-based mosquito 
      repellent that can be included in insecticide formulations for future mosquito 
      control programs.
