Última Insecticidal activity of citronella grass essential oil on Frankliniella schultzei and Myzus persicae Ciência e Agrotecnologia Pinheiro,Patrícia Fontes; Queiroz,Vagner Tebaldi de; Rondelli,Vando Miossi; Costa,Adilson Vidal; Marcelino,Tiago de Paula; Pratissoli,Dirceu. The thrips, Frankliniella schultzei, and green peach aphid, Myzus persicae, cause direct damage to plants of economic importance and transmit phytoviruses, causing large economic losses. Chemical constituents of essential oils present a wide range of biological activities. The aim of this work was to evaluate insecticidal activity of essential oil from citronella grass, Cymbopogon winterianus, on F. schultzei and M. persicae. This essential oil was obtained by steam distillation and components were identified by GC/FID and GC/MS. A Potter spray tower was used to spray insects with the essential oil. The major constituents are geraniol (28.62%), citronellal (23.62%) and citronellol (17.10%). Essential oil of C. winterianus at 1% (w v-1) causes mortality in...

Khao Dawk Mali 105 (KDML 105) (Oryza sativa L) is well known as Thai jasmine rice. The major aroma component of KDML 105 is 2-Acetyl-1-pyrroline (2AP). Besides the 2AP, KDML 105 contains various volatile components which contribute aroma and flavor to the rice. Moreover, hydrocarbons, aldehydes, ketones, and alcohols are also found in the rice sample. Due to the complex nature of the sample, some volatile components which co-elute with rice matrix components are not easily identified using traditional GC-MS. GCxGC-TOFMS is a new technique that increases peak capacity and enhances peak sensitivity. The research described here used GCxGC-TOFMS to identify components in the complex mixture of KDML 105 grain sample extracts. Two columns with different...
