ABSTRACT The aim of this work was to evaluate the insecticidal and repellency activity of the essential oil of Cinnamomum camphora var. linaloolifera Y. Fujita (Ho-Sho) and Cinnamomumcamphora (L.) J Presl.var. hosyo (Hon-Sho), against the Sitophilus zeamais in maize grains. The essential oils were obtained by hydrodistillation and analyzed by GC-MS.The insecticidal activity was determined by the toxicity of different concentrations of essential oils during 24 hours of contact with the insects, in the absence of feed substrate. The Bioassays of repellency were conducted with lethal doses (LD50,LD25,and LD12.5) obtained from insecticidal bioassay. In order to compare the treatments the preference index (PI) was employed. The analysis of the essential oils of Cinnamomum camphora leaves indicated 68% of camphor and 9% of linalool for the variation Hon-Sho and 95% of linalool to the variation Ho-Sho. The variation Ho-Sho presented greatest insecticidal activity than the variation Hon-Sho against the Sitophiluszeamais, with LD50 of 0.35 μL/cm2, whereas in the variation Hon-Sho the ratewas 0.48 μL/cm2. However, considering only the concentrations of linalool and camphor of Ho-Sho and Hon-Sho, the lethal doses’ evaluation of these compounds were similar. The values of the preference index ranged from -0.3 to -0.8 for thevariation Ho-Sho and -0.2 to -0.7 for the variation Hon-Sho. The essential oils evaluated in this work showed repellent activity against Sitophiluszeamais in vitro and in trials performed in mini-silos.

ABSTRACT The present study aimed to assess the effects of the essential oil of Croton pulegiodorus Baill on eight populations of Sitophilus zeamais Motschulsky with different patterns of susceptibility to synthetic insecticides. Populations of S. zeamais were obtained from Sete Lagoas-MG, Jacarezinho-PR, Bom Conselho-PE, Garanhuns-PE, Jupi-PE, Lajedo-PE, São João-PE and Serra Talhada-PE. To estimate the lethal concentrations (LC50 and LC90) of oil for each population, fumigation tests were performed. The susceptibility of S. zeamais to the essential oil varied among populations. Garanhuns and Bom Conselho was considered the susceptibility patterns, presenting the lowest LC50 (3.40 μL L-1 of air) and LC90 (9.60 μL L-1 of air) for the essential oil, respectively. The population from Jupi exhibited the highest LC50 (14.49 μL L-1 of air) and LC90 (19.60 μL L-1 of air) for C. pulegiodorus. The resistance ratio ranged from 1.84 for the São João to 4.26 for the Jupi population. Thus, the essential oil of C. pulegiodorus showed fumigant activity, causing mortality in all S. zeamais populations used.

Anacyclus pyrethrum is a herbaceous plant that belongs to the Asteraceae family. The focus of the present study is to extract the essential oil from this plant, to determine its chemical composition and to evaluate its insecticidal activity against the larvae of the mosquito Culex pipiens. The essential oil from A. pyrethrum collected from the region of Bensliman in Morocco was extracted by hydrodistillation and analyzed by gas chromatography coupled to mass spectrometry were studied. Essential oil yield obtained by hydrodistillation was 0.09%. The major aroma constituents were Spathulenol (20.47%), Germacrene D (16.48%), Caryophyllene oxide (13.20%), 4(14)-Salviale-1-one (8.27%) and Caryophyllene 4(14),8(15)-dien-5α-ol (7.30%). The larvicidal test carried out according to a methodology based on the standard protocol of the World Health Organization was studied on 4th instar larvae of C. pipiens and showed that A. pyrethrum essential oil possesses remarkable insecticidal properties.  After 24 hours of exposition, larvicidal assays revealed a 100% mortality of C. pipiens larvae. The dose of 40 μL/mL was toxic enough to cause 100% larval mortality of C. pipiens. The lethal concentrations LC50 and LC90 calculated for the essential oil studied were of the order of 14.79 μL/mL and 19.95 μL/mL, respectively. To control mosquitoes, this essential oil extracted from A. pyrethrum might be used as a natural insecticide and therefore could be an alternative to synthetic insecticides already present on the market.
