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.

AbstractNowadays, the maize weevil Sitophilus zeamais—Motsch 1855 is the most relevant pest found during storage of maize grains. Aiming at protecting the agricultural crops, high amounts of synthetic pesticides are used around the world. In this sense, this work aimed at evaluating the insecticidal and repellent effect of essential oil of Ocotea odorifera (Vellozo) Rohwer (Lauraceae) (O. odorifera (sassafras)) leaves against the maize weevil in maize grains. The essential oil's chemical composition showed that sassafras contains camphor (43%) and safrole (42%) as major compounds. Our results show that sassafras oil was insecticidal and repellent to maize weevil. About 100% mortality was achieved using a concentration of 0.32 μl cm−2, after 24 h of exposure. The LD50 value was 14.1 μl or 0.09 μl cm−2 and the study of the effect on insect mortality at the lethal doses (LD50) showed that after 72 h mortality was 100%. The values of the preference index varied from −0.39 (0.065 μl cm−2) to −0.63 (0.659 μl cm−2), demonstrating that the plant oil presents repellent activity. The repellency bioassay simulating small bins showed the repellent effect level from 0.64 (0.36 μl cm−3) to 0.94 (2.9 μl cm−3). The essential oil of sassafras presented insecticidal and repellency against maize weevil. Although from an economical point of view synthetic chemicals are still more frequently used as repellents, natural products (essential oils) have the potential to provide efficient and safer repellents for humans and the environment.

Main Components

Essential oil of Chinese medicinal herb,Blumea balsamiferaleaves, was found to possess fumigant toxicity against the maize weevils,Sitophilus zeamais. The main components of the essential oil ofB. balsamiferawere 1,8-cineole (20.98%), borneol (11.99%),β-caryophyllene (10.38%), camphor (8.06%), 4-terpineol (6.49%),α-terpineol (5.91%), and caryophyllene oxide (5.35%). Bioactivity-guided chromatographic separation of the essential oil on repeated silica gel columns led to isolate five constituent compounds, namely, 1,8-cineole, borneol, camphor,α-terpineol, and 4-terpineol. 1,8-Cineole, 4-terpineol, andα-terpineol showed pronounced fumigant toxicity againstS. zeamaisadults (LC50= 2.96 mg/L, 4.79 mg/L, and 7.45 mg/L air, resp.) and were more toxic than camphor (LC50= 21.64 mg/L air) and borneol (LC50= 21.67 mg/L air). The crude essential oil also possessed strong fumigant toxicity againstS. zeamaisadults (LC50= 10.71 mg/L air).
