“…In each replicate the treatments were randomly rotated to avoid the interference of external factors. The repellent indexes were calculated according to Restello et al (2009), in which the oil is classified as neutral if the index is between -0.10 to 0.10, attracting if it is between 0.10 to 1.00 and repellent if it is between -1.00 to -0.10.…”

The maize weevil (Sitophilus zeamais Motschulsky) is one of most important pest of stored seeds worldwide, but its current control method is based on the use of synthetic insecticides, usually leading to undesirable problems such as insecticide residues on treated food, human intoxications, and insect resistance development. Therefore the search of friendly alternative methods is required. The aim of this study was to assess, under laboratory conditions, the insecticidal properties of Peumus boldus Molina, Laurelia sempervirens (Ruiz & Pav.) Tul., and Laureliopsis philippiana (Looser) Schodde essential oils against S. zeamais. The phytochemical analysis of the three essential oils showed 1,8-cineole, safrole and methyleugenol as the common components; all of them documented with insecticidal activity from essential oils from other plant species. The highest toxicity (100% mortality) of these three oils acting as a contact insecticide was observed at 24 h exposure at 4% concentration. The estimated LC 50 values for P. boldus, L. sempervirens, and L. philippiana were 0.37, 1.02, and 0.28 µL g -1 , respectively. Peumus boldus exhibited the highest fumigant activity with 100% adult mortality at 30 µL oil L -1 air. At ≥ 0.5% (v/w) concentration, all essential oils showed repellent activity. These three essential oils showed a promissory insecticidal activity against the maize weevil.

“…Evaluation of the insecticidal action after 12 h of exposure of Sitophilus zeamais to different concentrations of hydroalcoholic extracts of crambe under controlled conditions of temperature and photoperiod Nascimento, Diniz Filho, Mesquita, Oliveira, and Pereira (2008) found 96 to 100% of dead Sitophilus insects exposed to Tagetes patula extract in vapor form. Restello, Menegatt, and Mossi (2009) studied the effect of the essential oil of T. patula on Sitophilus mortality and found 100% of dead insects. Silva, Melo, Pessoa, Almeida, and Gomes (2012) observed a raise in Sitophilus mortality as the rates of Momordica charantia (L.) extract increased, reaching 100% mortality when applying 10 mL of the extract.…”

The objective of this work is to evaluate the insecticidal and attractiveness of concentrations of hydroalcoholic extract of crambe grains on Sitophilus zeamais, and its effect on the physiological quality of corn seeds. The experiments were conducted at the Laboratory of Entomology and Seeds of the Assis Gurgacz University Center, in Cascavel, PR. The evaluation of attractiveness and insecticidal effect were evaluated using DIC, with 4 treatments (0, 5, 15 and 25% extract concentration) and 10 or 5 replications, respectively, totaling 40 experimental plots for the insect attractiveness test and 20 Experimental plots for the test of the insecticidal effect. For the experiment on the physiological quality of corn seeds submitted to the extracts, a DIC was set up in a 4 × 4 factorial scheme, factor 1 being the storage time of the seeds (0, 30, 60 and 90 days) and factor 2, the concentrations (0, 5, 15 and 25%), with 4 replicates, totaling 64 plots. Data were submitted to ANAVA, and means adjusted to regression or submitted to the Tukey test at 5% of probability, using the statistical program ASSISTAT®. The results evidenced the treatment with a hydroalcoholic extract in the concentration of 25% as the one with the highest insecticidal effect, and extract at 15% concentration yields a higher percentage of germination, normal seedlings, and mass of seedlings than the control. At 25% concentration, the extract do not negatively influence any of the parameters analyzed. Storage time above 60 days stimulates germination, mass and length of maize seedlings.

“…Conforme o modelo ajustado, Y= 13,1947*ln(x)+38,0385 (r 2 = 0,1949) a morte de 90% dos insetos foi alcançada com a dose aproximada de 52 µL em 20 g de grãos de feijão, ou seja, 2,6 L t -1 . Os resultados corroboram com os obtidos por Restello et al (2009) que, avaliando a atividade inseticida de Tagetes patula sobre Sitophilus zeamais, nas concentrações de 0, 5, 10, 20, 30 e 50 μL por placa de Petri, concluíram que nas maiores concentrações do óleo essencial (30 e 50 μL) a mortalidade dos insetos foi de 100%, reduzindo para as menores concentrações. Mazzonetto & Vendramim (2003), com o objetivo de verificar o efeito inseticida dos pós de 18 espécies vegetais em relação à Acanthoscelides obtectus (Say), na proporção 0,3 g de pó de cada espécie vegetal para 10 g de feijão, também concluíram que os pós de C. ambrosioides e de C. sativum são altamente tóxicos aos adultos, causando 100% de mortalidade até o quinto dia de contato com os insetos.…”

R E S U M OCom este trabalho se avaliaram o índice de preferência e o efeito inseticida do óleo de carqueja doce (Baccharis articulata) sobre o caruncho do feijão (Acanthoscelides obtectus). Para a realização do experimento foram utilizados insetos não sexados, com idade entre 20 e 50 dias. O óleo essencial foi extraido da parte aérea da planta pelo método de hidrodestilação. O experimento foi conduzido conforme o delineamneto inteiramente casualizado, com 6 repetições, em esquema fatorial 6 x 3 e 6 x 7 (dose x tempo), respetivamente, para repelência e para atividade inseticida. Os testes de repelência e da atividade inseticida foram realizados com as doses de 0, 10, 20, 30, 50 e 100 µL de óleo essencial em 20 g de grãos de feijão sendo a avaliação realizada depois de transcorridas 24, 48 e 72 h para a repelência e após 1, 6, 12, 24, 48, 72 e 96 h para a atividade inseticida. Os resultados demonstram que a dosagem, o tempo de exposição e a interação tiveram efeito significativo na mortalidade dos insetos. Em relação à dosagem, seu aumento proporcionou incremento logaritmico na taxa de mortalidade sendo verificada, na dose aproximada de 52 µL, a morte de 90% dos insetos. O tempo de exposição de 35 h provocou a morte de 90% dos insetos. Também, foi observado efeito repelente do óleo essencial nas dosagens e tempos de exposição estudados.Insecticide and repellent activity of the essential oil from carqueja doce on bean weevil A B S T R A C TThe present study evaluated the preference index and insecticidal effect of oil "Carqueja doce" (Baccharis articulata) on the bean weevil (Acanthoscelides obtectus). For the experiment, insects not sexed aged between 20 and 50 days were used. The essential oil was extracted from the aerial parts of the plant by the hydrodistillation method. The experiment was conducted in a completely randomized design with 6 replications in a factorial scheme 6 x 3 and 6 x 7 (dose x time), respectively, for preference index and insecticidal effect. Tests of repellency and insecticidal activity were conducted with doses of 0, 10, 20, 30, 50 and 100 µL of essential oil in 20 g of beans, being the evaluation carried out after 24, 48 and 72 h for repellency and after 1, 6, 12, 24, 48, 72 and 96 h for the insecticidal activity. The results showed that the dose, exposure duration and interaction had significant effect on insect mortality. Regarding the dose, the logarithmic increase in the mortality rate was produced by the increase in dose, with an approximately 52 µL dose which recorded death in 90% of the insects. The exposure time of 35 h caused the death of 90% of insects. Also, the essential oil repellent effect was observed at doses and exposure times studied.
