“…Medeiros et al, (2001) confirmed that a combination of mineral oil and β-cyfluthrin was effective for the management of whitefly nymph (B. tabaci of Race -B) on melon plants. The results of current investigation are also supported by Lin et al (2009), who observed that β-cyfluthrin applied in combination with imidacloprid (0.5 %) reduced 92.70 per cent of silver whitefly population on tomato in green house condition. Similarly, efficacyof β-cyfluthrin on leafhopper was also reported by Kumari et al (2005), Sinha and Sharma (2007) and Satpath and Akhilesh (2010) on okra (A. esculentus) crop.…”

A field experiment was conducted to evaluate the efficacy of different insecticides viz., bifenthrin, flubendiamide, fipronil, quinalphos, pronofos and β-cyfluthrin against white fly ( Bemisia tabaci) of okra (Abelomoschus esculentus) by spraying twice. Among the insecticides evaluated, β cyfluthrin at 18.75 g a.iha -1 was found to be the effective by registering 57.00 and 54.21 per cent reduction of whitefly (B. abaci) during first and second sprays, respectively. Further β-cyfluthrin at 18.75 g a. i ha -1 was subjected to dissipation studies by collecting okra (A. esculentus) fruit samples at interval of zero, one, three, five, seven, 10 and 15 days after last spray. Results of the dissipation studies showed that the initial deposits of β-cyfluthrin (18.75 g a.iha -1 ) in okra (A. esculentus) fruit sample was registered to be 0.11 mg kg -1 and dissipated to below detectable level (BDL) within five days after spray.

“…Thus, biorational methods of aphid control will be required where organic production systems are intended. Previous studies have shown that alternative products, such as entomopathogenic fungi (LOUREIRO; MOINO JÚNIOR, 2006;STEINKRAUS et al, 2002), natural oils, and plant product derivates (BAGAVAN et al, 2009;EL SHAFIE;BASEDOW, 2003;LIN et al, 2009;MAREGGIANI et al, 2008;SANTOS et al, 2004), have the potential to control cotton aphids. Based on the requirements for organic production, the utilization of natural insecticides is one way to control cotton aphid.…”

The control and protection of cotton plants using natural insecticides against the colonization by Aphis gossypii Glover (Hemiptera: Aphididae)

ABSTRACT. The cotton aphid, Aphis gossypii Glover (Hemiptera: Aphididae), is a key pest of cotton, irrespective of the use of conventional or organic management. In organic systems, however, the use of synthetic insecticides is not allowed, increasing the difficulty of controlling this pest. This work evaluated aphid control and the ability of products to prevent aphid infestation using natural insecticides compared to a standard synthetic insecticide. The control trial was conducted with four products [Beauveria bassiana (Boveril ® ), neem oil (Neemseto ® ), and cotton seed oil compared to thiamethoxam (Actara ® )], and untreated plants served as the control group. The trial testing the efficacy of these products in preventing aphid infestation was conducted using the same products, excluding Boveril ® . The evaluations were conducted 72 and 120h post-treatment for the efficacy and the protection against colonization trials, respectively. The aphid control by cotton seed oil, Neemseto ® , and thiamethoxam was similar, with 100% control being achieved on the thiamethoxam-treated plants. Regarding the plant protection against aphid colonization, the insecticide thiamethoxam exhibited a better performance compared to the other tested products with steady results over the evaluation period. The natural products exhibited variable results with low protection against plant colonization throughout the evaluation period.Keywords: Insecta, organic cotton, cotton aphid, alternative control, population growth rate.Controle e proteção de plantas de algodão com inseticidas naturais contra a colonização de Aphis gossypii Glover (Hemiptera: Aphididae) RESUMO. O pulgão Aphis gossypii Glover (Hemiptera: Aphididae) é uma importante praga do algodoeiro, independente do sistema de cultivo convencional ou orgânico. Entretanto, no cultivo orgânico não é permitido a utilização de inseticidas sintéticos, o que dificulta o controle desta praga. Assim, avaliou-se o controle e a proteção da planta à infestação pelo pulgão com inseticidas permitidos em cultivo orgânico. O experimento de controle empregou três inseticidas naturais [Beauveria bassiana (Boveril ® ), óleo de nim (Neemseto ® ) e óleo de algodão comparado ao inseticida sintético tiametoxam (Actara ® )]. O experimento visando a proteção da planta à infestação foi conduzido com os mesmos inseticidas exceto o Boveril ® . As avaliações foram realizadas após 72 e 120h para os experimentos de controle e de proteção da planta, respectivamente. O controle do pulgão 72h após a aplicação foi similar entre óleo de algodão, Neemseto ® e Actara ® e atingiu 100% de controle com o Actara ® . Em relação à proteção da planta contra a colonização, o Actara ® destacou-se com maior proteção das plantas quando comparado aos demais inseticidas, sendo a eficiência mantida em todos os intervalos de avaliação. Já os demais tratamentos apresentaram variabilidade com relação à proteção ao longo dos intervalos de avaliação.Palavras-chave: Insecta, algodão orgânico, pulgão do algodoeiro, controle alternati...

“…This prevents normal nerve transmission and causes paralysis followed by death ("Knockdown") (Colom et al, 2007). Lin et al (2009) observed similar effects in whitefly nymphs, Bemisia tabaci Gennadius (Homoptera: Aleyrodidae) after spraying A. squamosa seed oil. Shrinking and dryness effect were observed in the insect body.…”

This study aimed to verify the insecticidal activity and determine the LC 50 of hydroethanolic extracts from Annona montana leaves and seeds on the black aphid, Aphis craccivora. The experiment was conducted in a greenhouse. Annona montana leaf and seed extracts were obtained by solvent extraction using 70% ethanol. The following spray treatments were applied on the black aphid nymphs: Hydroethanol (HE) extracts from leaves at concentrations of 2.5; 5; 10; 15%, and EH extracts from seeds at 0.5; 1.0; 1.5; 2%; Neemax ® and distilled water (control). Results showed the presence of insecticidal effect of both extracts on A. craccivora nymphs. The HE from leaves was more efficient at the concentration of 15%, with 78% mortality of nymphs. In the case of HE from seeds, the largest mortality was obtained at the concentration of 2%. The acute toxicity of A. montana extracts on A. craccivora nymphs was 7.69 for HE from leaves and 0.55 for HE from seeds. Therefore both extracts of A. montana may be indicated to the control of the agricultural pest (A. craccivora).Key words: Annonaceae; Aphididae; botanical insecticide Bioatividade de extratos de Annona montana Macfad sobre o pulgão-preto do feijão-caupi (Aphis craccivora Koch) RESUMOObjetivou-se verificar a atividade inseticida e determinar a CL 50 dos extratos hidroetanólicos de folha e semente de Annona montana, sobre o pulgão-preto, Aphis craccivora. O experimento foi realizado em casa de vegetação. Os extratos de folhas e sementes de A. montana, foram obtidos por extração com solvente etanol a 70%. Sobre as ninfas do pulgão-preto foram aplicados via pulverização os tratamentos: Extratos hidroetanólico (EH) de folhas na concentração de 2,5; 5; 10; 15% e, (EH) de sementes a 0,5; 1,0; 1,5; 2%; Neemax ® e água destilada (testemunha). Os resultados apontaram o efeito inseticida de ambos extratos sobre as ninfas de A. craccivora. O EH das folhas apresentou maior eficiência na concentração a 15%, com 78% de mortalidade das ninfas, para o EH das sementes o maior índice de mortalidade de ninfas foi obtido com a concentração de 2%. A toxicidade aguda dos extratos de A. montana, sobre as nifas de A. craccivora, foram de 7,69 para os EH de folhas e de 0,55 para os EH de sementes. Portanto ambos os extratos de A. montana podem ser indicados no controle da praga agrícola (A. craccivora).
