“…However, due to the impacts and the development of strains resistant to the products, it has become necessary to use in rotation insecticides with different modes of action, as well as techniques that can assist in integrated pest management (IPM) (Jacobson et al, 2009;Gunning and Moores, 2010;Perry et al, 2011;Shind et al, 2011;Yang et al, 2013).…”

Exposure of Helicoverpa armigera to sublethal concentrations of insecticides can cause physiological deficiencies manifested by reduced longevity, development, fertility and fecundity. Research on the sub-lethal effects, to identify the non-lethal negative impacts of insecticides on pests can provide practical information for integrated management. The objective of this study was to determine the lethal concentrations and sublethal effects of insecticides on larval development and reproduction of H. armigera. The insecticides were diluted in water and applied via immersion of soybean leaf discs directly in the solution for three second, subsequently provided to the larvae maintained under controlled conditions for a period of 48 h. For surviving larvae, artificial diet was provided with daily evaluation until pupation. The pupae obtained were weighed after 24 h and transferred to Petri dishes, covered with filter paper until the adult phase, to evaluate longevity and pupal viability. For the assessments related to oviposition, couples were separated in polyvinyl chloride (PVC) cages and fed with 10% honey solution; the counting of eggs was done every two days, until the end of the oviposition period. All of the insecticides tested presented lethal and sublethal effects on the parameters weight, mortality and pupal viability and reduced oviposition and can be used in pest management, representing an alternative in the product rotation for the control of the third instar of H. armigera.

“…Para o controle de larvas neonatas de H. zea, inseticidas do grupo dos piretroides (Jacobson et al, 2009) têm sido utilizados. No entanto, os diversos problemas associados ao uso extensivo desses inseticidas, como intoxicações e contaminações, têm levado à busca por métodos de controle que ocasionem menor impacto ao ambiente, como o uso de produtos naturais extraídos de plantas (Perez & Iannacone, 2006).…”

Resumo -O objetivo deste trabalho foi avaliar os efeitos do óleo de mamona sobre a broca-grande do tomateiro, Helicoverpa zea, e sobre o parasitoide de ovos Trichogramma pretiosum. Foi determinada a mortalidade larval da broca, que foi submetida ao óleo de mamona por ingestão e contato às concentrações 0,5, 1,0, 1,5, 2,0, 2,5 e 3,0% (v v -1 ). A ação do óleo de mamona sobre T. pretiosum foi determinada mediante testes de seletividade e suscetibilidade. As maiores mortalidades de larvas foram observadas no tratamento por contato com as menores concentrações (0,5 e 1,0%), enquanto com as concentrações intermediárias (1,5; 2,0 e 2,5%), não houve diferença entre as vias de aplicação. À maior concentração testada (3,0%), o tratamento por ingestão proporcionou mortalidade superior àquela obtida por contato. O número de ovos parasitados por T. pretiosum, no teste de seletividade, foi afetado negativamente pelo óleo de mamona, contudo, os demais parâmetros avaliados quanto à seletividade e à suscetibilidade não foram afetados. O óleo de mamona reduz a sobrevivência de larvas de H. zea tanto por ingestão quanto por contato. Além disso, não prejudica o desenvolvimento de T. pretiosum, desde que as pulverizações sejam realizadas após as liberações do parasitoide.Termos para indexação: Ricinus communis, broca-grande, parasitoide de ovos. Toxicity of Castor bean oil on Helicoverpa zea and Trichogramma pretiosumAbstract -The objective of this work was to evaluate the effects of castor bean oil on the tomato fruitworm, Helicoverpa zea, and on the egg parasitoid Trichogramma pretiosum. Mortality of tomato fruitworm was determined for larvae subjected to castor bean oil ingestion and contact at concentrations 0.5, 1.0, 1.5, 2.0, 2.5 e 3.0% (v v -1 ). The castor bean oil action on T. pretiosum was determined by selectivity and susceptibility tests. The greatest larvae mortalities were observed in the treatment by contact with the lowest concentrations (0.5 and 1.0%), while at intermediate concentrations (1.5, 2.0, and 2.5%) there were no differences between the ways of application. At the highest tested concentration of castor bean oil (3.0%), the ingestion treatment caused a higher mortality, in comparison to the treatment by contact. The number of eggs parasitized by T. pretiosum was negatively affected by castor bean oil in the selectivity test; however, other evaluated parameters for selectivity and susceptibility were not affected. Castor bean oil reduces survival of H. zea larvae both by ingestion and contact. In addition, it does not affect the development of T. pretiosum, since sprayings are performed after releasing of the parasitoid.
