“…Entretanto, o controle químico é considerado indispensável na cultura da soja. Os produtos mais adequados para serem utilizados no MIP são aqueles que combinam controle eficiente da praga com o menor impacto sobre a atividade dos inimigos naturais, sendo essa integração de produtos químicos com o controle biológico, na maioria dos casos, crucial para o sucesso do agronegócio (BUENO & FREITAS, 2004). Inseticidas e acaricidas seletivos, bem como herbicidas, fungicidas e outros produtos químicos e biológicos, devem ser preferidos para que os inimigos naturais sejam preservados (BUENO et al, 2008a).…”

“…Apesar da mortalidade embrionária signifi cativa causada por triclorfom para ovos de C. externa oriundas de Vacaria, os resultados obtidos evidenciam tolerância da fase de ovo da espécie a pesticidas, assim como observado por outros autores (Carvalho et al 2002, Godoy et al 2004, Bueno & Freitas 2004, Silva 2004, Ferreira et al 2005.…”

“…Essa é uma característica importante e que deve ser considerada na escolha da população do inimigo natural a ser utilizada em programas de controle biológico aplicado, notadamente em pomares de macieira conduzidos sob o sistema de PI no Sul do Brasil. Baseando-se, ainda, nesses resultados, sugere-se que a avaliação da oviposição para C. externa seja realizada por um período maior, em testes de seletividade, o que já tem sido observado na literatura científi ca, porém, ainda de forma escassa (Bueno & Freitas 2004).…”

-The goal of this work was to evaluate the effects of the pesticides abamectin, carbaryl, fenitrothion, methidathion, sulphur and trichlorfon on eggs of two Chrysoperla externa (Hagen) populations, as well as on the subsequent developmental stages and reproduction capacity of this green lacewing. Pesticide exposure and distilled water (control) were accomplished using a Potter's tower. None of the evaluated pesticides affected the egg viability of the C. externa populations studied, but abamectin and carbaryl caused signifi cant mortality of other developmental stages of the predator. Sex ratio and reproduction capacity of females originated from treated eggs were unaffected. However, egg viability of C. externa from Bento Gonçalves, RS, Brazil, was reduced by sulphur. Considering to the total effect (E) of each pesticide, trichlorfon, fenitrothion, methidathion and abamectin were harmless to both C. externa populations (Bento Gonçalves and Vacaria), when applied on eggs, whereas carbaryl was slightly harmful. On the other hand, the fungicide sulphur was slightly harmful to C. externa from Bento Gonçalves, but harmless to those from Vacaria.

“…Este insecto es empleado en MIP (Manejo Integrado de Plagas), debido a su fácil crianza en cautiverio y potencial de adaptación en diversos ambientes (Núñez, 1988). Incluso esta especie ha mostrado cierta resistencia a la aplicación de numerosos insecticidas (Bueno & Freitas, 2004;Moura et al, 2012;De Fátima et al, 2013), incluyendo a los de origen botánico (Iannacone & Lamas, 2002).…”

In Integrated Pest Management (IPM), it is sought that the biocides used are to a greater extent selective with the natural enemies present in the field. Within this framework, Ruta graveolens "rue" (Rutaceae) is used for pest control because of its diverse natural properties. This study aimed to evaluate the sensitivity of two biocontrollers Chrysoperla externa and Chrysoperla carnea (Neuroptera: Chrysopidae) compared to aqueous extract of R. graveolens. They were exposed in tests of static acute toxicity (residual contact), larvae of I instar of both species of -1 lacewings to three doses of aqueous extract (2, 5 and 10g·100mL ) of leaves of rue, in flowering stage of the plant. The results of larval mortality at 24 and 48h of exposure were recorded. The correction of mortality was made by Schneider-Orellis's formula. To calculate the values of NOEC and LOEC were used statistical method ANOVA and Duncan post hoc test (p≤0.05). The results show that both species had similar responses to extract in both periods of exposure, no significant differences between the percentages of mortality in the three concentrations and controls. NOEC values were 10g·100mL and LOEC> 10g·100mL , which could suggest the compatibility of these two biocontrollers with the application of aqueous extracts of R. graveolens, and therefore potential use in IPM.
