Summary: | One of the most common predatory species in coffee agrosystems is Chrysoperla externa (Hagen, 1861) (Neuroptera: Chrysopidae). Its maintenance, however, depends on the application of non-toxic pesticides. Thus, bioassays were carried out in laboratory conditions to evaluate the selectivity of the acaricides spirodiclofen (Envidor – 0.12 g a.i.L-1), fenpropathrin (Meothrin 300 – 0.15 and 0.30 g a.i.L-1), sulphur (Thiovit Sandoz – 4.0 and 8.0 g a.i.L-1 and, abamectin (Vertimec 18 CE – 0.0067 and 0.0225 g a.i.L-1) on this predator’s eggs. The C. externa eggs were directly sprayed using a Potter’s tower. The eggs were then placed in glass tubes and kept in a climatic chamber at 25±2oC, RH of 70±10% and 12 hour photophase. The pesticides were classified according to the recommendations of the IOBC. Fenpropathrin (0.30 g a.i.L-1) was harmful and fenpropathrin (0.15 g a.i.L-1) was moderately harmful to the green lacewing. The products spirodiclophen, sulphur and abamectin were moderately harmful to the predator. New assays in greenhouse and field conditions should be carried out to verify the toxicity of these compounds. |

Dessa forma, foram realizados bioensaios em laboratório para avaliar a seletividade dos acaricidas espirodiclofeno (Envidor – 0,12 g i.a.L-1), fenpropatrina (Meothrin 300 – 0,15 e 0,30 g i.a.L-1), enxofre (Thiovit Sandoz – 4,0 e 8,0 g i.a.L-1) e abamectina (Vertimec 18 EC – 0,0067 e 0,0225 g i.a.L-1) para ovos desse predador. Após a pulverização dos produtos em torre de Potter, os ovos foram colocados em tubos de vidro e mantidos em câmara climática a 25±2oC, UR de 70±10% e fotofase de 12 horas. Os compostos foram enquadrados em classes de toxicidade de acordo com o seu efeito total (E), seguindo recomendações da IOBC. Fenpropatrina (0,3 g i.a.L-1) foi nocivo e fenpropatrina (0,15 g i.a.L-1) foi moderadamente nocivo ao crisopídeo. Os produtos espirodiclofeno, enxofre e abamectina foram moderadamente nocivos ao predador. Novos testes em condições de casa de vegetação e campo devem ser realizados para comprovação ou não da toxicidade desses compostos.Editora UFLA2010-09-10info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfhttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/267Coffee Science - ISSN 1984-3909; Vol. 5 No. 1 (2010); 10-16Coffee Science; Vol. 5 Núm. 1 (2010); 10-16Coffee Science; v. 5 n. 1 (2010); 10-161984-3909reponame:Coffee Science (Online)instname:Universidade Federal de Lavras (UFLA)instacron:UFLAengporhttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/267/247https://coffeescience.ufla.br/index.php/Coffeescience/article/view/267/pdfCopyright (c) 2010 Coffee Science - ISSN 1984-3909https://creativecommons.org/info:eu-repo/semantics/openAccessVilela, MichelleCarvalho, Geraldo AndradeCarvalho, César FreireVilas Boas, Matheus Alvarenga2013-02-24T13:19:56Zoai:coffeescience.ufla.br:article/267Revistahttps://coffeescience.ufla.br/index.php/CoffeesciencePUBhttps://coffeescience.ufla.br/index.php/Coffeescience/oaicoffeescience@dag.ufla.br||coffeescience@dag.ufla.br|| alvaro-cozadi@hotmail.com1984-39091809-6875opendoar:2013-02-24T13:19:56Coffee Science (Online) - Universidade Federal de Lavras (UFLA)false |
