Resumo: | The use of systemic insecticides in seed treatment is considered safer for non-target organisms compared to other forms of application. For this reason, there is concern about possible effects that contaminated extrafloral nectar may cause on beneficial organisms. (1) Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae) and (2) Chrysoperla externa (Hagen) (Neuroptera: Chrysopidae) were studied in order to evaluate the effect of chlorantraniliprole on the development, when larvae and adults of these predators were exposed to cotton plants grown from seeds treated with this insecticide, as well as to gather information from the main studies carried out with chlorantraniliprole seed treatment for eight natural enemies in three cultures. Chlorantraniliprole did not cause a lethal effect on H. axyridis, but transgenerational negative effects were observed. When larvae were exposed to the contaminated extrafloral nectar there was a reduction in larval and pupal development time, males weight and insect survival of the next generation to that exposed. Ladybugs from adults who came in contact with contaminated extrafloral nectar also had reduced pupal development time, egg viability and survival. The predator C. externa did not present negative transgenerational effects, and only when larvae were exposed to the product, the pupae formed had a minor development period. The other biological characteristics observed were not negatively influenced by the insecticide. Larvae of H. axyridis are attracted to untreated cotton plants compared to cotton seedlings treated with chlorantraniliprole; however, C. externa adults were attracted to cotton plants from treated or untreated seeds. For the predators Lysiphlebus testaceipes (Cresson) (Hymenoptera, Braconidae, Aphidiinae), Coleomegilla maculata (Coleoptera: Coccinelidae), Orius insidiosus (Say) (Hemiptera: Anthocoridae) and C. externa, the insecticide was classified as slightly harmful; However, Chrysoperla carnea (Stephens) (Neuroptera: Chrysopidae), H. axyridis, Hippodamia convergens (Guérin-méneville) (Coleoptera: Coccinellidae) and Podisus nigrispinus (Dallas) (Heteroptera: Pentatomidae) chlorantraniliprole were harmless according to IOBC toxicity classification. |

Entretanto, por estes produtos translocarem no interior das plantas, podem estar presentes em néctar extrafloral que é um importante alimento para os inimigos naturais. Diante disso, os objetivos do presente estudo foram avaliar se o clorantraniliprole causa efeitos negativos no desenvolvimento, reprodução e comportamento de (1) Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae) e (2) Chrysoperla externa (Hagen) (Neuroptera: Chrysopidae) quando larvas e adultos desses predadores foram expostos a plantas de algodão cultivadas a partir de sementes tratadas com este inseticida, bem como reunir informações dos principais estudos realizados em tratamento de sementes com clorantraniliprole para oito inimigos naturais em três culturas. Clorantraniliprole não causou efeito letal sobre H. axyridis, porém foram observados efeitos negativos transgeracionais. Quando larvas foram expostas ao néctar extrafloral contaminado houve redução no tempo de desenvolvimento de larvas e pupas, peso de machos e sobrevivência dos insetos da geração seguinte à exposta. As joaninhas provenientes de adultos que entraram em contato com néctar extrafloral contaminado também tiveram o tempo de desenvolvimento pupal, viabilidade dos ovos e sobrevivência reduzidos. O predador C. externa não apresentou efeitos transgeracionais negativos, sendo que somente quando larvas foram expostas ao produto, as pupas formadas apresentaram período de desenvolvimento menor. As demais características biológicas observadas não sofreram influência negativa do inseticida. Larvas de H. axyridis têm atração por plantas de algodão sem tratamento em comparação com plantas de algodão oriundas de sementes tratadas com clorantraniliprole; entretanto, adultos de C. externa foram atraídos por plantas de algodão provenientes de sementes tratadas ou não de forma semelhante. Para os predadores Lysiphlebus testaceipes (Cresson) (Hymenoptera, Braconidae, Aphidiinae), Coleomegilla maculata (DeGeer) (Coleoptera: Coccinelidae), Orius insidiosus (SAY, 1832) (Hemiptera: Anthocoridae) e C. externa, o inseticida foi classificado como levemente prejudicial; porém, Chrysoperla carnea (Stephens) (Neuroptera: Chrysopidae), H. axyridis, Hippodamia convergens (Guérin-méneville) (Coleoptera: Coccinellidae) e Podisus nigrispinus (Dallas) (Heteroptera: Pentatomidae) clorantraniliprole foi inócuo, segundo classificação de toxicidade da IOBC.Universidade Federal de LavrasPrograma de Pós-Graduação em EntomologiaUFLAbrasilDepartamento de EntomologiaCarvalho, Geraldo AndradeGontijo, Pablo da CostaYamamoto, Pedro TakaoSchneider, Marcela InésRocha, Luiz Carlos DiasMoscardini, Valéria FonsecaOliveira, Rodrigo Lopes de2018-04-03T12:49:48Z2018-04-03T12:49:48Z2018-04-022018-02-23info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisapplication/pdfOLIVEIRA, R.
