Resumo: The melon (Cucumis melo L.) is one of the main cucurbits grown in northeastern Brazil. Among the main obstacles to the production of melon, the leafminer Liriomyza sativae (Diptera: Agromyzidae) stands out as one of the main pests. Since the discovery of natural enemies Opius scabriventris (Hymenoptera: Braconidae) and Neochrysocharis sp. (Hymenoptera: Eulophidae) in melon production areas RN and CE, increased the prospects of the use of biological control in this region. However, information on the preferred instar and competition among parasitoids Opius scabriventris and Neochrysocharis sp. still are scarce. Furthermore, the conservation of these parasitoids in agrosystem is of fundamental importance to the MIP, therefore, it is necessary to know the action of plant protection products on O. scabriventris and Neochrysocharis sp. Therefore, the objective of this study was to define the preferred instar O. scabriventris and Neochrysocharis sp., Evaluate the competition between these two species and the toxicity of insecticides used in melon crop on these two parasitoids in laboratory conditions. To determine the preferred instar were exposed leafminer larvae first, second and third instar for the two species of parasitoids. The competition studies were to assess the simultaneous parasitism O. scabriventris x Neochrysocharis sp. in proportions of 1x1, 2x1, 1x2 for the second and third larval instar L. sativae. The toxicity of insecticides to parasitoids were evaluated in bioassays through contact of parasitoids with freshly contaminated surface. The treatments were: abamectin, clorantraniliprole, cyromazine, espinetoram, spinosad and distilled water (control). Later, with the parasitoids that survived the tests of toxicity were evaluated sublethal effects of pesticides that caused lower mortality on the parasitism capacity. Regarding prefered instar tests, O. scabriventris preferably parasitized second instar larvae, while Neochrysocharis sp. preferred third instar larvae. Regarding competition assays, it was found that parasitoids O. scabriventris and Neochrysocharis sp. competed for larvae second and third instar L. sativae. Regarding toxicity tests, the abamectin, espinetoram and spinosad were the most toxic to the parasitoid O. scabriventris and Neochrysocharis sp. The clorantraniliprole and cyromazine insecticide caused reduction in parasitism capacity of O. scabriventris

Dentre os principais entraves à produção do meloeiro, a mosca minadora Liriomyza sativae (Diptera: Agromyzidae) se destaca como uma das principais pragas. Desde a constatação dos inimigos naturais Opius scabriventris (Hymenoptera: Braconidae) e Neochrysocharis sp. (Hymenoptera: Eulophidae) em áreas de produção de melão do RN e CE, cresceram as perspectivas da utilização do controle biológico nessa região. No entanto, informações sobre o instar preferencial e a competição entre os parasitoides Opius scabriventris e Neochrysocharis sp. são escassas. Além disso, a conservação desses parasitoides no agrossistema é de fundamental importância para o MIP, sendo assim, é necessário conhecer a ação dos produtos fitossanitários sobre O. scabriventris e Neochrysocharis sp. Portanto, o objetivo do presente trabalho foi definir o instar preferencial de O. scabriventris e Neochrysocharis sp., avaliar a competição entre essas duas espécies e a toxidade de inseticidas utilizados na cultura do meloeiro sobre esses dois parasitoides em condições de laboratório. Para determinar o instar preferencial, foram expostas larvas de mosca minadora de primeiro, segundo e terceiro instar para as duas espécies de parasitoides. Os estudos de competição consistiram em avaliar o parasitismo simultâneo de O. scabriventris x Neochrysocharis sp. nas proporções de 1x1, 2x1, 1x2 para larvas de segundo e terceiro instar de L. sativae. A toxicidade dos inseticidas aos parasitoides foram avaliados em ensaios biológicos por meio do contato dos parasitoides com superfície recém-contaminada. Os tratamentos foram: abamectina, clorantraniliprole, ciromazina, espinetoram, espinosade e água destilada (Testemunha). Posteriormente, com os parasitoides que sobreviveram aos ensaios de toxicidade, foram avaliados os efeitos subletais dos inseticidas que ocasionaram menor mortalidade sobre a capacidade de parasitismo. Quanto aos ensaios de ínstar preferencial, O. scabriventris parasitou preferencialmente larvas de segundo instar, enquanto que Neochrysocharis sp. preferiu larvas de terceiro instar. Em relação aos ensaios de competição, verificou-se que os parasitoides O. scabriventris e Neochrysocharis sp. competiram por larvas segundo e terceiro instar de L. sativae. Em relação aos ensaios de toxicidade, os inseticidas abamectina, espinetoram e espinosade foram os mais tóxicos aos parasitoides O. scabriventris e Neochrysocharis sp. Os inseticidas clorantraniliprole e ciromazina ocasionaram redução na capacidade de parasitismo de O. scabriventrisCoordenação de Aperfeiçoamento de Pessoal de Nível SuperiorUniversidade Federal Rural do Semi-ÁridoBRCentro de Ciências Agrárias - CCAUFERSAPrograma de Pós-Graduação em FitotecniaSales Junior, RuiCPF:87634325449http://lattes.cnpq.br/8366676949063957Araujo, Elton Lucio deCPF:67325327404http://lattes.cnpq.br/1455726768450040Godoy, Maurício Sekiguchi deCPF:21511653884http://lattes.cnpq.br/2559789369754261Silva, Raimundo Ivan RemígioCPF:12239690372http://lattes.cnpq.br/0570770462560636Silva, Francisco Edivino Lopes da2016-08-12T19:15:36Z2016-05-092016-02-29info:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfSILVA, Francisco Edivino Lopes da.
