Resumo: | The olive leaf moth Palpita forficifera Munroe (Lepidoptera: Crambidae) is a serious pest in Brazilian olive groves, and can cause severe yield losses if not managed properly. Due the scarcity of information and alternatives for management of this species, this study aimed to evaluate the efficacy of insecticides against P. forficifera in laboratory. The insecticides evaluated were spinetoram, lambda cyhalothrin + chlorantraniliprole, chlorantraniliprole, thiamethoxam + lambda cyhalothrin, lufenuron and Bacillus thuringiensis. Leaves of Ligustrum lucidum were immersed for three seconds in the insecticides’ solutions and offered to third instar larvae after drying. For each treatment, five Petry dishes with eight larvae were used. Mortality was recorded at 24, 48 and 72h after larvae exposure. The neurotoxic insecticides spinetoran, lambda cyhalothrin + chlorantraniliprole and thiamethoxam + lambda cyhalothrin caused mortality rates superior to 56% at 24h, while chlorantraniliprole, lufenuron and B. thuringiensis had a slower effect, with gradual increase in mortality from 48h. Lufenuron caused mortality of 63.3% at 72h, below the minimum efficiency of 80% required for pest control. Spinetoran, lambda cyhalothrin + chlorantraniliprole, thiamethoxam + lambda cyhalothrin, chlorantraniliprole and B. thuringiensis showed effectiveness in the control of P. forficifera larvae, with cumulative mortality at 72h ranging from 82.5 to 100%, and are useful options for control of this pest in olive groves. |

Diante da escassez de informações e das opções para controle desta espécie, objetivou-se com este estudo avaliar a eficácia de inseticidas para controle de lagartas de P. forficifera em laboratório. Os inseticidas avaliados foram espinetoram, lambda-cialotrina + clorantraniliprole, clorantraniliprole, tiametoxam + lambda-cialotrina, lufenurom e Bacillus thuringiensis. Folhas de Ligustrum lucidum foram imersas por três segundos nas caldas dos inseticidas e, após secagem, ofertadas a lagartas de terceiro instar. Para cada inseticida utilizaram-se cinco placas com oito lagartas. A mortalidade foi avaliada às 24, 48 e 72 horas após a liberação das lagartas. Os inseticidas neurotóxicos espinetoram, lambda-cialotrina + clorantraniliprole e tiametoxam + lambda-cialotrina causaram mortalidades superiores a 56% em 24h, enquanto clorantraniliprole, lufenurom e B. thuringiensis apresentaram ação mais lenta, com aumento gradual da mortalidade a partir das 48h. Lufenurom apresentou mortalidade de 63,3% às 72h, valor abaixo da eficiência mínima exigida de 80% para controle de uma praga. Já espinetoram, lambda-cialotrina + clorantraniliprole, tiametoxam + lambda-cialotrina, clorantraniliprole e B. thuringiensis são eficazes no controle de lagartas de P. forficifera, com mortalidade acumulada às 72h variando de 82,5 a 100%, e apresentam-se como opções a serem utilizadas no manejo desta praga em olivais.Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina - Epagri2019-10-03info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://publicacoes.epagri.sc.gov.br/rac/article/view/45510.22491/RAC.2019.v32n3.9Agropecuária Catarinense Journal; Vol. 32 No. 3 (2019); 68-72Agropecuária Catarinense; v. 32 n. 3 (2019); 68-722525-60760103-0779reponame:Agropecuária Catarinense (Online)instname:Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina (Epagri)instacron:EPAGRIporhttps://publicacoes.epagri.sc.gov.br/rac/article/view/455/452Copyright (c) 2019 Revista Agropecuária Catarinenseinfo:eu-repo/semantics/openAccessCastilhos, Rodolfo VargasBrugnara, Eduardo Cesar2020-04-28T21:40:08Zoai:ojs.publicacoes.epagri.sc.gov.br:article/455Revistahttps://publicacoes.epagri.sc.gov.br/RAC/indexPUBhttps://publicacoes.epagri.sc.gov.br/index.php/RAC/oaieditoriarac@epagri.sc.gov.br || lamperuch@epagri.sc.gov.br2525-60760103-0779opendoar:2020-04-28T21:40:08Agropecuária Catarinense (Online) - Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina (Epagri)false |
