Resumo: This research evaluated the effects of two products based on Bacillus thuringiensis in the mortality rate of first and third instar caterpillars of Spodoptera eridania, in laboratory conditions, at 25±2°C, relative humidity 70±5%, and photoperiod of 12 hours. The treatments were B. thuringiensis kurstaki (Dipel SC), at 500 mL.ha-1, 750 mL.ha-1, and 1000 mL.ha-1; and B. thuringiensis aizawai (XenTari) at 200 g.ha-1, 400 g.ha-1, and 600 g.ha-1, both in a 200 L.ha-1 spray solution, using distilled water as control. The mortality rate was evaluated at 3, 6, 12, 18, 24, 36, 48, 60, 72, and 84 hours after infestation. After 84 hours, the treatments with B. thuringiensis reached 80% of mortality on caterpillars of the first instar. In the same period, the third instar caterpillar mortality rate was 100%.   KEY-WORDS: Biological control; Dipel; XenTari.

O objetivo do presente estudo foi avaliar o efeito de produtos à base de Bacillus thuringiensis na mortalidade de lagartas de Spodoptera eridania, primeiro e terceiro ínstares, em condições de laboratório, a 25±2°C, umidade relativa 70±5% e fotoperíodo de 12/12 horas. Os tratamentos foram constituídos de B. thuringiensis kurstaki (Dipel SC), nas dosagens de 500 mL.ha-1, 750 mL.ha-1 e 1000 mL.ha-1; B. thuringiensis aizawai (XenTari), nas dosagens de 200 g.ha-1, 400 g.ha-1 e 600 g.ha-1, com volume de calda de 200 L.ha-1; e testemunha, com água destilada. A mortalidade das lagartas de terceiro ínstar ocorreu mais rapidamente, em relação às lagartas de primeiro ínstar. Após 84 horas, os tratamentos com B. thuringiensis proporcionaram mortalidade acima de 80%, em lagartas de primeiro ínstar, e, para as lagartas de terceiro ínstar, 100% de mortalidade.   PALAVRAS-CHAVE: Controle biológico; Dipel; XenTari.Escola de Agronomia - Universidade Federal de Goiás2009-06-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresapplication/pdfhttps://revistas.ufg.br/pat/article/view/3865Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 39, n. 2, Apr./Jun. 2009; 140-143Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 39, n. 2, abr./jun. 2009; 140-143Pesquisa Agropecuária Tropical; v. 39, n. 2, abr./jun. 2009; 140-1431983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/pat/article/view/3865/4779Pereira, Jaqueline MagalhãesSeii, Alexander HayakawaOliveira, Marcos FernandesBrustolin, CarlosFernandes, Paulo Marçalinfo:eu-repo/semantics/openAccess2009-06-24T21:50:46Zoai:ojs.revistas.ufg.br:article/3865Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:55:36.300805Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true
