The demand for the reduction of agrochemicals and the search for sustainable production processes is growing. The use of natural products such as metabolites from microorganisms has shown potential to activate defense mechanisms of plants against pathogens, however, this effect is still little explored for the management of insect pests. The objective of the present work is to evaluate the potential of the metabolite of microorganisms, based on glutamic acid (Vorax®) regarding the activation of defense mechanisms of the plant and its relationship with the preference of oviposition of whitefly.

After 48 hours of metabolite application, whitefly adults were exposed to the plants and had free choice, being kept up to 96 hours for oviposition. After this period, oviposition and adult preference were evaluated at 144 and 194 hours after 20 days.

A mosca branca (Bemisia tabaci) é um dos principais insetos causadores de danos na cultura da soja, sendo na maioria das vezes o seu controle realizado com inseticidas. É crescente a demanda pela redução de agroquímicos e pela busca de processos produtivos sustentáveis. O uso de produtos naturais como metabólitos de microrganismos vem demonstrando potencial de ativar mecanismos de defesa de plantas a patógenos, no entanto, tal efeito ainda é pouco explorado para o manejo de insetos pragas. Nesse sentido o objetivo do presente trabalho, é avaliar o potencial do metabólito de microrganismos, a base de ácido glutâmico (Vorax®) quanto a ativação de mecanismos de defesa da planta e sua relação com a preferência de oviposição de mosca branca. O trabalho foi desenvolvido em casa de vegetação e as análises bioquímicas no laboratório de controle biológico da Universidade Tecnológica Federal do Paraná, Campus de Dois Vizinhos. Plantas de soja, foram conduzidas em vasos até o estádio fenológico V6, então aplicado os tratamentos, sendo o metabólito de microorganismo (40ml/100l). Após 48 horas da aplicação do metabólito, adultos de moscas brancas foram expostas as plantas e tiveram livre escolha, sendo mantidas até 96 horas para a oviposição. Após esse período foram avaliadas, com 144 e 194 horas as oviposições e a preferência de adultos após 20 dias. Materiais vegetais foram colhidos, durante todo o experimento nos intervalos de zero, 48, 96, 144 e 192 horas para avaliação de compostos fenólicos e taninos totais. A aplicação do biofertilizante a base de metabólito de microrganismos (Vorax®) ativou rotas metabólicas de defesa vegetal, aumentando os níveis de compostos fenólicos e taninos, e tornou as plantas tratadas com menor preferência dos insetos adultos. 2022-08-15T18:46:00Z 2022-08-15T18:46:00Z 2021-05-07 bachelorThesis SCHMIELESKI, Alessandro Pedro.

The whitefly (Bemisia tabaci) is one of the main insects causing damage to the soybean crop, and most of the time its control is carried out with insecticides. The demand for the reduction of agrochemicals and the search for sustainable production processes is growing.

The objective of the present work is to evaluate the potential of the metabolite of microorganisms, based on glutamic acid (Vorax®) regarding the activation of defense mechanisms of the plant and its relationship with the preference of oviposition of whitefly.
