Resumo: | The two-spotted spider mite, Tetranychus urticae Koch (Acari: Tetranychidae), is one important pest of cotton crop due to reductions in cotton yield and fiber quality. Thus, this work evaluated the toxicity of the synthetic acaricide spiromesifen and natural products on T. urticae and the compatibility with the predatory mite Phytoseiulus macropilis (Banks) (Acari: Phytoseiidae). Spiromesifen and the natural products Azadirachtin A/B, Azadirachtin 1%, Jatropha curcas L. and Ricinus communis L. oils were used at different concentrations; the leaf dipping method was employed. The mortality of T. urticae females and eggs was evaluated 48 and 96 h after treatment to calculate the lethal concentrations. The effect on P. macropilis was studied using the LC50s obtained to T. urticae. All acaricides tested were effective in controlling females and eggs of T. urticae. However, according to the LC50s and LC90s calculated, spiromesifen was the most toxic acaricide to females and J. curcas oil presented the higher toxicity to eggs. Spiromesifen, J. curcas oil and Azadiractina 1% caused side effects on P. macropilis. However, only espiromesifeno was classified as harmful to the predator, whereas Azadirachtin A/B and R. communis oil were slightly harmful. R. communis and Azadirachtin A/B were effective in controlling the two-spotted spider mite and promising for the management of this pest in cotton considering their low toxicity to the predator. |

Assim, este trabalho se propôs a avaliar a toxicidade do acaricida sintético espiromesifeno e produtos naturais para T. urticae e a compatibilidade com o seu predador Phytoseiulus macropilis (Banks) (Acari: Phytoseiidae). Espiromesifeno e os naturais Azadiractina A/B, Azadiractina 1%, Jatropha curcas L. e Ricinus communis L. foram utilizados em diferentes concentrações; usou-se a técnica de imersão de discos de folha de algodão nas caldas dos produtos. As mortalidades de fêmeas e ovos de T. urticae foram avaliadas após 48 e 96 h da aplicação, respectivamente, visando à obtenção das concentrações letais. Estudou-se o efeito sobre P. macropilis, com base nas CL50s obtidas para T. urticae. Todos os acaricidas testados foram eficientes no controle de fêmeas e ovos de T. urticae. Entretanto, de acordo com as CL50s e CL90s, espiromesifeno foi o mais tóxico para fêmeas e o óleo de J. curcas apresentou a maior toxicidade para ovos. Espiromesifeno, J. curcas e Azadiractina 1% causaram efeito adverso para P. macropilis. No entanto, espiromesifeno foi o único classificado como nocivo para o predador, enquanto Azadiractina A/B e R. communis foram levemente nocivos. R. communis e Azadiractina A/B foram eficientes no controle do ácaro rajado e promissores para o manejo desta praga no agroecossistema algodoeiro, considerando sua baixa toxicidade para o predador.
