Alternative control of the coconut mite, Aceria guerreronis

The coconut is one of the most important crops in the northeast of Brazil. However, it is affected by several pests. The coconut eriophyid mite Aceria guerreronis, Keifer, (1965), is one of these pests. It is responsible for yield losses. In order to determine the efficiency of Acanat, an experiment...

spelling Alternative control of the coconut mite, Aceria guerreronisControle alternativo do ácaro da necrose do coqueiroNeem, Citroneal, Thymol, Aceria guerreronis, Cocus nucifera. The coconut is one of the most important crops in the northeast of Brazil. However, it is affected by several pests. The coconut eriophyid mite Aceria guerreronis, Keifer, (1965), is one of these pests. It is responsible for yield losses. In order to determine the efficiency of Acanat, an experiment was carried out in a field to control the coconut mite. A randomized block design was used, with four treatments (0; 5; 10; 15 ml.L-1) and four replications. The following parameters were evaluated: Damage level, number of living mites and weight of fruits. The smallest concentration of Acanat (5 ml.L-1) reduced the damage caused by mites in 18.9%, the intermediate (10 ml.L-1) in 28.34% and the highest concentration (15 ml.L-1) reduced in 32.43%. Decreasing of living mites in 84.12%, 95.69% and 96.78% was obtained with the same concentrations. The weight of treated coconut fruits with concentrations of 5 ml.L-1, 10 ml.L-1 and 15 ml.L-1 was higher than untreated fruits in 21.87, 43.75 and 65.62%, respectively.O coqueiro é uma das culturas de maior importância para a região nordeste como geradora de emprego e renda para a população local. No entanto, tem seu desenvolvimento e produção afetados por várias pragas, entre as quais, o ácaro da necrose Aceria guerreronis, Keifer, (1965), responsável por grande redução na produção. Para determinar a eficiência do acaricida Acanat no controle desse ácaro conduziu-se um experimento de campo com delineamento em blocos ao acaso com 4 tratamentos (0; 5; 10 e 15 ml.L-1) e 4 repetições, avaliando-se os parâmetros: nível de ataque, número de ácaros vivos e o peso dos frutos. A menor concentração (5 ml.L-1) reduziu o dano causado pelo ácaro em 18,9%, a intermediária (10 ml.L-1) em 28,34% e a maior concentração (15 ml.L-1) reduziu em 32,43%. Constatou-se uma diminuição de ácaros vivos em 84,12%, 95,69% e 96,78% nas mesmas concentrações. O peso dos frutos tratados com as concentrações de 5,0; 10 e 15 ml.L-1 foi superior aos dos não tratados em 21,87; 43,75 e 65,62%, respectivamente.Revista Ciência Agronômica2008-11-18info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://periodicos.ufc.br/revistacienciaagronomica/article/view/83720Revista Ciência Agronômica; v. 37 n. 3 (2006)1806-66900045-6888reponame:Revista ciência agronômica (Online)instname:Universidade Federal do Ceará (UFC)instacron:UFCenghttp://periodicos.ufc.br/revistacienciaagronomica/article/view/83720/227872info:eu-repo/semantics/openAccessFreitas, JoséInnecco, RenatoMendes, AntônioGonçalves, Manoel2023-02-28T06:37:49Zoai:periodicos.ufc:article/83720Revistahttps://periodicos.ufc.br/revistacienciaagronomicaPUBhttps://periodicos.ufc.br/revistacienciaagronomica/oai||alekdutra@ufc.br|| ccarev@ufc.br1806-66900045-6888opendoar:2023-02-28T06:37:49Revista ciência agronômica (Online) - Universidade Federal do Ceará (UFC)false
