| description | The Asian citrus psyllid Diaphorina citri is the insect vector of the disease known as huanglongbing (HLB), which is the most devastating disease of citrus crops in the world. The Asian citrus psyllid was officially reported in Colombia in 2007, and a national phytosanitary emergency was declared because of the presence of HLB in 2015. Two different experiments were carried out in two locations (Apulo and Jerusalén, Department of Cundinamarca) in Colombia to evaluate the effectiveness of neonicotinoid (clothianidin, imidacloprid and thiamethoxan) and pyrethroid applications (bifenthrin, deltamethrin and lambda cyhalothrin) on the control of D. citri populations (adults, nymphs and eggs) in ‘Tahiti’ lime trees established under tropical dry forest conditions. In the first experiment, trees were foliarly treated as follows: (1) untreated trees; (2) trees treated with 100 g ha-1 of imidacloprid; (3) trees treated with 60 g ha-1 of bifenthrin; (4) trees treated with 12.5 g ha-1 of deltamethrin and (5) trees treated with a co-formulation of 70 g ha-1 of a neonicotinoid (thiametoxan) and 53 g ha-1 of a pyrethroid (lambda cyhalothrin). In the second experiment, trees were treated with 100 g ha-1 of clothianidin. Foliar insecticide applications were carried out at 0 and 4 weeks after the initiation of treatments (WAT). In the first trial, the control presented a mean number of individuals per flush of ≈1.14, whereas the trees treated with neoinicotinoids and pyrethroids showed 50% fewer individuals (0.53-0.61). For the population of immatures, the number of nymphs was 2.25 nymphs per flush in the control, as compared to 0.82-1.22 individuals observed in the treatments with insecticides. The mean number of eggs was also between 80-100% higher in the control trees (2.37 individuals), as compared to the treated trees (1.14-1.78). In the second trial, the use of clothianidin showed a higher control of eggs. The results suggest that the rotation of neonicotinoids with pyrethroids can be a tool to reduce populations and delay resistance processes in D. citri in citrus trees established under tropical dry forest conditions in Colombia. |

El psílido asiático de los cítricos Diaphorina citri es el insecto vector de la enfermedad conocida como huanglonbing (HLB), la cual es la enfermedad más devastadora de estos cultivos en el mundo. El psílido asiático de los cítricos fue reportado oficialmente en Colombia en 2007 y se declaró la emergencia nacional fitosanitaria por HLB en 2015. Con el objetivo de estudiar estrategias de manejo del insecto vector, se llevaron a cabo dos experimentos diferentes en dos localidades (Apulo y Jerusalén, Departamento de Cundinamarca) en Colombia, en los que la efectividad de aplicaciones de neonicotinoides (clothianidin, imidacloprid y thiametoxan) y piretroides (bifentrina, deltametrina y lambdacialotrina) fue evaluada sobre poblaciones de D. citri (adultos, ninfas y huevos) en árboles de lima ‘Tahití’ establecidos en condiciones de bosque seco tropical. En el primer experimento, los árboles fueron tratados foliarmente de la siguiente manera: (1) árboles sin tratar; (2) árboles tratados con imidacloprid a una dosis 100 g ha-1 i.a; (3) árboles tratados con bifentrina a una dosis de 60 g ha-1 i.a; (4) árboles tratados con deltametrina a 12,5 g ha-1 i.a y (5) una coformulación de thiametoxan y lambda-cyalothrina a una dosis de 70 g ha-1 i.a. El segundo experimento consistió en árboles tratados con clothianidin a 100 g ha-1 i.a. Las aplicaciones foliares de los insecticidas fueron desarrolladas a las 0 y 4 semanas de iniciados los tratamientos (SIT). En el primer ensayo, el control presentó ≈1,14 individuos promedio por brote, mientras los árboles tratados con neoinicotinoides y piretroides mostraron un 50% menos de individuos (0,53-0,61). Con respecto a la población de inmaduros, el número de ninfas promedio fue 2,25 ninfas por brote en el control comparado a los 0,82-1,22 individuos observados en los tratamientos con insecticidas. El número de huevos promedio también fue entre un 80-100% mayor en árboles control (2,37 individuos) en comparación a árboles tratados (1,14-1,78). Con respecto al segundo ensayo, el uso de clothianidin presentó un mayor control de huevos. Los resultados obtenidos permiten sugerir que la rotación de neonicotinoides con piretroides puede ser una herramienta para reducir las poblaciones del psílido asiático de los cítricos y retrasar procesos de resistencia del vector en cultivos de cítricos establecidos en condiciones de bosque seco tropical en Colombia.
