Abstract

The Chinese citrus fly, Bactrocera minax (Enderlein) (Diptera: Tephritidae), is the most destructive pest in many citrus orchards of south central China. Methyl eugenol and cuelure, 2 potent male lures that are effective for capturing related species, are believed not to attract this species. Limited knowledge is available about the effectiveness of attractant traps for this pest. A field trial was carried out to determine the efficacy of 8 attractant traps to B. minax. The study was conducted during the adult occurrence season in an orchard of navel orange, Citrus sinensis (L.) Osbeck (Rutaceae), in Zhijiang County, Hunan Province, China, in 2016. To link the efficacy of these attractant traps with the pest population, fruit infestations in the orchard also were investigated. As expected, this study confirmed that methyl eugenol and cuelure were not attractive to B. minax. Green-colored sticky spheres trapped significantly more flies and males than methyl eugenol and cuelure-baited traps. On average, ammonium acetate + putrescine trapped more females than males, but it was not statistically better than any of the other tested attractant traps. Fruit infestation rates by B. minax ranged from 0.7 to 11.1% in the replicates. Judging by the results of trapping and actual field infestation, it appears that trap effectiveness of the 8 attractant traps was low. A more potent attractant trap is needed, especially for early detection of the pest.

 

Resumen

La mosca china de los cítricos, Bactrocera minax (Enderlein) (Diptera: Tephritidae), es la plaga más destructiva en muchos huertos de cítricos del sur de China central. Se cree que el metil eugenol y la cuelure, dos señuelos potentes para los machos son efectivos para capturar especies relacionadas,pero se cree que no atraen a esta especie. Existe conocimiento limitado sobre la efectividad de las trampas atrayentes para esta plaga. Se realizó una prueba de campo para determinar la eficacia de 8 trampas atrayentes para B. minax. El estudio se realizó durante la temporada cuando los adultos estran presentes en un huerto de naranja navel, Citrus sinensis (L.) Osbeck (Rutaceae), en el condado de Zhijiang, Provincia de Hunan, China, en el 2016. Para vincular la eficacia de estas trampas atrayentes con la población de la plaga, también se investigaron las infestaciones del fruto en el huerto. Como se esperaba, este estudio confirmó que el metil eugenol y la cuelure no fueron atractivos para B. minax. Las esferas pegajosas de color verde atraparon significativamente más moscas y machos que el metil eugenol y las trampas con cebo de cuelure. En promedio, el acetato de amonio + putrescina atrapó más hembras que machos, pero no fue estadísticamente mejor que cualquiera de las otras trampas atrayentes probadas. Las tasas de infestación de frutos por B. minax varían entre el 0.7 y 11.1% en las réplicas. A juzgar por los resultados de las trampas y las infestaciones en el campo, parece que la eficacia de las trampas de las 8 trampas atrayentes fue baja. Se necesita una trampa atrayente más potente, especialmente para la detección temprana de la plaga.
