Abstract
We studied the life cycle of the broad mite, Polyphagotarsonemus latus (Banks) (Prostigmata: Tarsonemidae), on 2 cultivated jute species (Corchorus olitorius L. and Corchorus capsularis L.; Malvales: Malvaceae) and 5 wild species (Corchorus aestuans L., Corchorus pseudo-olitorius Islam & Zaid, Corchorus fascicularis Lamarck, Corchorus tridens L., and Corchorus trilocularis L.) under laboratory conditions. Results showed that the egg incubation period, larval and nymphal durations, and adult male and female longevities of P. latus varied significantly on different jute species. The larval period (mean ± SD) was significantly shorter (57.00 ± 2.07 h) on C. olitorius than on C. fascicularis, C. aestuans, and C. tridens (68.00 ± 1.58 to 72.00 ± 1.30 h). The phenol content was greatest in C. trilocularis (61.92 ± 1.91 μg/g), and it was 16.26 ± 1.34 μg/g and 20.45 ± 1.43 μg/g in C. olitorius and C. capsularis, respectively. The polyphenol oxidase content was smallest in C. capsularis (0.99 ± 0.10 μg/mL... Resumen Se estudió la biología del ácaro ancho, Polyphagotarsonemus latus (Banks) (Prostigmata: Tarsonemidae) en 2 especies cultivadas de yute (Corchorus olitorius L. y C. capsularis L.; Malvales: Malvaceae) y 5 especies silvestres (C. aestuans, C. pseudo-olitorius, C. fascicularis, C. tridens, C. trilocularis) en condiciones de laboratorio. El estudio reveló que el período de incubación de huevos de P. latus sobre diferentes especies varió de 45.0 h en C. capsularis a 51.0 h en C. olitorius en comparación con 46.0 h y 53.0 h en C. trilocularis y C. fascicularis, respectivamente. El período larval total fue significativamente menor en C. olitorius (57.0 h.) En comparación con C. pseudo-olitorius (59.0 a 72.0 h). La longevidad de los ácaros adultos en las especies cultivadas fue menor que en las especies silvestres, excepto en C. fascicularis. El contenido de fenoles mas alto fue en C. trilocularis (61.92 mg/g) y fue 16.26 mg/g y 20.45 mg/g en C. olitorius y C. capsularis, respectivamente. La actividad del...Keywords
