Abstract

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...
