摘要

 The yellow mite, Polyphagotarsonemus latus Banks (Acari: Tarsonemidae) population is one of the most destructive pests of jute crop (Corchorus capsularis L.) in Bangladesh. Jute plants of deshi (Corchorus capsularis L) varieties were considered as treatments viz., CVL-1, CVE-3, BJC-7370 and BJC-83. The paired plot treatments (miticide treated and miticide untreated cintrol) were laid out under net house condition. The effect of yellow mite, Polyphagotarsonemus latus Banks, were studied on three stages of jute plants: 60 DAS, 90 DAS and 120 DAS. The higher number of mite stages observed upto 90 DAS then declined afterward upto 120 DAS in var. BJC-7370 among four C. capsularis varieties. A damage index scale (0-5) was to assess yellow mite injury to jute plants. The percent infestation and damage index was also used to relate yellow mite injury to number of leaves, leaf area, fresh leaf weight, dry leaf weight, soluble solids, plant height, base diameter, fibre weight, stick weight, number of flowers per plant, number of pods, pod weight per plant, seed per pod, seed weight and 1000 seed weight of plants infested at three different phenological stages. The yield contributing characters of untreated pots showed significant damage at 60, 90 and 120 DAS in C. capsularis varieties compared to treatment pots. The highest fibre yield losses due to mite infestation was found in the variety BJC-7370 (65.10%) followed by CVE-3 (61.46%), CVL-1 (58.83%) and the lowest was in BJC-83 (52.97%); the highest stick yield losses due to mite infestation was found in the variety BJC-7370 (51.29%) followed by CVE-3 (47.54%), BJC-83 (46.49%) and the lowest was in CVL-1 (44.21%) and the highest seed yield losses due to mite infestation was found in the variety BJC-7370 (38.25%) followed by CVE-3 (31.93%), CVL-1 (29.28%) and the lowest was in BJC-83 (28.89%) for Corchorus capsularis under net house condition. High yellow mite population in the untreated check decreased plant growth and showed significant yield loss in the variety BJC-7370.
