TLDR
JRO 524 was found to be the most tolerant to mite infestation, whereas JRO 36E and JRO 632 were susceptible in nature and no significant difference was observed between healthy and infested leaves.Abstract:
Effect of yellow mite, Polyphagotarsonemus latus Bank, infestation on the quantitative change of micronutrients, viz, Zn and Cu in the leaves of five olitorius varieties (JRO 524, JRO 7835, JRO 878, JRO 36E and JRO 632) was studied. JRO 524 was found to be the most tolerant to mite infestation, whereas JRO 36E and JRO 632 were susceptible in nature. Healthy leaves of JRO 524 had significantly more (42.39%) Zn than that of JRO 36E. On an average, the infested leaves contained 10% less Zn, while the infested leaves contained 10% more copper than the healthy ones. Varieties significantly differed in Zn and Cu content but no significant difference was observed between healthy and infested leaves. The interactiqn between variety and infestion was not significant in the case of Zn, but was significant for Cu.read more

SSR Markers Linked to Mite (Polyphagotarsonemus latus Banks ) Resistance in Jute (Corchorus olitorius L.)
TL;DR: A genetic linkage map was constructed using these polymorphic primers in one hundred and fifty F 2 populations, derived from a cross between the parents, to select genotypes with the desired resistance allele combination using DNA markers.

Biochemical Effects of Cultivated and Wild Jute Species on Life Stages of the Broad Mite, Polyphagotarsonemus latus (Prostigmata: Tarsonemidae)
TL;DR: Among the 7 species of jute, the cultivated C. olitorius was the most suitable host for broad mites and it is evident that biochemical leaf constituents have an important role in the growth and buildup of mite pests in these crops.
