Biochemical aspects of interaction between jasmine and blister mite, Aceria jasmini Chan

Abstract

The Jasmine blister mite, Aceria jasmini Chan. is a serious eriophyid mite infesting jasmine commercially grown in many parts of South India. Due to feeding by this mite results in formation of blister like erineal patches on the jasmine leaves. Irregular patches of cottony white erineal mats seen both on adaxial and abaxial surface of the leaves supports hundred of white coloured worm-like mites. Biochemical investigations carried out in the susceptible Long and Pointed Budded variety revealed that there was nonsignificant increase in moisture content, decrease in chlorophyll, total sugars, reducing sugars, significant increase in total free amino acids, phenols, crude protein content and peroxidase activity. Among the nutrients tested, nitrogen, phosphorus and potassium contents increased, while non-significant decrease in calcium and magnesium, whereas significant decrease in iron, manganese, copper and zinc were noticed due to mite feeding.How to view point the article : Vishnupriya, R., Umapathy, G., Ramaraju, K., Malarvizhi, P. and Manivanan, V.

Screening of advanced sugarcane genotypes against rust mite

“…In the present study, the results showed phenolic compounds constitute one of the major defensive mechanisms in host plants against mite attack which were on par with the results noticed by Mitra et al (2015). The present findings were in close agreement with the earlier observations made by Vishnupriya et al (2016) who reported total sugar and reducing sugar had positive influence and phenol content had negative influence on the eriophyid mite. Allah et al (2010) also noticed that an increase in total phenol content likely suppressed mite infestation, whereas increase of total sugar may have a phagostimulatory effect on spider mite, Tetranychus urticae on strawberry plants.…”
