Abstract: Areca catechu L. is one of the most important plantation crop cultivated in Kerala. Recent reports indicate that phytophagous mites could infest the foliage and nuts of areca palm and induce substantial damage, leading to various levels of economic loss. Among the mites, Raoiella indica Hirst, popularly called Red Palm Mite (RPM) has been recognized as a serious pest of areca palm in various localities of India. Various life stages of this mite were found colonizing and feeding on the lower surface of palm leaves, by de-sapping and which in turn would lead to the formation of yellowish speckles and bronzing in later stages and the ultimate drying up of the leaves. Photosynthesis, being a vital process determining the plant vigour and productivity should be addressed with great concern. In the present study, attention has been focused to analyse the feeding impact of the red palm mite, on the photosynthetic machinery of areca palms through the quantitative estimation of chlorophyll ‘a’, ‘b’, ‘total chlorophyll’ pigments and also ‘photosynthetic efficiency’ of mite infested and uninfested leaves. Results of the study revealed that the feeding activity of the mite on the leaves of A.catechu induced drastic reduction in the levels of chlorophyll ‘a’, ‘b’, ‘total chlorophyll’ and ‘photosynthetic efficiency’. The percentage loss in chl ‘a’, chl ‘b’ and ‘total chlorophyll’ were 62.21±0.63, 57.67±0.73 and 59.884±0.375 respectively in RPM infested Areca leaves. RPM infestation varied significantly in photosynthetic parameters such as minimum fluorescence (F0), maximum fluorescence ( Fm), variable fluorescence (Fv), quantum yield of photosynthesis (Fv/Fm), performance index (PI) and the Area which has a negatively impact on photosynthetic efficiency of areca palms. These data obtained from chlorophyll analysis and photosynthetic efficiency were found significant at 0.05level, up on statistical analysis using t-test, thereby establishing the pest status of RPM on A. catcheu.
