Abstract

Various chemical principle of leaves (total nitrogen, phosphorus, potassium, calcium, magnesium, iron, copper, zinc, silicon, manganese, crude protein, phenol, vitamin C, acidity, lipid, chlorophyll, total sugar reducing and non-reducing sugar and moisture) varied significantly among five varieties of pineapple. Only two (zinc and silicon) showed a positive relationship with population density of Dolichotetranychus floridanus in the varieties Queen (6.80 ppm.), Giant Kew (5.70 ppm.) and Kew (4.50 ppm.).
