Physiochemical Properties of Different Mango Fruit Varieties in Relation to Incidence of Mango Fruit Borer Autocharis albizonalis

Abstrakt

A study was conducted in several mango-producing areas in the districts of Malda, Murshidabad, Nadia and Midnapur in West Bengal during the month of April to June, 2013, to observe the infestation of fruit borer Autocharis albizonalis in eight folk varieties of mango (Mangifera indica L). Frequent observations on incidence of fruit borers showed that the larvae of fruit borer complete their larval stage within the fruit and damage the grown-up fruit during this period. The borer caused substantial damage when the fruits were medium- to full-grown size. During the observation, the physiochemical analysis of the mango varieties mentioned, were also analyzed in the laboratory. From the study, it is found that different physiochemical parameters like TSS, total sugar, reducing sugar and acidity of different mango varieties are changed throughout the developmental period of a mango fruit. From the study, it was found that the average infestation of fruit borer in the folk varieties is continuously higher after fruit set. It was also analyzed that the susceptibility of the fruit borer attack increases with the decrease of acid content of the mango fruit. Therefore, it is revealed that the fruit borer attack is in peak when the acid content of the fruit is at low level.  Keywords: Mango, folk varieties, fruit borer, titrable acidity, phunia Cite this Article Tirthankar Dalui, Subrata Debnath, Kalyan Chakraborti.
