| Summary: | Phyllocoptruta oleivora (Ashmead) (Acari:Phyllocoptidae) is a serious pest of citrus in most humid regions of the
world. This pest can cause losses in the yield and quality of fruit. In this study, the effect of the fruit quality traits of
P. oleivora was inspected under the Adana ecological condition. For this reason, infested and non-infested fruit
with P. oleivora was collected from Valencia orange trees. The collected fruits were classified according to presence and absence of damage of P. oleivora. The fruits were separated into four categories: 1. Normal, 2: Soft bronze, 3. Bronze and 4. Wide bronze. The classified fruits were detected in terms of fruit quality traits. As a result
of this study, the fruit with localized and extensive surface bronzing had a lower juice volume, lower TSS/TA,
lower rind thickness, higher total soluble solids (TSS), higher titratable acid (TA) than normal fruit. It was found
that correlation coefficients of the number of carpel and fruit index were significantly lower than those of other fruit
quality characteristics. Moreover, fourth category fruits as a result of intense population damage were 16% smaller than normal fruits and number of seed was detected as zero on the fruits. |
