Physicochemical quality parameters in guava fruit with presence of larvae of Conotrachelus dimidiatus (Champion) (Coleoptera: Curculionidae)

Abstract

Trandomizedhis fruit research with presence experimentalaimed of to Conotrachelus evaluatedesignsome dimidiatus withphysicochemical15 and (Champion) 24 replicatesquality in larval wasparameters stage. established. A completely in guavaThe weight, firmness, diameter, length, color, total soluble solids, titratable acidity and vitamin C in fruit of guava variety Media China were determined. The presence of C. dimidiatus larvae significantly decreased fruit weight, length and equatorial diameter, presenting values of 20.73 g, 37.96 mm and 31.36 mm, respectively. Vitamin C content decreased from 11.71 to 2.80 mg∙100 g-1. The growth and development of C. dimidiatus inside the fruit makes it necessary to implement efficient control methods that allow the harvesting of innocuous fruit for consumption.
