Efeito de classes de solo e umidade na profundidade de pupação e viabilidade pupal de Bactrocera carambolae Drew & Hancock (1994)

Abstract

Bactrocera carambolae is a quarantine pest present in Brazil and today represents the main phytosanitary barrier for the exportation of fresh fruits produced in the country.Pupation depth estimates for B. carambolae are important for the development of sampling and management techniques for this exotic species. In this work, the effect of soil classes and moisture on the pupal phase of this insect was evaluated. Three soil textural classes and four moisture levels were used, 0%, 30%, 60% and 90% of the field capacity of each soil, totaling 12 treatments, with 6 repetitions. Pupation depths varied from the surface to the fifth centimeter. The soil class showed greater significance in relation to the pupal development of B. carambolae. Moisture was not significant for pupation depth and emergence, but correlated with soil showed strong interaction, showing an increase of emergence as the humidity increased in clayey loam and sandy-clay loam soil. The methodology developed for the work proved to be efficient for works of this nature
