Biology and harmfulness of Tetranychus tumidus (Banks) in the banana clone “Z-30” (Musa paradisiaca L)

Abstract

The research was conducted at the laboratory and field level to evaluate the incidence of Tetranychus tumidus on banana crop clone "Z-30". It was studied the bioecology of the mite on the leaves and the influence of the mite on vitroplants, as well as the toxicity of different acaricides on T. tumidus in the crop. It was determined that the mite completes all its phases on the leaves, with a longevity for females of 23.5 days and a hatching percentage of 96.29%, reaching population levels with averages above 300 mites. plant-1, harmful to the growth and development of the vitroplants. The greatest damage occurred with infestations between 50 and 75 mites. plant-1, reducing height, fresh and dry mass. The timely application of an acaricide such as propargite and carbosulfan, highly toxic to a population of T. tumidus in the early stages of the crop cycle, is proposed.
