Description
Summary:Tetranychus urticae is an important pest associated with strawberry, due to its high densities and plant damage. Farmers use acaricides in large volumes without complying with the window between the last application and harvest, resulting on toxic residues in fruits, as well as pest populations resistant to pesticides, decrement of beneficial organisms, mammalian toxicity and environmental pollution. Therefore, it is necessary to generate new alternatives for the control of this mite. The aim of this work was to evaluate the toxic effect of commercial neem-based products on the mites T. urticaeand Phytoseiulus macropilis, through a combined analysis using both, lethal and sublethal concentrations. Tetranychus urticae populations were controlled in strawberry plants when neem was used at or below LC95 concentrations. The application of the neem-based products, Neem Pro, Organic Neem and Natuneem at CL95, and when the instantaneous predator’s rate of population increase ri = 0.1, represents a viable alternative to be considered for the control of the phytophagous mite T. urticae.
