Insecticide effect of cyantraniliprole on tomato moth Tuta absoluta Meyrick (Lepidoptera: Gelechiidae) larvae in field trials

The tomato moth (Tuta absoluta Meyrick, Lepidoptera: Gelechiidae) has traditionally been managed in Chile with organophosphate, pyrethroid, and nereistoxin insecticides; all of these have wide action spectra and high toxicity and many of them have developed rapid resistance. It is therefore importan...

The objective was to evaluate the effectiveness of T. absoluta control with cyantraniliprole insecticide, which has desirable characteristics for programs of integrated pest management of tomato; we thus performed three trials in the 2009-2010 and 2010-2011 seasons in the Coquimbo Region, Chile. These trials evaluated the control of T. absoluta using different doses of two formulations: cyantraniliprole 10 OD (oil dispersion) with or without surfactants (Dyne-Amic, Codacide) applied to leaves and cyantraniliprole 20 SC (suspension concentrate) applied to soil. Trials used a randomized complete block design with four replicates. The effect of treatments was compared with standard insecticides and a control without insecticide. The degree of control was estimated by foliar and fruit damage at harvest. Results indicate a reduction in fruit damage between 75% and 85% for foliar applications and 82% for soil applications of cyantraniliprole.
