Evaluación del control etologico y biologico para la mosca blanca (Trialeurodes vaporariorum W.) en tomate cherry (Solanum lycopersicum L.) var. San Marzano en invernadero.

Abstract

This research aimed to evaluate the ethological and biological control of the whitefly Trialeurodes vaporariorum W. on cherry tomato Solanum lycopersicum L. var. San Marzano in greenhouse. A Randomized Complete Block Design (RCBD) was used with three replications in which four treatments (T) were applied as T1 (Neem-X) based on neem extract Azadirachta indica, T2 (Lecanitic) based on the entomopathogenic fungus Lecanicillium Lecanii, T3 (Yellow chromatic traps) and T4 (Absolute control) each one of these controls was applied 37 days after transplanting the crop with a dose of (3 cc/L-T1, 1 gr/L-T2 and T3-30 units of chromatic traps of 35*50 cm) at a frequency of 7 days. To gather collection 10 plants were chosen for each treatment and repetition, so parameters such as: Incidence percentage in adult and nymphal stage, severity percentage, efficacy percentage and yield in kg/ha were evaluated. As a result, a lower percentage of incidence (adult-nymphal) and severity was obtained with T1 based on neem extract, the highest efficacy in the control of Trialeurodes vaporariorum in adult and nymphal stage with 57.90%-54.95% was obtained by the application of treatment T1, and it was the best control compared to other treatments with a yield of 35390.63 kg/ha and a benefit/cost ratio of 2.20 dollars. It is concluded that T1 based on neem extract (Neem-X) obtained a higher efficacy in the control of greenhouse whitefly, in addition this treatment obtained a higher yield and a better benefit/cost ratio. It is recommended to use (Neem-X) to control Trialeurodes vaporariorum and carry out research in different doses in other production areas of solanum lycopersicum.
