Determinación de la actividad acaricida de extractos vegetales y otros compuestos sobre Schizotetranychus hindustanicus en cultivo de Lima Tahití (Citrus ×latifolia Tanaka ex Q. Jiménez).
Lemon Tahiti (Citrus × latifolia Tanaka ex Q. Jiménez) crops cover a large geographical area in Colombia, since the multiple uses of its fruit generate various benefits and its export presents a high degree of economic activity in the country. For these reasons, monitoring these crops of any agent that affects them becomes one of the main challenges for farmers. Schizotetranychus hindustanicus is one of the pests that affects citrus trees causing circular whitish spots on leaves and fruits, and in Colombia its presence has been reported in various departments, therefore farmers choose to use techniques based on substance use considered as the precursors of pesticides when these pests appear. Due to this, in the present study it was tried to carry out control strategies based on organic extracts derived from the Azadirachta indica (Neem) plant, since its insecticide properties have been demonstrated through various studies, as well as the Kumulus that It has been widely used but has not been evaluated in Schizotetranychus hindustanicus in Tahiti Lemon crops. Previously, the mite was identified through the identification character, which corresponds to the edeago in males. Two doses of Azadiractin-based, commercial and Emulsified compounds were evaluated in vitro; The highest mortality was presented by Emulsified Neem and Kumulus with values of 93.30 and 97.22% respectively at 72 hours. These treatments were evaluated in vivo. Subsequently, the LD50 of the Emulsified Neem was determined, which showed that at a concentration of 1.07%, the mortality of half the population at 24 hours is presented. Finally, Schizotetranychus hindustanicus was identified as the species of interest, which was inhibited by 2 of the organic compounds evaluated.
