This work aimed to evaluate the toxic effect of the extracts from the leaves of Azadirachta indica (neem)
as a substitute for conventional insecticides applied in Sitophilus oryzae (rice weevil) and as an alternative to mitigate the harmful effects of synthetic insecticides. Solid-liquid extraction with water
ethanol
ethyl acetate and hexane by soaking for 24 hours at room temperature and Soxhlet extraction for 5 hours. The extracts were diluted at a concentration of 3% w / v by rotary evaporation. The methods of impregnation substrate and contact of nonporous surfaces were used to measure the toxicity. As positive controls were used Malathion and Deltamethrin at 10 ppm. High performance liquid chromatography (HPLC) was used to characterize the extracts and AZA
the compound attached to the insecticidal activity. We used UV-Vis spectrophotometry to determine the presence of other active compounds. After 144 hours of exposure
the greater toxic effect corresponded to ethanol extract by maceration with 83% mortality ± 8 in contact with non-porous surface
which showed statistically significant differences compared to negative controls
confirming their insecticidal activity Weevils adult rice. Similarly
this extract were obtained 0.01 ± 1.28% w/v AZA
the more of this compound to the other extracts. The results show that leaf extracts of neem have insecticidal and could be a replacement to conventional insecticides to control rice weevil

Este trabajo tuvo como objetivo evaluar el efecto tóxico de los extractos provenientes de las hojas de Azadirachta indica (nim), como sustituto de los insecticidas convencionales aplicados en Sitophilus oryzae (gorgojo del arroz) y como alternativa para mitigar los efectos nocivos de los insecticidas sintéticos. Se realizaron extracciones sólido-líquido con agua, etanol, acetato de etilo y hexano por maceración por 24 horas a temperatura ambiente y extracción Soxhlet por 5 horas. Los extractos fueron llevados a sequedad por rotaevaporación y rediluidos a una concentración de 3% p/v. Para medir la toxicidad en los individuos se emplearon los métodos de impregnación de sustrato y de superficies no porosas. Como controles positivos se utilizaron Deltametrina y Malatión a 10 ppm. Para caracterizar los extractos y determinar la presencia de AZA, compuesto al que se le atribuye la actividad insecticida, se empleó cromatografía liquida de alta resolución (HPLC). De la misma manera, se utilizó espectrofotometría UV-Vis para determinar la presencia de otros compuestos activos. Después de 144 horas de exposición, el mayor efecto tóxico correspondió al extracto etanólico por maceración con 83%±8 de mortalidad por contacto con superficie no porosa, el cual mostró diferencias estadísticamente significativas respecto a los controles negativos, confirmando su actividad insecticida en gorgojos del arroz adultos. Igualmente, de este extracto se obtuvieron 1,28%±0,01 p/v de AZA, la mayor cantidad de este compuesto respecto a los demás extractos. Los resultados muestran que los extractos de hoja de nim, tienen efecto insecticida y podrían ser un reemplazo a los insecticidas convencionales para el control del gorgojo del arroz. |
