LEDESMA, María Belén; ORTEGA, Carlos Alberto; GALLEGOS, Patricio  and  PAZMINO, Juan. Evaluación de la eficiencia de extractos vegetales y agentes microbiológicos para el control del barrenador de la naranjilla Neoleucinodes elegantalis. Siembra [online]. 2015, vol.2, n.1, pp.14-22. ISSN 2477-8850.  https://doi.org/10.29166/siembra.v2i1.113.

Mortality test on Galleria mellonella firststar eggs and larvae of Neoleucinodes elegantalis were conducted at the “Santa Catalina” Experimental Station at the Autonomous National Institute for Agriculture Research (INIAP), using plant extracts and microbiological agents in order to establish a representative mortality sample for both variables. The treatments that showed higher mortality were evaluated in the field to determinate the control capacity of Neoleucinodes elegantalis in the naranjilla (Solanum quitoense) crops. The evaluation was carried out during four consecutive harvests at the parish of Rio Negro in the province of Tungurahua. The results show that (Vertigo® 3.8 cm3/dm3) + (Ac. Pinion 5 cm3/ dm3) showed a control percentage of 51. 41 % followed by Bacillus thuringiensis (BT CustomBio 2.5 cm3/dm3) with a control percentage of 50.56 %

Keywords : Solanum quitoense; biological control; percentage of healthy fruit; mortality tests; Galleria mellonela.
