“…Mycoparasitic relationships display a range from biotrophic, where nutrients are acquired from living host cells, to necrotrophic, where the fungal prey is killed and subsequently consumed by the mycoparasite (Barnett, 1963; Karlsson et al., 2018). Certain mycoparasitic species are used as biological control agents (BCAs) against plant pathogenic fungi in agricultural production settings (Jensen et al., 2016), and their use has been demonstrated to be a more sustainable and less hazardous alternative to chemical pesticides or antimicrobial compounds in agriculture (Harman et al., 2004; Vardhan et al., 2013). Knowledge‐based improvement of the application and use of fungal mycoparasites as BCAs requires an understanding of the mechanistic basis for the interaction between parasite and prey.…”

Background and Objective: In India, the application of natural Entomopathogenic Nematodes (EPNs) are considered potential biological control agents against soil-borne insect pests last 4-5 decades. Local isolates of EPNs have strong potential and are usually more effective for controlling indigenous insect pests as they are adapted to the local environmental conditions and the insect pest species. The present study aims to isolate indigenous EPN from the eastern part of Uttar Pradesh, India, to test the occurrence and their use as a biological control agent in IPM. Materials and Methods: The distribution, occurrence and diversity of Steinernema seemae entomopathogenic nematode community were investigated and isolation of S. seemae was carried out by using the galleria wax baiting technique and morphological identification methods which reveal that it belongs to the genus Steinernema. Further study was done to examine S. Seemae virulence's impact on soil temperature and soil moisture. Results: The effect of temperature, 12, 15, 20, 25 30 and 37°C and relative humidity, 35, 55, 85 and 100% on S. seemae was observed and they were listed against the Helicoverpa armigera larvae. The results reveal that, at 25°C temperature and 85% relative humidity, S. seemae is a more effective bio-control agent in terms of penetration and multiplication against host H. armigera larvae under controlled conditions. Conclusion:The EPNs isolated from the soil samples increase the information of S. seemae species showing bio-control activities, which was available for developing suitable bio-control strategies as well as enabling us the recognition of bio-control EPN. EPN species would serve as an alternative to chemical pesticides and fit well in integrated pest management.

“…En el Centro de Investigación Frutícola Olerícola de la Facultad de Ciencias Agrarias de la Universidad Nacional Hermilio Valdizan (CIFO), considerado como un Banco de Germoplasma de 22 variedades de palto, el control de ácaros está limitado al uso exclusivo de abamectinas y azufre; en las últimas décadas estas plaguicidas han sido cuestionados y cada vez más limitados en sus usos (Reyes-García et al, 2007). Existen otras alternativas de control entre ellas están el uso de bacterias habitantes del suelo como el Bacillus thuringiensis, B. subtilis, cuya formulación es a base de esporas de Bt (Vardhan et al, 2013), por ejemplo, Torres y Hernández (2018).

El manejo de plagas en los cultivos de palto en la región Huánuco se basa en el uso de pesticidas de amplio espectro que son muy agresivos con el medio ambiente y no siempre su aplicación y dosificación es realizada de manera correcta, lo cual implica mayores riesgos para la salud, resistencia, resurgencia de nuevas plagas y desaparición de la fauna benéfica. El uso de entomopatógenos es un método de control reciente viable y eficaz. En ese contexto, se evaluó la eficacia de Bacillus thuringiensis var. kurstaki, B. subtilis y caolín en la lucha contra el ácaro Oligonychus yothersi en los cultivos de palto. Se utilizó el diseño completamente al azar con cuatro tratamientos y tres repeticiones, la muestra estuvo constituido de tres árboles por unidad experimental, la variable respuesta fue el número de ácaros móviles previo y post aplicación en 10 hojas maduras, registradas de manera aleatoria en la parte media y baja de la planta. Se calculó la efectividad biológica mediante la fórmula Henderson-Tilton, los datos resultantes fueron sometidos a un análisis de varianza y prueba de comparación de medias de Duncan con α= 0,05 y 0,01. Los resultados demuestran alta efectividad de B. thuringiensis var. kurstaki en la reducción del grado de infestación, pasando del grado 6 al grado 2 a los 60 días y grado 1 a los 105 días (ausencia ácaros/hoja), así como alto porcentaje en la reducción de la incidencia (91,51 %) a los 15 días después de la aplicación del producto.
