Comparative bio-efficacy of nuclear polyhedrosis virus (NPV) and Spinosad against American bollwormm, Helicoverpa armigera (Hubner)

ABSTRACT American bollworm (ABW), Helicoverpa armigera (Hubner), is considered as a major pest of cotton, Gossypium hirsutum, all over the globe. Due to its destructive feeding nature and continuous consumption of the same chemicals, it devolved resistant against many insecticides. Therefore, a combined application of bio- and synthetic-pesticide need to evaluate against this pest. The entomopathogenic viruses like nuclear polyhedrosis virus (NPV), a member of baculoviruses, can be the potential candidates for better control against ABW. The present study was conducted to assess the comparative efficacy of NPV and Spinosad 240SC (with the concentration of 250 mL · ha-1) against ABW in the controlled environment. The ABW was treated with different concentrations of NPV and Spinosad separately and in a combination of NPV with 0.1% Spinosad. The results revealed that highest concentrations showed highest mortality (95%) followed by 95%, 92%, 84%, 82% and 78% mortality at 1 × 109, 1 × 108, 1 × 107, 1 × 106 and 1 × 105 POBs, respectively. Spinosad when mixed in diet give 100% mortality at 0.8% followed by 50.87%, 42.10%, 29.82%, 26.31% and 22.80% mortality at 0.4%, 0.2%, 0.1%, 0.5% and 0.025% respectively. The results of this study revealed that microbial control of ABW through NPV is an effective tool. The repeated use of synthetic pesticides caused the resurgence of many insect pests, and this study results would provide useful insight to build a framework for future investigations for the management of many major insect pests.

Culture as perceived context: An exploration of the distinction between dignity, face and honor cultures / La cultura como contexto percibido: explorando la esencia de las culturas de honor, dignidad y autopresentación

Abstract: Researchers are making increasing use of the distinction between cultural logics emphasizing dignity, face, and honor. Students from eight nations including two from Latin America rated items tapping the extent to which they believed that most persons in their nation endorsed these types of mindset. Their ratings did not accord with prior beliefs as to which cultures exemplify dignity, face, and honor. However, the predictions that analytic cognition would be more prevalent in dignity cultures and contrasting types of holistic cognition would be more prevalent in face and honor cultures were supported. The belief that the logic of dignity was prevalent within one's nation was significantly associated with higher life satisfaction.

Resumen: Las investigaciones se están centrando cada vez con mayor énfasis en el uso de la distinción entre lógicas culturales, haciendo más hincapié en la dignidad, el mantenimiento del status quo estructural de una sociedad (face) y el honor. Estudiantes de 8 países, incluyendo 2 de América Latina, clasificaron elementos sobre cuán importante para la aceptación social es la dignidad o el honor para la mayoría de las personas en su nación. Las calificaciones obtenidas no concuerdan con creencias previas en cuanto a cuáles culturas promueven más la dignidad y/o el honor como guías de su comportamiento. Sin embargo, las predicciones de que los patrones de cognición analítica serían más frecuentes en culturas que se centran en la dignidad, y que los patrones de cognición holística serían más frecuentes en culturas que se centran en la honra fueron apoyadas. Adicionalmente, la creencia de que la lógica de la dignidad era frecuente dentro de cada nación se asoció significativamente con una mayor satisfacción de vida.
