Evaluación del uso del hongo entomopatógeno Isaria fumosorosea como control biológico para pulgón (Aphidoidea spp.) en un cultivo de pimiento (Capsicum annuum) en la provincia del Guayas.

Abstract

The objective of this study is based on establishing the effect of the dose of the entomopathogenic fungus Isaria fumosorosea for biological control against the aphid plague in a pepper crop in the province of Guayas; taking into account that this product is of great importance in the basic basket of ecuadorians. The method used was based on an experimental design with a simple randomization of 4 treatments with 10 plants each. 5 plants were randomly selected per treatment to take them as a sample. Three different doses of the product containing the fungus were applied: 1 g/L, 2 g/L, 3 g/L and the control to which water was applied. From the moment the fungus was applied, the data was recorded every 3 days and then a new dose was applied. After collecting all the data, an ANOVA analysis and a test of least significant differences (p – 0.05) were performed. The results obtained did not show any control action of the fungus towards the aphid in any of the doses, inferring that the results were affected by high temperatures and low relative humidity.
