    In plantations there are groups of pest insects that affect the orite crop, the striped weevil (Metamasius hemipterus L.) is one of the main pests of economic importance. These insects cause production losses due to deterioration of the plantation or by overturning of the plants. The objective of this research was to determine the biocontrol capacity of entomopathogenic fungi to control the striped weevil (Metamasius hemipterus) in the orite crop. This research was carried out in a baby banana plantation, located in the La Maná Canton, province of Cotopaxi. Ten adult striped weevil insects were captured and placed in each jar with 100 grams of pseudostem. The experiment had a completely randomized design (DCA), with a total of three treatments with five repetitions. The analysis of variance was carried out and the Tukey test was performed at 5% for the sources of variation that were significant. To carry out the analysis, the statistix 10 program was used. The data collected were the percentage of mortality and the action time of entomopathogens. It was evidenced that the application of entomopathogenic fungi Beauveria bassiana (Bassi 1879) and Metharizum anisopliae (Metschnikoff 1837) obtained a good percentage of biocontrol on the striped weevil (Metamasius hemipterus) with values of 79.86 and 77.86% respectively in tests of laboratory, because high mortality rates were obtained with the treatments established in the experiment. The application of entomopathogenic fungi carried out in this experiment produced a high mortality in a time similar to other tests carried out at the laboratory level.
