Bananas are one of Ecuador's main export crops, constituting the most important agricultural activity in the country's economy. As with other crops, musacea production is subject to various phytosanitary problems that affect yields, for example, the black weevil (Cosmopolitos sordidus). It is an insect pest that attacks the root system affecting the vegetal’s normal absorption of nutrients and water. Severe attacks may even cause the plant to overturn. This study evaluates the efficiency of two variations of ethological traps using banana pseudostem for the black palm weevil control. These are the sandwich and V-type traps, located at heights of 25 cm, 50 cm, and 100 cm; they are considered the treatments. The evaluations were carried out from the third day after the installation of the traps, with five evaluations per treatment in total. The results showed that the best treatments were the traps placed at 25 cm, whereas the sandwich trap at 25 cm was the most effective treatment with an average specimen capture rate of 11.50 specimens. The highest efficiency was three days after its installation, with an average of 34 captures, decreasing in the last evaluation after 15 days with an average of 10.25 captures. The traps also captured specimens of the striped weevil (Metamasius hemipterus) and the palm weevil (Rhynchophorus palmarum).
