Description
Behavioral aspects of Rhodnius prolixus provide the knowledge to design entomological surveillance devices. The objective was to design a trap to capture and kill a triatomine vectors of Chagas disease. For experiments, nymphs and adults of R. prolixus of the CINTROP strain were used, traps baited with biological and synthetic attractants were designed. The final prototype was compared with a commercial trap designed to capture triatomines. It was used for all experiments statistical analysis ANOVA Kruskal-Wallis test. A prototype trap was obtained, consists of two (2) truncated cones with bases of 160mm and 90mm, these serve as habitats of triatomines, the trap has slopes of 30 ° and 66 ° to facilitate the entry of these, the upper cone has at the entrance a bellows that prevents leakage once the insect has been captured. The lower base of the trap serves to put the bait and a glue for insect removal. The trap has reflective areas, in the dark serve as a visual stimulus to attract triatomines. It was confirmed in the laboratory that designed the trap was able to capture and kill all stages of R. prolixus. When it was compared with the commercial trap statistically significant differences (P = 0.775) they were not evidenced. It is a product developed by industrial designers and entomologists in the Parque Tecnológico de Guatiguará of the Universidad Industrial de Santander in Colombia. The trap is for use in homes and / or areas where they live insects.The trap design is intended for mass sale, presents disassembled the user and in accordance with stipulated guidelines can be put into operation in less than a minute. This product has patent pending protection before the Superintendencia de Industria y Comercio (SIC) de Colombía.
