Estudio comparativo de la población de himenóptera en cultivo asociado y monocultivo de quinua (Chenopodium quinoa L.) en seis localidades de la provincia de Chimborazo.

Abstract

This research was conducted in the towns of Nitiluisa, San José de Gaushi, San Vicente de Luisa, Ocpote, Lupaxi central and Achullay in Chimborazo province. A comparative study of the population of Hymenoptera in associated crops and Quinoa monoculture (Chenopodium quinoa L.) was carried out. The GDETERRA laboratory was used for the research, and work was conducted in situ. Two techniques were applied for the collection of insects of the order Hymenoptera. One by placing yellow plates with soap and water solution, these traps were placed 40 cm above the ground with the help of wooden stakes. Once traps were set after 24 hours, the insects trapped in the solution were collected and transferred to plastic bottles containing 70% alcohol. This process was repeated for three days, during which the last collection was made for subsequent identification in the laboratory. With the entomological jama with random sampling in a zig-zag pattern within each experimental plot for 20 minutes, once captured, they were placed in transparent plastic vials with 70% alcohol in Eppendorf tubes for subsequent identification in the laboratory. In the localities of the low quinoa production zone (Chenopodium quinoa L.), there was a richness composed of sixteen families of the order Hymenoptera and an abundance of 224 individuals. In the localities of the high quinoa production zone (Chenopodium quinoa L.), there was a richness composed of fourteen families and an abundance of 333 individuals. It is recommended to extend the collection time of the order Hymenoptera in the quinoa crop (Chenopodium quinoa L.) to learn more about the richness of Hymenoptera associated with the quinoa crop.
