Abstract
Introduction: Copturus aguacatae is one of the most important pests of avocado plantations in Estado de México. The presence of this insect represents a risk for avocado production.Objectives: To study the spatial behavior of adult population of C. aguacatae using geostatistical techniques in avocado plantations in Estado de México. Methodology: A total of 400 7-year-old cv. Hass trees were selected and georeferenced in the municipalities of Temascaltepec and Tenancingo, Estado de México. Adult insects of C. aguacataewere collected using sticky traps baited with a commercial adhesive. For geostatistical analysis, experimental semivariograms were performed and fitted with theoretical models using the Variowin program. Infected surface maps were generated with the ordinary kriging technique, and graphical representation was provided with the Surfer 16 software.Results: The spatial behavior of the insect is observed in clusters within the plots. In some months, infestations were distributed over 100 % of the surface, but with variable population densities. These results can improve pest detection and sampling programs, as well as control measures on specific areas of infestation.Study limitations: No insects during some sampling periods.Originality: Use of geostatistical methods as a tool to know the spatial distribution of pests in the avocado plantations in Mexico.Conclusions: Including geostatistical methods in the management of C. aguacatae can help avocado growers, because it it provides a more precise knowledge of their spatial behavior.
