Item Analizar el comportamiento del insecto Dalbulus maidis, vector del complejo del achaparramiento del maíz, mediante el uso de herramientas de SIG en Roldanillo, Valle del Cauca.(Universidad Santiago de Cali, 2024-05-31) Nieto Valencia, Andrés Fabricio; Escalante Caicedo, Ana BelyThe maize crop in Colombia is currently on alert due to the constant increase in the populations of the insect Dalbulus maidis and the transmission of the disease of the "stunting complex" in the different regions of the country with reductions of up to 90% in yields. One of the main activities for decision-making in the health of a crop is the monitoring of pests and diseases.In this study, this insect was monitored through weekly monitoring in both study plots from its planting date until approximately 40 days after planting with a modification in the monitoring methodology suggested in the "Dalbulus maidis Management Manual". In both cases, a slight increase in insect populations was observed from the first to the last evaluation, although always below the action threshold (0.7 insects per plant), which suggests that the environmental conditions of the evaluated period and the agronomic management of farmers in the area positively influenced management and control. In addition, some meteorological variables were statistically analyzed through a trail analysis those that can influence the incidence of the insect, of which two of them stood out (Vapor pressure deficit and relative humidity) with a positive correlation with the threshold of action of Dalbulus maidis.
