Análisis geoestadístico de poblaciones de huevos de Aeneolamia varia ( Hemiptera:Cercopidae ) en caña de azucar

In order to analyze the spatial variation of eggs of Aeneolamia varia (spittlebug) in sugar cane, a grid in field was drawn. It consisted of 60 geo-referenced monitoring points with a sub-metric satellite receiver. Soil samples were taken around the cane noodles at each point. Once the samples were sieved, the insect eggs were removed and classified as total and fertile. Through the application of formulas were determined the fertility, amount of total eggs and fertile per hectare. Subsequently with the information obtained, a database was formed. With the use of geostatistical techniques, we obtained the theoretical models that best describe the spatial structure through semivariograms and generated estimation maps by means of the krigeago technique of the measured variables. The results indicate that the spherical model is the one that best describes the spatial structure, which is added in the egg stage of candelilla, which was corroborated by the maps of density of total eggs put in the test. In terms of control, these results generate essential information for the development of agroecological and insect precision management tactics in the cultivation of sugarcane.
