| Popis: | Mealybug Paracoccus marginatus Williams and Granara de Willink (Hemiptera: Pseudococcidae) is an important pest of physic nut Jatropha curcas L. (Euphorbiaceae), infestations can be severe and dispersion is unknow. The objective was to determine the temporal and spatial dynamics in four experimental areas in 2014 and 2015 in Yucatan, Mexico. Incidence (mealybug-infested or uninfested plants) was assessed from May to July at nearly-regular day intervals. Temporal analysis was carried out using deterministic, growth epidemiological models, whereas spatial analysis was conducted through mapping, randomness tests and spatial autocorrelation. The exponential and logistic models described the incidence of mealybugs in 2014 with a coefficient of determination (R2 = 0.9 and 0.9); mean square error (MSE = 0.66 and 0.70); and P value |
