SANCHEZ-CASTRO, Adayakni; MIRANDA CABRERA, Ileana  and  FERNANDEZ ARGUDIN, Basilia Miriam. Spatial and temporal distribution of Empoasca spp. (Typhlocybinae) in a bean field (Phaseolus vulgaris L.). Rev. Protección Veg. [online]. 2016, vol.31, n.3, pp.159-164. ISSN 1010-2752.

The objective of the present work was the determination of the spatial and temporal pattern distribution of Empoasca spp. and its relationship with weather variables of interest in a 26 ha black bean field  (variety Cuba Cueto 25-11) in the municipality of Güines, Mayabeque, Cuba. In the first trimester of 2015, 90 plants  were sampled each seven days. The spatial pattern distribution was calculated using Taylor´s power law (LPT): s² = am^b. The population curves were determined from the population density per sampling, and a principal component analysis was used to determine the relationship of the populations with the climate factor. The spatial distribution of the leafhopper population tended to the aggregation, and the nymph and adult population curves had a similar behaviour with a population peak in the second sampling. The sampling of twenty plants instead of thirty was determined to be enough. Humidity, temperature, and wind velocity were the variables with the greatest impact on the behavior of the leafhopper population

Keywords : population curve; spatial distribution; Empoasca spp.; Phaseolus vulgaris.
