Since the grape Pierce disease (PD) was reported in Taiwan in 2002, Kolla paulula is a commonly found leafhopper at PD infected areas. The study showed that K. paulula is a potential insect vector for both PD and pear leaf scorch. In order to establish integrated management techniques for the environment of grape viticulture in Taiwan, the authors describe how to apply the data on the integrated management of the potential insect vector. Data are from the study conducted during 2009 to 2013. The results of the study include life history of K. paulula, population dynamics, habitats and host ranges.
