What is Pierce's Disease?

Pierce's Disease is a bacterial infection, which is spread by bugs that feed on grapevines, particularly the "glassy winged sharpshooter." Grapevines that become infected with PD can quickly become sick and die.

First report of a Proconiine Sharpshooter Anacuerna centrolinea (Hemiptera: Cicadellidae) in Chile, with Notes on its Biology, Host Plants, and Egg Parasitoids


  • Author(s): de Le?n, Jesse;
  • Abstract: The first representative of the leafhopper tribe Proconiini (subfamily Cicadellinae), Anacuerna centrolinea (Melichar) is reported herein from Tarapac Region in northern Chile. This species was discovered at high elevation (ca. 4000 m) in the course of a survey conducted in South America by the Agricultural Research Service of the United States Department of Agriculture for the neoclassical biological control program against the glassy-winged sharpshooter, Homalodisca coagulata (Say), in California, USA. New data are given on the biology and host plants of A. centrolinea. Information is also provided on its egg parasitoid, Gonatocerus tuberculifemur (Ogloblin) (Hymenoptera: Mymaridae), which was also the first time recorded from Chile. This discovery encourages further exploration for leafhopper egg parasitoids in northern and central regions of Chile to identify new perspective biological control agents that are more adapted to California-like climates. In addition, it is possible that G. tuberculifemur may be a good candidate for the biological control of the recently discovered H. coagulata in Easter Island, Chile
