After this, be sure to manually pick the nymphs to prevent them from causing more damages when they fully mature. They will extract the juice of their host plants, which deprives the latter of the nutrients that are essential for its survival. Feeding causes leaves to develop yellow and brown margins, which is known as ‘hopperburn,’ and growth may become stunted. That means the queen of the colony that I spotted from the back porch moved in long before we started renting last winter. Restriction fragment length polymorphism (RFLP) analysis and sequence comparison based on the F2nR2 fragment of the 16S rRNA gene revealed the presence of six 16S phytoplasma ribosomal groups and eight subgroups in E. incisus (16SrI-R, 16SrI-F, 16SrII-E, 16SrIII-B, 16SrIX-C, 16SrIX-E, 16SrXI-G and 16SrXII-A). 2003, Mazzoni et al. The presence of diverse phytoplasmas in three spittlebug species, Aphrophora alni, Lepyronia coleopterata and Philaenus spumarius, indicates that these xylem feeders actually ingested phloem sieve cell contents during feeding on phytoplasmai-nfected plants, bringing into focus the question of whether some of such xylem feeders might act as occasional vectors of phytoplasmas. Much of the published literature about Ligurian leafhopper management comes from Europe, rather than the United States, where it is still a relatively recent arrival. In this last vineyard for two consecutive years (2007 and 2008) Plant protection practice cannot prevent the establishment and spread of vector populations, especially in sustainable production systems, which forms more than 70% of the total Austrian viticulture area. 2004, Sabaté et al.
