development of a multiplex pcr for identification of vineyard mealybugs.	a simple molecular tool was developed and tested to identify seven mealybug species found in north american vineyards: pseudococcus maritimus ehrhorn, pseudococcus viburni (signoret), pseudococcus longispinus (targioni-tozzeti), pseudococcus calceolariae (maskell), planococcus ficus (signoret), planococcus citri (risso), and ferrisia gilli gullan. the developed multiplex pcr is based on the mitochondrial cytochrome c oxidase subunit one gene. in tests, this single-step multiplex pcr correctly i ...	2011	22217778
seasonal phenology of ferrisia gilli (hemiptera: pseudococcidae) in commercial pistachios.	the mealybug ferrisia gilli gullan is a serious new pest of pistachios in california. it was first found near the town of tulare in the late 1990s and has since spread to orchards in most pistachio-producing regions of the state. the seasonal phenology of f. gilli was evaluated in a commercial pistachio orchard in tulare county during 2005 and 2006. during both seasons e gilli overwintered as small nymphs and had three complete generations per year. mealybug population densities were low and rem ...	2012	23156164
seasonal biology of ferrisia gilli (hemiptera: pseudococcidae) in california sierra foothill vineyards.	the mealybug ferrisia gilli gullan is an emerging pest of wine grapes grown in california's sierra foothills. a relatively new species, it had previously been recorded as a pest of pistachio, almond, and ornamentals. it was first reported on grape in el dorado county in 2003 and has since established and spread. nondestructive monitoring of grape vine sections was conducted in untreated vineyard plots and compared with destructive sampling conducted in grower-treated plots in 2008 and 2009 to de ...	2013	24020286
crop loss relationships and economic injury levels for ferrisia gilli (hemiptera: pseudococcidae) infesting pistachio in california.	ferrisia gilli gullan (hemiptera: pseudococcidae) is a new pest in california pistachios, pistacea vera l. we conducted a 3-yr field study to determine the type and amount of damage caused by f. gilli. using pesticides, we established gradients of f. gilli densities in a commercial pistachio orchard near tipton, ca, from 2005 to 2007. each year, mealybug densities on pistachio clusters were recorded from may through september and cumulative mealybug-days were determined. at harvest time, nut yie ...	0	26470369
ferrisia gilli (hemiptera: pseudococcidae) transmits grapevine leafroll-associated viruses.	several mealybug species are vectors of grapevine leafroll-associated viruses (glrav), which cause the economically important grapevine leafroll disease in grape-producing regions worldwide. the mealybug ferrisia gilli gullan is a new pest of grapevines in el dorado county, located in the sierra foothill wine-growing region of california. glrav species 1, 2, 3, and 4lv have been detected in vineyards with symptomatic vines in the sierra foothills. we conducted controlled virus acquisition and tr ...	2016	27329635
