“…It not only causes cosmetic damage to grape bunches, but also lowers grape production levels by transmitting various plant diseases and viruses, resulting in it characteristically being more economically damaging than any other mealybug species (Haviland et al, 2005;Daane et al, 2008;Holm, 2008;Negrisoli et al, 2013).…”

“…Mealybugs and ants are known to have a mutualistic symbiosis, whereby the ants obtain carbohydrate-rich honeydew from the mealybug, while in return providing it with protection, sanitation and transport (Mgocheki & Addison, 2009). Thus, ants potentially can increase mealybug pest problems by interfering with the augmentative and natural biological control, through assisting in their dispersal, or through decreasing the EPN efficacy by means of scavenging on EPN-infected insect cadavers (Phillips & Sherk, 1991;Baur et al, 1998;Daane et al, 2008). The most common pest ant species in South African vineyards include Linepithema humile (Mayr) (Argentine ant), Anoplolepis steingroeveri (Forel) (black pugnacious ant), and Anoplolepis custodiens (Smith) (common pugnacious ant) (Addison, 2002).…”

In South Africa, the most common method of mealybug control has been the use of chemical insecticides. Entomopathogenic nematodes (EPNs) of the of the families Heterorhabditidae and Steinernematidae potentially can be used within an integrated pest management scheme to control Planococcus ficus, the vine mealybug, which occurs on all parts of grapevine, including the roots. When Steinernema yirgalemense was applied to the soil of two vineyards with P. ficus, contained in pierced Eppendorf tubes, buried at a depth of 15 cm in the soil, mortalities of up to 50% were obtained after 48 h. The persistence of S. yirgalemense, measured using codling moth larval mortality was found to be zero in one vineyard, while in the other it was 70%, 12 weeks after application. Tests were conducted to establish the production of scavenger deterrent factors by H. zealandica and S. yirgalemense. Of the cadavers that were presented six days after nematode infection, 49% of the H. zealandica-and 60% of the S. yirgalemense-infected cadavers were left intact. Olfactometry tests indicated a significant difference concerning the number of S. yirgalemense infective juveniles (IJs) that were attracted to damaged Vitis vinifera roots and P. ficus, indicating active movement of the IJs and the attractive ability of organic compounds produced by the roots. This study shows that EPNs, and specifically S. yirgalemense, have promising potential as biological control agents for the control of P. ficus soil populations, and investigates some influential factors affecting EPNs as biocontrol agents in the agro-ecosystem.

“…Planococcus ficus has characteristics that make it particularly more economically damaging than other mealybug species (Haviland et al, 2005;Daane et al, 2008). Compared to P marilimus, P longispinus and P viburni, P ficus excretes far more honeydew per individual, and has a faster development time and a higher reproductive rate of more than 250 eggs produced per female.…”

“…Planococcus ficus is a polyphagous insect that feeds on a wide range of host plants apart from just Vitis vinfera (grapevine) (Daane et al, 2008;Walton et aL, 2009). Such feeding habits enable the provision of an unwanted source population of the pest outside of vineyards (Haviland et al, 2005).…”

The vine mealybug, Planococcus ficus (Hemiptera: Pseudococcidae), which is the dominant mealybug species in South Africa, is a severe wine and table grape pest and disease vector. Their increasing resistance to chemical pesticides and cryptic lifestyles have led to the search for new control methods. Entomopathogenic nematodes (EPNs) belonging to the famifies Heterorhabditidae and Steinernematidae are deadly insect pathogens. This paper gives valuable background information on F ficus and EPNs, while paying particular attention to the potential use of South African EPN species as biocontrol agents against F ficus.
