Antitrogus morbillosus Tableland The extent of damage by the grubs is pasture scarab dependent on the level of infestation, seasonal conditions and grazing management. Usually worsened in shallow soil and where plant growth is restricted by dryness and overgrazing, which reduces the plants capacity to replace severed roots (Goodyer and Nicholas, 2005).

(Goodyer and Nicholas, 2005) Othnonius batesi soil scarab (Goodyer and Nicholas, 2005) Rhopaea spp. Pasture white grub (Goodyer and Nicholas, 2005) Pruinose Larvae damage the roots. In severe Sericesthis geminata scarab infestations the roots can be entirely Sericesthis nigrolineata removed so that the pasture is torn up by Dusky pasture grazing animals or birds searching for larvae. scarab Less severe damage can cause water stress as a result of root loss and an inability to recover from defoliation (Gregg, 1997). Tenebrionidae Pie dish Larvae attack germinating and the beetles stems of seedlings. Established pastures can support substantial populations with little effect, but newly seeded pastures can be severely damaged (Gregg, 1997).
