Whiting, D.C., Hoy, L.E., Maindonald, J.H., Connolly, P.G., & McDonald, R.M. 1998 High-pressure washing treatments to remove obscure mealybug (Homoptera : Pseudococcidae) and lightbrown apple moth (Lepidoptera : Tortricidae) from harvested apples.. Journal of Economic Entomology 91(6): 1458-1463.
Notes: Mixed life stages of obscure mealybug, Pseudococcus viburni (Signoret), and late 1st-instar or early 2nd-instar lightbrown apple moth, Epiphyas postvittana (Walker), on 'Royal Gala apples (Malus domestica Borkhausen) were exposed to standard packhouse processing with and without addition of high-pressure apple washer treatments. Insect removal and mortality were assessed. After standard packhouse processing approximately 60% of P. viburni remained on their host apples. The two high-pressure apple washer treatments (500 and 800 psi at 2.0 rods/s) were equally effective and significantly reduced the number of P. viburni on apples compared with the packhouse control.
