                                    Citation: Neven, L.G., Hansen, J.D., Spotts, R.A., Serdani, M., Mielke, E.A., Bai, J., Chen, P.M., Sanderson, P.G. 2006. Effect of a high-pressure hot water washing system on fruit quality, insects, and disease in apples and pears. Part IV: Use of silicone-based materials and mechanical methods to eliminate surface arthropod pests. Postharvest Biology and Technology. 40:230-235.Interpretive Summary: The presence of surface arthropods on commercially processed apples and pears poses a problem when these fruits are exported to countries where there are either limits on the numbers of eggs or a total quarantine restriction against these pests.  Removal of the mite and other arthropod eggs, such as European red mite and codling moth eggs, may be enhanced by the use of a surface cleaning system, such as a hot water, high pressure sprays.  In addition, organosilicones, like SilWet L-77, have shown great promise in killing spider mites. It was unclear if these chemicals could also facilitate the removal of arthropod eggs from the surface of fruits. Researchers at the USDA-ARS Yakima Agricultural Research Laboratory in Wapato, WA and the Mid-Columbia Agricultural Research and Extension Center of Oregon State University determined that high pressure washing was more effective in removal of codling moth and European red mite eggs than organosilicone dips or hot water sprays.  This technology will aid in the export of pome fruits where the presence of arthropod eggs can disrupt trade.
