The featureless readings were interpreted as an indication of the presence of kaolin.
Each dish was then sprayed, using a hand-held mister, with either water or the kaolin particle suspension.
An additional experiment examined the effects of the kaolin particle film on the settling of second-instar nymphs over a shorter timeframe.
The needle-like stylets may be able to penetrate between the particles, so that any disruption by the kaolin particle film is minimal or negligible.
We conducted a series of laboratory experiments to investigate the mode of action of kaolin against aphids.
There have been very few laboratory studies to investigate the mechanisms of action of kaolin against sap-feeding insects.
The clay mineralogy of this soil is dominated by kaolin (65+80%) with sub-dominant illite (10+20%) and vermiculite (1+5%).
The corporation expected eventually to extract 400 tons of kaolin per day, which would require 200 tons of firewood per day.
