Determination of Aphids in Hops

Abstract The flotation procedure for determining aphids in hops has been improved over the previously described method (Method A, This Journal, 45, 670 (1962)) by the addition of an iodine staining technique to increase visibility of the aphids and a change in the counting procedure to include, as a whole aphid, any aphid part containing a head

Abstract One new method, Total Haze of Beer After Chilling, is recommended for adoption as official, first action. Other new methods of the American Society of Brewing Chemists, which will be eventually submitted to the AOAC, are Diacetyl in Beer, Microbiological Controls, Aphids in Hops, and Physical Stability of Beer. The ASBC now has nine technical subcommittees investigating various analytical methods which may be of eventual interest to the AOAC.

Protection against aphids by seed treatment.

IN 1948, Schrader1 reported the discovery by himself and Kukenthal of the systemic insecticidal properties of bis(bisdimethylamino phosphonous) anhydride. [(CH3)2N]2PO.O.PO[(CH3)2N]2. Since then a number of papers on the biological activity of this substance has been published, the most comprehensive from the practical control angle being the one by Ripper et al.2 giving full results of field trials against hop aphids.
