A three-year study of this pest. Myzus houghtonensis, has shown that although engine oil emulsion, miscible oil, nicotine or a combination of either oil with nicotine will kill the hatching aphids and prevent formation of galls, it is almost impossible to obtain a practical control since the aphids migrate from plant to plant in the third seasonal generation and multiply rapidly after the migration. A strain of plant apparently resistant to their attacks gives greatest promise as a method of control. For three years these plants have been uninfested and aphids transferred to them did not injure them. Horticulturists have not been able to distinguish these from the houghton gooseberry plants which are infested. Several parasites were reared from these aphids but no marked degree of control was noted.
