numbers on July 15 and browning potato fields in Suffolk County.

cases. 
POTATO APHID ( Macrosiphum solanifolii Ashm. ) 
Massachusetts A. 12 Bourne (August 23): Aphids were very generally prevalent 
at the Market Garden Field Station at Lexington on market 
garden crops, particularly on tomatoes. The particular species 
of aphid was not reported.

showers have reduced the numbers of lice in Nassau County. 
Indiana H. F, Dietz (July IS): Earlier in the season tomatoes were 
attacked by the potato aphid. These infestations were pretty 
well cleaned up by the ladybird beetles, especially the 
convergent ladybird, the nine-spotted ladybird, and the maculate 
ladybird. As a result of this infestation, however, many 
tomatoes are showing infection with mosaic and spindling 
sprout disease at this time,
