New York, N. Y. State Coll. Agr. News Letter (June): Pea aphids are show- 
ing up on peas to some extent in Niagara' County. One cannery imported 
ladybeetles and liberated them in pea fields in an endeavor to control 
the aphids. Some canners are dusting. 
Chio. T. E. Porks (June 26): A telephone call today reports that the pea 
aphid is badly injuring peas grown for a canning factory at Wauseon, 
Indiana. J. J. Davis (June 25): The cool spring has been unusually favor- 
able to aphids, which are exceedingly abundant on garden crops, especially 
peas. 
Michigan* R, Hutson (June 11): The pea aphid Is fairly ebundant on alfalfa 
at Lakeview, Vestaburg, Frankfort, and Fremont. Also observed on peas 
at Ithaca on May 20, but only a few winged migrants were present, 
"Wisconsin. E. L» Chambers (June 20): Reports received from all over the 
State wherever peas are grown extensively for canning, indicate serious 
infestations in spots and an abundance of them on alfalfa, 
J. E. Dudley, Jr., (June 18): A heavy infestation of aphids in alfalfa 
in southern Wisconsin followed a generally cool, wet spring, which is not 
supposed to be favorable for rapid multiplication of the. insect. Heavy 
and general flights occurred late in May to peas. Infestation built up 
rapidly but was reduced by rainstorms and cool weather early in June; 
again built up rapidly following several warm, humid days, until many 
fields of peas less than a foot high were threatened with serious injury. 
The' prolonged recent rains have again reduced the infestation considerably. 
North Dakota. J. A. Munro (June 18): The aphid is abundant on sweet peas 
in Fargo and vicinity. 
Kansas. E, T. Jones (June 2°/): In view of the favorable conditions for 
aphid development, sweepings made from June 14 to 2.1 in alfalfa fields in 
nine counties in eastern Kansas have shown a remarkable scarcity of aphids. 
In general the aphid population, which was increasing in April, has dropped 
back to a low point. Predatory insects which were very abundant two months 
ago are now conspicuously absent. Presumably the large numbers of lady- 
beetles and nabids ( Nab is ferus L.) present in April have been reduced to 
practically none through starvation, 
Mississippi, C. Lyle (June 22): Considerable damage to peas by .the pea 
aphid was reported from Hamilton on June 1<9» 
Idaho, C, Wake land (June 22): Pea aphids are almost entirely absent from 
the pea fields of northern Idaho this year, paras it izat ion was very heavy 
last summer, so that the hold-over population of the aphid was light, 
LadybeetleB hibernated successfully in enormous numbers and migrated to 
pea fields early, so there is little possibility of pea aphid populations 
increasing sufficiently to cause any damage.
