Maine. J. Hawkins (Julv IS): A very light general infestation in central Maine 
developed into serious proportions but failed to injure peas extensively, 
owing in part to weather conditions, parasites, and predators.

destructive throughout the State, so abundant in some localities that 
crops in many fields were completely destroyed, severe damage extending 
over considerable areas, particularly on late varieties of peas where con- 
trol measures were not effective. Injury in many localities was aggravated 
by prolonged periods of dry weather and by mosaic. In areas whore the aphid

continued thro\igh most of the week beginning June 25. Aphids still abun- 
dant in fields of later pi, -anted peas.
