Abstract:
The influence of planting dates on aphid population growth in head lettuce was measured over a 5 year period to identify planting windows during the season when lettuce is at risk from aphid infestations. Small, untreated 0.2 acre plantings of head lettuce were established beginning in October with final harvest occurring in April. Plant samples were conducted weekly to estimate the numbers of aphid per plant. Based on these studies, planting date and temperature likely has a strong influence on seasonal abundance and damage caused by aphids. Green peach aphid was the least abundant aphid during the 5 year period, and foxglove aphids appear to be increasing in abundance over the past 3 years. All aphid species have the potential to economically contaminate lettuce, particularly in the November and December planting windows.
