Year two of a survey to monitor aphid populations in areas inside and outside of boll weevil eradication was conducted in the summer of 1999. Beginning this year Mississippi was involved in 3 different phases of boll weevil eradication. This survey was conducted in those 3 regions to determine the effects that ULV malathion used in the program had on aphid populations. Flaring of aphids due to boll weevil eradication was much less in 1999 than in 1998. However, early flaring of bandedwinged whitefly populations was observed in the South Delta region. This region was involved in the second season of boll weevil eradication, which has historically been the year of heaviest ULV malathion use and has thus had greatest risk of flaring secondary pests.
