Abstract:In 1969, 11 releases of unsexed, sterilized, and dyed adult Drosophila melanogaster Meigen were made directly onto 76 acres of commercial tomatoes (avg. ca. 48,000 flies/acre/release) in New Jersey from June 24 to Sept. 4 for suppression of this insect in those fields.
Suppression of native flies was excellent (avg. ca. 95%) in the release area, based on populations in untreated checks; and the ratio of sterile (released) to native flies averaged ca. 75:1 to about Aug. 7. Thereafter, though the tomato fields in the check area were sprayed by the growers at their discretion with diazinon at a rate of 0.5 or one lb AI/acre application for the control of Drosophila, significantly fewer native flies (avg. ca. 39%) were trapped in tomatoes in the release area from Aug. 12 to Sept. 9. Also, significantly fewer Drosophila eggs (avg. ca. 65%) were laid in ripe tomatoes distributed in tomato fields in the release area from Aug. 14 to Sept. 12. Thus, direct field releases of sterile flies were even more effective in suppressing development of D. melanogaster than were sprays of diazinon applied by the growers.
