<abstract xmlns="http://www.w3.org/1999/xhtml"> Field experiments conducted in North Carolina during 1964-65 to compare the residual effectiveness of insecticidal sprays against the tobacco flea beetle, Epitrix hirtipennis (Melsheimer), on flue-cured tobacco showed that, for the number of days indicated after application, the following treatments provided control similar to that obtained with 1 lb / acre of DDT: [1] for 10 days, 0.5lb of carbofuran, Dasanit® (o,o-diethyl o-[p-(methylsulfinyl)phenyl]phosphorothioate), dimethoate, Gardona® (2-chloro-1-(2,4,5-trichlorophenyl) vinyl dimethyl phosphate), Imidan®(o,o-dimethyl S- phthalimidomethyl phosphorodithioate), and Supracide® (S-((2-methoxy-5oxo-Δ2-1,3,4-thiadiazolin-4-yl)methyl) o,o-dimethyl phosphorodithioate), and 1lb of aminocarb and MCA-600 (benzo[b]thien-4-yl methylcarbamate), [2] for 6 days, 0.25 lb of azinphosmethyl, 0.5 lb of dicrotophos and phosphamidon, and 1 lb of carbaryl, and [3] for 3 days, 0.25 lb of parathion and 1 lb of carbanolate. One-fourth lb of methyl parathion, 0.5lb of diazinon, endosulfan, malathion, and naled, and 1 lb of TDE provided control inferior to that of 1 lb of DDT for 3 days and no significant control thereafter.
