In laboratory tests against the adults of the apple maggot, Rhagoletis pomonella (Walsh) (Diptera: Trypetidae), seven insecticides were rated, in descending order, as follows: DiazinonĀ®, GuthionĀ®, malathion, SevinĀ®, DDT, calcium arsenate, and lead arsenate. Calcium arsenate used with Bordeaux mixture was as effective as Sevin, and the addition of nicotine sulphate increased the effectiveness to that of malathion. A mixture of lead arsenate and DDT was more effective than either used alone. Some loss of toxicity occurred when Diazinon or Sevin was combined with the fungicides glyodin, captan, dichlone, and Bordeaux mixture. Lead arsenate increased slightly in effectiveness when combined with captan but not with glyodin or dichlone.

Diazinon is O,O-diethyl O-(2-isopropyl-6-methyl-4-pyrimidyl) thiophosphate

Guthion is O,O-dimethyl S-4-oxo-1,2,3-benzotrillzin-3-(4H)- ylmethyl phosphorodithioate Sevin = 1-naphthl N-rnethylcarbamate

Sevin = I-naphthl N-rnethylcarrbamate
