Tests with organo-phosphorus dry sugar baits against houseflies in Israel.

Tests were carried out in rural areas in Israel with various organo-phosphorus dry sugar baits. Malathion 2.5%, diazinon 1% and Dipterex 1% gave equally effective results. Chlorthion 1% and malathion 1% and 2% were used in smaller quantities and were less effective.Dry poisoned baits are considered an important supplementary measure to a rural fly control programme, especially when used as an adjunct to basic sanitation.
