Thiocarbohydrazide (TCH) was the most toxic of numerous convulsants tested in houseflies and was as toxic to a DDT-resistant strain as to a susceptible strain. The LD-50 values ranged from 0·3 μ g/fly for injected aqueous TCH to 1 μ g/fly for TCH

Various aqueous ovicidal formulations, some of which pose minimum hazards for higher organisms, are described for use against Aedes aegypti (L.). These ovicides appear to attack mainly layers of the eggshell which resist water permeability, an attack
