The insecticidal properties of two fibre‐reactive organophosphorus esters , O‐ ethyl ‐S‐n‐ propyl ‐O‐ (4‐ (2‐(3‐ vinylsulphonylpropionyl) oxyethyl)‐thiophenyl) phosphorothionothiolate and O‐ ethyl ‐S‐n‐ propyl ‐O‐ (4‐(2‐(3‐vinylsulphonylpropionyl) oxyethyl)‐thiophenyl)phosphorothiolate, have been determined against a number of keratin‐digesting insects. Both compounds were effective against the more common textile pests at relatively low application levels; however, considerably higher levels were required to control the feeding damage due to Hoffmannophila pseudospretella. Generally, the insecticidal activity of the phosphorothiolate was greater than the activity of the phosphorothionothiolate; however, this was offset by the greater susceptibility of the phosphorothiolate to hydrolysis during application from a dyebath. The application of these compounds during dyeing and other textile processes was examined.
