Study of indirect influence of different concentrations of 2,4-D on the behaviour and development of final silkworm stages (Bombyx mori L.) was carried out on three breeds - Hebar 2, Gergana 1, No 371. 25 small groups of individual silkworms - Bombyx mori L. (consisting of 1 to 34 caterpillars in the final stage) were started to be fed on the same day with mulberry leaves soaked in 0.1; 0.01; 0.001 and 0.0001 water solution of 2,4-D. The occurrence of cannibalism was not registered, and neither were any significant exceptions in the consumption of feed contaminated with 2,4-D. The applied treatments of feed with 2,4-D cause the alteration of content of impregnated eggs in a hatch, and 2,4-D solutions of concentrations 0.01 and 0.001 slightly increase the number of dead praepupae and pupae in cocoons.
