| Abstract: | In Lymnea stagnalis (F 1 generation) carbaryl weakly disturbs the growth of the shell with 2 ppm, strongly with 4 ppm (lethal concentration for the young snails).The shell growth inhibition by lindane is correlated with the concentration (1 & 2 ppm). The degree of intoxication of parents is very important. The two insecticides play a complex part in the mineralization of the shell. The effects of lindane on growth and mineralization of the shell have a reversible character. |
