Abstract
Effects of Dimilin on adults and eggs of Agelastica alni L. (Coleopt., Chrysomelidae)
In consequence of treating adults ofA. alni with Dimilin the median number of egg clusters per female decreased about by a half. The absolute number of eggs was not affected. On the contrary the number of fertilized eggs as well as the number of hatched larvae decreased considerably. In the controlbreedings there were no differences between the quote of fertilized eggs and that of hatched eggs, but the treatment of adults with Dimilin resulted in a great difference between these quotes. The behaviour of male and female adults did'nt show changes. The eggs were susceptible to Dimilin, the young eggs more than the elder ones.
