Abstract
Neem Azal T/S and Neemix preparations of Azadirachta indica A. Juss, and Melia azedarach L. extracts obtained with acetone, ethanole and methanole were investigated on reproductive capacity effect Leptinotarsa decemlineata Say. A. indica preparations and of plant extracts were tasted to be alternative to chemical insecticide to control L. decemlineata. Bioassays to determine the effect of varying concentrations of extracts were used in two different methods leaf dipping and topical application. In leaf dipping method were used 3-5 days old female adults and in topical application methods were used 1-3 days female adults day. In leaf dipping method, five concentrations of extract and only three concentrations of topical application methods were studied. Experiments were carried out using leaf of Solanum tuberosum. As a result, it was determined that the females applied laid less eggs than the control the individuals to which high concentrations were applied were completely sterile and that the hatching ratio off the eggs have been decreased. It was observed that extracts of M. azedarach have no effect on reproductive capacity as A. indica preparations, but the females applied laid less eggs than the control.
