Abstract | ||
This study conducted to evaluate the efficiency of Ethanolic extracts of fruits of Melia azedarach L and Citrullus colocynthis on some biological aspects of two red spots mite Tetranychus urticae. The results showed positive correlation between mortality concentrations percentages in first nymph instars after one day of treatment , So the highest mortality percentages (74.8 and 89,8) %recorded when treated with 100% extract concentration of M. azedarach L and C. colocynthis. Also the results showed inverse correlation between the concentrations and adult emergency percentages ( 8.7 and 1.0) % after treated first nymph instars with 100% extract concentration of M. azedarach L and C. colocynthis respectively. Moreover the results showed malformation in adults which emergence from trated nymph , and the adults malformed percentages increased with extracts concentrations increased and its different significantly than control . In addition the results showed that the extracts of M. azedarach L was more efficiency in almost biological aspects which studied in this pest compared with extract of C. colocynthis . | ||
