Abstract
This present study was aimed to evaluate the effects of some organic extracts for Plantago lanceolata on the mortality percentages of larval stages of Chrysomya albiceps on the attempt to find out the best concentrations of the extracts that could be used in the control of this insect. Ethyle acetate extract gave the best mortality percentage with 65.8 %, then crude extract with 58% and ethanolic extract with 58% ,while hexane extract 32% , the results also showed that the first larval instar was the highest effective with all extracts with mortality rates reached 69.32% , 66.15% , 66% , 40.8% for ethyle acetate ,crude , ethanol and hexane respectively , while the second and third larval instars were lowest mortality percentages . The present study was showed the 75% concentration was the most effective mortalities of the four organic extracts with rates reached 95.5%, 93.3%, 90% and 63.3% respectively, then 50% conce. and 25% conce. , while 5% conce. was the lowest effective with 21.6% , 17.7% , 8.83% and 4.43% , results also showed that pupal weight were reveal proportioned with the organic extracts, and produced some abnormal pupal shapes.
