| Abstract | ||||
| Calotropis procera latex treatments against Locusta migratoria were very persuasive due to mortality efficiency and haemolymph contents of treated nymphs. This study showed the impact of five Usher latex doses 10, 20, 30, 40, and 50 µl by topical applications on 3rd, 4th and 5th. The Ld50 values were 10.3, 10.9 and 12.2µl respectively. The effect of latex usher concentration LD50 (12.2 µl) on haemolymph contents, total carbohydrates, total lipids, total protein and cholesterol of 5th nymphal instar were carried out and showed that the haemolymph content of the treated insects was highly affected and all the studied parameters were lower than the control. | ||||
