Abstract
Carbohydrates, lipids and proteins contents were evaluated in 5th larval instar haemolymph of Spodoptera littoralis (Boisd.) that treated with four isolates of entomopathogenic fungi Beauveria bassiana, Metarhizium anisopliae, Paecilomyces lilacinus and Lecanicillium antillanum at 1st, 2nd, 3rd and 4th days. Generally, data in present work cleared that, there was significant decrease in haemolymph carbohydrates of larvae injected with the entomopathogenic fungi in the three time intervals (1st, 2ndand 3rd) under investigation compared to control. The concentration level of protein content of larvae injected with the fungi significantly increased as compared with control insects in (1st) day, then there is no significant change in the content after 2nd and 3rd day except increasing was noticed with the two fungi (B. bassiana and L. antillanum).There were significant increases of carbohydrates and protein contents observed in the last day (4th day) due to effect of fungal infection. Significant increases of lipid content was noticed in the 5thinstar cotton leaf worm larvae inoculated with the four tested fungi from 1stto 4th day. The overall results indicated that total S. littoralis larvae proteins, carbohydrates and lipids contents vary significantly during infection of the tested fungi at the four time intervals (1st, 2nd 3rdand4th days) and this tend to  dramatically changes in the composition of haemolymph, thus abnormal growth and development of insect caused.
