Abstract
Biological insecticide (Bactospeine) and insect growth regulators (Runner 2F) used against tomato fruit worm Heliothis armigera (Hubn) the eggs results showed that effect of biological bactericide (Bactospeine) for all concentrations was little. So hatch percentage remained within its high levels which were (86.66 , 82.33 and 80.66%) when insecticide had been used with concentration (0.5 , 0.75 , and 1.0 g/l) respectively insect growth regulator (Runner 2F) caused decreasing in eggs hatching percentage which were (70.33 , 46.33 and 0.00 %) when insecticides had been used with concentrations ( 0.25 , 0.5 and 0.75 m/l) respectively. "Bactospeine" gave high mortality percentage was 50.09% when eggs treated with 1.0g/l but mortality percentage was less than 41.23% with 0.5 g/l. Also high mortality percentage to young larval reached 91-33% when eggs treated with 0.5 m/l of (Runner 2F). while less mortality percentage was 37-05% when used 0.25 m/l of Runner 2F.
