| Abstract | ||
| The eleven-spot ladybird Coccinella undecimpunctatata L. is one of the biological control Agent used against many economically important insect pests. The research showed the following data : The ladybird C. undecimpunctata was reared in the laboratory preying upon the alive and frozen black broad bean and cotton aphids .A larva of ladybird were able to develop on these two species complete life cycle and continued to the following generation, their life cycle coincides with the life cycle of the prey, their ability, in both larval and adult stages, to prey on the hosts, and their ability to choose an alternative victim when the numbers of the first prey are small. it has been shown that they attack and feed on twelve other aphids, as well as the eggs and larvae of the slugworm and the larvae of the diamondback moth, The larva of ladybug consumes about 400 medium-sized insects during its development to the pupal stage; while as an adult, it consumes 300 insects before laying eggs. Overall, it consumes 5000 insects during its lifetime, as the appetite of the ladybirds and their high reproductive capacity makes them consume their prey quickly. The importance of ladybugs comes from their presence throughout the year, their coincidence with the presence of aphid species. and that their numbers constituted 50% of the numbers of other predators, which reduced the population density of aphids in the field to the level at which the use of chemical pesticides was dispensed with. | ||
