The ladybird predatos (Coccinella septempunctata L.) was bred by the cross
mating method, which is followed in all international bio – control centers, to
be transformed from the natural local strain into laborators one, which enable
continous pro
duction and collection of predator groups without affecting the
numerical measurements of the most relevant morphological parameters, such
as insect's body length, and the biological traits, such as fertility, predators
efficacy multiplication, longivity, metamorphesis duration, and sex ratio.
