Due to the importance of insects present in storages, which cause a lot damage stored materials (cereals, seeds, dates and other materials), current study was proposed determine species spread Iraq. It showed 31 belonging 16 genera under eight families two orders. The specimens were collected from several storage spaces at regions Tribolium castaneum (Herbst, 1797) most abundant population comp...

ENETIC analysis of a variety of traits in populations of several species has revealed a similar pattern for many traits which are important components of fitness. In general such characters have intermediate optima, and prolonged artificial selection for extreme expression leads to a reduction in fitness. LERNER (1954, 1958) has postulated that one possible mechanism for natural selection in fa...
