It was recommended to use chemical insecticides against aphids in wheat fields. Since wheat is addable food for human and its livestock and to avoid any chemical...

In this study, the numerical phenetic method was applied on Coccinella undecimpunctata Linnaeus and its 13 aberrations. These aberrations were collected from 10 localities from Lower and Upper Egypt. The morphometric measures were used to obtain a phenogram representative of phenetic similarities and affinities among the all morphs. RAPD fingerprint profiles were generated by using five random primers on genomic DNA to characterize all the aberrations and to determine their phenetic relationships as well as to investigate the molecular markers among the aberrations genotypes. The genetic...
