Abstract
Seven treatments of organic (peanut residue) incubated and non-incubated
and chemical fertilizers (urea and potassium sulphate) were evaluated on the fertility
of wingless females of Aphis craccivora Koch. Bean plants cultivated in loamy soil
was treated with different fertilizers and the fecundity of A. craccivora was estimated 7
and 10 days after treatment. Obtained results indicate that the organic fertilizers when
incubated became more effective than the non-incubated ones. led to increase the
pest population on bean plants. While by using organic and chemical fertilizers
separately. the fecundity of the pest decreased. while their mixture increased the
aphid infestation significantly.
