| Abstract | ||
| Present study was carried out to evaluated the effectiveness of the oil extract of Citrullus colocynthis and Nigella sativa on the biology of Trogoderma granarium . Results showed that the oil extracts of N . sativa had the best m effect on all insect stages . The mortality rate of eggs reached 80 %, but it reached 73 .33 % in C . colocynthis oil extracts . The mortality rate of larvae reached 23 . 33% in N . sativa but it reached 11.16 % in C. colocynthis oil extract . The mortality rate and developmental periods of pupa were also effected by the extracts , reached 26.66 % in N. sativa and 11.33% in C. colocynthis , The rate developmental periods reached 3.89 days in the N . sativa comparative with controlling treatment reached 5.8 days . The mortality rate of the adult reached 56. 66 % and productivity of female reached 0. 66 eggs / female . but it reached 23.66 % eggs / female in the control | ||
