Abstract
A series of laboratary experiments carried in Biological Control Depattment – Technical Collage / Al – Mussiab in Babylon Gov. during the period 2008 / 2009 to determine the ability of the predator C. undecimpunctata to feed on artificial foods , the results showed :- The larvae feed on a mixture nutrition of children (Dialack) and mixture of sheep liver had died several days after the beginning of the feeding and had faild to reach to the next instar and was not be able to reach into the pupal instar , while all those larvae feed on either a mixture of sheep liver with quial eggs or quial eggs mix. had completed their life naturally . the longest duration of the 1st , 2nd , 3rd and 4th larval stage were 2.83 ,3.17 , 3.67 and 4.17 days respectivily when feeding on quial eggs mix . As for the pupal stage was completed the period of its development during 6.67 and 5.00 days when feed on mixture of sheep liver and quial eggs respectivily , although the average length of life of adult predator C. undecimpunctata that had been feed on a mixture quial eggs was increased significantly and reached to 34 days old which was different from the other treatment. While the shortest duration of adult reached 27.33 days when it comming from lavae stages feed on sheep liver .
