| Abstract | ||
| Laboratory studies were conducted in A l -Mussaib Technical Callage -Babylon brovence during 2013 to evaluate effect of Paecilomyces fumosoroseus in different concentration ( 10-1 _ 10-6) spore ̸ ml. on controlling some of homoptera insects (Bemisia tbaci ,Aphis gossypii and Ommitissus lybicas ) the results showed: The concentrations of the fungus effected on the rate death stages of non adult and adult stage for all insects . 10 -1 spor ̸ ml. showed high significant effect of others and high rate of death for nymphs and adults for B. tabaci reached 50,71 and 46.72 % respectively also gave high rate of death for nymphs and adults for A. gossypii reached 54.33and 54.00 % respectively also gaves high death for nymphs and adults for O.lypicus reached 55.86 and 53. 61 % respectively . While the concentration 10-6 gave less rate in death for nymphs and adults of B. tabaci reached 34.85 and 23.58 % respectivily and gave less rate in death for nymphs and adults A. gossypii reached 34.51 and 33.89 % respectively gave less rate in death for nymphs and adults O. lybicus reached 39.64 and 38. 55 % respectivily . The death rates of nymphs and adults of B. tbaci , A. gossypii and O. lybicas were increased according to the duration period after treatment , where the rate of death is low after one day and it increased after two days . المقدمة : | ||
