Chemical pesticides are used in Iraq in fairly large quantities in the treatment of the aquatic environment for the purpose of disposal of some pests. Pesticides are used annually to control the water roles of the mosquito insect such as Abate or Temephos.therefore The aim of the present study is the life tables to water flea Daphnia magna under the effect of pesticide Abate (Temephose ) 4% Emolsion Concentration utilized in the aquatic environment against Mosquito larvae As well as , noticing the effects five concentrations (0.25 , 0.5 , 0.75 , 1, 1.25 ) µg/L on the reproductivity of the water flea Daphnia magna in series of laboratory experiments conducted under different environmental conditions such as ( present of O2 , absent of O2 with suspended particles ( Bentonite & Clay).
the results of Abate treatment at a period of partial exposure showed reduction on number of broods and the juveniles number . And using of the insecticide Abate lead to reduce in the number of brood and the juveniles number for F1 individuals in all cases of treatments (absent of oxygen , present of oxygen , addition of some suspension materials ). These results effected on the values of net replacement rate (RO) and the intrinsic rate of increase( rm) which reduced in all uses treatments as a result of the use of Abate that leaded to defect in the growth of Daphnia´s population and this effect transported to the next generations .
