This study aims to know the types of insects belonging to the Sphaeroceridae family. During this study, one species registered for this family for the first time to Iraq (New genus and species). It is using two methods of killing are injurious machine (knife) and toxic substance (strychnine). Four areas within Karbala governorate studied and identified to know their spread and time of presence on the body during the stages of decomposition. During this experiment, the bodies of dogs used to identify types of insects attracted to the body during four seasons. The results indicated the presence of the species Pullimosina heteroneura (Haliday, 1836) in the first three stages of decomposing the bodies, but in different proportions and the highest was in the wet decomposition of the body for the spring and autumn seasons.
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 .
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
