Environmental Study of Effect of Some Plants Extracts on Culex pipiens mosquitoes

Background 
 In the nature there are many plants that play important roles to control mosquitoes, but some of these can increased their effect after mixed with another plant. For that, this study aimed know mixture two types different on Culex pipiens mosquitoes in larva stages and process hatching eggs. Materials methods research parsley water extract (Petroselinum crispum) mosses (Funaria sp.) have been taken as ratio (1:1) using concentrations (4.5, 3.5, 2.5, 1.5, 0.5) mg/l from it.
 Results The results show percentage mortalities for C. were (89, 72, 55, 42, 39)%, 62, 56, 36, 38)%, (75, 67, 54, 46, 26)% (77, 65, 63, 40)% LC50 (1.8, 2, 2.3, 1.3) first, second, third fourth stage respectively. While eggs exposed extracts (31, 43, 71, 83)% (3.2) mg/l. haven’t shown a significant differentiation among stages, they level probability (0.05), also positive correlation coefficient negative Conclusion
 be killed low concentration mortality increases extract, prevented hatching.
