The work has been shown the distribution of three species of cockroachs in Karbalaa provience. They were Periplanet americana. Blattella germanica, and Supella supellectilum. Periplaneta americana is speared in Fariha , Hindia, center of Karbala, Al Husseiniya and AL-Horr as 68%,85% , 80% , 86%, 91% respectively.The results were that the effected adult and reconstruction old nymph was 2 g feces / 25 ml hexane, however, the optimum way to attract reconstruction of early nymph is by 2.5 g feces / 25 ml hexane. The percentage of attraction for adults and early and old stage of nymphs from the feces extract each as 93.3%, 63.3%, 86.6%, respectively.
Additionally, the results were determined the effectiveness of pheromone material and found out that it can be effective without proper storage. The attractions rates did not differ between the first day and fifteenth, where it was 18.3, 16.6, respectively, and that the moral decline occurred after the fifteenth day. However, the effectiveness of pheromone extract with proper storage continued for 105 days.In addition, the results indicated that all the insect pheromone launches the roles effectively attracts all gathered whimsical at different rates and the proportions of the adult combination and reconstruction late nymph convergent where indicated no significant differences between them compared to the early ages nymph.Furthermore, the shelter test results demonstrated that the Periplanet americana prefers to gather in shelters made of wood (opposite) compared to other shelters made from wood (fiber), plastic, metal and cardboard.
