Studies have revealed that natural contaminations of cockroaches can occur with many pathogens. There are approximately 40 bacteria species, almost 12 species, of parasitic helminthes. The second most common group of vertebrate pathogens. Numerous viruses, protozoa, and fungi affect humans and other vertebrate species. 1989 , Rivault et al. 1994, Baumholtz et al. 1997 , Cochran, 1999, Eggleston and Arruda 2001, Savoldelli and Luciano 2005 ). Often their movement between waste and food materials led to acquire, carry, and mechanically transfer of these pathogens. Cockroaches are suspected or proven carriers of pathogens such as dysentery and cholera. They also carry typhoid fever and other viral diseases like poliomyelitis. The parasitic worms Ascaris, Taenia and Shistosoma are also carried by cockroaches. This can cause severe allergic reactions such as dermatitis and itching. 1990, Savoldelli and Luciano 2005 ). Supella langipalpa also known as S. supellectilium in southwest Iran, was recently a health problem. The species seems to dominate apartments, and is increasingly becoming a hygiene issue ( Vazirianzadeh, et al. 2013 Sharififard et al. 2014 ). This is a tiny cockroach, 10-14mm long. Its pronotum (male) is fairly uniformly dark with lateral edge and does not display the Blatella germanica two-striped pattern. The adult males appear to be very slender with its wing extending beyond the tip of the abdomen. Females grow long wings that expose a large portion of their slim abdomens. Two dark transverse lines of mesonotal or abdominal terga give rise to the common name. (Cochran 1999).

This cockroach species carries a variety of microorganisms ( Le Guyader et al. 1989 ). This cockroach species is known to transmit pathogenic bacteria into urban areas (Rivault, et al. 1994 It also serves as an allergen-source (Eggleston 2001, Savoldelli 2005, Luciano 2006). Le Guyader (et al.) Identified 29 bacterial species in S. longipalpa. 1989 Moving it from one part of the hospital to another increases the chance of bacteria contamination. Some of the species, like Acinetobacter and Pseudomonas can pose dangers for some types of patients ( Le Guyader. 1989 Infestations of cockroaches can be common, especially in areas without ventilation. 1984 Le Guyader et al. 1989 Baumholtz et al. 1997 Phillips and Appel 2010. For the brown-banded to survive and reproduce, it needs less humidity. As Ahwaz City is a warmer area than previously, this may account for the higher distribution of this species.

However, conventional insecticides still serve as the main method of controlling cockroach infestations. There are concerns over possible harmful side effects. In places like restaurants, food preparation, and storage facilities, insecticides are not allowed. The demand for safer insecticide alternatives increases due to restrictions in chemical insecticide applications ( Savoldellis & Suss 2005 Phillips & Appel 2010, ). In many Iranian field-collected cockroach strains, different levels of resistance have been observed to chemical insecticides. Therefore, these insecticides should not be applied and must be stopped (Nasirian (2010). 2006, Nasirian 2010, Ladonni et al. 2013.

Essential oils, as secondary plant compounds responsible for the aromatic characteristics of plants, present the potential alternative to conventional insecticides ( Isman 2000 Omara et al. 2013 Isman 2006 reports that plant essential oils and extracts can be used to combat nematodes, plant pathogens and pests. Isman 2000 recently highlighted the insecticidal, antifungal, and anticancer properties of plant essential oils. They have fumigants, antifeedant and repellent effects as well as inhibiting the reproduction in cockroaches and other insects ( Omara et al. 2013 They could be used in areas where chemical insecticides are prohibited. Chen and colleagues reported that essential oils repel many pests including termites, houseflies, cockroaches and mosquitoes ( Chen et. al. 2002 Numerous studies have demonstrated the toxicity and repellency of essential oils against cockroaches ( Ahmad et al. 1995 Apple et al. 2001 Jang et al. 2005 Thavara et al. 2007 Ferrero et al. 2007 Ling et al. 2009 Tunza et al. 2009 Phillips et al. Phillips and Appel 2010, Zhu et. al. 2012 Manzoor et al. 2012 Omara et al. 2013 Omara and al.

Contact Toxicity. A bioassay procedure developed by WHO (World Health Organization), (1975), was used for determining susceptibility to or resistance to essential oils. Essential oils were prepared using acetone as the solvent (v/v), in concentrations of 2.5% to 5%, 10%, 15%, 25%, 30% and 50%, respectively. Glass jars 600ml were filled with 2.5ml of each concentrate and allowed to dry at room temperatures. Butter was used to coat the inside of the jars' tops. This prevents cockroach movement. Groups of thirty 3rd and 4th nymph instars were anesthetized by chilling and transferred to plastic cups. Following their recovery, the instars were placed into plastic cups and exposed to the surface for a continuous time. A control group was subjected to surface treatment with acetone. The recovery period was 24 hours.

Fumigant Toxicity: Threety three 3rd and fourth Nymphs Instars were placed in 1-lit glass containers with a cotton ball of 1-cm in diameter that had been treated with 50ml essential oil. To prevent direct contact of cockroaches with essential oil, it was injected to the center of each cotton ball by micro sampler. A control group was subjected to cotton balls treated with Acetone. After recovering for 24 hours, the death rate was taken into account.

Repellency Test: With some adjustments, the method used was that of Ferrero (2006) Manzoor (2012). The circular white filter paper No. 1 (Whatman, 15 cm in diameter) was cut into two equal parts. The solvent was Acetone. The first half was used for essential oil solutions, while the second half was untreated. The following five oils were used to test them: 0, 1, 5, 10, 15, 30 and 50% (V/V). The floor of the cylindrical Plexiglas Plexiglas containers was covered with filter paper after solvent extraction. Thirty-three nymphs (3rd, 4th instars), were released to the floor of each jar. After exposure, the distribution of the nymphs over the 24 hour period was calculated. One half of the filter papers was treated with Acetone, while the other was untreated. All experiments were done with four replicates.
