  The present study investigated the probable responsible reasons for non-response the B. germanica to permethrin only in World Health Organization glass jar method after insecticide spraying control failure with pyrethroid insecticide groups in Islamic Republic of Iran. Eleven German cockroach strains were collected from field populations of nine infested kitchen student dormitories and two infested hospitals after insecticide spraying control failure with pyrethroid insecticide groups in Iran. The current study, in World Health Organization glass jar and knock down methods conducted on newly emerged adult males.All feral strains, with various levels of resistance to pyrethroids, in World Health Organization glass jar method at 400 min (6 h) time exposures, was not observed mortality, while the susceptible strain was observed 100% mortality in 25 min time exposures. Susceptible strain at LT50 after assessing on mortality data from the replicates by probit analysis in World Health Organization glass jar method was 15.3 min. In this study, all feral strains in World Health Organization glass jar method after 400 min (6 h) time exposures, was not observed mortality, that showed these strains very high-level resistance to permethrin. In the knock down method, the resistance ratios were 3.6 to 26.1-folds compare with the susceptible reference strain. In a comparison, among this study and previous studies resistance ratios of 8.6 to 17.7-folds for permethrin in topical application, indicated that German cockroach have had under pressure spraying. German cockroach have had in vicinity to pyrethroid insecticides especially permethrin in these locations in long period for non-responding to permethrin insecticide only in World Health Organization glass jar method, and the field evident confirm this subject.

  In this study whole blood cholinesterase activities of the agriculture and hygiene spray workers exposed to organophosphorus and carbamate compounds from different parts of Tehran Province in Iran were determined. Lovi Bond method was used in three stages including prepare the questionnaires about spray worker body health conditions, taking their blood samples before and after working and their insight to insecticides and prepare the required solutions. Results showed that no any changes were observed in the 50% of the spray worker blood cholinesterase activity after working. In the 32.4% of them, cholinesterase activity has decreased up to extensive poisoning and in the 17.6% of them cholinesterase activity was much decreased at the end of an acute or severe poisoning, whereas in testifier workers less than 5.9% of them cholinesterase activity was decreased and in the 94.1% of testifier workers cholinesterase activity was normal. Analysis of the data demonstrated that no significant relationship between spray worker blood cholinesterase activity, age groups, history of working, knowledge, cigarette smoking, history of toxicity and their responsibilities were observed. The measurement of pre-exposure cholinesterase values is essential for comparison of the values after pesticide application.

  The German cockroach is an important household insect pest worldwide and acts as a mechanical vector and reservoir for pathogenic agents. The aim of this study was to examine the basic laboratory toxicity of Blattella germanica to spinosad. The M, T, A22, AZAR4, BOOSTAN7 and ABAN21 strains were collected from field populations of six infested kitchen student dormitories and the SAMAN strain was collected from a residential area after insecticide spraying control failure in Tehran, Iran. Technical grade spinosad was delivered in 0.5 μL acetone to the first abdominal sternum of briefly CO2-anesthetize adult male cockroaches by topical application bioassay. Treated males monitored for mortality. Mortality data from the replicates was assessed by probit analysis. The average LD50 of susceptible strain was 494.3, 148.8 and 55.1 ng per insect after 24, 48 and 72 h, respectively. The LD50 of spinosad decreased with time in the field population strains. All German cockroach strains showed a similar susceptibility or lower tolerance (1.6-folds) for spinosad compared with the susceptible laboratory strain and the steep slopes of dose-response curves indicated that the field population of these German cockroach strains was homogenous in response to spinosad. These results indicated that the spinosad was relatively slow-acting in topical application bioassay, with LD50 values decreasing until 72 h and becoming stable thereafter. The effectiveness of spinosad against susceptible and the field population German cockroach strains in laboratory condition showed that spinosad probably could be useful for the control of the German cockroach.

  The duration of fipronil WHO glass jar method toxicity against twelve strains of feral German cockroaches, Blattella germanica (L.), was determined. In the WHO glass jar bioassay, the average LT50 of susceptible strain was 16.4,14.3,12.4 and 11.3 exposure minutes after 24,48,72 and 96 h, respectively and the average LT95 was 20.3,19.9,19.5 and 19.1 exposure minutes after 24,48,72 and 96 h, respectively. As with the susceptible reference strain, where LT50 was halved from 24 to 96 h, the LT50 of fipronil decreased with time in the feral German cockroach strains. LT50 varied > 8-folds from 16.2 to 24.7 exposure min at 24 h, 8.4 folds from 14.4 to 22.8 min at 48 h and almost 8.8 folds from 12.5 to 21.3 exposure minutes at 72 h. At the end of the bioassay at 96 h, LT50 varied from 11.6 to 19.7 exposure minutes, which is 1.0 and 1.7 folds exposure min higher than the standard susceptible value of fipronil. All German cockroach strains showed a similar susceptibility or very low tolerance (1.5 to 1.7 folds) to fipronil compared with the susceptible laboratory strain and the steep slopes of time exposure-mortality curves indicated that the feral German cockroach strains was homogenous in time exposures to fipronil. These results indicate that the fipronil was relatively slow-acting in WHO glass jar method bioassay, with LT50 values decreasing until 96 h and becoming stable thereafter.

  The duration of fipronil topical application toxicity of twelve strains of German cockroaches, Blattella germanica (L.), was determined. The Saman strain was collected in 2002, from infested Habitable Convened and the Bustan-7, Bustan-8, Bustan-10, Kouye-Pezeshky, Shahmorady, Zanjan and Kouye-Tehran strains were collected in 2001, from different infested student dormitories and the Fayyazbaghesh, Mogtameh and Kouye-Dokhteran strains were collected in 1997 from two infested hospitals and one student dormitory, respectively in Tehran, Iran. In the topical application bioassay, the average LD50 of susceptible strain was 1.8, 1.3 and 0.96 ng per insect after 24, 48 and 72 h, respectively and the average LD95 was 3.4, 2.6 and 2.2 ng per insect after 24, 48 and 72 h, respectively. As with the susceptible reference strain, where LD50 was halved from 24 to 72 h, the LD50 of fipronil decreased with time in the field populations. LD50 varied > 3-fold from 1.2 to 3.6 ng per insect at 24 h and almost 2.5-fold from 1.2 to 3.0 ng per insect at 48 h. At the end of the bioassay at 72 h, LD50 varied from 0.94 to 2.5 ng per insect, which is 1.6- and 2.6-fold higher than the standard susceptible value of fipronil and the steep slopes of dose-response curves indicated that the field population of these German cockroach strains was homogenous in response to fipronil. All German cockroach strains showed a similar susceptibility or lower tolerance (1.5 to 2.6-folds) for fipronil compared with the susceptible laboratory strain and the steep slopes of dose-response curves indicated that the field population of these German cockroach strains was homogenous in response to fipronil. These results indicate that the fipronil was relatively slow-acting in topical application bioassay, with LD50 values decreasing until 72 h and becoming stable thereafter.
