BACKGROUND The brown-banded cockroach, Supella longipalpa, is not as common as the German cockroach in Iran. This species seeks out areas that are very warm most of the time, and prefer warmer area than what German cockroaches prefer. There is relationship between development of instars and diet of cockroaches. The aim of this study was to determine the effect of different diets on biology, lif...

Argentine ants, Linepithema humile, were attacked by their nestmates following contact with a particular prey item, the brown-banded cockroach, Supella longipalpa. Contact with prey, as brief as 2 min, provoked nestmate aggression. Argentine ants contaminated with hydrocarbons extracted from S. longipalpa also released nestmate aggression behavior similar to that released by the whole prey item...

background: the brown-banded cockroach, supella longipalpa , is not as common as the german cockroach in iran. this species seeks out areas that are very warm most of the time, and prefer warmer area than what german cock­roaches pre­fer. there is relationship between development of instars and diet of cockroaches. the aim of this study was to determine the effect of different diets on biology,...

The number of cells and their sizes in the corpus allatum (CA) of adult female Blattella germanica, Supella longipalpa and Diploptera punctata were determined during oocyte maturation. Cell number and size were directly measured in cell suspensions following enzymatic dissociation of freshly excised CA. Cell numbers were verified by total cell counts in whole-mount CA monolayers and by hemocyto...

background: considering to the high distribution of cockroaches as urban pests, the efficacy of different formula­tions of metarhizium anisopliae strain iran 437c were assessed against the brown-banded cockroach, supella longi­palpa f. under laboratory and field conditions. methods: metarhizium anisopliae isolates were screened with immersing adults of the brown-banded cockroachs in aqueous sus...

BACKGROUND The brown-banded cockroach, Supella longipalpa is known as a carrier of pathogenic bacteria in urban environments, but its role is not well documented regarding the carriage of antibiotic-resistant pathogenic bacteria in Iran. The aim of this study was to determine the resistance bacteria isolated from the brown-banded cockroach in Ahvaz, south west of Iran. METHODS Totally 39 cock...

Social insects use a complex of recognition cues when discriminating nestmates from non-nestmate conspecifics. In the Argentine ant, Linepithema humile, recognition cues can be derived from exogenous sources, and L. humile acquires prey-derived hydrocarbons that are used in nestmate discrimination. We studied Argentine ant population-level distinctions in response to external recognition cues. ...

The demography of the brownbanded cockroach, Supella longipalpa (F.) (Blattodea: Blattellidae), was studied based on the age-stage, two-sex life table at 25, 29, and 33 degrees C. Females incubated at the three temperatures produced 11.8, 14.6, and 12.8 oothecae per female, respectively. The life expectancy for a newborn was 157.2, 207.7, and 147.9 d, respectively. The intrinsic rate of increas...

The factors contributing to the termination of calling (pheromone release) in adult female Supellu longipalpa were examined. Calling ceases after mating and does not resume over the duration of the insect’s life. Calling was suppressed and basal oiicyte growth was stimulated by the transient presence of a sperrnatophore, by the implantation of an artificial spermatophore, and by mating with vas...
