BACKGROUND Essential oils, as secondary plant compounds, present a safer alternative to conventional insecticides in insect control programs. So five essential oils including eucalyptus, mint, yarrow, oregano and rosemary oils were evaluated against the brown-banded cockroach Supella longipalpa. METHODS Evaluation was done against the 3rd and 4th instar nymphs using three bioassay methods; co...

BACKGROUND The brown-banded cockroach Supella longipalpa (F.) as a mechanical vector of pathogens and source of allergens has recently become widespread in the city of Ahvaz, southwestern Iran. OBJECTIVES This research was done to evaluate the efficacy of a dust-formulation of Metarhizium anisopliae isolate IRAN 437C, as a common entomopathogenous fungus, against S. longipalpa. MATERIALS AN...

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 suspe...

Female brown-banded cockroaches, Supella longipalpa (F.) (Dictyoptera : Blattellidae), failed to elevate consumption rates when fed a 5~o protein diet compared with females fed either 25~o protein or commercial rat food. Adult performance was directly influenced by dietary protein level: Females fed 65 ~o protein died rapidly, while in females fed 5 ~o protein feeding and reproductive rates wer...

b a ckground: 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 bacte- ria 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. m e t hods: totally ...

BACKGROUND Cockroaches are of vital importance medically and hygienically as they can disperse human pathogenic agents and are especially responsible for food contamination and spreading of food borne pathogens. In this study, part of mtDNA-COI gene of five common pest cockroaches was tested for diagnostic and phylogenetic purposes. METHODS We have described barcode region of mtDNA-COI gene o...

The site of sex pheromone production in female Supella longipalpa (F.) was localized to the fourth and fifth abdominal tergites. Behavioral assays of males with hexane extracts of various female body parts showed that these tergites were significantly more attractive than any other region of the body. Both behavioral and electroantennogram assays confirmed that the fourth and fifth tergites con...

Development and activity of the corpora allata (CA) were investigated in adult female Blattella germanica and Supella longipalpa. These two cockroach species differ in their reproductive modes, with relatively uninterrupted cycles of oocyte development in S. longipalpa and discrete patterns of oocyte development which are interrupted by pregnancy in B. germmica. During ovarian cycles in both co...
