Site of Pheromone Production in Female Supella longipalpa (Dictyoptera: Blattellidae): Behavioral, Eleetrophysiologieal, and Morphological Evidence
نویسندگان
چکیده
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 contained significantly more sex pheromone than any other tergites. Cuticular pores occur on all tergites, but their density is highest on the lateral margins of the fourth and fifth tergites. Each pore is connected via a long duct to modified epidermal cells, suggesting that these structures are involved in pheromone production and in its release while the female engages in calling behavior.

The Physiological Basis for the Termination of Pheromone-releasing Behaviour in the Female Brown-banded Cockroach, Supella Longipalpa (f.) (dictyoptera: Blattellidae)
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...
متن کاملThe influence of nymphal and adult dietary protein on food intake and reproduction in female brown-banded cockroaches
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...

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...
متن کاملEffect of Different Diets on Lifetime of Brown-Banded Cockroaches, Supella longipalpa (Blattodea: Blattellidae)
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...
