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...

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...

The male genital sclerites of cockroaches of genus Muzoa Hebard 1921 are described for first time and the new species Muzoa curtalata sp. n. is described and ilustrated. A dichotomous key to identify the species of genus Muzoa is given.

Neurogenetic and lesion studies have identified regions of the insect brain that can modulate and direct locomotion. Activities of these neurons have now been recorded in cockroaches during walking.

Although several insect orders have been deeply studied in plant–animal interactions (e.g. pollination) cockroaches traditionally ignored taxonomic and ecological studies. However, they could be playing a role the reproduction of plants. To date, 8 plant species use as pollination agent. In our study, we reviewed 2865 records from citizen science platforms own data Iberian Peninsula to find flo...

Glucose-averse (Glu/Glu) male German cockroaches, Blattella germanica, rejected brief exposures to glucose solutions despite food deprivation so extreme as to cause high mortality. In the 24-h period following 5 days of food deprivation, both Glu/Glu and wild-type (+/+) were given a continuous source of 1 M glucose solution. Although Glu/Glu visited the solution as frequently as +/ + , feeding ...

1. The amount of regenerating limb tissue does not control the length of molting delay in cockroaches; rather, a programmed delay associated with each autotomy level and segment allows an appropriate delay for accomplishing the necessary regeneration. 2. Delay of molting is accomplished by inhibiting ecdysiotropin release. 3. Each regenerating limb produces a delay independent of other regenera...
