The vertical distribution of insects was studied in deciduous forests the temperate zone (the center European Russia). During research, 81342 individuals from 10 insect orders (Dermaptera, Blattodea, Hemiptera, Hymenoptera, Coleoptera, Neuroptera, Trichoptera, Lepidoptera, Diptera, Mecoptera) were collected. Lepidoptera and Coleoptera most numerous. total number Diptera higher at an altitude 1....

Helminths can be transmitted to human beings in several ways, but little attention has been given to vector or mechanical transmission of infective forms by insects. The present study surveys the helminth species present in three orders of insects that coexist in proximity with the human environment. A total of 700 insects (54 Blattodea, 275 Diptera, and 371 Hymenoptera) were collected and exam...

Sinolatindia petila gen. n. and sp. n. (Blattodea: Corydiidae: Latindiinae) is reported from Yunnan Province, China. Description, illustrations and a distribution map of the new taxon are provided. Comparisons with the type genus Latindia Stål, 1860 and the genus Homopteroidea Shelford, 1906 are given.

Belminus ferroae (Hemiptera: Reduviidae) was collected from houses in the localities of San Alberto and Santa Catalina in the municipality of Toledo, Department of Norte de Santander, Colombia. Precipitin tests revealed that the main hosts of B. ferroae are insects belonging to the order Blattodea, whose haemolymph serves as food (89.43%). A low rate of haematophagy was indicated on rodents, do...

background : cockroaches are of vital importance medically and hygienically. they are able to contaminate foods and act as vectors of pathogenic agents such as bacteria, protozoa, and parasites to human environment either mechanically or through their digestive system. cockroaches belong to the phylum arthropoda, class insecta, and order blattodea or blattaria. to date, over 4,500 cockroach spe...

American cockroaches, Periplaneta americana (Blattodea: Blattidae) (L.), are common pests of urban environments. Analyzing spatial distribution of P. americana populations in an artificial, outdoor environment provided insight of gene flow among populations collected in central Texas. This information provides a better understanding of how and if populations were segregated, or if there was a s...

Two new genera and four new species of the aphelinid tribe Eutrichosomellini (Chalcidoidea: Aphelinidae: Aphelininae) are described from India. These are Umairia Hayat gen. nov., Zubairia Hayat gen. nov., U. laiba Hayat sp. nov., U. zeera Hayat sp. nov., Z. mirifica Hayat sp. nov., and Eutrichosomella veenakumariae Hayat sp. nov. Two of the species, U. laiba and E. veenakumariae, are reared res...

The structure of the dermapteran hind wings is described and their hind wing folding is compared with other insect taxa with folded wings (i.e. Coleoptera, Hymenoptera and Blattodea). The peculiarities of the dermapteran hind wing folding are pointed out: the wings are unfolded by the cerci, one wing after the other, in a rather slow process. The antagonistic movement, folding the wings, is ach...

We describe the first two Blattodea from early Eocene Palana Formation of Gurha opencast lignite mine, western Rajasthan, India. Although it is not possible to attribute them a precise family, these large wings suggest warm and humid paleoclimate for area at that time.
