Control of American Cockroaches (Dictyoptera: Blattidae) in Sewers
Journal of Medical Entomology, 1991Baits, dusts, and aqueous sprays were applied to sewer shafts to control American cockroaches, Periplaneta americana (L). Boric acid and hydramethylnon baits failed to provide consistent control because of problems with mold on the baits and because large populations of cockroaches depleted the bait.

The adipokinetic hormone of Mantodea in comparison to other Dictyoptera
Archives of Insect Biochemistry and Physiology, 2017AbstractSix species of the order Mantodea (praying mantises) are investigated for the presence and sequence of putative adipokinetic hormones (AKHs). The selected species span a wide evolutionary range of various families and subfamilies of the clade Mantodea.

Ethology Ecology & Evolution, 1991
The cockroach Blattella germanica hosts symbiotic bacteria in both the fat body and the ovary. The transmission of symbionts from one generation to the next is of the transovarial type. In 2nd-instar nymphs, bacteria leave the intraovaric bacteriocytes and reach the space between the follicular epithelium and the oocyte.

Toxicity of Abamectin to Cockroaches (Dictyoptera: Blattellidae, Blattidae)
Journal of Economic Entomology, 1991Abamectin was fed to German cockroaches, Blattella germanica (L.), in non-choice tests. LT50s and LC50s were estimated by probit analysis. The LT50s for the German cockroach ranged from 4.4 to 1.7 d for males, from 9.0 to 2.4 d for females, and from 4.4 to 1.6 d for nymphs for bait concentrations of abamectin between 0.0025 and 0.0500%.

Biology of Symploce pallens (Dictyoptera: Blattellidae).
Journal of economic entomology, 2010Here, we describe the biology of a relatively new pest cockroach species in Southeast Asia, Symploce pallens (Stephens) (Dictyoptera: Blattellidae). S. pallens collected from Penang Island, Malaysia, were used for the biological parameter studies and were observed for molting and reproduction events.

A comparative study of the hypopharynx in Dictyoptera (Insecta)
Zoologischer Anzeiger - A Journal of Comparative Zoology, 2013Abstract The exoskeletal morphology of the hypopharynx is documented for and compared between nine species of Dictyoptera that represent most of its principal lineages (seven cockroaches, one mantodean, and the ‘basal’ termite Mastotermes darwiniensis ).

Histology and physiology of the mandibular glands in Dictyoptera
Journal of Entomology Series A, General Entomology, 1972SYNOPSIS An account is given of the mandibular glands in five families of Mantodea and in two families of Blattodea. The enzyme content of the gland secretion of Sphodromantis lineola is analysed, and the function of the secretion discussed.
