The Origins, Evolution, and Phylogeny of the Praying Mantises (Dictyoptera: Mantodea)
The relatively small insect order Mantodea (praying mantises) is comprised of approximately 2,366 described species distributed in 436 genera. Members of the group occupy diverse habitats and are distributed across the globe, though their greatest numbers and diversity are concentrated primarily in …

Aspectos morfológicos, bionômicos e comportamentais de Hiereoblatta cassidea (Eschscholtz, 1822) (Dictyoptera, Blattodea, Blaberidae)
… Hiereoblatta cassidea (Eschscholtz, 1822) (Dictyoptera, Blattodea, Blaberidae), some taxonomic data, some notes ot its behavior, as well as, their inborn responses to the challenge with the environment, are given.

Group formation and dispersal in the German cockroach, Blattella germanica (L.) (Dictyoptera: Blattellidae)
The studies presented here are an effort toward learning about the behavior of small mixed populations of German cockroaches. Of particular interest was the effect of female cockroaches on the behavior of the group, particularly the group formation within a harborage and the dispersal from a …

A morphological study of first-stage nymphs of five Periplaneta species (Dictyoptera: Blattidae)
Adults of Periplaneta americana, P. australasiae, P. brunnea, P. fuliginosa, and P. japonica are well known and have been well described. However, little systematic work has been conducted on the immature stages. There are very few descriptions of the nymphs of any Periplaneta species, and those …

Cold-acclimation of the wood cockroach <i>Cryptocercus punctulatus</i> (Scudder) (Dictyoptera: Cryptocercidae)
… the occurrence of INF's in a fourth order: Dictyoptera. <i>Cryptocercus punctulatus</i> contains hemolymph ice nucleating factors through out the year. In this species, hemolymph serum freezes at -5.5°C all year long and appears to be initiated by a heat-labile proteinacious nucleating …

Inheritance of resistance to selected pyrethroid insecticides in <i>Blattella germanica</i> (Dictyoptera: Blattellidae)
Four insecticides, cypermethrin, fenvalerate, permethrin and phenothrin were employed to study the inheritance of resistance to pyrethroid insecticides in the Seasons strain of <i>Blattella germanica</i>. This resistance was found to be an autosomal, probably monofactorial character, not linked …

The effects of three insecticides on oothecal-bearing German cockroach, Blattella germanica L., (Dictyoptera: Blattellidae), females
German cockroach, Blattella germanica L., females of resistant and non-resistant strains carrying oothecae were exposed to filter paper impregnated with propoxur, malathion, and diazinon. Premature oothecal drop was monitored during the exposure period and for 24 hours thereafter. Determinations of …

An investigation into the physiology of urate pellet excretion by Parcoblatta fulvescens (Saussure and Zehntner) (Dictyoptera: Blattellidae)
Physiological parameters involved in formed urate pellet excretion by the wood cockroach, <i>Parcoblatta fulvescens</i> were investigated. Uric acid excretion by last instar juvenile <i>P. fulvescens</i> was studied first. Food consumption, urate and non-urate pellet excretion patterns show a …

Catabolic substrate utilization patterns: varying humidity and dietary regimens in the American cockroach Periplaneta americana (L.) (Dictyoptera: Blattidae)
Changes in metabolic substrate utilization patterns resulting from exposure to varying humidity and dietary regimens were examined in the adult, male American cockroach. A series of respirometric experiments were conducted to monitor changes in respiratory quotient (RQ), oxygen quotient (QO₂), food …

Effects of an insect growth regulator (hydroprene) on the morphology of genitalia, development and reproduction of the oriental cockroach, Blatta orientalis L. (Dictyoptera: Blattidae)
Hydroprene [ethyl (E,E)-3,7,11-trimethyl-2,4- dodecadienoate], an insect growth regulator (IGR) "or juvenile hormone analog, was applied to substrata where oriental cockroach nymphs, Blatta orientalis, were reared. A detailed study of the morphology of B. orientalis external genitalia indicated …

Exploring the Evolution and Taxonomy of Evaniidae (Hymenoptera), a Charismatic and Enigmatic Family of Insects
… predators within the oothecae of cockroaches (Dictyoptera), and the family follows a largely tropical distribution. Despite myriad fascinating biological attributes (mimicry complexes, wing venation heterogeneity, unexplored biogeographical patterns) the systematics of these wasps has largely …

Phylogeny of the Polyneopterous Insects With Emphasis on Plecoptera: Molecular and Morpological Evidence
… the paraphyly of Polyneoptera, the monophyly of Dictyoptera, sister taxon relationships between Embiidina + Phasmatodea and Dermaptera + Zoraptera, and a relatively basal placement of Plecoptera. The analyses also support a sister taxon relationship between the newly described Mantophasmatodea …
