Effects of an insecticide on German cockroach behavior
… insecticide on various life stages of the German cockroach, Blattella germanica (L.), was conducted. Comparisons between a susceptible laboratory strain (VPI) and a resistant field strain (BP) were made to examine the relationship between physiological resistance and behavioral resistance. The …

A Novel Mouse Model of Asthma Induced by Cockroach
PURPOSE: Cockroach (CR) is an important inhalant allergen and can make a mouse asthma model. However, mechanism underlying the CR-induced mouse model of asthma is not clear and the role of endotoxin contaminated in CR allergen remains controversial. Therefore, we evaluated the role of endotoxin and …

Inheritance of chlordane resistance in the German cockroach, Blattella germanica
… of resistance to chlordane in the German cockroach, Blattell germanica. (L.), was studied by determining the toxicity of chlordane to the following strains of roaches: a) chlordane-resistant and non-resistant strains, b)F₁ and F₂ progeny of reciprocal crosses between two parental strains, …

Application of insecticides to control the German cockroach, Blattella germanica (L.)
Control strategies for the German cockroach, Blattella germanica (L.), are usually based on the application of liquid insecticides in or near infested harborages. Cockroach mortality occurs when they are exposed to insecticide residue by walking on insecticide-treated surfaces. Cockroach walking …

The metabolism of adenosine nucleotides in thoracic muscle mitochondria from the American cockroach
… the thoracic muscle mitochondria of the American cockroach. Myokinase was purified over 100-fold by heat and acid treatment, ammonium sulfate fractionation and column chromatography on G-75 sephadex. Some properties of the enzyme were determined.

Cold-acclimation of the wood cockroach <i>Cryptocercus punctulatus</i> (Scudder) (Dictyoptera: Cryptocercidae)
The general overwintering strategy employed by the woodroach, <i>Cryptocerclls punctulatus</i> (Scudder) appears to be fairly typical among freeze-tolerant insects. In this species, as well as others, heat-labile hemolymph ice nucleating factors induce extracellular ice formation at a high subzero …

T-Regulatory Cells and FLT3-Ligand in the Therapy of Cockroach Antigen-induced Asthma
… (BALB/c), was examined by adoptive transfer into cockroach (a common inner-city allergen)-sensitized and challenged mice. The adoptive transfer of either of the two subtypes of Tregs reversed AHR and airway inflammation. The cells from the spleen had longer-lasting effect than those of lung cells. …
