Cross resistance to organophosphorus compounds in malathion- and diazinon- resistant strains of the German cockroach
… to malathion and the other resistant to diazinon. Comparison of this data with similar data for a normal susceptible strain of the same species reveals that development of resistance to malathion in this species is highly specific imparting no effective cross resistance to any of the …

The effect of the sheep dip pesticide diazinon on behavioural and molecular markers in the freshwater shrimp Gammarus pulex
… effects of the organophosphorothioate pesticide diazinon, its metabolite diazinon oxon and diazinon in a commercial formulation on the freshwater amphipod Gammarus pulex. It was found that diazinon in the commercial formulation was significantly more toxic to G. pulex than diazinon oxon, which in …

The effect of eight tensides on the toxicity of diazinon topically applied to the male German cockroach
The effect of 8 tensides on the toxicity of diazinon were investigated by means of topical dose applications to male adult German cockroaches, Blattella germanica (L.). Other diazinon formulations were evaluated for comparison. These were Diazinon 4E, Diazinon 4E plus Igepal CO-630, Oiazinon 4E …

The Effects of Diazinon on the Growth Rates and Population Dynamics of Planktonic Algae and the Possible Uptake By Two Algal Species
… effects of various concentrations of formulation Diazinon on unialgal growth rates and freshwater population dynamics as well as the possible uptake by algal cells were studied. Comparison of standard errors from mean growth rates showed no significant inhibitory response by Chlorella …

The study and optimization of the Enzyme Inhibition Bioassay 96 for the detection of organophosphate and carbamate compounds
… were the pesticides carbaryl, chlorpyrifos, diazinon, dichlorvos, and parathion. The pesticides chlorpyrifos, diazinon, and parathion are organophosphorothioates, which are organophosphates with a P=S bond, and when these compounds are oxidized the compounds are converted to their oxygen …

Biochemical effects of organophosphorous compounds on cultured rat and human cardiomyocyte-like cells
… (PSP), two organophosphorothioate insecticides (diazinon and chlorpyrifos), and their acutely toxic metabolites (diazoxon and chlorpyrifos oxon) on rat H9c2 and human cardiomyocyte-like cells. The rat embryonic H9c2 myoblast cell line, which has the ability to differentiate into a cardiac muscle …

Examining the impacts of pesticide exposure on the survivorship and development of the Great Basin Spadefoot (Spea intermontana) and the Pacific Treefrog (Pseudacris regilla) in a laboratory environment
… formulations of endosulfan, azinphos-methyl and diazinon were tested alone and in combination. Embryos of the Great Basin Spadefoot (Spea intermontana and Pacific Treefrog (Pseudacris regilla) were collected from reference sites in the South Okanagan of BC, and transported to a federal government …

Sublethal vapor-induced responses of the German cockroach to commercial pesticide formulations
… blanks. Exposure of cockroaches to the vapors of diazinon, malathion, and cyfluthrin indicated that the class of pesticide can also influence the dispersal response. Strain differences were found in experiments with the propoxur formulations, their blanks, malathion, and cyfluthrin. Slow dispersal …
