abstract indian meal moth, plodia interpunctella hübner (pyralidae) is one of the most important stored-product insects that are controlled by fumigants. however, the use of plant essential oils and their constituents may have the advantage over conventional fumigants in terms of low mammalian toxicity and can be used as alternatives to conventional fumigants. therefore, in this research, repel...

indian meal moth, plodia interpunctella hubner is one of the most important stored-product insects that are controlled by fumigants. however, the use of plant essential oils and their constituents may have the advantage over conventional fumigants in terms of low mammalian toxicity and can be used as alternatives to conventional fumigants. therefore, in this research, repellent activity of 18 p...

The acute toxicity of photoactivated anthracene and pyrene to the glochidial larvae of the paper pondshell (Utterbackia imbecillis) was characterized in the laboratory using two sets of experiments. Acute toxicity tests designed to determine the overall sensitivity of glochidia to anthracene and pyrene were conducted under simulated sunlight (ultraviolet [UV]-A = 70+/-0.5 microW/cm2 [mean +/- s...

The acute toxicity of Roundup, a glyphosate herbicide, to Nile tilapia, Oreochromis niloticus, was investigated with emphasis on histopathological effects. The values of 24-h, 48-h, 72-h and 96-h LC50 for young tilapia were 17.5, 17.1, 16.9 and 16.8 ppm, respectively, and those for adult tilapia were 46.9, 44.4, 40.0 and 36.8 ppm, respectively. They indicated that adult fish were more tolerant ...

background previous studies have shown that shallomin, one of the active constituents of persian shallot, has a broad range of antimicrobial properties. objectives the safety of shallomin must be established before it can be used in clinical applications. therefore, the aim of the present study was to evaluate the acute toxic effects of shallomin and to estimate its lethal dose low (ldlo) value...

chlorpyrifos is one of the organophosphate pesticides that are commonly used to control insects in domestic activities and many agricultural farms that are located in close to water sources. hence, the present study, investigate the lethal toxicity of this pesticide. in this study, fish were treated in groups of 21 with different concentrations of chlorpyrifos (aria brand with active ingredient...

Lethal effects of zinc sulphate (ZnSO4.H2O), a widespread environmental pollutant was evaluated following exposure at different concentrations of the toxicant to Tilapia species, Oreochromis niloticus based on toxicity index of 96 hrs LC50 values. The obtained results were analyzed by the Finney’s Probit Analysis LC50 Method and 96 hrs LC50 value for Oreochromis niloticus was found to be 72.431...

Recently, due to active development of the pharmaceutical industry, an acute problem environmental pollution with synthetic biologically compounds has arisen. Benzimidazole cycle is one most frequently encountered pharmacophores in drugs. Substances containing even microquantities benzimidazole have a toxic effect on living systems. Besides, being alien nature, benzimidazoles are not included m...

the toxicity of 7 herbicides to the three cyanobacteria was tested in this work. the results indicated that: (1) there was a highly significant relationship between dried weight or chlorophyll-a and od680nm for tested cyanobacteria; (2) the toxicity of the tested herbicides with the order from high to low was: photosynthesis-inhibiting > accase inhibitor > protox inhibiting herbicides; (3) the ...
