Acute toxicity of commonly used insecticides viz., fipronil, cyantraniliprole, fluxametamide, phenthoate and thiamethoxam were determined against Red pumpkin beetle, Aulacophora foveicollis collected from the unsprayed fields in orchard Tamil Nadu Agricultural University, Coimbatore using filter paper disc bioassay method. Based on LC50 values (ppm) different insecticides, order was found to be...

Mammea siamensis (Miq.) T. Anders. (Calophyllaceae) plants have long been employed as an active integral composition in Thai traditional medicine. Additionally, phenylcoumarins and triterpenes were reported major components phytochemical research. This work explored the various parts of M. siamensis; barks, flowers, twigs, leaves, young leaves; to determine their bioactive compounds. By using G...

Diaphorina citri Kuwayama (Psyllidae: Hemiptera) and Aphis gossypii Glover (Aphididae; are destructive sap-feeding pests of citrus cotton, respectively. This study assessed the toxicity potential indigenous flora Soon valley surrounding salt range (Punjab, Pakistan) against D. A. gossypii. Among acetone extracts 40 plant species, Mentha longifolia (L.) Huds., Melilotus officinalis Pall., Nerium...

Toxicity assessment of nanoparticles, now widespread in our environment, is an important issue. We have focused attention on the carcinogenic potential of copper oxide (CuO) and titanium dioxide (TiO(2)). In experiment 1, a sequential pilot study, the effectiveness of a carcinogenic bioassay featuring intraperitoneal injection (i.p.) of 20 mg 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK)...

This study examined the effects of several factors (metal contents and soil properties) on bacterial bioluminescence activity, seed germination and root/shoot growth of Lactuca in metal-contaminated soils. Each bioassay showed different sensitivities to extractants of soil samples. Average sensitivities of the bioassay were in the following order: root growth > bioluminescence ≥ shoot growth ≥ ...
