The effect of commonly used acaricides (amitraz, cypermethrin, deltamethrin, fenvalerate, and flumethrin) on the eggs of Rhipicephalus (Boophilus) microplus collected from Ludhiana, Punjab, was evaluated by egg hatch assay (EHA). The regression graph of probit hatchability and per cent inhibition of hatching (IH%) of eggs was plotted against log values of concentration of various acaricides. Al...

This study investigated alternative in-field chemical controls against Bactrocera tryoni (Froggatt). Bioassay 1 tested the mortality of adults exposed to fruit and filter paper dipped in insecticide, and the topical application of insecticide to adults/fruit. Bioassay 2 measured the mortality of adults permitted to oviposit on fruit dipped in insecticide and aged 0, 1, 3, or 5 days, plus the pr...

A sensitive and effective method for the simultaneous quantitative determination of procymidone, pyridaben and beta-cypermethrin residues in tea solutions was developed and validated using a gas chromatograph (GC) equipped with an electron capture detector (ECD). The analysis of the three pesticides in tea solutions involved extraction with petroleum ether-ethyl acetate (3:1, v/v), cleanup usin...

Chlorpyrifos, lambda-cyhalothrin, cypermethrin, spinosad and buprofezin were tested against the second instar larvae and adults (except buprofezin) of the green lacewing, Chrysoperla carnea. The results showed that chlorpyrifos was more toxic to second instar larvae than lambda-cyhalothrin, cypermethrin, spinosad and buprofezin with LC50 values of 1.78, 8.81, 26.9, 294.36 and 997.05 ppm respect...

Nesidiocoris tenuis (Reuter) (Hemiptera: Miridae) is an effective predator of multiple pests of vegetable crops, such as thrips, mites, aphids, whiteflies, leafminers. It is mass-reared and released for augmentative biocontrol programs mainly aimed at controlling whiteflies and Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) in greenhouses and open field. We evaluated the lethal and subletha...

This study was carried out to investigate blood biochemical alteration in albino rats after cypermethrin treatment. Nitrogen contents of blood in the albino rats have been influenced by the amount of cypermethrin used for toxicity in the acute (1d) and sub chronic (7,14and21days) treatment in the present investigation. The free amino acid, total protein, urea, urea nitrogen, uric acid and creat...

Pesticide residue analysis in citrus oils is very important for their quality and marketing. This study assessed the reliability and sensitivity of enzyme-linked immunosorbent assays (ELISA) for simazine and cypermethrin screening in orange oil. Simazine was analyzed after extraction of the oil with methanolic phosphate buffer with a limit of quantitation (LOQ) of 40 microg/L for 1-fold and app...

To determine cypermethrin and permethrin in agricultural products, a competitive enzyme-linked immunosorbent assay (ELISA) method was employed. The matrix interferences were minimized by direct dilution of the extracts. No further cleanup was needed. A minimum matrix effect with a 1:10 dilution of white wine for cypermethrin and a 1:200 dilution of red and white wines, fruits, and vegetables fo...

Toxicity of cypermethrin insecticide was evaluated in the liver of 16-day old chick embryo following administration of a single sub-lethal dose of cypermethrin into the eggs on day ‘0’ of incubation. The biochemical analysis of the liver revealed that the activities of aspartate aminotransferase, alanine aminotransferase and lactate dehydrogenase were significantly increased. The activities of ...

Alpha-cypermethrin, which is a synthetic pyrethroid pesticide and potential toxic pollutant, contaminating aquatic ecosystems was investigated in the present study for acute toxicity. Nile tilapia (Oreochromis niloticus) adults were selected for the bioassay experiments. The experiments were repeated three times and the 96-h LC50 value was determined for the adults. The static test method of ac...
