The experiment was conducted in local field conditions of Dera Ghazi Khan during the 2021 Kharif season on three different sites. core objective this is to manage Jassid cotton crop a major pest. Five insecticides Dinotefuran, Thiamethoxam, Nitenpyram, Dimethoate and clothianidin were evaluated at recommended doses. treatments laid out randomized complete block designs with replications. Data r...

With their application as seed coatings, the use of neonicotinoid insecticides increased dramatically during the last decade. They are now frequently detected in aquatic ecosystems at concentrations susceptible to harm aquatic invertebrates at individual and population levels. This study intent was to document surface runoff and subsurface tile drain losses of two common neonicotinoids (thiamet...

Knowledge on side effects of pesticides on non-target beneficial arthropods is a key point in Integrated Pest Management (IPM). Here we present the results of four experiments conducted in vineyards where the effects of chlorpyrifos, thiamethoxam, indoxacarb, flufenoxuron, and tebufenozide were evaluated on the generalist predatory mites Typhlodromus pyri Scheuten and Amblyseius andersoni (Chan...

abstract treating soil with insecticides is thought to be an effective method for termite control. speed of action and repellency of insecticides are important factors for discussing their barrier effects as soil-treatment termiticide. microcerotermes diversus (silvestri) is the most economically destructive termite in structures in ahwaz region, because the species feed on anything with cellul...

Toxicity of three modern insecticides (chlorantraniliprole, thiamethoxam and spinetoram) was examined against the first instar larvae of Pectinophora gossypiella (Saunders). The field rate and other two concentrations were used. The results showed that thiamethoxam was the most effective insecticide followed by chlorantraniliprole and spinetoram. The LC50,s were 8.9, 13.9 and 19 ppm for thiamet...

The pea leaf weevil, Sitona lineatus L. (Coleoptera: Curculionidae), has recently emerged as an important pest of field peas in the Canadian prairies. Systemic seed-coated insecticides may provide a tool for the integrated pest management of this pest. Therefore, several controlled assays were performed in order to determine effects of a recently registered neonicotinoid, (thiamethoxam) on S. l...

There is growing concern over the risk to bee populations from neonicotinoid insecticides and the long-term consequences of reduced numbers of insect pollinators to essential ecosystem services and food security. Our knowledge of the risk of neonicotinoids to bees is based on studies of imidacloprid and thiamethoxam and these findings are extrapolated to clothianidin based on its higher potency...

The objective of the work was to investigate the possibility of using a tricresyl phosphate-based carbon paste electrode for the direct voltammetric determination of the neonicotinoid insecticide thiamethoxam. The analyte was determined by differential pulse voltammetry in Britton–Robinson buffer pH 7.0 in the concentration range of 3.72–41.5 μg mL-1. The reproducibility of the analytical signa...

Neonicotinoid residues in nectar and pollen from crop plants have been implicated as one of the potential factors causing the declines of honey bee populations. Median residues of thiamethoxam in pollen collected from honey bees after foraging on flowering seed treated maize were found to be between 1 and 7 µg/kg, median residues of the metabolite CGA322704 (clothianidin) in the pollen were bet...

The soybean aphid, Aphis glycines Matsumura (Homoptera: Aphididae), is a recent introduction (2000) from Asia and has become a serious soybean [Glycine max (L.) Merr. (Fabaceae)] pest in North America. Seed treatments using the neonicotinoid insecticides, imidacloprid and thiamethoxam, have been suggested as a method of control, and the use of these insecticides is becoming widespread. As a con...
