Abstract Fenitrothion is an organophosphorus insecticide usually found in aquatic ecosystems at concentrations the range of low ng/L. In this manuscript we show that 24 h exposure to environmental fenitrothion, from ng/L ?g/L, altered basal locomotor activity, visual-motor response and acoustic/vibrational escape zebrafish larvae. Furthermore, fenitrothion expression gap43a, gfap, atp2b1a, mbp ...

Insecticidal properties of fenitrothion microcapsules (MC3) as a new residual spraying formulation for mosquito control were studied. Adult female Anopheles albimanus were confined so as to contact several surfaces treated with fenitrothion MC or wettable powder (WP) for 10 and 30 min. Residual efficacy of MC at the rate of 1 g/m2 was almost equivalent to that of WP at the rate of 2 g/m2 on a p...

The process of pesticide (γ-HCH and inactive isomers αand β-HCH, DDT, DMDT, fenitrothion and chlorfenvinphos) removal from industrial wastewater using Fenton's reaction has been analysed. Most of the pesticides were completely degraded at H2O2 concentration of 2.5 g/dm; however, only at 5 g/dm were all the examined pesticides completely removed and the results repeatable. The most effective pro...

Abstract. Fouad MR, El-Aswad AF, Aly MI. 2022. Acute toxicity, biochemical and histological of fenitrothion thiobencarb on fish Nile tilapia (Oreochromis niloticus). Nusantara Bioscience 14: 217-226. The results show that the tested are highly toxic to fish. However, is more (1.6 times) Oreochromis niloticus (Linnaeus, 1758) than thiobencarb. determined 96-h LC50 values using a static bioassay ...

Physicochemical and insecticidal properties of fenitrothion microcapsule (MC) as a new residual spraying formulation for mosquito control were studied. The wall staining after treatment with MC at the rate of 1-2 g AI/m2 was not noticeable as compared with that of wettable powder (WP). Covering rate with MC on a vertical wall was almost the same as WP and emulsifiable concentrate (EC) when the ...

chemical control against overwintered adults of sunn pest eurygaster integriceps put. mostly has low efficacy. today using insecticides and formulations that have durable toxicity on overwintered adults is more approved, because this strategy can reduce treated area against new generation. this research was conducted with six treatments and four replications in randomized complete block design ...

This research aimed to assess the toxicity of the pesticides abamectin 18 CE (0.02 g a.i. L-1), carbaryl 480 SC (1.73 g a.i. L-1), sulfur 800 GrDA (4.8 g a.i. L-1), fenitrothion 500 CE (0.75 g a.i. L-1), methidathion 400 CE (0.4 g a.i. L-1), and trichlorfon 500 SC (1.5 g a.i. L-1) as applied in integrated apple production in Brazil on the survival, oviposition capacity, and egg viability of the...

The behavioral responses ofthree colonized strains of Culex quinquefasciatus, two from recent field collections in Thailand (Nonthaburi and Mae Sot) and one from a long-established colony from the National Institute of Health (NIH), Ministry of Public Health, Thailand, were compared during and after exposure to deltamethrin (0.02 g/m2), propoxur (0.2 g/m2), and fenitrothion (0.2 g/m2) using an ...

OBJECTIVE Fenitrothion residue is found primarily in soil, water and food products and can lead to a variety of toxic effects on the immune, hepatobiliary and hematological systems. However, the effects of fenitrothion on the male reproductive system remain unclear. This study aimed to evaluate the effects of fenitrothion on the sperm and testes of male Sprague-Dawley rats. METHODS A 20 mg/kg...

BACKGROUND Five formulated insecticides (lambda-cyhalothrin at 10 mg m⁻², bifenthrin at 50 mg m⁻², fipronil at 10 mg m⁻², fenitrothion at 50 mg m⁻², imidacloprid at 5 mg m⁻²) and one active ingredient (DDT at 500 mg m⁻²) were evaluated using a surface contact method against early and late instars and adults of two strains of the tropical bed bug, Cimex hemipterus (F.). Synergism of lambda-cyhal...
