The present study was carried out at the research field of Department Entomology, Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur, Bangladesh, during tomato (Solanum lycopersicum L.) growing seasons 2021 and 2022 to evaluate pest management benefit 4 insecticides, viz. Karate 2.5 ec (λ-cyhalothrin), Ripcord 10 (cypermethrin), Marshal 20 (carbosulfan), Shobicron 425 (profenofo...

Publication history: Received on 26 October 2022; revised 13 December accepted 15 2022 Abstract: Introduction: Alpha-cypermethrin (Pyrethroid insecticide) is widely used in disease vector control, agriculture, home pest control and protection of foodstuff across the world. Due to its unchecked widespread use, non-target organisms are also getting affected by toxic effects. Objectives: This inve...

Purpose: Cypermethrin (class II) belongs to pyrethroid insecticides which have been in wide use control various pests including moth of cotton, fruit and vegetable crops. This study was aimed investigate the effects cypermethrin on haematology female rats their modulation by co-administration sodium selenite. Methodology: Four equal groups were made (n=20). Group 1 received ml corn oil, 2 admin...

b a ckground: the long-lasing insecticide impregnated nets (llins) is considered as an effective tools for malaria vector control. the aim of this study was to evaluate the residual efficacy of alpha-cypermethrin long lasting im- pregnated nets (llin-interceptor®) against anopheles stephensi using tunnel test. m e t hods: the wash-resistance of interceptor® nets were assessed under laboratory c...

Triatoma infestans is the most important vector of Chagas' disease in Argentina. Experiences from Argentine national campaigns have shown indoor spraying to control triatomine bugs is both expensive and difficult. An alternative control method may be the use of pyrethroid-impregnated fabrics (PIFs), which could be both a practical and cheap complement to conventional control measures. In this s...

Aquatic life water quality criteria were derived for five pyrethroids using a new methodology developed by the University of California, Davis (TenBrook et al.2010). This methodology was developed to provide an updated, flexible, and robust water quality criteria derivation methodology specifically for pesticides. To derive the acute criteria, log-logistic SSDs were fitted to the medium-sized b...

Pyrethroids, commercially available pesticides, are greatly in use these days, and thus they carry considerable chances of contaminating various ecosystems. Haematotoxicity of cypermethrin, a broadly used type II pyrethroid, has been assessed in the present study. Selected parameters included determination of total RBC count, haemoglobin concentration (Hb conc.), packed cell volume (PCV), mean ...

The present study is a summary of the current level of the insecticide resistance to selected organophosphates, pyrethroids, and neonicotinoids in seven Indian field populations of Bemisia tabaci genetic groups Asia-I, Asia-II-1, and Asia-II-7. Susceptibility of these populations was varied with Asia-II-7 being the most susceptible, while Asia-I and Asia-II-1 populations were showing significan...

Previously, laboratory experiments have revealed that freely diluted azole fungicides potentiate the direct toxic effect of pyrethroid insecticides on Daphnia magna. More ecologically relevant exposure scenarios where pesticides are adsorbed have not been addressed. In this study we exposed beech leaves (Fagus sylvatica) to the azole fungicide propiconazole (50 or 500 μg L(-1)), the pyrethroid ...

Pyrethroids are now the world's most extensively used insecticides. One of the common metabolic routes of pyrethroid insecticides in living systems is hydrolysis by carboxylesterases, and this hydrolysis may be stereospecific since most pyrethroid insecticides have chiral centers. In previous studies, pyrethroid-like fluorescent substrates have been shown to be hydrolyzed in a fashion similar t...
