“…Kano et al (1972) reported that the presence of long hairs on the second segment of the hind tarsi of male is a differentiating character between H. exigua and H. irritans. Parashar et al (2001) and Low et al (2017) have also reported that H. exigua is prevalent in India and Southeast Asia. Out of 239 ies examined, 101 and 138 ies were male and female respectively.…”

The efficacy of flumethrin 1% pour-on (1% w/v, Flumitas) was evaluated against Haematobia exigua on cattle farms in Namakkal district, Tamil Nadu from November 2019 to February 2020. In this study, five farms, which had fly menace, selected randomly were divided as treatment (F1, F2, F3 and F4) and control (Fc) groups. Flies collected from the farms were identified as Haematobia exigua and a mean pre-treatment intensity was 195.56 ± 14.07. In the treatment groups (F1,F2,F3 and F4) flumethrin 1% pour on was applied to the back of cattle at the rate of 1 ml/10 kg body weight and fly intensity was recorded for a period of 2 months. The fly intensity reduced to zero within 30 minutes of application and the same trend continued till 28 DPT in F2 and F3, while it was effective 35 DPT in F1 and F4. A highly significant difference in the mean H. exigua fly counts between control and treatment group (P < 0.0001) was observed.

Static bioassays were made in the laboratory to determine lethal concentration of the pyrethroid pesticide fenvalerate [(RS)-alpha-cyano-3-phenoxybenzyl (RS)-2-(4-chlorophenyl)-3-methylbutyrate] for the freshwater catfish Clarias gariepinus and effects of sublethal concentrations of the pesticide on some biochemical parameters of the fish. For exposure periods of 24 to 96 h, LC(50) values of fenvalerate ranged from 5.83-4.76 micro g/L and 4.24-2.94 micro g/L, respectively for water and acetone soluble fenvalerate. Two sublethal concentrations of fenvalerate were used in the bioassays for biochemical parameters: 2.1 micro g/L for 24 h and 1.4 micro g/L for 96 h exposure, both concentrations representing 50% of LC(50) value of acetone soluble fenvalerate for the respective exposure period. Hepatosomatic index, liver glycogen, alkaline phosphatase of liver and ascorbic acid of blood, liver, and kidney decreased while haemoglobin (Hb) %, plasma glucose levels and acid phosphatase level of liver increased after 24 h exposure to 2.1 micro g/L fenvalerate. Longer exposure (96 h) to even a lower concentration (1.4 micro g/L) of fenvalerate resulted in reduction of all the parameters (except Hb %) tested as compared with control. Fish previously fed for 60 days with a diet supplemented by a high level of ascorbic acid (100 mg/100 g diet) could reverse most of the effects caused by 24 h exposure to 2.1 micro g/L fenvalerate. A lower level of ascorbic acid (50 mg/ 100 g diet) supplement could not influence these effects of fenvalerate. Even the higher dose of ascorbic acid supplementation (100 mg/100 g diet) could not relieve the stress parameters, except for Hb% and HSI, when the pesticide was applied at 1.4 micro g/L for a longer time period (96 h).
