Successful application of deltamethrin pour on to cattle in a campaign against tsetse flies (Glossina spp.) in the pastoral zone of Samorogouan, Burkina Faso.

1,500-2,000 head of cattle were treated with deltamethrin 1% Spot On in an area of high tsetse densities, notably of Glossina morsitans submorsitans. After four treatments at monthly intervals, the time between two treatments was increased to two months. 11 months after the commencement of the campaign the fly population had decreased from initially 54.

Simultaneous control of ticks and tsetse flies in Satiri, Burkina Faso, by the use of flumethrin pour on for cattle.

Treatments of 2000 cattle at monthly intervals with flumethrin pour on (1 mg active ingredient/kg b.w.) resulted in a rapid decrease of African Animal Trypanosomosis (AAT).

The residual effect of deltamethrin Spot On when tested against Glossina palpalis gambiensis under fly chamber conditions.

Groups of single zebu cattle were exposed to infestations of the tsetse fly Glossina palpalis gambiensis in fly chambers following treatment with a pour on formulation of deltamethrin, Coopers* Spot On. During the experiment one animal was maintained in a stall, the other exposed at intervals to sunlight. Both mortality and knockdown of exposed flies was demonstrated.

Effects of Flumethrin Pour-on against Glossina palpalis gambiensis (Diptera, Glossinidae).

1920 males and females of Glossina palpalis gambiensis were fed 3 times on a Zebu treated with Flumethrin Pour-on. This resulted in a significant increase of the mortality and abortion rate of the flies. The fly-specific effects of Flumethrin Pour-on were time-dependent: Clear effects on the performance of the flies were observed during the first 20 days after treatment of the Zebu; an initial 90% "knock down" effect decreased to 40% during the first 15 days.
