Observations on the effect of the aerial spraying of abate, used in the control of simulium larvae, on the drift rates of microcrustacea and chaoboridae in the river Oti, Ghana
The Cladocera, Copepoda and the Chaoboridae in River Oti in the Volta Basin area all showed circadian rhythmic behaviour; increasing in number in the drift, between sunset and sunrise. Each group showed more than one peak of drift during the night. The aerial spraying of Abate affected the Cladocera, Copepoda and the Chaoboridae at the dosing site upstream of the Simulium breeding sites, and caused catastrophic drifting of the organisms withone o…
Changes in zooplankton populations in the White Volta with particular reference to the effect of Abate
The 24‐hour LC 50 of the nauplii of Thermocyclops hyalinus using Abate CE 200 solution was 0.23 ppm., while the 24‐hour LC 50 of both the copepodite and adult stages was 0.2 ppm. The numbers of drifting zooplanktonic Microcrustacea in the White Volta increased in numbers during the months of March, April, May, June and July in the dry season. The increase in numbers in the post‐sunset samples related to the vertical migration of the zoqplankton i…
Effect of an organophosphorus insecticide, abate, used in the control of Simulium damnosum on non‐target benthic fauna
The effect of Abate used in the control of Simulium damnosum on non‐target benthic invertebrate organisms was studied in river Oti (West Africa) in the Onchocerciasis Control Programme area. Abate was administered by aerial spraying and pre‐dosing and post‐dosing Surber samples were compared. Baetidae and Leptophlebiidae, two of the three predominating organisms were seriously affected by the Abate. Other non‐target organisms that were killed wer…
