AbstractTargets of black cloth with or without flanking netting panels (ca. 1 m tall × 1.7 m) baited with acetone (130 mg/h) and 1-octen-3-ol (0.5 mg/h), coated with deltamethrin suspension concentrate and deployed at 4/km2, produced a decline of 3% per day in the apparent density of the tsetse fly Glossina morsitans centralis Machado in 500 km2 of the Western Province of Zambia. Flies were eradicated in a year as evidenced by the absence of catches from flyrounds and traps and the elimination of the transmission of trypanosomiasis. The promise of the target technique is confirmed but the need for its further development is emphasized.

Rabbits exposed to feeding tsetse flies developed cutaneous hypersensitivity responses to fly bites. These responses had characteristics of immediate and delayed type hypersensitivity. Saliva components from the tsetse fly Glossina morsitans centralis were electrophoretically separated by sodium dodecyl sulfate-poly-acrylamide gel electrophoresis. Major salivary proteins of 160, 92, 66, 64, 55, 42, 33, 28, and 15 kilodaltons were identified. Separated salivary components were transferred to nitrocellulose filters and probed with lectins and with whole sera and purified IgG from rabbits which had been exposed, via fly feeding, to tsetse antigens for variable periods. Many of the salivary proteins were identified as glycoproteins. Several major salivary proteins were recognized by antibodies from sensitized rabbits.
