Dynamics of Permethrin Resistance in a Colony of Horn Flies (Diptera: Muscidae)

Journal of Medical Entomology, 1991
A colony of horn fly, Haematobia irritans (L.), was established from field-collected, resistant flies. Changes in resistance levels were monitored under a regimen with and without insecticide pressure. The colony remained closed with no introduction of susceptible flies. In the absence of permethrin pressure, resistance levels dropped to 2.5 times from

The structure and function of the respiratory horns of the eggs of some flies

Philosophical Transactions of the Royal Society of London. Series B, Biological Sciences, 1960
Abstract Eggs of flies of the families Sepsidae, Drosophilidae, Sphaeroceridae, Muscidae, and Cordiluridae may have one or more tubular or flattened projections from the anterior part of the shell. These projections are called respiratory horns. The eggs are laid in decomposing vegetable or animal matter. The respiratory horns project
