Popis:	WE are assessing the toxicities of new insecticidal compounds as part of a World Health Organization programme to evaluate possible substitutes for the chlorinated hydrocarbons to which anopheline mosquitoes in many countries have become resistant. The experimental trap-hut of the Muirhead-Thomson type1 is used for this assessment as it is a research tool of proved value. There are, nevertheless, a number of weaknesses in its design that lead to errors in assessing insecticide-toxicity: (1) Nearly all resting is on the roof so that the toxicity of the roof-substrate has an over-riding effect on overall mortality. (2) In the presence of a fumigant insecticide an unassessed proportion of mosquitoes die simply due to confinement in the atmosphere of the insecticide in the windowtrap, whereas under natural conditions they would have escaped from the hut and survived. (3) An unassessed proportion of hut-entering mosquitoes leave through the eaves.
