Resting patterns of Anopheles gambiae in experimental huts treated with malathion

Transactions of the Royal Society of Tropical Medicine and Hygiene, 1966
Abstract A study, with special reference to resting habits, was made of the effects of malathion on A. gambiae entering experimental huts of the window-trap type. In untreated experimental huts with grass roofs, or with roofs lined with mud, about 80% of A. gambiae indoors rested on the roof at night and in the daytime.

Biting patterns of Anopheles minimus complex (Diptera: Culicidae) in experimental huts treated with DDT and deltamethrin

Journal of Vector Ecology, 2008
Biting patterns of natural populations of Anopheles minimus s.l. females entering experimental huts treated with DDT and deltamethrin were carried out at Pu Teuy Village, Sai Yok District, Kanchanaburi Province, western Thailand. Two experimental huts, control and treatment, were constructed in the fashion of local Thai homes. Pre-spray biting activity

Experimental validation activities of HUT snow emission model

2009 IEEE International Geoscience and Remote Sensing Symposium, 2009
Modeling of snow emission properties on microwave frequencies is necessary in order to understand the complex relations between the snowpack microwave emission and its characteristics, such as density, snow grain size, moisture content and snowpack vertical structure.

Multiple-Layer Adaptation of HUT Snow Emission Model: Comparison With Experimental Data

IEEE Transactions on Geoscience and Remote Sensing, 2010
Modeling of snow emission at microwave frequencies is necessary in order to understand the complex relations between the emitted brightness temperature and snowpack characteristics such as density, grain size, moisture content, and vertical structure.

A Modified Window-trap for Assessment of Fumigant Insecticides in Experimental Trap-huts

Nature, 1963
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 ...

Experimental Study on Radiometric Performance of Synthetic Aperture Radiometer HUT-2D—Measurements of Natural Targets

IEEE Transactions on Geoscience and Remote Sensing, 2011
This paper describes the analysis of L-band radiometric measurement data gathered with the synthetic aperture radiometer HUT-2D during several ground-based and airborne measurement campaigns. The radiometric data are analyzed from the instrument's performance point of view, aiming to verify the theoretical performance of an instrument of this kind and ...

[An experimental tool essential for the evaluation of insecticides: the testing huts].

Bulletin de la Societe de pathologie exotique (1990), 2003
The following study analyses the potentialities of the experimental huts built in M'be Valley (Côte d'Ivoire) where the evaluations of the insecticide products have been carried out for many years in line with the WHOPES protocol on the methodology of stage 2 assays.
