A behavioural bioassay to identify attractive odours for Glossinidae
Medical and Veterinary Entomology, 1987Abstract. 1. A behavioural bioassay, based on antennal movement responses, was developed using Glossina morsitans morsitans Westwood for screening chemical attractancy to tsetse. 2.

Odor-Induced Host Location in Tsetse Flies (Diptera: Glossinidae)
Journal of Medical Entomology, 1994Four aspects of olfaction in host location by tsetse flies, Glossina spp., are discussed as follows: (1) host location and its mechanism, (2) factors affecting host location, (3) kairomones and host location, and (4) kairomones and host selection.

Sampling Problems with Tsetse Flies (Diptera: Glossinidae)
The Journal of Applied Ecology, 1978(1) Studies were made of Glossina morsitans morsitans Westw. and G. pallidipes Aust. captured from (a) stationary sources of ox odour (electric trapping); (b) natural refuges and branch resting places (hand-net catching); (c) artificial refuges (curtain trapping): (d) a mobile ox (hand-net); and (e) mobile screens (electric and hand-net).

The Glossinidae, or tsetse-flies, form a monogeneric family of the Diptera. The adults range in length from 6 to 14 mm and in all the 23 known species are various shades of brown — ranging from light yellowish brown to dark blackish brown. In some species the abdomen has alternate darker and lighter bands. Female flies give birth, at intervals of about

Host preferences of tsetse (Diptera: Glossinidae) based on bloodmeal identifications
Medical and Veterinary Entomology, 1998An enzyme‐linked immunosorbent assay (ELISA) was developed to identify the origin of vertebrate blood in the guts of 29 245 wild‐caught flies of eleven Glossina species from various ecological zones of Africa.

Respiratory pattern transitions in three species of Glossina (Diptera, Glossinidae)
Journal of Insect Physiology, 2011Glossina exhibit cyclic ((CYC)GE) or continuous gas exchange ((CON)GE) patterns at rest. However, the factors influencing the transition from one pattern to another are not well understood for these or other insect species. This study examines which factors could aid in predicting the presence or absence of (CYC)GE in adults of three Glossina species ...

Laboratory analyses of vision in tsetse flies (Dipt., Glossinidae)
Bulletin of Entomological Research, 1973Histological examination of the eyes ofGlossina morsitansWestw. andG. austeniNewst. showed that visual acuity, as calculated from ommatidial size and interommatidial angle, varies in different zones and planes of the eye, being greatest in the forward-facing region.

Distribution of Glossina (Diptera: Glossinidae) in Mali
Bulletin of Entomological Research, 1982AbstractBased on the results of field surveys carried out between May 1977 and June 1981, the distributions of Glossina morsitans submorsitans Newst., G. palpalis gambiensis Vanderplank and G. tachinoides Westw. in Mali are presented and compared with previously reported information. The distributions of both G. m. submorsitans and G. p.

Salivary secretion in three species of tsetse flies ("Glossinidae")
Acta tropica, 1975The study of the mechanism and process of salivation in tsetse flies is of paramount importance towards a fuller understanding of the transmission of trypanosomiasis and nagana diseases. Gordon, Crewe and Willett (1956) made direct observations, through a microscope, of the haustellum of G.

Glossina (Diptera: Glossinidae) population growth rates
Bulletin of Entomological Research, 1981AbstractDifferences in population growth rates, r, and net reproductive rates, R0, are shown between Glossina palpalis gambiensis Vanderplank, G. palpalis palpalis (R.-D.), G. morsitans morsitans Westw., G. morsitans centralis Machado, G. pallidipes Aust. and G. fuscipes fuscipes Newst. from field-collected data and laboratory colonies.
