Glossina pallidipes

Glossina palpalis and G. morsitans from a 1920 lexicon Tsetse have an unusual lifecycle which may be due to the richness of their food source. A female fertilizes only one egg at a time and retains each egg within her uterus to have the offspring develop internally during the first three larval stages, a method called adenotrophic viviparity Tsetse flies (Glossina spp.) are the prominent vector of African trypanosome parasites (Trypanosoma spp.) in sub-Saharan Africa, and Glossina pallidipes is the most widely distributed species in Kenya. This species displays strong resistance to infection by parasites, which are typically eliminated in the midgut shortly after acquisition from the mammalian host The Glossina pallidipes salivary gland hypertrophy virus (GpSGHV) infects tsetse flies predominantly asymptomatically and occasionally symptomatically. Symptomatic infections are characterized by overt salivary gland hypertrophy (SGH) in mass reared tsetse flies, which causes reproductive dysfunctions and colony collapse, thus hindering tsetse control via sterile insect technique (SIT) Glossina pallidipes Taxonomic Tree; Domain: Eukaryota Kingdom: Metazoa Phylum: Arthropoda Subphylum: Uniramia Class: Insecta; Host Animals; Bos indicus (zebu) Bos taurus (cattle) Bubalus bubalis (Asian water buffalo) Capra hircus (goats) Diceros bicorni

The genus Glossina is usually divided into three species groups. The fusca group includes several vectors of livestock trypanosomiasis. The palpalis group (mainly G. palpalis, G. tachinoides, and G. fuscipes) mainly transmits T. gambiense in west and central Africa The tsetse fly Glossina pallidipes , the major vector of the parasite that causes animal African trypanosomiasis in Kenya, has been subject to intense control measures with only limited success. The G. pallidipes population dynamics and dispersal patterns that underlie limited success i The tsetse fly that carries human tryps is the rarer species (Glossina pallidipes) and a thicket dweller, and usually more common in the Lowveld areas ofZimbabwe We evaluated the effect of crude zebra skin odors on catches of wild savannah tsetse flies (Glossina pallidipes Austen, 1903) using unbaited Ngu traps compared to the traps baited with two known tsetse fly management chemicals; a repellent blend derived from waterbuck odor, WRC (comprising geranylacetone, guaiacol, pentanoic acid and δ-octalactone), and an attractant comprising cow urine and acetone, in a series of Latin square-designed experiments. Coupled gas chromatography. Glossina pallidipes is a vector of African trypanosomiasis. Here we characterize eight new polymorphic microsatellite loci in 288 G. pallidipes sampled from 12 Kenya populations. The number of alleles per locus ranged from four to 36 with a mean of 20.5 ± 10.1

Glossina pallidipes is one of the tsetse species which transmits African Trypanosomiasis. In Tanzania, G. pal-lidipes is widely distributed, hence of economic import-ance in the epidemiology of African Trypanosomiasis. The disease is a stumbling block for diversification of agricultural activities as well as socio economic well be-ing of rural. The Glossina hytrosavirus (family Hytrosaviridae) is a double-stranded DNA virus with rod-shaped, enveloped virions. Its 190 kbp genome encodes 160 putative open reading frames. The virus replicates in the nucleus, and acquires a fragile envelope in the cell cytoplasm. Glossina hytrosavirus was first isolated from hypertrophied salivary glands of the tsetse fly, Glossina pallidipes Austen.

These results showed that the ratio of the number of flies intercepted on the outside of the electric nets to the number on the inside was lower than predicted by this. The polymerase chain reaction (PCR) was used to identify trypanosomes in Glossina pallidipes and G. longipennis caught in Kenya. Of 3826 flies dissected, 188 (4.9%) were parasitologically positive overall.

Sexual responses of adult male G. pallidipes towards baited decoys show that a contact sex pheromone for this species is present in the hydrocarbon fraction of the adult female cuticle. Results are consistent with the view that the pheromone is a C35 compound and is present in sufficient quantity in newly emerged females to elicit maximum. Several species of tsetse flies can be infected by the Glossina pallidipes salivary gland hypertrophy virus (GpSGHV). Infection causes salivary gland hypertrophy and also significantly reduces the fecundity of the infected flies. To better understand the molecular basis underlying the pathogenesis of this unusual virus, we sequenced and analyzed its genome. The GpSGHV genome is a double.

Tests of these ideas focus on long-lived vertebrates: few measure age-related reproductive output in iteroparous invertebrates, or partition reserves. II. Tsetse Flies-Glossina Species 1. PARASITES BACTERIA Bacterium mathisi G. morsitans (flies die after emerging, infected orally) (Roubaud&Treillard, 1935, 1936). Various other bacteria have been recorded but none are knownto bepathogenic. FUNGI PHYCOMYCETES G. morsitans A. (thought to be pathogenic; 20%offlies infected in Tanganyika (Nash, 1933). Cicadomyces sp The first step was to determine the range of attraction of such traps for the main trypanosome vector in Kenya, Glossina pallidipes, although some data were also obtained for G. brevipalpis. Two different techniques were used. Firstly traps were placed at varying distances apart, resulting in competition and consequent reduction of catch sizes. Background: Glossina pallidipes is a haematophagous insect that serves as a cyclic transmitter of trypanosomes causing African Trypanosomiasis (AT). To fully assess the role of G. pallidipes in the epidemiology of AT, especially the human form of the disease (HAT), it is essential to know the microbial diversity inhabiting the gut of natural fly populations Résultats pour : Glossina pallidipes Format d'export ASCII Citation Atom Dublin Core EndNote EndNote-Indicateurs (agents Cirad) HTML Citation Object IDs Zotero - Reference Manager (RIS) RSS 1.0 RSS 2.
