Effects of Different Combinations of Sterile and Fertile Thaumatotibia leucotreta on Fruit Infestation and Population Growth Rate

open access: yesJournal of Applied Entomology, Volume 150, Issue 2, Page 137-146, March 2026.
ABSTRACT Thaumatotibia leucotreta (Meyrick) (Lepidoptera: Tortricidae) is a key phytosanitary pest of citrus in South Africa. The pest damages fruit by burrowing and feeding on the pulp, thus causing yield losses and export rejections. There are several T. leucotreta management strategies, such as orchard sanitation, mating disruption, attract‐and‐kill,

Environmental heterogeneity drives tsetse fly population dynamics and control

open access: yes, 2018
A spatially and temporally heterogeneous environment may lead to unexpected population dynamics. Knowledge still is needed on which of the local environment properties favour population maintenance at larger scale.

Optimising targets for tsetse control: Taking a fly’s-eye-view to improve the colour of synthetic fabrics

open access: yesPLoS Neglected Tropical Diseases, 2019
The savannah tsetse flies, Glossina morsitans morsitans and G. pallidipes, are important vectors of Rhodesian human African trypanosomiasis and animal African trypanosomiasis in East and southern Africa.

The Effect of Differing Levels of Intrasexual and Intersexual Selection on Survival and Reproduction Under a Heatwave

open access: yesEcology and Evolution, Volume 16, Issue 2, February 2026.
Precopulatory mating behaviour, are important for fitness and can be disrupted by heatwave's. Here we assess how differing levels of intrasexual and intrasexual selection in precopulatory mating behaviours impacts fitness responses to heatwaves. We find that the likelihood of having a brood is impacted by differences in intrasexual and intersexual ...

Bed bug preferences for host odor or aggregation odor are differentially modulated by physiological state in various odorscapes

open access: yesPest Management Science, Volume 82, Issue 2, Page 1426-1436, February 2026.
The bed bug olfactory system is highly tuned to two odor sources with dedicated odor information‐processing pathways that are modulated by the satiety–hunger state. Understanding the dynamic nature of switching odor preferences at different phases of blood digestion will contribute to the development of lures with host kairomones and aggregation ...

A colour opponent model that explains tsetse fly attraction to visual baits and can be used to investigate more efficacious bait materials.

open access: yesPLoS Neglected Tropical Diseases, 2014
Palpalis group tsetse flies are the major vectors of human African trypanosomiasis, and visually-attractive targets and traps are important tools for their control. Considerable efforts are underway to optimise these visual baits, and one factor that has

Benefit-Cost Analysis and Socio-Economic Considerations of Trypanosomiasis Control and Treatment in Northern Ghana [PDF]

open access: yes
The paper estimates the cost of tsetse control and treatment of trypanosomiasis and the benefits involved, using benefit-cost analysis. It also estimates the extent to which socio-economic characteristics of farmers affect the use of tsetse control ...

Molecular variation of Trypanosoma brucei subspecies as revealed by AFLP fingerprinting [PDF]

open access: yes, 2002
Genetic analysis of Trypanosoma spp. depends on the detection of variation between strains. We have used the amplified fragment length polymorphism (AFLP) technique to develop a convenient and reliable method for genetic characterization of Trypanosome ...

Seasonal Dynamics and Associated Risk Factors of Bovine Trypanosomosis and Its Vector in Selected Districts of Gamo and Gofa Zones, Southern Ethiopia

open access: yesVeterinary Medicine and Science, Volume 12, Issue 1, January 2026.
The median PCV of poor body‐conditioned animals is below 20 (anaemic) compared to corresponding body‐condition animals. Black‐ and red‐coloured animals are more significantly affected by trypanosomosis than white‐coloured animals. Multivariable logistic regression revealed more about contributory factors than univariable logistic regression.

Genetic diversity and population structure of the tsetse fly Glossina fuscipes fuscipes (Diptera: Glossinidae) in Northern Uganda: Implications for vector control

open access: yesPLoS Neglected Tropical Diseases, 2017
Uganda is the only country where the chronic and acute forms of human African Trypanosomiasis (HAT) or sleeping sickness both occur and are separated by < 100 km in areas north of Lake Kyoga.
