Microinjection‐enabled gene silencing in first instar larvae of western flower thrips, Frankliniella occidentalis, reveals vital genes for larval survival

Insect Science, Volume 32, Issue 6, Page 1969-1981, December 2025.
This study introduces a microinjection technique to deliver dsRNA into the hemolymph of first instar larval thrips (L1s) via the foreleg coxa, enhancing survival rates by minimizing internal tissue damage. Significant knockdown of V‐ATPase‐B, CYP3653A2, and ApoLp‐II/I was achieved, with silencing of CYP3653A2 or ApoLp‐II/I increasing larval mortality ...

Nombre probable de Trypanosoma (Nannomonas) congolense transmis par Glossina morsitans Togo

Revue d’Elevage et de Médecine Vétérinaire des Pays Tropicaux, 1984
A la suite d'infection de Glossina morsitans morsitans avec Trypanosoma (N.) congolense "stock" Avetonou et "clone" ILRAD 1323, il a été remarqué qu'une G. morsitans peut émettre, par salivation sur lame chaude, 1 à 251 trypanosomes métacycliques.

Zebra stripes: the questions raised by the answers

Biological Reviews, Volume 100, Issue 6, Page 2660-2680, December 2025.
ABSTRACT Multiple hypotheses have been suggested to explain why the three zebra species (Equus quagga, E. grevyi and E. zebra) are striped. We review how well these theories explain the nature (rather than simply the existence) of the stripes. Specifically, we explore how well different theories explain (i) the form of zebra stripes (especially on ...

Notes sur un élevage de Glossines (Diptera-muscidae) entrepris à partir de pupes expédiées d'Afrique, à Maisons-Alfort

Revue d’Elevage et de Médecine Vétérinaire des Pays Tropicaux, 1966
Les auteurs exposent les techniques employées au laboratoire d'entomologie de l'I.E.M.V., à Maisons-Alfort, pour élever trois souches de glossines: Gl. morsitans morsitans West., en provenance du Tanganyika; Gl.

Tsetse Fly Detection and Sex Classification Model Enrichment Employing YOLOv8 and YOLO11 Architecture

Applied AI Letters, Volume 6, Issue 3, October 2025.
This study developed an automated Tsetse fly sex identification and classification system using CNN‐driven mobile imaging and compared the performance of YOLOv8 and YOLO11 through a performance matrix and statistical analysis involving paired t‐tests and McNemar's test.

Evaluation of two candidate molecules—TCTP and cecropin—on the establishment of Trypanosoma brucei gambiense into the gut of Glossina palpalis gambiensis

Insect Science, Volume 32, Issue 5, Page 1747-1760, October 2025.
This study investigates the potential of enhancing the resistance of Glossina palpalis gambiensis to Trypanosoma brucei gambiense to mitigate the transmission of Human African Trypanosomiasis. We successfully cloned genes encoding proteins of interest in Sodalis strains, resulting in recombinant Sodalis (recSodalis) that were micro‐injected into the L3

Is aging raw cattle urine efficient for sampling Anopheles arabiensis Patton? [PDF]

, 2010
Background: To ensure sustainable routine surveillance of mosquito vectors, simple, effective and ethically acceptable tools are required. As a part of that, we evaluated the efficiency of resting boxes baited with fresh and aging cattle urine for indoor

A proteomics approach reveals molecular manipulators of distinct cellular processes in the salivary glands of Glossina m. morsitans in response to Trypanosoma b. brucei infections

Parasites & Vectors, 2016
BackgroundGlossina m. morsitans is the primary vector of the Trypanosoma brucei group, one of the causative agents of African trypanosomoses. The parasites undergo metacyclogenesis, i.e.

Potential of entomopathogenic fungi for Glossina austeni control: insights into microbiome alterations and implications on sustainable management of the pest

Insect Science, Volume 32, Issue 5, Page 1691-1712, October 2025.
Abstract Glossina austeni Newstead (Diptera: Glossinidae) is a competent vector of the trypanosomes causing human African trypanosomiasis and the African animal trypanosomosis. Management of this pest has primarily involved trapping methods, Sterile Insect Technique, and research into vector competence–symbiotic interactions.

Repellent Properties of δ-Octalactone Against the Tsetse Fly,Glossina morsitans Morsitans [PDF]

Journal of Insect Science, 2008
Delta-octalactone, produced by several Bovidae, has been suggested as a potential repellant of tsetse fly attack. Racemic delta-octalactone was synthesized via an abbreviated route. The product was assayed against 3-day old starved teneral female tsetse flies, Glossina morsitans morsitans Wiedemann (Diptera: Glossinidae), in a choice wind tunnel and ...
