The paper presents morphological and genetic data on the malarial mosquito Anopheles beklemishevi Stegnii et Kabanova, 1976. It also provides morphological accounts of eggs, age stage IV larvae, and, firstly, pupae and imagoes. The paper considers it possible to use cytogenetic and molecular markers to identify An. beklemishevi.

Malaria remains a significant public health challenge, particularly in low- and middle-income countries, despite ongoing efforts to eradicate the disease. Recent advancements, including the rollout of malaria vaccines, such as RTS,S/AS01 and R21/Matrix-M™, offer new avenues for prevention. However, the rise of resistance to anti-malarial medications necessitates innovative strategies.

Background: The current study sought to re-evaluate malaria prevalence, susceptibility to artemisinin-based combination therapy (ACT), transmission patterns and the presence of malaria vectors in the Kikuyu area of the Kenyan Central highlands, a non-traditional/low risk malaria transmission zone where there have been anecdotal reports of emerging malaria infections.
Methods: Sampling of adult mosquitoes was done indoors, while larvae were sampled outdoors in June 2019. The malaria clinical study was an open label non-randomized clinical trial where the efficacy of one ACT drug, was evaluated in two health facilities.

In this study, the crude chemical constituents extracted from Trichoderma harzianum and their toxicity were evaluated against the larvae, pupae, and adults of Anopheles stephensi at 24 and 48 h post-treatment. Additionally, the chemical constituents of the crude extracts were identified using gas chromatography-mass spectrometry (GC-MS) analysis, and their ability to bind with target proteins was confirmed through molecular docking studies. The results clearly demonstrated that the chemical compounds from T.

parasites can lie dormant in the liver as hypnozoites, activating weeks to months after sporozoite inoculation to cause relapsing malarial illness. It is not known what biological processes govern hypnozoite activation. We use longitudinal data from the most detailed cohort study ever conducted in an area where both and were endemic to fit a simple within-host mathematical model of hypnozoite activation.
