Anopheles albimanus is a Potential Alphavirus Vector in the Americas. [PDF]

Am J Trop Med Hyg, 2023
AbstractDespite its ecological flexibility and geographical co-occurrence with human pathogens, little is known about the ability for Anopheles albimanus to transmit arboviruses. To address this gap, we challenged An. albimanus females with four alphaviruses and one flavivirus and monitored progression of infections.

Heat Shock Causes Lower Plasmodium Infection Rates in Anopheles albimanus. [PDF]

Front Immunol, 2021
The immune response of Anopheles mosquitoes to Plasmodium invasion has been extensively studied and shown to be mediated mainly by the nitric oxide synthase (NOS), dual oxidase (DUOX), phenoloxidase (PO), and antimicrobial peptides activity. Here, we studied the correlation between a heat shock insult, transcription of immune response genes, and ...

Antimicrobial properties of Anopheles albimanus pericardial cells [PDF]

Cell and Tissue Research, 2012
Insect pericardial cells (PCs) are strategically located along the dorsal vessel where they encounter a high hemolymph flow enabling them to undertake their osmoregulatory, detoxifying, and scavenging functions. In this location, PCs also encounter foreign molecules and microorganisms. The response of PCs of the mosquito Anopheles albimanus, one of the

IgG antibody response against Anopheles salivary gland proteins in asymptomatic Plasmodium infections in Narino, Colombia

Malaria Journal, 2020
Background The humoral immune response against Anopheles salivary glands proteins in the vertebrate host can reflect the intensity of exposure to Anopheles bites and the risk of Plasmodium infection. In Colombia, the identification of exposure biomarkers

A Follow-Up to the Geographical Distribution of Anopheles Species in Malaria-Endemic and Non-Endemic Areas of Honduras

Insects, 2022
Anopheles species are the vectors of malaria, one of the diseases with the greatest impact on the health of the inhabitants of the tropics. Due to their epidemiological relevance and biological complexity, monitoring of anopheline populations in current ...

Sublethal exposure to spinetoram impacts life history traits and dengue virus replication in Aedes aegypti

Insect Science, Volume 30, Issue 2, Page 486-500, April 2023., 2023
Graphical Abstract Sublethal spinetoram exposure originates Aedes aegypti females with smaller size and weaker blood‐feeding capacity; sublethal spinetoram exposure prolonged the immature development period in Ae. aegypti; and sublethal spinetoram exposure dysregulates mitochondrial function and stimulates dengue virus replication both in cells and in ...

Repellency Potential, Chemical Constituents of Ocimum Plant Essential Oils, and Their Headspace Volatiles against Anopheles gambiae s. s., Malaria Vector

Journal of Chemistry, Volume 2023, Issue 1, 2023., 2023
African malaria mosquitoes (Anopheles gambiae sensu stricto) transmit a malaria parasite (Plasmodium falciparum) to humans. The current control strategies for the vector have mainly focussed on synthetic products, which negatively impact the environment and human health.

Peptide mediated, enhanced toxicity of a bacterial pesticidal protein against southern green stink bug

Microbial Biotechnology, Volume 15, Issue 7, Page 2071-2082, July 2022., 2022
The damage caused by stink bugs that feed on agricultural crops is significant. Here we describe modification of the pesticidal protein Mpp83Aa1 by addition of peptides that bind to the gut surface proteins alpha amylase or aminopeptidase N. These peptides provided artificial anchors resulting in increased gut binding, and enhanced toxicity against the

Cemeteries as sources of Aedes aegypti and other mosquito species in southeastern Puerto Rico

Tropical Medicine &International Health, Volume 27, Issue 3, Page 300-309, March 2022., 2022
Abstract Objective To investigate the presence and abundance of mosquito species in containers found in different types of cemeteries in Puerto Rico to assess their importance and make control recommendations. Methods We conducted surveys of containers with water in 16 cemeteries in southeastern Puerto Rico to detect the presence of larvae and pupae of
