Evaluating the potential of Kalanchoe pinnata, Piper amalago amalago, and other botanicals as economical insecticidal synergists against Anopheles gambiae.

Background: Synergists reduce insecticide metabolism in mosquitoes by competing with insecticides for the active sites of metabolic enzymes, such as cytochrome P450s (CYPs). This increases the availability of the insecticide at its specific target site. The combination of both insecticides and synergists increases the toxicity of the mixture.

Sequencing confirms Anopheles stephensi distribution across southern Yemen.

The invasion of Anopheles stephensi in Africa warrants investigation of neighboring countries. In this study, genetic analysis was applied to determine the status of An. stephensi in southern Yemen.

DETERMINING A DIAGNOSTIC DOSE OF PIRIMIPHOS-METHYL FOR AEDES AEGYPTI USING TREATED BOTTLES1.

There is a pressing need for innovative strategies to control arboviruses transmitted by Aedes aegypti. The modification of indoor residual spraying to target Ae. aegypti is one such strategy.

Locally Acquired (Autochthonous) Mosquito-Transmitted Plasmodium vivax Malaria - Saline County, Arkansas, September 2023.

A case of locally acquired (autochthonous) mosquito-transmitted Plasmodium vivax malaria was diagnosed in Arkansas in September 2023. This represents the 10th autochthonous case identified nationally in 2023, after 20 years without recorded local mosquitoborne malaria transmission in the United States.
