Bacteria in Midguts of Field-Collected Anopheles albimanus Block Plasmodium vivax Sporogonic Development
TLDR
The overall midgut bacterial infection in mosquito field populations may influence P. vivax transmission, and could contribute to explain the annual variations in malaria incidence observed in the area. Expand
Diversity of Bacillus thuringiensis Strains from Latin America with Insecticidal Activity against Different Mosquito Species
TLDR
This strain, harboring cry11, cry30, cyt1, and cyt2 genes, could be relevant for future resistance management interventions and the PCR screening strategy presented here led to identify a putative novel cry11B gene. Expand
Resistance management strategies in malaria vector mosquito control. Baseline data for a large‐scale field trial against Anopheles albimanus in Mexico
TLDR
Biochemical assays showed that the DDT resistance was caused by elevated levels of glutathione S‐transferase (GST) activity leading to increased rates of metabolism of DDT to DDE, suggesting that this is the only majorDDT resistance mechanism in this population. Expand
Scorpine, an anti‐malaria and anti‐bacterial agent purified from scorpion venom
A novel peptide, scorpine, was isolated from the venom of the scorpion Pandinus imperator, with anti‐bacterial activity and a potent inhibitory effect on the ookinete (ED50 0.7 μM) and gamete (ED50Expand
Antimalarial 4-phenylcoumarins from the stem bark of Hintonia latiflora.
TLDR
The EtOAc extract of the stem bark of Hintonia latiflora showed the suppression of total parasitemia and the chemosuppression of schizont numbers, when tested in vivo against Plasmodium berghei infection in mice, leading to the isolation of the new compound 5-O-beta-D-glucopyranosyl-7,4'-dimethoxy-3'-hydroxy-4-phenylcoumarin.

Cytochrome P450-based resistance mechanism and pyrethroid resistance in the field Anopheles albimanus resistance management trial
TLDR
Most correlations of cytochrome P-450 levels and PYR resistance were lost during the third year, indicating that another mechanism evolved in resistant mosquito populations. Expand
Oviposition habitat selection for a predator refuge and food source in a mosquito
Abstract.  1. The influence of filamentous algae on oviposition habitat selection by the mosquito Anopheles pseudopunctipennis and the consequences of oviposition decisions on the diet, development,Expand
Nation-Wide, Web-Based, Geographic Information System for the Integrated Surveillance and Control of Dengue Fever in Mexico
TLDR
A web based, geographically enabled, dengue integral surveillance system (Dengue-GIS) was developed for the nation-wide collection, integration, analysis and reporting of geo-referenced epidemiologic, entomologic, and control interventions data. Expand
Resistance management strategies in malaria vector mosquito control. A large‐scale field trial in Southern Mexico
TLDR
Biochemical assays showed that DDT resistance was primarily caused by elevated levels of glutathione S-transferase (GST) activity leading to increased rates of metabolism of DDT to DDE, suggesting that this is the only majorDDT resistance mechanism in this population. Expand
Plasmodium berghei ookinetes induce nitric oxide production in Anopheles pseudopunctipennis midguts cultured in vitro.
TLDR
Observations demonstrate that reactive oxygen and nitrogen intermediates constitute a part of the cytotoxic arsenal employed by Anopheles mosquitoes against microbial pathogens and Plasmodium ookinetes. Expand
