AI Article Synopsis

  • The study investigated the role of different mosquito species as malaria vectors in three rural villages in the Lacandon rainforest of Chiapas, Mexico, during mid-1988.
  • Anopheles vestitipennis was the most common species found, with An. albimanus, An. punctimacula, and An. darlingi also present, each exhibiting distinct feeding habits and preferences for biting humans.
  • The researchers identified An. vestitipennis as a probable vector for Plasmodium vivax, marking the first time this species has been linked to malaria transmission in Mexico, with an infection rate of 4.67 per 1000 mosquitoes tested.

Article Abstract

Baseline studies to evaluate the role of different anopheline mosquitoes as probable vectors of malaria in the Lacandon rainforest region in Chiapas (México) were carried out in 3 rural villages between June and November 1988. Anopheles vestitipennis was the most abundant species in all the villages, followed by An. albimanus, An. punctimacula and An. darlingi. Human bait collections showed that An. vestitipennis and An. albimanus tended to bite man either indoors or outdoors, while An. punctimacula preferred to bite outdoors. Monthly man-biting rates of An. vestitipennis tended to follow the rainfall pattern. Plasmodium vivax was detected in An. vestitipennis only, with an estimated overall infection rate of 4.67 per 1000 mosquitoes (range 0-54.42, of 3500 mosquitoes assayed). This is the first incrimination of An. vestitipennis as a probable vector of P. vivax in México.

Article Synopsis
  • Mexico has significantly reduced malaria cases over the last 20 years and is considering certifying malaria-free areas (MFAs) as a step towards total elimination, with Quintana Roo being a potential candidate.
  • Monitoring the susceptibility of key malaria vectors like Anopheles albimanus is essential for this MFA certification, leading to a study conducted in three localities in Quintana Roo during the rainy season of 2022.
  • The study found that An. albimanus showed high mortality rates against various insecticides, and genetic analysis revealed no mutations in key resistance genes, indicating that the vector population remains susceptible.

Background: Anopheles mosquitoes are the vectors of malaria, one of the most important infectious diseases in the tropics. More than 500 Anopheles species have been described worldwide, and more than 30 are considered a public health problem. In Honduras, information on the distribution of Anopheles spp.

Background: Malaria remains an important public health problem in Latin America, and the development of insecticide resistance in malaria vectors poses a major threat to malaria elimination efforts. Monitoring of insecticide susceptibility and the determination of the mechanisms involved in insecticide resistance are needed to effectively guide the deployment of appropriate vector control measures. Here, molecular assays have been developed to screen for mutations associated with insecticide resistance on the voltage-gated sodium channel (VGSC) and acetylcholinesterase-1 (Ace-1) genes in four malaria vectors from Latin America.

In Mexico, genus Anopheles includes 27 species divided into three subgenera: Anopheles, Kerteszia, and Nyssorhynchus. Some species occur in the Nearctic region (northern Mexico), whereas other species occur in the Neotropical region (south and southeast Mexico) and only a few species occur in both regions. In Quintana Roo State (southeast Mexico) 11 species have been recorded: An.

Background: Campaigns for the continued reduction and eventual elimination of malaria may benefit from new and innovative vector control tools. One novel approach being considered uses a push-pull strategy, whereby spatial repellents are used in combination with outdoor baited traps. The desired effect is the behavioural manipulation of mosquito populations to elicit movement of vectors away from people and into traps.
