Do invasive house geckos exacerbate dengue fever epidemics?

We have previously linked house geckos to increased dengue vector abundance in habitats where their main predator is absent. Here we pose a hypothesis that the invasion of house geckos may exacerbate dengue fever epidemics.

Dengue vector food webs: geckos, spiders and mosquitoes

The large tokay gecko was found to feed on smaller house geckos (Hemidactylus spp.), which caused an increase in spiders due to reduced predation. Subsequently this resulted in less Aedes mosquitoes. In forest habitats… more

Invasive house geckos (hemidactylus spp.): their current, potential and future distribution

House gecko are common predators of dengue vectors that can be found in many houses in the tropics. Several species occur in Thai homes of which the most common species are the Asian house gecko (Hemidactylus frenatus) and the flat-tailed house gecko (H. platyurus). Hemidactylus species can be found in many parts of the world. more

Container-breeding mosquitoes and predator community dynamics along an urban-forest gradient: The effects of habitat type and isolation

Various studies have shown that the prevalence of mosquito borne diseases such as malaria and dengue fever is correlated to deforestation and urbanization. Some factors that can explain such a correlation are, for example, changes in micro-climatic conditions that come with such changes in the landscape but also … more

Aquatic predators of mosquito larvae in Kamphaeng Phet Thailand

Aquatic mosquito predators play a vital role in the natural control of mosquito populations. Therefore, we investigated the predation rates, prey preference, and other feeding characteristics of aquatic mosquito predators that occur within our region of activity, Kamphaeng Phet, Thailand. more

Are geckos the new mice?

Previously we reported on the flat-tailed house gecko feeding on rice. Here we report similar behaviour on a much larger species: Gecko monarchus. This species belongs to the same family as the Tokay gecko, which is known to feed on smaller gecko species… more.

Opportunistic feeding in flat-tailed house geckos

House geckos are well adapted to living in urban environments. Opportunism is a strategy that helps species cope with changing environments. In the case of house geckos this may also promote successful invasion of new regions. Read here how flat-tailed house geckos are scavenging from garbage bins.

Prey preference of the Common House Geckos Hemidactylus frenatus and Hemidactylus platyurus

One predator of mosquitoes that is often found inside houses in the tropics are the house geckos. House geckos can be found in all colors and sizes and you can see them often feeding on insects that are attracted to lights. During the day they often hide in dark places, where mosquitoes often hide as … more

Predation on mosquitoes by common Southeast Asian house-dwelling jumping spiders (Salticidae)

Inside homes spiders are common mosquito predators. But how effective are they at controlling mosquitoes? How many mosquitoes can a spider eat per day? These are valid questions if we seriously want to consider spiders as a biological control agent … more

Dietary analysis of five insectivorous bat species from Kamphaeng Phet, Thailand

Bats are voracious insectivores and may potentially play a role in the control of vector mosquitoes. We analyzed the diets of five bat species in central Thailand and found considerable amounts of mosquitoes in the feces of bats from an urban colony … more

Tadpoles of three Thailand anuran species do not prey on mosquito larvae

Tadpoles are often considered to be important predators of mosquito larvae. Hence, we experimentally investigated the predation potential of three different frog species that are common in central Thailand. Unlike generally assumed the tadpoles in our study … more

Predation rates of mixed instar Odonata naiads feeding on Aedes aegypti and Armigeres moultoni (Diptera: Culicidae) larvae

Aquatic predators can have a profound impact on the abundance of mosquito larvae. Such predators can include fish such as guppies but also aquatic insects such as backswimmers (Notonectidae) and dragonfly naiads (larvae) … more
