Introduction to Host Seeking

Anopheline mosquitoes are the sole vectors of malaria and rely on olfactory cues for host seeking in which ammonia derived from human sweat plays an essential role.

The olfactory system of insects is crucial in modulating behaviors such as host seeking, mating, and oviposition.

Here, we describe the neural basis of temperature-driven host seeking in parasitic nematodes using the human threadworm Strongyloides stercoralis.

We conclude that the HDT is an effective sampling device for outdoor host seeking An.

Although most mosquito species exhibit crepuscular activity by primarily host seeking at dawn and dusk, Ae.

The control is based on the use of textiles and household items treated with mosquito repellents which alter the mosquitos' host seeking behaviour.

Local morphological anomalies can impair tick’s off-host survival, host seeking activities and successful completion of a blood meal.

During the parasitic generation, infective third-stage larvae (iL3s) actively engage in host seeking.

Background Studies comparing novel collection methods for host seeking and resting mosquitoes A.

Coincidentally, we also show that indole inhibits the animal-host seeking behavior of female Aedes aegypti.

We conclude with a discussion of specific differentially expressed genes and their potential to influence host seeking behaviors of Cx.

The purpose of this review is to provide an overview of how intrinsic factors, including adult maturation, age, nutritional status, and infection, affect the attraction to plants and feeding on plant fluids, host seeking, blood feeding, supplemental feeding behaviours, pre-oviposition behaviour, and oviposition in female mosquitoes.

Anopheline mosquitoes are the sole vectors of malaria and rely on olfactory cues for host seeking in which ammonia derived from human sweat plays an essential role.

HDT and MET show potential for sampling outdoor host seeking mosquitoes.

Although most mosquito species exhibit crepuscular activity by primarily host seeking at dawn and dusk, Ae.

A well coordinated neuro-olfactory regulation is essential for a successful host seeking and blood feeding behavior of adult female mosquitoes.

The olfactory system of insects is essential in many crucial behaviors, such as host seeking, mate recognition, and locating oviposition sites.

Clade-specific innovations spurring the MMPR included long, flexible ovipositors (wasps), host seeking, triungulin and planidium larvae (mantispids, beetles, twisted-wing parasites, flies), and extrudable, telescoped ovipositors (flies).

These observations support previous findings on the role of human host-associated cues in host seeking and confirm the role of CO2 as a synergist, but not a host-seeking cue on its own.

Here we demonstrate the use of thermal imaging and Mosquito Magnet Independence Traps (MMIT) to assess the abundance, diversity and infection rates in mosquitoes host seeking near long-tailed macaque (Macaca fasicularis) sleeping sites in the Lower Kinabatangan Wildlife Sanctuary, Malaysian Borneo.

The sensilla on the antennae and maxillary palps are the most important olfactory organs, via which the insect can perceive the semiochemicals to adjust their host seeking and oviposition behaviors.

Host seeking is an essential process in mosquito reproduction.

Foraging, host seeking, mating, ovipositing and other forms of chemical communication are based on olfaction, which requires the participation of multiple olfactory genes.

Host seeking behaviour of both sexes is dependent on adult sexual maturation.

Odours mediate host seeking pre-blood meal, while post-blood meal females are refractory to host odours for at least 24 h.

We have previously demonstrated that the onset of host seeking in An.

aegypti had bimodal patterns of host seeking, being highest during early morning and late afternoon hours.

Previously, the functional ablation of a family of Aedes aegypti olfactory receptors, the odorant receptors (ORs), was not sufficient to reduce host seeking in the presence of carbon dioxide (CO2).

In this perspective, Group Mosquito Host Seeking Algorithm based Self-organizing (GMHSA) technique for genetic algorithm has been proposed.

Yet, for most species, nocturnal activity patterns of village entry and host seeking predominantly occurred before midnight indicating common behaviours across species and populations relative to human risk of exposure to Anopheles bites.

The study showed a wide distribution of host seeking tick species among the selected taluks, wherein Haemaphysalis spinigera was predominant in 3/5 taluks, Haemaphysalis bispinosa in 1/5 taluks, and both the species in 1/5 taluks.

Host seeking in the yellow fever mosquito, Aedes aegypti, and the African malaria mosquito, Anopheles coluzzii, relies on specific and generic host-derived odorants.

These findings indicate that indole and skatole are operating in a non-animal-host seeking context in Toxorhynchites and underscore the importance of understanding their roles in hematophagous mosquitoes.

This odorant is also a major component of flower scents and may play a role outside animal-host seeking.

ResultsTemporal and spatial distributions of over 15,000 mosquitoes, including males as well as unfed, host seeking, blood-fed, non-blood fed and gravid females were mapped.
