Mosquito adults are small, flying, midgelike insects. Female mosquitoes can be differentiated from similar insects by the presence of a long slender proboscis that is adapted for piercing skin and sucking blood, and long slender wings that are covered with small scales. Male mosquitoes have scale-covered wings, but their probosces, or beaks, are shorter and thicker than the females', and are adapted for sucking plant juices and other sources of sugar rather than blood. In the immature stages, called larvae or wigglers, mosquitoes are usually black or dark brown and occur in nonmoving or nearly still water. Most mosquito larvae have a distinctive siphon or air tube at the rear of their bodies. The next stage is the pupal stage; pupae, called tumblers, are also aquatic and are small, roundish forms, usually black in color.

Common local mosquitoes
Up to the present, we have found 70 kinds of mosquitoes in Hong Kong. The most common kinds are Aedes Albopictus, Anopheles Minimus, Anopheles Jeyporiensis, Culex Pipiens Quinquefasciatus, Aedes Togoi and Culex Tritaeniorhynchus. **(Picture source: FEHD)

Life Cycle
The life cycles of mosquitoes vary widely from species to species. Some female mosquitoes lay single eggs on water surfaces; others lay single eggs on moist soil where later flooding is likely. Still other species lay batches of eggs, called rafts, 100 or more at a time on water surfaces. Eggs deposited on water surfaces usually hatch within a day or so, but eggs laid on soil surfaces do not hatch until flooding occurs, which may be months or even years later. Larvae, which are nearly invisible to the naked eye, hatch from eggs. Larvae molt three times to become 4th-stage larvae. Several days later, this larval form molts again to become a pupa. Adult mosquitoes emerge from pupae 1 to 2 days after that, with male mosquitoes always emerging first. In summer the entire life cycle, from egg to adult, may be completed in a week or less.

Communicable diseases
Female mosquitoes of nearly all species require blood from vertebrate animals to develop eggs, and many species bite people, pets, and livestock for this purpose. The most important consequence of this is the transmission of microorganisms that cause diseases.

Dengue Fever (Causative agent )

Dengue fever is an acute mosquito-borne infection caused by the dengue viruses. This is found in tropical and sub-tropical regions around the world. For instance, dengue fever is an endemic illness in many countries in South East Asia. The dengue viruses encompass four different serotypes, each of which can lead to dengue fever and dengue haemorrhagic fever...click for more details

Japanese Encephalitis

What is Japanese encephalitis Japanese encephalitis is a mosquito-borne disease caused by the Japanese encephalitis virus. The virus is transmitted by the bite of infected mosquitoes . The principal type of mosquito that transmits the disease is called Culex tritaeniorhynchus. The disease occurs mainly in the rural and agricultural areas of Asia and the Western Pacific Region. It is a rare disease in Hong Kong. There are less than 10 cases reported in the past ten years...click for more details

Malaria (Causative agent )

Malaria is a serious and sometimes fatal disease caused by a group of malaria parasites, namely Plasmodium vivax, Plasmodium falciparum, Plasmodium ovale, and Plasmodium malariae. It is commonly found in many parts of tropical and sub-tropical areas where the climate is warm, like Africa, South-East Asia and South America...click for more details

Management

There is no better defense against mosquitoes than a tailor-made treatment plan from Johnson Group

Mosquito control is accomplished by searching out mosquito larvae in standing water and treating the water with a material that kills the larvae. Many materials currently in use are biological in origin and are highly specific for mosquitoes, with little or no effect on other organisms.

Sanitation Practices

Structure
Mosquitoes found inside a building have entered from the outside in almost all cases. Therefore, barriers preventing access to the building are the first line of defense. Cracks around windows and doors where flies may enter should be sealed. Well-fitted screens will also limit their access to buildings.

Inovative Devices

Physical devices
Install suitable physical devices like Fly Trap will be the most Eco friendly solutions for fly control. Outdoors, you may consider any type of Outdoor Electric Insect Killer or Mosquito Killing Machine, but for indoors and other sensitive areas like kitchen or food processing areas, please use only Sticky Pad Indoor Insect Killers.

	Starkeys® Australia L25 Outdoor Model. Totally weather proof (water tested IXPx4 rated) with powerful light and heavy duty power transformer. 0.5 hectare range.
	Starkeys® Australia Decore Sticky Pad Indoor Insect Killer. NO noise, NO smell, NO debris, NO pollution and NO chemicals. 80sq.m. range.
	The Arctic MKS ADVANCE is a scientific breakthrough in controlling mosquitoes. It uses carbon dioxide (CO2) to mimic respiration and body temperatures of humans, horses, livestock, poultry and domesticated pets. The Arctic Mosquito Killing System acts as a magnet to attract mosquitoes, and then vacuums them into the unit where they are quickly and quietly eliminated.

Bug Defence™ Automated Misting System

Bug Defence™ provides an effective insect mist barrier along the perimeter of protected areas with immediate results. The automated misting system is computer controlled. You can preset your preference time and the system will then spray automatically at the precise rate and time.

Bug Defence™ provides an effective Insect Mist Barrier along the perimeter of protected areas with Immediate results. The Bug DeFence™ Solution is an all-natural, concentrated formulation of essential oils blended with complementary surfactants, and oil-specific synergists. Its gentle lemon scent provides a long-lasting deterrent to biting insects.

The patent concentrated formula is diluted with water before misting. It's a colorless, non-staining liquid that is safe to use around outdoor furniture. It contains no alcohol or toxic chemicals, is non-flammable, and biodegradable.

Developed and further validated through University Entomologists and Independent research facilities, the active ingredient “Geraniol” found within Bug DeFence™ has proven to be the most effective repellent of the over 4000 compounds tested by the University of Florida including Citronella and 10% Deet.

Thermal Fogging Machine and Cold-mist Machine

(Thermal and cold fogging are particularly useful in dealing with large population of mosquito adults)

Thermal Fogging

Thermal fogging is a space treatment against flying adult. It can reach air spaces in areas obstructed by dense vegetation or other objects. When the flies come into contact with the droplets (usually in 5-30 micron), they will be killed immediately.

Cold-mist Fogging

SOLO® 444 Cold-mist Blower	Fog Master® ULV Fogger

Cold fogging is a space treatment against flying adult. Though It cannot reach air spaces in areas obstructed by dense vegetation or other objects, it is easily to control its distance and coverage, and is more suitable to apply in urban areas. When the flies come into contact with the droplets (usually in 5-30 micron), they will be killed immediately.

Larvicidal oil or Anti-malarial oil

It is a petroleum distillate, when applies directly to water bodies, it will form a thin film on the water surface and kill larvae and pupae by suffocation.

Bacillus thuringiensis subsp. israelensis (Bti)

The bacterium Bacillus thuringiensis subsp. israelensis (Bti) infects and kills mosquito larvae. It must be consumed by the larvae and acts as a stomach poison, damaging mid-gut cells of mosquito larvae. It is highly selective, killing only mosquitoes and larvae of a few other related flies. Bti can be categorized as green product because it is environmentally friendly.

S-Methoprene

S-Methoprene inhibits the development of larvae. It is more effective in the late larval stage. S-Methoprene can be categorized as green product because it is environmentally friendly
