Mosquito Life cycle
Knowing the different stages of the mosquito’s life will help you prevent mosquitoes around your home and also help you choose the right pesticides for your needs, if you decide to use them. All mosquito species go through four distinct stages during their life cycle:
- vEgg – hatches when exposed to water
- vLarva – (plural: larvae) “wriggler” lives in water; molts several times; most species surface to breathe air
- vPupa – (plural: pupae) “tumbler” does not feed; stage just before emerging as adult
- vAdult – flies short time after emerging and after its body parts have hardened.
Mosquito borne diseases in Thailand
Malaria is transmitted among humans by female mosquitoes of the genus Anopheles.
The Aedes aegypti mosquito can transmit the viruses that cause dengue fever. The female mosquito lays eggs in containers with water and plants near the home. It bites people and animals. This species can survive year round in tropical and subtropical climates.
Culex ( HoUSE MOSQUITO)
The virus causing Japanese encephalitis is transmitted by mosquitoes belonging to the Culex tritaeniorhynchus and Culex vishnui groups, which breed particularly in flooded rice fields.
Insect Repellent in Thai Market
DEET (chemical name, N,N-diethyl-meta-toluamide) is the active ingredient in many insect repellent products. It is widely used to repel biting pests such as mosquitoes and ticks.
Warning State! For children 6 months to 2 years, only concentrations of less than 10% DEET should be used, and only once a day. For children from 2 -12 years old, only concentrations under 10% should be used, and repellents should not be applied more than 3 times a day.
3-[N-Butyl-N- acetyl]-aminopropionic acid, ethyl ester, was developed by Merck & Co., Inc. IR3535® even controls insects via a mode of action which do not affect the insect. These positive attributes led to the use of IR3535® in many products developed specifically for children.
Warning State! IR3535 can be irritating to the eyes and may dissolve or damage plastics, but poses few other safety risks.
Citronella is one of the oldest and better known natural insect repellents on the market. Despite the fact that many people have heard of and trust citronella to help protect them against biting insects.
1. Due to the high volatility of citronella oil it evaporates quickly off the skin, making citronella’s staying power as a natural insect repellent very limited. It may work when first applied, but studies show that its stops working within an hour or less. This leaves you unprotected from biting insects very quickly.
2. Some countries have classified citronella as a hazardous substance because it is a skin sensitiser, causing an allergic reaction following contact with the skin.
A recommendation of the World Health Organization (WHO) for protection against mosquitoes that carry diseases, is not known to irritate skin and eyes, does not have a pungent odor, and does not dissolve plastics. It evaporates from the skin more slowly than DEET or IR3535 and may repel bugs for longer periods.
