Life Cycle of a Mosquito

R 169

Description

The Life Cycle of a Mosquito is self-explanatory, taking you from the birth of a Mosquito to their adult life.

Mosquitos (scientific name is Culicidae) begin life in the water, where their eggs are laid in floating rafts. The larvae that emerge feed on organic material in the water while developing into pupae. Days later, an adult mosquito emerges from the water, waits for its wings to dry, and flies off.

As adults, only females drink blood; males are only interested in mating.  In South Africa, there are interesting experiments in controlling the spread of Mosquitos by providing them with contraception.

Dimensions: from wing tip to wing-tip are 10cm and the plastic is non-toxic and BPA free.

Experimental biocontrol methods

Introducing large numbers of sterile males is another approach to reducing mosquito numbers. This is called Sterile Insect Technique (SIT).[16] Radiation is used to disrupt DNA in the mosquitoes and randomly create mutations. Males with mutations that disrupt their fertility are selected and released in mass into the wild population. These sterile males mate with wild type females and no offspring is produced, reducing the population size.[17]

Another control approach under investigation for Aedes aegypti uses a strain that is genetically modified to require the antibiotic tetracycline to develop beyond the larval stage. Modified males develop normally in a nursery while they are supplied with this chemical and can be released into the wild. However, their subsequent offspring will lack tetracycline in the wild and never mature.[18]
