The origin and significance 1
.The mosquito vectors of dengue fever Aedesaegypti important in breeding of mosquito. มักจะพบ in the receptacle, drinking water, water. Household, from dish cabinet legs together, both based on ant water locked in household.Aegypti phase 3 include various types of detergent (detergent) alum, vinegar, salt, and และด่างทับทิม, the results showed that proper concentration of mosquitoes phase 3 has 100% of melting the question types. Is 0.04% alum solution is 6.08% vinegar solution is 0.5% salt solution is 1.00% aqueous potassium permanganate is 0.When the concentration of the solution 08% sort households use to get rid of mosquitoes phase 3 from least to most, as follows: detergent, potassium permanganate. Vinegar, salt and alum, if put into drinking water.6.And 08% wastewater should be put 0 detergent solution.08% and other household substances, namely, vinegar, salt and potassium permanganate is appropriate, so we can see that the substance household. As mentioned above, can eliminate mosquitoes phase 3.
1, aim. To study the properties of chemicals that affect the removal of mosquitoes, 2
. To compare the chemicals used to get rid of mosquitoes
, 1 hypothesis. Different types of chemicals could affect the removal of mosquitoes have
2.Detergent could affect the removal of mosquitoes can best
variables. Chemicals
dependent variable volume water less man up.
control variable quantity of chemicals used, man place and period definition operational
.The chemicals are detergent, potassium permanganate, alum, salt and vinegar by ลูกน้ is reduced.
quantity is when the chemicals on the breeding mosquitoes and ทำให้ปริ man mosquitoes reduced or disappear
.The amount of chemicals is to use the volume number rate
a chemical place is, according to the place with water locked room water bath time is 10 day
A, put 5 times
.
