Question 1

managing malaria

Answer 1

ATTACK PARASITE IN THE HUMAN HOST
-anti malarial drugs, gelo stop infection
-don’t get bitten in first place, repellent, nets, long sleeve t-shirts trousers, education
-2021 malaria vaccine
-spraying incecticudes
-genetic engineering of sterile mosquitoes
-specially designed mosquito traps emit CO2
-reduce surface tension to hang from the surface of a still water source, oil breaks surface tension and drowns them
-bti bacteria grown in coconuts
-introduce larvae eating fish to paddy fields (muddy loach)
-flush reservoirs every 7 days
-eucalyptus trees planted to suck moisture
-empty out water storage cans
-spreading breeding grounds with ddt

Question 2

EFFECTIVNESS OF THINGS USED TO COMBAT MALARIA

Answer 2

-anti malarial drugs
❌harmful side effects
❌drugs can be expensive
❌dosent offer 100% protection

-don’t get bitten in the first place
❌expensive
❌nets are easily damaged

-malaria vaccine
✅vaccine trials have shown a large drop in children w malaria
✅no concerning side effects
❌false sense of confidence

INSECTICIDES IN HOUSES
-toxic
-oil based, discolourisation on walls

GENETIC ENGENEERING
-implications of removing mosquitoes from ecosystems and food chains

SOECIALLY DESIGNED MOSQUITO TRAPS
-lures mosquitos
-only effective on small scale

REDUCE SURFACE TENDION
-larvae cant come resistant to drowning
-oil is a pollutant

BTI BACTERIA
-cheap
-bti is environmentally friendly
-not much coconuts needed

LARVAE EARING FISH
-non toxic
-fish can be eaten, protein
-cheap
-cant eat all the larvae

FLUSH RESEVOIRS
-not all breeding grounds are reservoirs
-constantly repeated

EUCALYPTUS TREES
-not native, bad for water supply

DDT
mosquitos developed resistance
