Resistance to DDT is also widespread.

3.3 Efficacy of DDT and related resistance management practices

Two types of resistance to DDT are generally recognized (i) specific resistance developed directly in response to the use of DDT, and (ii) cross resistance (non specific resistance) as a result of the development of resistance to other insecticides such as pyrethroids.

Burets are used to titrate liquids. A buret is filled with a specific volume of a liquid, and placed beneath it is a container such as an Erlenmeyer flask. By opening the valve on the buret, the liquid in the container will then be titrated. High quality burets have a venting mechanism with which they can be very easily refilled with the exact volume for which the buret is calibrated.

Of the eight countries reporting use of DDT through the questionnaire, three reported data indicating the presence of resistance to DDT.

And you put a drop, in this case, of urine at the bottom.

You know the Hindus are killing us Muslims. Be careful.

In areas with DDT resistance, residual spraying programmes can no longer rely on the use this insecticide.

Two main opportunities exist through which current reliance on DDT may be reduced in a sustainable manner, where DDT is currently used for indoor residual spray

And I created a little oil spill in the Gulf of Mexico.

Ticktock.

Mexico has prepared the revised specific technical guidelines on DDT.

Recorded Voice Tick, tick, tick.

In areas with cross resistance between DDT and pyrethroids, it has been demonstrated that pyrethroid treated nets remain effective in preventing malaria. In such circumstances, the use of insecticide treated nets (ITNs) is a viable alternative to the use of DDT or pyrethroids for indoor residual spraying.

Your stomach? Yeah, my stomach's bad, too.

Ticktock. Ticktock.

Pige? Pige?

Where non specific resistance develops, it is likely that both DDT and all other pyrethroids could become ineffective for malaria control.

Today there are still three million HIV positive people in India.

The first step in reducing current reliance on DDT is to improve the capacity of local malaria vector control programmes to determine where and when DDT is needed and how much of it is needed.

The time passed,

Couldn't you use DDT?

According to the DDT register, three countries have notified use of DDT in disease vector control and one country notified the intention to use DDT if necessary.

3.4 Current Management of DDT

Effective regulation and control of DDT as recommended by WHO (Section 6) will require a conducive policy and institutional framework that enable intersectoral action to prevent the diversion of DDT for non recommended use and improve accountability.

If you put one drop, one drop of something, in that water, it'll change it forever.

Drop by drop, the water can conglomerate into a lake.

One tear for you. One for me.

And with these types of antibodies, we know humans can make them.

But DDT sprayed on local homes, there's nothing better to eliminate malaria, besides insect DDT impregnated mosquito nets.

Okay, we could talk about Rachel Carson and DDT, but we know it wasn't good for you and me.

Evaluation and reporting mechanisms relating to DDT

But they forgot this the fact that birds dine on grubs, that robins eat lots of worms now saturated with DDT.

This reversal has already happened in South Africa, where an unanticipated return of a vector, that has acquired resistance to the alternative insecticide, resulted in outbreaks of malaria, forcing a reintroduction of DDT.

So, in this device the idea is that you drip the bottom end of it in a drop of, in this case, urine.

Is that a fact?
