I ve always wonder each time I spray my house with insecticide,on most occasions I normally discovered that the cockroach would die with their stomach facing up.Have any one notices this or is there any scientific explanation to this.

I beieve most of these insecticides are organophosphate nerve poisons. The nerve poison often inhibits
cholinesterase, an enzyme that breaks down acetyl choline (ACh), a neurotransmitter. With extra ACh in the
nervous system, the cockroach has muscular spasms which often result in the cockroach flipping on its back.
Without muscular coordination the cockroach cannot right itself and eventually dies in its upside down-
position...

Below nairalanders is a clear example of what religion does to the brain and what science does. The first person I quoted is obviously mentally lazy, he does not know neither does he care to know. As far as he is concerned, only God knows. The second person I quoted is the opposite of the first person I quoted.

They are not dead! They are just wetin for the effects to wear off! If you wait long enough, for let's say 3 centuries you will be amazed at how dey will move again! They are just chilling on their backs cos it's much comfy that way.

Guy you've got it all wrong! These invertebrates don't have the complex central nervous system as higher animals! Their is no neurotransmitter or nervous system potentiating the propagation of action potentials in this organism.
Furthermore! AntiAcetylcholinesterases don't selectively pick out certain neural synapses to block! It's always all or nothing. A block will result in any of the following: fasciculations, floppyiness and paralysis not spasms or tremors.

Why humans no dey stand when dem die?

...forget all dis grammar. Na so dem dey die. Some ppl even say if their back touch ground, dem go die. They tend to develop paralysis & flip b4 they die...

Block of inhibitory neurotransmitter receptors would cause spasms or tremors.

I don't know if you were serious when you said they have no nervous system or neurotransmitters. They do..



And for the answer to the op, a Google search came up with:

"Cockroaches, apparently, have bulky bodies (composing of 3 heavy body segments) which are only supported by 6 long thin legs, As they die, they lose muscle-control causing the leg muscles to contract. As a result, the legs are forced to be pulled beneath the body causing them to lose their balance, and topple over. This also explains why cockroaches on the wall fall off when they were crawling on the wall and got sprayed with insecticides.

Is flipping over always the case?

No. There is still a possibility for a cockroach to die without toppling over. However, it is inherent upon these insects to involuntary experience muscle contraction and end up lying on their back upon dying."

grayht:
In summary, insecticides are poisons and it target a cockroaches nervous system. When you spray an insecticide, those neurotoxins cause tremors and muscle spasms, which flip it onto its back, and without muscle coordination, that’s the position it dies . Hope it helps
