As far as entomologists are concerned, insects do not have pain receptors the way vertebrates do. They don't feel 'pain,' but may feel irritation and probably can sense if they are damaged. Even so, they certainly cannot suffer because they don't have emotions.
Over 15 years ago, researchers found that insects, and fruit flies in particular, feel something akin to acute pain called “nociception.” When they encounter extreme heat, cold or physically harmful stimuli, they react, much in the same way humans react to pain.
Ants don't have complex emotions such as love, anger, or empathy, but they do approach things they find pleasant and avoid the unpleasant. They can smell with their antennae, and so follow trails, find food and recognise their own colony.
Summary: Scientists have known insects experience something like pain, but new research provides compelling evidence suggesting that insects also experience chronic pain that lasts long after an initial injury has healed.
Turns out ants don't really mourn or grieve or even have graveyards for the same reasons we as humans do. It all comes down to chemicals and smells and pheromones.
Do Ants Know If Other Ants Die? When an ant dies, the others do not notice straight away. They will just walk around it as if it was not there, but after three days, the ants will notice. After three days, the corpse will start decaying and it is at this point that it releases oleic acid.

Most likely, yes, say animal welfare advocates. Lobsters belong to a family of animals known as decapod crustaceans that also includes crabs, prawns, and crayfish.
While mammals and birds possess the prerequisite neural architecture for phenomenal consciousness, it is concluded that fish lack these essential characteristics and hence do not feel pain.
Dr. Rick Redak. Define scream. Insects do not have vocal chords or a voice.
Ants are similar to many other insects in that they possess senses such as hearing, touch and smell. Although hearing is very different in ants than animals that typically have ears, ants do possess the capability to hear.
Individual ants have tiny brains but together the many ants of a colony can exhibit remarkable 'intelligence'. Ants exhibit complex and apparently intelligent behaviour; they can navigate over long distances, find food and communicate, avoid predators, care for their young, etc.
In 2015, scientists published research11 that suggests some ants can recognize themselves when looking in a mirror.
Social insects like ants and honeybees are fastidious about their colony's tidiness. If any individuals die, they're quickly removed and thrown away in one of the nest's refuse tips.
While these insects don't literally scream, they actually produce sounds. Scientifically speaking, there are several species of ants that normally stridulate. These are shrill and repetitive sounds that are produced when the ants strike their body parts on certain areas of their colonies.
Many have the doubt that “does ants have brain?”, yes, they do have brain and it is very small that have 250,000 neurons. It is very less compared to human brain, but it is too large compared to other insect species. These ants have thinking ability and they can follow their routine with their colony.
Given that plants do not have pain receptors, nerves, or a brain, they do not feel pain as we members of the animal kingdom understand it. Uprooting a carrot or trimming a hedge is not a form of botanical torture, and you can bite into that apple without worry.
In 2008, the studies led to the finding that naked mole rats didn't feel pain when they came into contact with acid and didn't get more sensitive to heat or touch when injured, like we and other mammals do.
As explained by plant biologist Dr. Elizabeth Van Volkenburgh, all living organisms perceive and respond to painful touch, but plants do not perceive or “feel” pain the same way that animals do because they lack a nervous system and brain.
The wild wriggling and squirming fish do when they're hooked and pulled from the water during catch-and-release fishing isn't just an automatic response—it's a conscious reaction to the pain they feel when a hook pierces their lips, jaws, or body.
Ripping the legs off live crabs and crowding lobsters into seafood market tanks are just two of the many practices that may warrant reassessment, given two new studies that indicate crustaceans feel pain and stress.
Lobsters don't have vocal cords, and even if in agony, they cannot vocalise. The high pitched sound made by an overheating lobster is caused by expanding air rushing out of small holes in lobsters' bodies, like a whistle being blown. A dead lobster will “scream” just as loudly as if it was living.
It is advised not to squash ants, doing so will only release pheromones and trigger more ants to come to the location and cause more trouble to you and your family. Ants are known to pack a deadly bite that causes excruciating pain for a short time.
Ants, like other insects, have a heart that pumps hemolymph rhythmically.
Conceivably the trachea leading to an insect heart could all get blocked by something from the outside, which would be the closest thing to a 'heart attack' in an insect, but there's no record of that happening and its unlikely anyway. So, nope, no insect can have a heart attack.
