Could Plants be Able to Avoid Herbivores by Producing Odor?

An insect eating the leaf, illustration only.

I sometimes wonder why plants could survive with a lot of herbivores live around. The answer, actually relationship between plants and herbivores is like cat and mouse in some degree.

Both relationships, cat – mouse and plants – herbivores are survives, and they goes through evolution process in long time, may be thousand years.

Long long time, we might know that plant have methods (adaptations) to protect themselves from eaten by herbivores, some are:

- barrier such as a waxy cuticle and bark
- modified branches such as thorns
- hard shells
- modified leaves such as spines.

Interestingly, recently, scientists found that plants have strategy to produce camouflage odors or produce similar odor of other plants to:
- confuse herbivores.
- not easily to be identified by herbivores.
- not be able to be located by hungry insects
- carry information in plant communities

Nature work so wonderful, do you believe it?

  1. That's why I leave all the plants alone and just eat meat :-))

  2. A natureza é maravilhosa. Defende-se a si mesmo. Até da "mão" do homem...em muitos casos

  3. My first thought for defense was thorns & nasty taste. I never thought of odor, but so logical.

  4. ...deer have very sensitive noses and don't like to eat plants that have odors that they find undesirable.

  5. The wonder of nature has helped my husband and I cope with the Covid isolation. We could walk along the boardwalk here and observe. It really helped us cope.

  9. Hello,
    It is interesting that odors can keep the insects away from our plants. I heard peppermint oil can keep the bugs away. Take care, Enjoy your weekend!

  10. Some plants are easily infested with pests while other plants will deter pests with their odor.

  12. Yeah, I believe this. . It's often thought that plants can't react to their environment, but that's not true. Plants react to light, to smells, to flavourings and also to contact. A good example of the reaction to contact is the plant Mimosa pudica - herb stir me-not. /- touch-me-not, (sorry I do not knows the name in english) but hhen you touch the plant, it folds its leaves at lightning speed. The plant cannot think, but it can react to certain stimuli.When an insect eats from a plant, saliva enters the wound. This saliva, which possibly causes a pre-digestion of the food, contains a substance that triggers the plant reaction by giving off an odour signal.

    In a dutch nature book of mine contained this example of plants communicating with animals. Flowers produce smells that attract pollinators like bees. After pollination, many flowers stop producing fragrances. The floral scent is beneficial for the plant that uses it to attract pollinators and also for the pollinator that gets nectar and pollen as rewards. Plants also communicate with bodyguards who turn them on when they are attacked by herbivores. Plants damaged by plant-eating insects produce odorants that act as SOS signals. In this way they attract predatory insects such as parasitic wasps and predatory bugs and they free the plant from their attackers. So every organism has its own transmitting and receiving installation. Nature is all about making the right decision. And that's the way it is in our lives, isn't it?

  14. Tanza, Nature is alway entertaining and interesting. Disguise, odor, poison secretions, physical defense...all adaptations for defense and survival. Stay Safe and Take Care, Big Daddy Dave
