Bedbug nymphs protect themselves with such a pheromone, which has a specific mixing ratio of the aldehydes -2-hexenal, -2-octenal and 4-oxo--2-hexenal, against mating attempts by male bedbugs. The latter directly drills a hole into the abdomen of sexually mature female bedbugs and injects its sperm there ( traumatic insemination ).
Plants can protect themselves from abiotic stress in many different ways, and most include a physical change in the plant’s morphology. Phenotypic plasticity is a plant’s ability to alter and adapt its morphology in response to the external environments to protect themselves against stress. [ 2 ]
Humans standing in the vicinity of nests are almost always attacked and experience painful bites. [23] The bees also crawl over the intruder into the ears, eye, mouth, and other cavities. [ 25 ] The Trigona workers give a painful and persistent bite, are difficult to remove, and usually die during the attack.

In plant morphology, thorns, spines, and prickles, and in general spinose structures (sometimes called spinose teeth or spinose apical processes), are hard, rigid extensions or modifications of leaves, roots, stems, or buds with sharp, stiff ends, and generally serve the same function: physically defending plants against herbivory.
Plants that cause illness or death after consuming them are referred to as poisonous plants. The toxins in poisonous plants affect herbivores, and deter them from consuming the plants. Plants cannot move to escape their predators, so they must have other means of protecting themselves from herbivorous animals.

This relationship can be seen in other species of flowering plants and pollinating insects, but a more distinct example is the coevolution of ants and acacias. The acacia ant (Pseudomyrmex ferruginea) is an insect that has been discovered to protect five different species of acacia trees. The ant provides protection to the plant while the ...
