Insects use pheromones to communicate with each other in two main ways. One is when insects such as ants leave a pheromone trail for other members of the colony to follow to a food source. The other way is to release pheromones to indicate when they have found food; bees and some others use this method.
It doesn't kill the insect and isn't harmful to humans. The pheromones just disrupt the reproductive cycle of the harmful insects.
To attract mates and to warn or guide other insects.

No, the attractant is natural substance.
The green colored chemical that traps light is called Chlorophyll.
Harmful plants can be carnivorous or poisonous, Carnivorous, Pitfall traps (Pitcher plant), Flypaper traps, Snap traps, Bladder traps, Lobster - pot traps Poisonous plants, there are many poisonous plants, please see related link for more information.
Chlorophyll is the pigment in plants that traps energy from the sun using photosynthesis.

no there were no venus fly traps. but there where paintings.
On using biological controls such as pheromone traps, the possibility of development of resistance is avoided. Moreover, the bio insecticides are eco friendly ( using chemical insecticides causes alkalinity or acidity of the soil. )
We recommend using gel baits, non-repellent insecticides, dust baits, roach bait stations, insect growth regulators (IGR), select dust and roach pheromone traps for residential and commercial areas. Very often, high levels of control can be achieved by baits alone for the typical homeowner.

Whiteflies can be trapped using simple yellow sticky traps, they are attracted to the color.If you are referring to citrus leafminer, these can be trapped using sticky traps with pheromone lures. You can find these here: www.iscatech.com/shop

Insecticides and pheromone traps may be used outside to control the Asian lady beetle [Harmonia axyridis], which also is called the Japanese ladybug. Inside, the controls tend to be sealing entry points and vacuuming. But these means may be supplemented by others. Research still is ongoing regarding the possible use of natural enemies. In terms of natural enemies researchers particularly are investigating the possibilities of disease carrying mites and fungi.

By serving as bait by which the affected insects are trapped is the way in which pheromones can be used as insecticides. Insecticides are used to control insect populations. Pheromones are excretions or secretions by which insects of a certain kind communicate information to other members of that same kind. The information may range from threats, sexual rendezvous, mass meeting places and times, food trails, and more. So for example, a pheromone may be released to guide insects to what they think will be willing food sources. Instead, it leaves them in a sticky trap.
Chloroplast traps light energy and converts to chemical energy
it traps the energy from the sun and changes it into chemical energy that plants use.
These substances are called chlorophylls.
