The Wikipedia article on this strategy "has multiple issues", and the "How push pull works" section "does not cite any references or sources." A basic description is as follows:
"It is based on in-depth understanding of chemical ecology, agrobiodiversity, plant-plant and insect-plant interactions, and involves intercropping a cereal crop with a repellent intercrop such as Desmodium uncinatum (silverleaf)[3] (push), with an attractive trap plant such as Napier grass (pull) planted as a border crop around this intercrop. Gravid stemborer females are repelled from the main crop and are simultaneously attracted to the trap crop. Napier grass produces significantly higher levels of attractive volatile compounds (green leaf volatiles), cues used by gravid stemborer females to locate host plants, than maize or sorghum...However, many of the stemborer larvae, about 80%, do not survive, as Napier grass tissues produce sticky sap in response to feeding by the larvae, which traps them, causing their mortality. "
Perhaps some researchers can comment on how exactly certain volatiles released by plants can affect pest behavior?

@Abdallah M. Albeltagy
What do you mean by "lenses"? Are you referring to robotic devices that could differentiate between weeds and economic crops? I was asking more in regards to certain chemicals released by plants which repel / attract pests, as referenced here:

Dear Jacob,
there are a lot of very good reviews and articles available discussing push & pull strategies and insect behaviour. Some of them also compare success of pest control in conventional and integrated agricultural strategies including saving of pesticide use.
Some suggestions:

of course, push-pull is definitely help n repelling-trapping insect pests, but whether it will adversely affect natural enemy population is the question.The kairomones emitted by the push-pull crops may repel the natural enemies too!
