Trap crops are plantings that are used to attract the insects to them so they keep away from other crops. It has been recommended to use trap crops when growing many things such as broccoli, cabbage, cauliflower, cucumbers. potatoes, and green peppers.
When growing squash those three mentioned varieties hubbard, buttercup, or giant pumpkins have been found more attractive to squash bugs and also the cucumber beetle than other varieties so they will mostly go to them first. In large field plantings outer perimeter rows of those host crop are planted set off from the main crop. When the bugs migrate in from the field edges they concentrate in the trap crop and then can be exterminated there minimizing maincrop losses and pesticide use.

Usually trap crop is a plant that attracts agricultural pests, usually insects, away from nearby crops. This form of companion planting can save the main crop from decimation by pests without the use of pesticides. Trap crops can be planted around the circumference of the field to be protected, or interspersed among them, for example being planted every ninth row. Trap crops, when used on an industrial scale, are generally planted at a key time in the pest's lifecycle, and then destroyed before that lifecycle finishes and the pest might have transferred from the trap plants to the main crop
There have been lots of research articles written on trap cropping for over the last ten years. Even some youtube videos have been made.
