Question

1. explore: when using caterpillar - resistant corn, does it help to add insecticide? explain

Explanation:

Step1: Consider pest - control factors

Caterpillar - resistant corn has traits to resist caterpillars. However, there may be other pests not targeted by the resistance traits. Also, the resistance may not be 100% effective against caterpillars.
Adding insecticide can provide additional protection against a wider range of pests and can enhance the control of caterpillars in case the corn's resistance is not sufficient.

Step2: Weigh the pros and cons

On one hand, using insecticide can improve pest control. On the other hand, it can have negative environmental impacts such as harming non - target organisms and contributing to pesticide resistance in pests over time. But from a pure pest - control perspective for the corn crop in question, it can help.

Answer:

Yes, it can help. The caterpillar - resistant corn may not be completely effective against caterpillars and may not target other pests, so insecticide can provide additional protection.
