- Most hot peppers and some sweet peppers require insect pollination to form fruit. If the proper insect is absent, or if the local insects are not attracted to your pepper flowers, you may see the plants flower, drop off and never set fruit.

A video by someone growing pepper plants, before and right after a heat wave. During the heat, flowers fell off, but after the heat, new flowers formed. The same happened to his tomato plants.
