By Amy Grant

If you are growing pepino melons, as with any crop, you may be having some trouble with pepino melon pests and wondering “what’s eating my pepino melon.” With their sweet, pleasant flavor, it’s no wonder that pests are frequent visitors on these melons, but you need to identify them in order to treat them. Read on for help with that.

What is Eating My Pepino Melon?

A relative rarity in the United States, but attaining some popularity, is the pepino melon. Native to the Andean region of South America, these small fruit are not actually melons at all but members of the nightshade family. Thus, the insects that feed on pepino melons are generally those that feed on members of the Solanaceae family, which includes tomatoes, potatoesand eggplant.

Pepino melons are delicious with a taste like honeydew melon and cantaloupe. Popular in New Zealand, Australia and Chile, this warm season plant can survive short periods of temps down to 28 F. (-2 C.) and with its small size thrives in containers. This means that it can be grown in a broader area since the plant can be protected or taken indoors or in a greenhouse when temperatures take a nose dive.

Technically, pepino melons are perennials, but they are usually grown as annuals due to their sensitivity not only to cold temps but to diseases and pests as well. As mentioned, insects that feed on pepino melons are also those attracted to other Solanaceae family members. So if you are looking for information on pepino melon pests, look no farther than those drawn towards eggplant, tomatoes and potatoes.

Pests likely found on pepino melon may include:

Fruit flies love pretty much everything, and pepinos are no exception. Pepinos grown in greenhouses are particularly susceptible to attack from aphids, spider mites and whiteflies.

Preventing Pests on Pepino Melon

As with anything, a healthy plant is more likely to withstand a mild insect or disease attack. Plant pepino melon in full sun to partial shade in a frost free area that is sheltered from wind, ideally next to a southern exposure wall or on a patio. Plant pepino melons in fertile, well-draining pH neutral soil (6.5-7.5). Mulch around the plants to suppress weeds and retain moisture. Debris and weeds may harbor insects, so it is important to keep the area around the pepinos free from them.

Pepinos can be trained to grow up a trellis to maximize garden space. The plant’s root system is spread out and shallow, so pepino melons are sensitive to moisture stress and not at all drought tolerant. This means you should water regularly.

Prior to transplanting, amend the soil with some well-rotted manure a few weeks in advance. Thereafter, fertilize as you would a tomato with a 5-10-10 fertilizer as needed. If the plant is being trained on a trellis, then some light pruning is in order. If not, there is no need to prune. To prune the plant, treat it as a tomato vine and prune only to open the plant up to light, which will help increase the size and quality of the fruit as well as making harvesting easier.
