The larvae of the potato tuber moths can be very damaging to potato crops as well as tobacco and tomato plants. The larvae will eat away at the foliage and then proceed to eat away at the tubers as well, preventing the plant from growing. [4] At times, the larvae will eat through the potatoes themselves making them unsellable to consumers.
The main symptoms of Ditylenchus destructor, common to potatoes and its other hosts, are the rotting and discoloration of subterranean plant tissue. In potatoes, early infection can be detected by small white spots underneath the potato's skin. As the disease progresses, these spots become larger and darker with a spongy or hollow appearance. [7]
Click beetle larvae, called wireworms, are usually saprophagous, living on dead organisms, but some species are serious agricultural pests, and others are active predators of other insect larvae. Some elaterid species are bioluminescent in both larval and adult form, such as those of the genus Pyrophorus .

The pronotum and wing covers are covered in dense, short greyish hairs. The larva is known as a wireworm and lives in the soil. It is yellow, slender, stiff and leathery, and grows to a length of about 20 mm (0.8 in). The centre of the mandible has a small tooth for gnawing. [3]
Specifically, soft rot of potatoes can cause a huge decrease in yield, and is the most serious bacterial disease that potatoes are exposed to. For a grower of potatoes, there is a possibility that 100% of a whole season's yield could be destroyed due to insufficient conditions in a storage facility.

The economic damage from lesion nematodes is often underestimated because above-ground symptoms are not always obvious. No recent data are available regarding damage caused by these pathogens to this crop, but it is known that controlling them raises yields by between 8% and 40%, depending on the species of nematode and hybrid planted.
