The abdomen is brownish black, the wing covers reddish brown tinged with yellow, and the antennae and legs are pale reddish brown. 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).
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 .

Use of tomato leaves as an herbal tea has been responsible for at least one death. [35] Leaves, stems, and green unripe fruit of the tomato plant also contain small amounts of the poisonous alkaloid tomatine, [36] although levels are generally too small to be dangerous. [36] [37] Ripe tomatoes do not contain any detectable tomatine. [36]
P. zeae populations can be controlled through by weed-free fallow. [8] A few nematicides are labeled for use on sugarcane. Mocap (ethoprop) and telone products are common nematicides used in Florida to control wireworms and also labeled to control plant parasitic nematodes. [5]
A sign of black dot disease is black microsclerotia that are produced by the pathogen, and can be found on the roots, the tuber, the stems, and the leaves. [3] This can be used to diagnose black dot. Symptoms of black dot disease include silvery lesions on the surface of the tuber, brown or black lesions on the leaves, leaf wilting, and ...
