Bactericera cockerelli, [1] also known as the potato psyllid, is a species of psyllid native to southern North America. Its range extends from Central America north to the American Pacific Northwest and parts of Manitoba , in Canada .
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]
Potato cyst nematodes are important economically due to the fact that they can substantially reduce crop yields. Globodera pallida are able to cause 80% yield loss in a potato field if left untreated. [8] On a more global scale, the Australian potato industry is worth about AUD$500 million yearly which equates to $340 million U.S. dollars. [7] [9]
Fusarium dry rot of potato is a devastating post-harvest losses (vegetables) disease affecting both seed potatoes and potatoes for human consumption. [3] Dry rot causes the skin of the tuber to wrinkle. The rotted areas of the potato may be brown, grey, or black and the rot creates depressions in the surface of the tuber.
It causes the disease corky ringspot in potatoes. The disease manifests in various ways, and signs can include brown rings and arcs on the surface of a potato, and discolored spots on the interior. [1] Nematodes of the family Trichodoridae, the stubby-root nematodes, are vectors of the virus.
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 .
