Rapeseed, also known as rape, or oilseed rape, is a bright-yellow flowering member of the family Brassicaceae, cultivated mainly for its oil-rich seed, which naturally contains appreciable amounts of erucic acid. The term canola denotes a group of rapeseed cultivars which were bred to have very low levels of erucic acid and are especially prized for use as human and animal food. Rapeseed is the third-largest source of vegetable oil and the second-largest source of protein meal in the world.
The common asparagus beetle is an important pest of asparagus crops both in Europe and in North America. Asparagus is its only food plant. The beetle is 6.0 mm to 9.5 mm long and slightly elongated.

Delia flies are members of the Anthomyiidae family within the superfamily Muscoidae. The identification of different species of Delia can be very difficult for non-specialists as the diagnostic characteristics used for immature and/or female specimens may be inconsistent between species. Past taxonomic keys were not as comprehensive in their identification of Delia specimens; they were either too reliant on genetic characteristics, focused solely on a specific life stage, or were focused only on certain species. However current taxonomic keys aim to be more thorough by not only including morphological diagnostics for males, females, and immature specimens of various species, but also their genetic make-up or molecular barcode.
Brassica carinata is a species of flowering plant in the Brassicaceae family. It is referred to by the common names Ethiopian rape or Ethiopian mustard. It is believed to be a hybrid between Brassica nigra and Brassica oleracea.
Oxythyrea funesta is a phytophagous beetle species belonging to the family Cetoniidae, subfamily Cetoniinae.
Astylus atromaculatus is a species of beetle in the family Melyridae. It is variously known as the spotted maize beetle, or pollen beetle. It is indigenous to Argentina and neighbouring countries, but has been accidentally imported into various other regions such as the warmer regions of North America and much of Africa, where it has become invasive.
Pollen beetle is an informal term for any species of beetle associated intimately with suitably pollen-rich species of flowers. Typically such a beetle is adapted to the pollen as a major part of its diet. Species in at least sixteen families of the order Coleoptera could be counted as pollen beetles, and "pollen beetle" also is a common name for some such species.
Agriotes sputator is a species of click beetle, commonly known as the common click beetle. The adult beetle is brown and inconspicuous, and the larvae live in the soil and are known as wireworms. They are agricultural pests that devour the roots and underground parts of many crops and other plants.
Zygogramma exclamationis, commonly known as the sunflower beetle, is a species of leaf beetle belonging to the family Zygogramma. It is regarded as a pest of sunflower crops in North America.
Frankliniella schultzei, the common blossom thrips or cotton thrips, is a species of thrips in the family Thripidae. It is found in many parts of the world and is an important pest insect in agriculture.
Psylliodes chrysocephala or Psylliodes chrysocephalus, commonly known as the cabbage-stem flea beetle, is a species of leaf beetle situated in the subfamily Galerucinae and the tribe Alticini.
Trichobaris trinotata, commonly known as the "Potato stalk borer", is a species of weevil in the family Curculionidae. It is found in North America where it is a pest of potato plants, the larvae tunnelling inside their stems.
Epuraea is a genus of sap-feeding beetles in the family Nitidulidae, first described in 1843 by Wilhelm Ferdinand Erichson. There are at least 40 described species in Epuraea. Their most notable food source is sap but these beetles also feed on organic matter such as fruits, flowers, fungi, decaying plant tissue, and the tissue of dead animals. Epuraea beetles commonly overwinter underneath logs or in soil.
Afrogethes canadensis is a species of pollen beetle in the family Nitidulidae.
Afrogethes is a genus of pollen beetles in the family Nitidulidae. There are at least 2 described species in Afrogethes.
Meligethinae is a subfamily of pollen beetles in the family Nitidulidae. There are about 6 genera and about 10 described species in Meligethinae.
Sphenophorus parvulus, commonly known as the bluegrass billbug, is a species of beetle in the family Curculionidae. It is found in North America, especially in the eastern United States. It is a pest of Kentucky bluegrass, other grasses, corn and grain crops.
Brassicogethes is a genus of pollen beetles in the family Nitidulidae. There are at least 4 described species in Brassicogethes.
Malachius aeneus, the scarlet malachite beetle, is a species of soft-winged flower beetle in the family Melyridae. The beetle was introduced to North America in 1852, and is now widespread. The larvae are frequently found near cereal crops and are known predators of Brassicogethes aeneus in Great Britain.
