The gray sunflower seed weevil Smicronyx sordidus is a species of weevils from a family of Curculionidae.
Adult beetles are 8 millimetres (0.31 in) long, and pale gray.
The species life cycle is only a year long. Both sexes eat sunflower buds, and often before they open. Sometimes they eat plant tissues. Females like the flowers whose buds are about to hatch, therefore, they can lay their eggs at the bottom of the seed. When they hatch, a larva emerges from them, destroying the seed from inside. On the later stages the larvae exit the seeds by dropping to the ground, where they hide during winter time. They reproduce every June. [1] [2]
Lythrum salicaria or purple loosestrife is a flowering plant belonging to the family Lythraceae. It should not be confused with other plants sharing the name loosestrife that are members of the family Primulaceae. Other names include spiked loosestrife and purple Lythrum. This herbaceous perennial is native to Europe and Asia, and possibly Australia.
Helianthus is a genus comprising about 70 species of annual and perennial flowering plants in the daisy family Asteraceae commonly known as sunflowers. Except for three South American species, the species of Helianthus are native to North America and Central America. The best-known species is the common sunflower. This and other species, notably Jerusalem artichoke, are cultivated in temperate regions and some tropical regions, as food crops for humans, cattle, and poultry, and as ornamental plants. The species H. annuus typically grows during the summer and into early fall, with the peak growth season being mid-summer.
Centaurea solstitialis, the yellow star-thistle, is a species of thorny plant in the genus Centaurea, which is part of the family Asteraceae. A winter annual, it is native to the Mediterranean Basin region and invasive in many other places. It is also known as golden starthistle, yellow cockspur and St. Barnaby's thistle.
Cosmopolites is a genus of true weevil in the Dryophthorinae subfamily and tribe Sphenophorini. The type species and most economically important is the banana weevil Cosmopolites sordidus.
Bruchidius villosus is a species of bean weevil known by the common names broom seed beetle and Scotch broom bruchid. This beetle is used as an agent of biological pest control against the noxious weed known as Scotch broom.
Exapion fuscirostre is a species of straight-snouted weevil known by the general common name Scotch broom seed weevil. It is used as an agent of biological pest control against the noxious weed known as Scotch broom.
Larinus is a genus of true weevils, comprising about 180 species, mostly in the Palaearctic region with some species introduced to North America. Turkey appears to have a significant diversity of the group, with more than 50 species recorded in the eastern part of the country.
Bangasternus orientalis is a species of true weevil known as the yellow starthistle bud weevil. It is used as an agent of biological pest control against the noxious weed yellow starthistle.
Eustenopus villosus is a species of true weevil known as the yellow starthistle hairy weevil. It is used as an agent of biological pest control against the noxious weed yellow starthistle.
Fulvous is a colour, sometimes described as dull orange, brownish-yellow or tawny; it can also be likened to a variation of buff, beige or butterscotch. As an adjective it is used in the names of many species of birds, and occasionally other animals, to describe their appearance. It is also used as in mycology to describe fungi with greater colour specificity, specifically the pigmentation of the surface cuticle, the broken flesh and the spores en masse.
Larinus planus is an insect of the Curculionidae family. They are oval shaped, dark brown or black, and about 5–10 millimetres long. While native to Europe, it is also common in North America. It feeds on floral buds, primarily of thistles, with the larvae stage being the most destructive to them. In North America, it has been used as a biocontrol agent. It is also known as Larinus carlinae.
Lixus concavus, commonly called the rhubarb curculio, is a species of weevil. Rhubarb is a host, together with dock, sunflower, and thistle.
Oxyops vitiosa is a species of weevil in the family Curculionidae. Common names include the melaleuca leaf weevil and the melaleuca snout beetle. It feeds on the leaves and shoots of the broad-leaved paper bark tree, Melaleuca quinquenervia, which is endemic to Australia where it grows on seasonally inundated plains and swampland, and was introduced into Florida in order to help drain flooded portions of the Everglades.
Smicronyx fulvus, commonly known as the red sunflower seed weevil, is a weevil in the family Curculionidae.
Smicronyx is a genus of true weevils in the beetle family Curculionidae. There are more than 220 described species in Smicronyx, found worldwide.
Odontopus calceatus is a species of weevil which occurs in much of the eastern and southeastern United States. Its range is as far north as Massachusetts all the way south to the Gulf of Mexico, and from the Atlantic westward to the Mississippi River. Common names include yellow poplar weevil, sassafras mining weevil, tuliptree leafminer, tulip tree weevil, or the magnolia leaf miner.
Apion apricans is a species of seed weevils native to Europe. It is widespread everywhere. Damages clover and wild. The beetle is 3–3.5 mm in size, black, with a metallic hue, the body is pear-shaped, the legs are partially yellow; rostrum long, almost straight; apex of antennae black, base - red. Egg - 0.3-0.5 mm, yellowish, long, smooth. Larva 2–2.5 mm, white with a creamy hue, curved, dark brown head, on the upper jaws on each side of three growths, the middle of them increased; instead of legs six pairs of small knolls. Pupa 3–3.5 mm, yellowish white.
Tychius sordidus is a species of leguminous seed weevil in the beetle family Curculionidae. It is found in North America.
Nealiolus curculionis is a species of parasitic wasp in the family Braconidae. It is a parasitoid of the sunflower stem weevil Cylindrocopturus adspersus, and a number of other species of stem-boring weevils.
A storage pest is an insect or other animal that damages or destroys stored food or other stored valuable organic matter. Insects are a large proportion of storage pests with each type of crop having specific insects that gravitate towards them such as the genus Tribolium that consists of insects such as Tribolium castaneum or Tribolium confusum which damage flour crops primarily.
