• genus
  • The first new species described is placed in the genus Diaprepes , which is still found in the Caribbean today, and given the specific name squamula , meaning scaly, in reference to the dense scaly covering of the Weevil. (com.es)
  • The second species described is placed in the genus Lachnopus , also still found in the Caribbean today, and given the specific name serraticrus , meaning 'toothed-leg', in reference to a pattern of prominent serrations on the Insect's tibia. (com.es)
  • The third new species described is placed in the genus Apodrosus , another modern Caribbean genus, and given the specific name tinctocorpus , meaning 'dyed body' in reference to the colour of the body, which brown-black and lacks any markings. (com.es)
  • The fourth new species is also placed in the genus Apodrosus, and given the specific name canalinasus, meaning 'grooved-nose' in reference to a distinctive furrow on the snout. (com.es)
  • The fifth new species described is placed in the genus Promecops , today found in the Caribbean, as well as in Central and South America, and given the specific name divarichela , meaning 'spread-apart claws', in reference to the free tarsal claws. (com.es)

  • eggs
  • In field trials using the same four species established as spaced plants L. bonariensis laid more eggs per tiller in ryegrass in a low altitude pasture site than in ryegrass in a higher altitude site. (frontiersin.org)
  • No eggs were found on the three native grass species at the tussock sites, and only low numbers were found on other grasses at the low altitude pasture site. (frontiersin.org)
  • Female bean weevils lay eggs onto seed pods, or into them by chewing holes, in groups of 2 to 20 eggs. (wikipedia.org)
  • Temperatures higher or lower than this can cause a decrease in the number of eggs lain and they are very vulnerable to temperatures below 0 °C. This limits the species to how far north it can spread, and is found only as far north as northern Lithuania, with some being found in south-west Siberia. (wikipedia.org)
  • genera
  • At present eight genera and 18 species of entimines are reported for Puerto Rico and adjacent islands (O'Brien & Wibmer 1982, 1984, Wibmer & O'Brien 1989). (scielo.br)
  • Field work throughout western Puerto Rico has yielded new putative species pertaining to genera other than Lachnopus . (scielo.br)
  • Australia's fauna includes about 23,000 described species in 3,265 genera and 121 families, but the total species number is estimated to be in the range of 80,000 to 100,000. (www.csiro.au)

  • pests
  • The strawberry root weevil (Brachyrhinus ovatus (L.)) and the black vine weevil (B. sulcatus (F. )) are, as their names imply, important pests of strawberry plants and vines. (ufl.edu)
  • There are several weevil species that infest grains and are sometimes kitchen pests, including the rice weevil shown in the first photo. (hubpages.com)
  • threat
  • If the weevil finds itself under threat from an over-zealous entomologist, it gives up the illusion, tucks up its legs and rolls right off the branch, stem or leaf it was on, falling into the undergrowth and out of sight (a behaviour called thanatosis). (biodiversityinfocus.com)
  • snout
  • The species is described from a single specimen, 9.0 mm in length with a 0.6 mm snout, black in colour, with a dense covering of light, rounded scales. (com.es)
  • This species is also described from a single specimen, 7.4 mm in length with a 1.4 mm snout, black in colour with small, subcircular scales. (com.es)
  • The species is described from a single specimen, 5.0 mm in length with a 0.8 mm snout, and small oval scales. (com.es)
  • The species is described from a single specimen 3.1 mm in length with a 0.4 mm snout, brown-black on colour and with curved, narrow scales. (com.es)
  • The head is bent forward and lacks the long snout that is characteristic of true weevils. (wikipedia.org)
  • somewhat
  • They are brownish black, and, in common with most weevils, have a pronounced beak which is somewhat broadened and notched at the tip. (ufl.edu)
  • different
  • Three different species are now known to defoliate eucalyptus plantations in Australia and elsewhere in the world, but none of them are G. scutellatus . (www.csiro.au)
  • The different, partly exquisitely colored species all have a thorn-shaped extension of their head. (kit.edu)
  • known
  • Bark of ten woody species, known to be rejected as a food source by the pine weevil, Hylobius abietis, were sequentially extracted by a Soxhlet apparatus with pentane followed by methanol. (diva-portal.org)
  • They are often known as flour weevils. (hubpages.com)
  • family
  • If you don't believe me, take a look at this newly described weevil, Timorus sarcophagoides Vanin & Guerra, from Brazil, which is doing everything it can to fool you into thinking it's a flesh fly (family Sarcophagidae). (biodiversityinfocus.com)
  • In this case, the researchers would have identified the screw joint to be a so far unknown basic feature of the weevil family. (kit.edu)
  • Weevils may possibly make up one the world's largest family of animals. (asktheexterminator.com)
  • food
  • Without the predator's presence, the researchers saw that C. maculates consistently overran and killed off C. chinensis (the two weevils are competing for resources, like food and living space). (nbcnews.com)
  • host
  • The aromatic compounds benzyl alcohol and 2-phenylethanol are new non-host plant-derived feeding deterrents for the pine weevil. (diva-portal.org)
  • When the parasitoid was added, it reduced the effect of direct resource competition between the two host species by depressing host densities," the researchers write. (nbcnews.com)

  • methods
  • The field distinguishing characters, life history, and habits of each of the six species are discussed herein, and possible control measures or methods of preventing injury are suggested. (ufl.edu)
  • reach
  • The adults of both species, being wingless, migrate and reach places for opposition chiefly by crawling. (ufl.edu)
  • head
  • While they exhibit reddish head and/or pronotum with bluish coloration behind, they are nearly as strikingly close to the model as this weevil is! (biodiversityinfocus.com)
