  • It is a method of farming system which primarily aimed at cultivating the land and raising crops in such a way, as to keep the soil alive and in good health by use of organic wastes (crop, animal and farm wastes, aquatic wastes) and other biological materials along with beneficial microbes (biofertilizers) to release nutrients to crops for increased sustainable production in an eco friendly pollution free environment. (niir.org)

  • Current studies indicate that genetically modified insect-resistant Bt crops may have no adverse effects on the activity or function of predators or parasitoids used in biological control. (royalsocietypublishing.org)
  • In addition, the introduction of new crops (such as soya in central Europe), and consumer demand for 'blemish-free' produce, have all contributed to an over-reliance on chemical control, with the well-described consequences of pest resistance, uneconomic production costs, bioaccumulation through food chains, environmental pollution, loss of biodiversity and risks for human health. (royalsocietypublishing.org)
  • At the start of the twenty-first century, the opportunities and need for effective biological control are greater than ever: pest resistance continues to be a problem, pesticides are being withdrawn on environmental grounds without suitable replacements, and in some areas of the world, including Europe, there is uncertainty over the durability and public acceptance of genetically modified (GM) pest-resistant crops. (royalsocietypublishing.org)

  • While digesting the vast information produced by the project (about 250 million base pairs per species, and tens of thousands of gene variants and proteins), consortium scientists found that the majority of Nasonia 's genes are shared with humans and other animals, while one of every five genes belong to insects alone, and roughly two of every 100 genes are singularly shared between wasps and their close cousins, the honeybee. (iu.edu)
  • The scientists recognized some of these genes as similar to those found in other venom-producing insects, but about half of the 79 candidate venom genes seemed unique to the wasps. (iu.edu)
  • Nasonia wasps are used in agriculture to control insect pests. (iu.edu)
  • An understanding of the wasps' genetics could lead to tweaks in the wasps' DNA that improves their efficacy or specificity for particular pests (leaving other, beneficial insects alone). (iu.edu)
  • A small group of eusocial crabronid wasps, of the genus Microstigmus (the only eusocial wasps outside the family Vespidae), also constructs nests out of chewed plant fibers, though the nest consistency is quite different from those of true paper wasps, due to the absence of wood fibers, and the use of silk to bind the fibers. (wikipedia.org)
  • Most wasps are beneficial in their natural habitat, and are critically important in natural biocontrol. (wikipedia.org)
  • Because they are a known pollinator and feed on known garden pests, paper wasps are often considered to be beneficial by gardeners. (wikipedia.org)
  • U.S. Forest Service and Michigan State University researchers found the potentially beneficial wasps in a study plot in Livonia, Mich., and sent them to the SEL for identification. (plantmanagementnetwork.org)
  • Precisely pinpointing the wasps' identities will entail much work, as the genus Pediobius alone contains about 215 known species worldwide, 32 of which are found in North America. (plantmanagementnetwork.org)
  • But knowing their exact identities will be key if the wasps are to be used to control the emerald ash borer. (plantmanagementnetwork.org)
  • These wasps are helping to naturally control the populations of plant-feeding caterpillars, so they help to sustain the biodiversity of tropical forests. (bio-medicine.org)
