A list of the deposited type specimens with references, a detailed historical background, importance, and maintenance procedures are given for the type collection of the United States Department of Agriculture Nematode Collection (USDANC). The type specimen section is considered one of the largest and most valuable in existence. It contains 1,430 species mounted and preserved on 5,177 metal and glass slides and 404 vials. Also, a brief description of the other constituent divisions of the… Expand
List of Type Specimens Deposited Since 1998 in the United States Department of Agriculture Nematode Collection, Beltsville, Maryland.
The United States Department of Agriculture Nematode Collection (USDANC) is one of the largest and most valuable in existence and includes millions of specimens housed in over 39,800 permanent slidesExpand
E-typing for nematodes: an assessment of type specimen use by nematode taxonomists with a summary of types deposited in the Smithsonian nematode collection
TLDR
The need for E-typing of nematodes as a solution to enhance the future accessibility of type specimens is argued for and a concerted effort between museum curators, nematological journals and Nematological societies to address the problem is stressed. Expand
A key and diagnostic compendium to the species of the genus tylenchorhynchus cobb, 1913 (nematoda: belonolaimidae).
  • Z. Handoo
  • Medicine, Biology
  • Journal of nematology
  • 2000
TLDR
The diagnosis of Tylenchorhynchus is emended, and a list of all the valid species of the genus is given, and the characters most useful for separating species are the stylet length,shape of lip region, number of lip annules, shape of tail and tail terminus, and position of vulva. Expand
A Key and Compendium to Species of the Heterodera avenae Group (Nematoda: Heteroderidae).
  • Z. Handoo
  • Biology, Medicine
  • Journal of nematology
  • 2002
A key based on cyst and juvenile characters is given for identification of 12 valid Heterodera species in the H. avenae group. A compendium providing the most important diagnostic characters for useExpand
Two new species of Paurodontella Husain & Khan, 1968 (Nematoda: Sphaerulariidae) associated with wheat and a diagnostic compendium to the genus
An identification key to ten valid species of Paurodontella is given. A compendium of the most important diagnostic characters with illustrations of each species is included as a practicalExpand
A key and diagnostic compendium to the species of the genus Merlinius Siddiqi, 1970 (Nematoda: Tylenchida) with description of Merlinius khuzdarensis n. sp. associated with date palm
TLDR
The present authors agree with both Siddiqi (1970) and Tarjan (1973) that their action makes it easier to handle this complex and large group of nematodes and Merlinius, therefore, justifiable. Expand
Morphological and molecular characterisation of Punctodera mulveyi n. sp. (Nematoda: Punctoderidae) from a golf course green in Oregon, USA, with a key to species of Punctodera
TLDR
Morphologically the new species resembles all known species of Punctodera, but differs from the other species either by the J2 body and stylet length, shape of head, tail and tail terminus, female and male stylet or spicule length, and in having distinctive vulval and anal circumfenestral patterns in the cysts.

Changes in antioxidative enzymes in resistant and susceptible genotypes of tomato Infected with root-knot nematode (Meloidogyne incognita)
TLDR
Changes in activities of antioxidative enzymes after nematode inoculation were investigated in four varieties of tomatoes, finding that the activity of antioxidant enzymes were more after inoculation in the resistant genotypes as compared to that of susceptible genotypes. Expand
