On a survey during the period of 2006-2007 a number of tylenchids were found associated with Zea mays in Kashmir valley such as Pratylenchus sativus kaul, 1985, Aphelenchoides srinagrensis Kaul, 1985 and Tylenchorhynchus zeae Sethi and G. Swarp, 1968. These species were found to have morphometric variations probably due to habitat alteration from the originally described ones. As a part of the ...

The presence of plant-parasitic nematodes causing crop loss every year had been overlooked in the existing fruits, vegetables and flowers cultivation system Bangladesh. Therefore, study was conducted to isolate identify plantparasitic from soil infected plant-parts fruits (banana, orange), (pointed gourd, tomato brinjal) flower (gerbera) districts Jashore, Jhenaidah, Gazipur Sylhet during 2017-...

were seven replications of each of tile five treatments. T h e exper imenta l design was randomized complete blocks. In a second similar experiment , aphids, Aphis gossypii Glover, were placed on the leaves of each plant just after t ransplant ing and before the aldicarb was appl ied (4). After the aphids became established on the plant, s and were uniformly distributed, technical aldicarb was ...

A comprehensive survey of the plant parasitic nematodes associated with cowpea (Vigna unguiculata) production fields was carried out in the three primary agro-climatic zones of Burkina Faso in West Africa. Across the three zones, a total of 109 samples were collected from the farms of 32 villages to provide a representative coverage of the cowpea production areas. Samples of rhizosphere soil an...

Before studying the mechanisms by which changes in vegetation influence the nematode community following abandonment of a field, it is necessary to first assess the impact of environmental factors such as soil or climate on these organisms. The study was undertaken on sites of increasing fallow duration located in the same area in the Sudano-Sahelian zone of Senegal: a forest and 10 fallow site...

In addition to the Alu family of short interspersed repetitive DNA elements (SINEs), we have previously characterized one other repetitive DNA family (Type II) in the prosimian, Galago crassicaudatus. We present here a detailed analysis of seventeen members of a third galago SINE family designated as the Monomer family. Both the Monomer and Type II families are shown to be specific for the gala...

We have analyzed repetitive DNA sequences in a prosimian, Galago crassicaudatus, and found that there are two distinct, highly repetitive families of sequences related to the human Alu family. The Type I family is closely analogous to the human Alu Family. The Type II family of repeats, which appears to be present in higher copy number, has a right half that is almost identical to the Type I fa...

Three high-pressure liquid injection machines were used to inject isazofos into the root zone of tuff;grass plots to evaluate its potential for control of Hoplolaimus galeatus and Tylenchorhynchus dubius. A Rogers root zone injector delivering isazofos at 2.3 kg a.i./ha through 30 degrees and 60 degrees spray tips at 5,000 psi (3.45 x 10 Pascals) significantly reduced nematode populations at 32...

in order to identify the plant parasitic nematodes of tomato fields in northern khorasan province, 50 soil and root samples were collected during 2009 - 2010. nematodes were extracted by combined sieving and centrifugal-flotation method and processed to be transferred to glycerin. after preparing microscope slides, the morphological and morphometrical characters of the nematodes were studied us...
