  • EFFECTS OF VAM AND NEMATODE INTERACTION ON SOME BIOCHEMICAL PARAMETERS OF SUNFLOWER 
    N. HAJRA; K. FIROZA; F. SHAHINA (Karachi, National Nematological Research Centre (NNRC), University of Karachi,, 2009-07-21)
    An experiment was conducted to elicit biochemical substantiation for the observed differences in resistance to nematode infection in roots colonized by mycorrhiza. Sunflower shoot and roots were assayed for their biochemical ...
  • MARINE NEMATODES AT PORT BIN QASIM OF ARABIAN SEA AND THEIR ROLE IN THE ECOSYSTEM 
    K. NASIRA; F. SHAHINA; M. KAMRAN (Karachi, National Nematological Research Centre (NNRC), University of Karachi,, 2009-07-22)
    Free- living marine nematodes are the most abundant and diverse metazoan in sea and play important roles in the ecosystem. Nematodes exhibit many very different roles in aquatic ecosystem as consumers of bacteria, as grazers ...
  • DIVERSE ROLES / UTILITY OF NEMATODES IN NATURE- DO WE UNDERSTAND THEM ALL? 
    R. AZMAT; Y. AKHTER (Karachi, National Nematological Research Centre (NNRC), University of Karachi,, 2009-07-23)
    Presence of nematodes in various ecosystems and mediums such as soil, water, plants, humans, animals, fishes and other aquatic resources etc., is of great importance and concern. In every ecosystem, the nematodes like any ...
  • SUPPRESSION OF PLANT PARASITIC NEMATODES IN BERMUDA GRASS USING LIVE AND DEAD ENTOMOPATHOGENIC NEMATODE STEINERNEMA PAKISTANENSE 
    F. SHAHINA; K.A. TABASSUM (Karachi, National Nematological Research Centre (NNRC), University of Karachi,, 2009-07-24)
    Efficacy of live or dead (killed) infective stage juveniles of Steinernema pakistanense Shahina et al., (2001) against plant parasitic nematodes of Bermuda grass (Cynodon dactylon L.) was evaluated in microplot studies ...
  • MANAGEMENT OF ROOT-KNOT NEMATODE INFECTING BRINJAL BY BIOPESTICIDES, CHEMICALS, ORGANIC AMENDMENTS AND BIOCONTROL AGENT 
    M. SHAHID; A.U. REHMAN; S.H. KHAN; K. MAHMOOD; A.U. KHAN (Karachi, National Nematological Research Centre (NNRC), University of Karachi,, 2009-07-25)
    The potential of bio-pesticides, chemical pesticides, organic amendments and bio-control agent was studied in controlling the root-knot nematode Meloidogyne incognita on brinjal “cv” Dilnasheen in two greenhouse experiments. ...
  • HISTOPATHOLOGY OF GRAPEVINE ROOTS INFECTED WITH ROOTKNOT NEMATODEMELOIDOGYNE INCOGNITA 
    A. KHAN; F.M. BILQEES; N. KHATOON (Karachi, National Nematological Research Centre (NNRC), University of Karachi,, 2009-07-26)
    Histopathology of grapevine (Vitis vinifera L.) roots naturally infected with Meloidogyne incognitarevealed that the larvae entered roots by puncturing action of the stylet and reached to the stellar region by intercellular ...
  • WEEDS AS RESERVOIR OF NEMATODES 
    S.A. ANWAR; A. ZIA; N. JAVED; Q. SHAKEEL (Karachi, National Nematological Research Centre (NNRC), University of Karachi,, 2009-07-27)
    There is a hypothesis that damaging pests wide in host range continue their survival by repeated infection of host plants or alternative hosts. For example root-knot nematodes, Meloidogyne spp., are the most damaging ...
