  • Reid, Peter (1984-12-05)
    At Narrabri we are continuing our breeding program to develop locally adapted early maturing varieties. At present there are no early varieties available commercially in Australia hut we feel that they could play an important role
  • Wilson, A.G.L. (1984-12-05)
    A contribution was made to the last ACGRA conference on "The duration.of insecticidal activity against Heliothis larvae on cotton". This paper.is primarily an update of the previous contribution and the more detailed.results ...
  • Wilson, A.G.L. (1984-12-05)
    To optimize catches of Heliothis punctigera and H. armigera pheromone blends, dispenser and trap design have been evaluated and modified over a.7 year period. A laminated plastic lure loaded with appropriate pheromone ...
  • Allaway, R.A. (1984-12-05)
    In agriculture we often hear reports of new wonder varieties that are about.to revolutionise agriculture, yet when these varieties are released, if.indeed they are released, they seem to fall far short of the publicity ...
  • Daly, Joanne (1984-12-05)
    The term 'genetics' encompasses a group of disciplines which study aspects of evolution. the first of these, molecular genetics, examines DNA, the raw material of evolution, and its organisation into genes. Genes code for ...
  • Forrester, N.W.; Cahill, M. (1984-12-05)
    In response to the development of resistance to pyrethroids by Heliothis armigera in 1983, an Insecticide management strategy was devised.in an attempt to prolong the field effectiveness of this and indeed, the other ...
  • Luckett, D.J. (1984-12-05)
    The high quality cotton Namcala and its predecessor Hopicala have traditionally been grown on small percentages of the Australian cotton acreage (Mainly in NSW) as an alternative to the high yielding varieties such as ...
  • Ashburner, , N.A.; Brook, K.D.; DaRoza, G.D. (1984-12-05)
    One of the notable features of the SIRATAC pest management system is that its use followed extremely quickly on its initial formulation. Most of SIRATAC's development therefor, has occurred in the commercial environment. ...
  • Fitt, Gary P. (1984-12-05)
    With the appearance of pvrethroid resistance in Heliothis armigera during the 1992/3 cropping season a strategy aimed at limiting the development of widespread resistance was rapidly implemented .H. armigera had previously ...
  • Brook, , K.D.; Hearn., A.B. (1984-12-05)
    This paper reports the initial results from testing different versions of the SIRATAC pest management system in the Namoi Valley for two seasons the experiments were designed to investigate the ability of the program to ...
  • Lawrence, Peter; Berthelsen, John; Hare., Jenelle (1984-12-05)
    Different cultivars are now becoming commercially available including Australian bred cultivars, and cotton growers now have a choice of which cultivar to plant. Hence, the question is, do the different cotton growing ...
  • Gunning, R.V. (1984-12-05)
    The cotton bollworm, Heliothis armiger is a very important cotton pest in Australia. It has a long history of insecticide resistance in Australia, to DDT in the early 1970's and to the pyrethroids in 1983,.In 1976, ...
  • Thomson, N.J. (1984-12-05)
    In 1981 we released SICOT 3 to the industry. This variety is distinguished by glabrous (ultra-smooth) leaves and stems, and frego bracts (these morphological characteristics and their effects on pests are described in ...
  • Daly, Joanne; Drake, Alistair; Farrow, Roger (1984-12-05)
    A knowledge of dispersal is essential to an understanding of population control and to the management of insecticide resistance. The Division of Entomology, CSIRO, is undertaking ecological studies and radar observations ...

  • Thomson, N.J.; Reid, P.; Fitt, G. (1984-12-05)
    Over the last quarter of a century, as problems in relying completely on pesticides for control of insects have become apparent, there has been renewed interest in the possibility of breeding cottons less susceptible to ...
  • Unknown author (1984-12-05)
  • Hamilton, David (1984-12-05)
    At Emerald, in the 1982/83 season, significant levels of field resistance in Heliothis armiger to synthetic pyrethroid insecticides were detected. In the field, many of the later maturing crops were severely damaged by ...
  • Hughes, Dennis G. (1984-12-05)
    This subject is very relevant to the Australian Cotton Growing Industry as the most common complaint against our major seed variety, DPL 61, is that this growth has a lower breaking strength when it is produced in Australia ...
