  • Economic Insects and Biological Control in the British Solomon Islands
    Bulletin of Entomological Research, 2020
    Co-Authors: R. J. A. W. Lever
    Abstract:

    A previous paper in this Bulletin dealt with the Economic Entomology of the British Solomon Islands Protectorate up to the year 1932. The present article concerns research conducted after that date with special reference to the biological control of two insect pests.

  • Status of Economic Entomology in the British Solomon Islands
    Bulletin of Entomological Research, 2020
    Co-Authors: R. J. A. W. Lever
    Abstract:

    The Solomon Islands lie to the east of New Guinea and consist of an archipelago a thousand miles in length and about half this distance in breadth. They are divided politically into the Northern Solomons (formerly German but now administered under Mandate by Australia), and the British Solomon Islands Protectorate. This latter lies roughly between five and twelve degrees south of the equator and is believed to have been united both to New Guinea and Australia from at least the Triassic to the early Tertiary. As there is now a deep sea between the archipelago and the two land-masses, the former falls into the ancient section of the continental islands of Wallace.The rainfall averages 150 inches, the maximum shade temperature has a mean of 90°F., and the relative atmospheric humidity averages 92 per cent.The Group consists of six large islands ranging from 60 to 120 miles in length and many smaller ones, including the isolated Santa Cruz group to the east. The main islands are composed of both coralline and volcanic (chiefly diorite) rocks and hence exhibit a wide range of soil-types from coralline sands and red clay to alluvium. Evidence of former extensive elevation is provided in raised coral-beaches. The islands are generally covered with jungle and densely wooded to their summits which rise in places to over 8,000 feet. An exception to this is the central and western portions of the northern coast of Guadalcanal, which consist of grass plains and undulating downland.

  • New Leadership in the Canadian Division of Entomology
    The Canadian Entomologist, 2020
    Co-Authors: W. R. Thompson
    Abstract:

    The Division of Entomology in the Canadian Department of Agriculture is now one of the largest entomological services in the entire world, second only to the Bureau of Entomology and Plant Quarantine of the United States Department of Agriculture. Its staff now comprises over 300 professional officers and its annual budget is in the neighborhood of $3,000,000. Entomology, in such settings is, in the main, Economic Entomology: ancillary to agriculture. Pursuing this idea to what seems its logical conclusion, the authorities in some parts of the world have attempted, sometimes with success, to break up the entomological body into a collection of subordinate units, each working under more or less specialized agricuImra1 direction; so that the entomologist becomes a member of an agricultural team, concentrating on some special objective. Such arrangements are fairly common in the old world. Outstanding examples in Great Britain are the Horticultural Research Station at East Malling and the Agricultural and Horticultural Research Station at Long Ashton.

  • CAN Economic Entomology BE AN EXACT SCIENCE
    Canadian Entomologist, 2012
    Co-Authors: W. R. Thompson
    Abstract:

    Whether Economic Entomology can be an exact science is, I think, a question in which we should all be interested. I propose therefore to examine it with the care that it deserves though I will try to make the discussion as brief as possible.Broadlly speaking, the sciences can be divided into two classes: the speculative sciences, whose object is simply the discovery of truth: new facts or new laws; and the practical sciences, whose objest is the production of facts: causing something new to happen.

  • The Philosophical Foundations of Systematica
    Canadian Entomologist, 2012
    Co-Authors: W. R. Thompson
    Abstract:

    At the time when the Entomological Society of Canada was founded, 88 years ago, the science of Entomology was almost synonymous with systematics. I say almost synonymous, because important advances in the study of insect development and behaviour had already occurred and even Economic Entomology, which now absorbs nine-tenths of our professional effort, was already showing signs of growth. Nevertheless, the great names in Entomology were still those of the systematists. The work of description and classification was still the most absorbing interest in the entomological field.

  • finding the Economics in Economic Entomology
    Journal of Economic Entomology, 2009
    Co-Authors: David W. Onstad, Lisa M. Knolhoff
    Abstract:

    ABSTRACT To recommend new pest management tactics and strategies to farmers and policy makers, Economic entomologists must evaluate the Economics of biologically reasonable approaches. We collected data to determine how frequently these Economic evaluations occur. We discovered from our survey of entomological journals representing the discipline of Economic Entomology that <1% of research papers published since 1972 include Economic evaluations of pest management tactics. At least 85% of these analyses were performed by entomologists and not economists. Much of the research on Economic evaluations is performed without special funds granted by agencies separate from the authors' institutions. In the United States, USDA competitive grants supported 20% of the Economic evaluations published since 2000. However, only ≈12% of the projects funded since 2000 by three sections of the USDA (Crops at Risk, Risk Avoidance and Mitigation Program, and Pest Management Alternatives Program) resulted in publications con...

  • Management of Insecticide Resistance in Insect
    2016
    Co-Authors: S. Routray
    Abstract:

    Resistance has been defined as a developed ability in a strain to tolerate doses of toxicants which would prove lethal to the majority of individuals in normal population of the same species (Anonymous,1957), World Health Organization (WHO), Expert Committee on Insecticides, (1957). Insecticides resistance management (IRM) strategies are becoming more important in agricultural production system. Pest resistance to a insecticide can be managed by reducing selection pressure by the insecticide on the pest population.Preventing and managing resistance to insecticides is an important stewardship practice that ensure insect control products will remain effective long term.In other words, the situation when all the pest except the most resistant ones are killed by a given chemical should be avoided.Resistance to insecticides was first documented in 1914 by A. L. Melander in the Journal of Economic Entomology.
