    Control of soldier fly with controlled-release insecticides : final report CO95011
    (BSES, 1995) Samson, PR; Harris, WJ
    The activity of controlled-release granules against soldier fly larvae was evaluated in laboratory bioassays. Five different active ingredients were tested in a range of granule sizes. The product selected as the most effective varied depending on the time which had elapsed after mixing with the soil. For most compounds, smaller granules were more active in the short term but lost activity more rapidly than the larger granules. Rates of loss of activity during incubation varied between active ingredients. Granules containing carbofuran and carbosulfan showed increased activity during the first year. The most active products in soil after 0, 1 and 2 years were phorate 2 mm granules, carbofuran 1 mm granules, carbofuran 1.5 mm granules and tefluthrin 1 mm granules, respectively.

    GrubPlan 2; developing improved risk-assessment and decision-support systems for managing greyback canegrub : SRDC final report BSS257
    (BSES, 2008) Samson, PR
    The vision of the project was to provide industry with refined greyback canegrub management systems complete with risk-assessment and decision-support models that could ultimately be deployed at a commercial consultancy level. The outputs of the project would allow proactive management of greyback canegrub by growers and their advisors.The specific objectives were to:1.Continue to develop and refine pest management packages for greyback canegrubs, incorporating regional forecasting, farm monitoring, on-farm risk assessment, decision aids and economic analysis, with groups of growers or individuals.2.Design and implement regional systems to monitor trends in greyback damage and management.3.Develop and validate models that predict the probability of greyback infestations from one year to the next.4.Determine the market acceptance and value of a greyback canegrub risk assessment and management program.

    Maximising the resistance of sugarcane to soldier fly : SRDC final report BS61S
    (BSES, 1996) Samson, PR
    Infestations of soldier fly (Inopus spp.) cause losses to sugarcane in areas from Innisfail to New South Wales. Cane losses attributable to soldier fly in Queensland in 1995 were estimated at 24 000 t, and the annual cost of soldier fly infestations to farmers and millers probably exceeds $1M. The number of farms affected by soldier fly at Mackay is increasing, and the pest has recently appeared at Ayr where it has not been recorded previously. During the late 1950s and early 1960s, losses attributable to soldier fly in Queensland were up to 80 000 t of cane per year on a much smaller assigned area. The pest was subsequently controlled by the application of dieldrin, but this chemical is no longer available and alternatives have not been found. With the loss of dieldrin, there is a high potential for a disastrous increase in losses.

    Population dynamics of Inopus rubriceps in sugarcane fields with emphasis on bionomic factors assisting pest management (Final report SRDC Project BS11S)
    (BSES, 1991) Samson, PR
    Restrictions were placed on the use of dieldrin in 1987 and its registration for use in the sugar industry lapsed in mid-1991. As no other insecticide is presently available to replace dieldrin, there is an urgent need to develop alternative control strategies. Robertson (1984). PhD thesis. UQ identified organisms predatory and parasitic on the pupal stages of soldier fly as exerting significant population control. A detailed study of the effect of biological control agents and cultural conditions may enable an effective pest management program to be developed for soldier fly.
