What Do We Really Know About Management of Insecticide Resistance?ly reported empirical and theoretical analyses have concluded that resistance develops faster as the number of generations per year increases. Analysis of data for 682 species of North American arthropod pests shows no direct relationship between generation time and resistance development. Reevaluat

How Does Spatial Structure in Populations Affect the Spread of Fungicide Resistance?Such structure influences both the initial genetic composition of a population to which fungicide is applied and the dynamics of any genetic change thereafter. First, consider application of fungicide to a small plot within a large untreated area. If plot size is small relative to gene flow distance

Analysis of Insecticide Resistance in the Whitefly, ,rough the development of insecticide resistance resulting from over-reliance on broad-spectrum insecticides. In this paper, we examine the role of resistance in contributing to current control difficulties, focussing on recent research at Rothamsted and elsewhere into the incidence and biochemical b

The Contribution of Genetic Studies to Understanding Fungicide Resistanceade has been synthesised within recent reviews by Georgopoulos (13) and Grindle (15). This paper does not attempt to provide a similarly exhaustive treatment. Rather, by restricting the presentation of findings to certain fungicides and fungi, this paper will seek to illustrate the central role that

Multiple Herbicide Resistance in Annual Ryegrass (,): A Driving Force for the Adoption of Integratedve developed resistance to one herbicide can rapidly develop resistance to new herbicides that are effective initially. Genetic diversity in ryegrass and the frequent exposure of huge numbers of plants to herbicide results in the selection of one to many different resistance genes.
