Managment of Crops to Prevent Pest Outbreaks Organic Eprints
Daniel, Claudia; Barloggio, Guendalina; Stoeckli, Sibylle; Luka, Henryk; Niggli, Urs.
Organic farmers face the same potentially severe pest problems as their colleagues in integrated pest management (IPM) and conventional farming systems. However, approaches to manage the pest insects are different because the aim of organic farming is a holistic system perspective rather than simple reductionist control approaches. Organic cropping systems are designed to prevent damaging levels of pests, thus minimizing the need for direct and curative pest control (Peacock and Norton, 1990). Within the following chapter, we will briefly explain the standards for organic farming, which also set the framework for

Technique of pneumatic pest control – analyses and a new device Organic Eprints
Schäfer, Winfried.
Pest control in organic production of berries, potatoes and vegetables usually employs spreading technique of registered phytopharmaceutical agents. This technique may be supported or even replaced by pneumatic pest control. Pneumatic pest control means suction of pest using a vacuum device similar to a home vacuum cleaner. Up to now there is no evaluation of pneumatic pest control available from an agricultural engineering point of view. This paper concerns the following questions: Which techniques of pneumatic pest control are available and how may these...

EVALUATION OF VARIOUS PEST-MANAGEMENT CHARACTERISTICS AgEcon
Smith, G. Scott; Wetzstein, Michael E.; Douce, G. Keith.
Considering pest management in terms of a set of technology characteristics allows an investigation of various pest-management characteristics and how they relate to a total pest-management package. Employing restricted and unrestricted least squares in this investigation indicates the unique impact individual pest-management characteristics exert on net returns. A Stein-rule estimator is also employed in assessing this impact.

Pest and Disease Control in Grass and Forage Crops Organic Eprints
Buckingham, Sue; McCalman, Heather; Powell, Huw.
Pest and diseases can have a significant effect on the establishment, yield and longevity of grass and forage crops. This tool is an atlas for the identification of the main pests regarding grass and forage crops. It has been written for Wales climates and it is not specific for organic farming. Nonetheless, the information contained, can be used by farmers, conventional or organic, skilled or newcomers, all over Europe. Besides pest descriptions, with pictures that facilitate the task of identification, it provides useful hints on preventive, non-chemical, practices to reduce pest incidence.

Pest Resistance Regulation and Pest Mobility AgEcon
Ambec, Stefan; Desquilbet, Marion.
We use a spatially-explicit analytical framework to compare mandatory refuges and a tax on the resistant variety as regulation instruments for pest resistance management. Because the extraction of the common-pool pest susceptibility resource depends on the spatial pattern of pest dispersal, we find that the usual preference for market-based environmental instruments does not necessarily apply to pest resistance management. Mandatory refuges are preferred to a tax on the resistant variety for some assumption sets on heterogeneity between farms and pest dispersal distances.

Ecological engineering: a new direction for agricultural pest management AgEcon
Gurr, Geoff M.; Wratten, Steve D.; Altieri, Miguel A..
Ecological engineering has recently emerged as a paradigm for considering pest management approaches that are based on cultural practices and informed by ecological knowledge rather than on high technology approaches such as synthetic pesticides and genetically engineered crops (Gurr et al. 2004a). This article provides a brief summary of ecological engineering for arthropod pest management and contrasts it with its controversial cousin, genetic engineering. The development of ecological engineering is explored, ranging from a simple first approximation that diversity is beneficial, to contemporary understanding that diversity can have adverse effects on

Pest Control in the Presence of Pest Suppression by Natural Enemies AgEcon
Zhang, Wei; Swinton, Scott M..
The control of pests by their natural enemies represents an important ecosystem service that maintains the stability of agroecosystems and has the potential to mitigate pest control costs both to private producers and to society. Extending the “"economic threshold”" concept, this paper proposes an "“ecological economic threshold”" for pesticide use that takes into account the implicit cost of injury to natural enemies. By explicitly accounting for natural pest suppression, the ecological economic threshold can potentially make pest management more cost-effective while reducing dependence on toxic insecticides. The threshold is illustrated via an...

Local vs. Landscape Effects of Woody Field Borders as Barriers to Crop Pest Movement Ecology and Society
Bhar, Rod; Ottawa-Carleton Institute of Biology; rbhar@ccs.carleton.ca; Fahrig, Lenore; Carleton University; lfahrig@ccs.carleton.ca.
Maintenance of woody borders surrounding crop fields is desirable for biodiversity conservation. However, for crop pest management, the desirability of woody borders depends on the trade-off between their effects at the local field scale and the landscape scale. At the local scale, woody borders can reduce pest populations by increasing predation rates, but they can also increase pest populations by providing complementary habitats and reducing movement rate of pests out of crop fields. At the regional scale, woody borders can reduce pest populations by reducing colonization of newly planted crop fields. Our objective was...

Pest Management in Organic Field vegetables in Temperate Areas Organic Eprints
Daniel, Claudia; Collier, Rosemary; Niggli, Urs; Koller, Martin.
Preventative measures and the creation of resilient growing systems are key parts of pest management practice in organic field vegetable production (see also chapter 1). Soil improvement, crop rotation, site selection, habitat management, variety choice, timing of planting and plant spacing are all considered before planting in order to avoid the most detrimental pest problems. Due to the huge variety of vegetable crops and their associated pest insects, specific tailored approaches are necessary. The effects of cultural practices to reduce pest outbreaks, such as weed control, appropriate irrigation, suitable...

ADDITIVE VERSUS PROPORTIONAL PEST DAMAGE FUNCTIONS: WHY ECOLOGY MATTERS AgEcon
Mitchell, Paul D..
Economic analyses of pests typically assume damage is either additively separable from pest free yield or proportional to it. This paper describes the ecological assumptions required for additive and proportional damage functions to demonstrate that both specifications are reasonable. Ecological research supports a proportional damage function for competitive pests such as weeds, while for insect pests the appropriate damage function depends on the level of pest free yield. Theoretical analysis identifies differences between additive and proportional damage functions in terms of the impact of pest control on output variance and the concavity of output...

Weather Forecast Based Conditional Pest Management: A Stochastic Optimal Control Investigation AgEcon
Lu, Liang; Elbakidze, Levan.
In this paper, we examine conditional, forecast-based dynamic pest management in agricultural crop production given stochastic pest infestations and stochastic climate dynamics throughout the growing season. Using stochastic optimal control we show that correlation between forecast error for climate prediction and forecast error for pest outbreaks can be used to improve pesticide application efficiency. In the general setting, we apply modified Hamiltonian approach to discuss the steady state equilibrium. Given specific functional forms, a closed form solution can be found for the stochastic optimal control problem. Moreover, we find conditions for model...

Multiple Adoption of Pest Management Technologies in UK cereal Farming AgEcon
Fraser, Iain; Sharma, Abhijit; Bailey, Alastair.
In this paper we consider the adoption of pest management technologies by farmers in UK cereal crop systems. While for the majority of UK farmers chemical control of pest outbreaks remains important, there are a range of non-chemical approaches and management practices that can be used to control pest populations. However, few of these alternatives produce levels of control that compare with chemical use in isolation. In this paper we consider the determinants of adoption of different combinations of individual pest management technologies. Based on survey data we first construct sets of

Community Action and Pest Control AgEcon
Davis, Rex; Harrison, Stephen R..
Several authors have recognised pests as a negative common property resource. As a common property issue, there are often benefits to be gained in regional coordination of pest control activities. Entomologists have also recognised the potential benefits from regional coordination programs and have encouraged areawide Integrated Pest Management (IPM) strategies. However, despite the acknowledgment of differences between individual and regional economic thresholds, studies have not been conducted into the conditions that ensure or prevent collective action in pest control. This is surprising given the vast amount of literature on collective action theory...

Entomopathogenic fungi infecting non-pest insects: Implications for ecosystem services and relevance of behavioural ecology Organic Eprints
Meyling, Nicolai V.; Eilenberg, Jørgen.
Entomopathogenic fungi infect a wide array of insects from most orders and they are among the natural enemies that contribute to the regulation of insect populations. However, only a limited number of studies have focused on the impact of fungal pathogens on populations of non-pest insects. Effects of entomopathogenic fungi on non-pest host populations should receive more attention based on the increasing interest in conservation biological control. In this strategy, founded on competition theory, non-pest host populations adjacent to cropping systems will in principle affect pest populations through shared natural...

Alternative Specifications and Extensions of the Economic Threshold Concept and the Control of Livestock Pests AgEcon
Davis, Rex; Tisdell, Clement A..
Outlines economic threshold models developed by various authors as an aid to decision-making about pest management. Particular attention is given to the models proposed by Stern et al. (1959) and by Headley (1972) and the major differences in their concepts of the economic threshold. Limitations and scope for applying these models is discussed as well as differences in the extent of their applications are reviewed. After considering general issues in this respect, particular matters are given attention such as difficulties raised by complexities in the nature of yield loss function due to uncertainty in pest densities, the presence of multiple-pests, and the occurrence of pesticide...

The use of an integrated model of pest spread and commodity markets to estimate the cost of a pest outbreak AgEcon
Hafi, Ahmed.
There are significant benefits in integrating a biological spread model into economic assessment of the cost of pest incursions (such as varroa mite or Mexican feather grass) on agricultural industries. To illustrate the potential usefulness of an integrated approach, a generic bioeconomic model is developed by linking a simple stochastic pest spread module, built around a set of logistic spread equations, and a partial equilibrium module of the market for an affected agricultural industry. The pest spread module estimates the damage over time, while the partial equilibrium module estimates the resultant effect of a reduction in supply on the commodity...

BIOTECHNOLOGY AND PEST RESISTANCE: AN ECONOMIC ASSESSMENT OF REFUGES AgEcon
Hurley, Terrance M.; Babcock, Bruce A.; Hellmich, Richard L..
Transgenic crops offer farmers a new and effective pest control option. However, the wide spread adoption of these crops could lead to a resistant pest population. This paper demonstrates how a pest refuge can be used to maximise the value of farm income in a dynamic model with genetic foundations.
