Pests and Agricultural Commodity Losses: Evaluating Alternative Approaches to Damage Function Estimation [PDF]

Estimating the economic impact of a pest requires linking biological and economic systems via a damage function. The most common damage function approach links exogenous pest populations to cumulative commodity yield losses at harvest.

Exploring climate-driven phenological mismatches in pears, pests and natural enemies: a multi-model approach

Journal of Pest Science
Abstract Pear psyllid (Cacopsylla pyri) is the dominant pest of UK pear orchards, with an estimated cost of £5 million per annum. Insecticide withdrawal and increased pesticide resistance of C. pyri have led many growers to depend more on natural enemies for pest management, including earwigs. However, there is concern how phenological events

APPLICATION OF THE ECONOMIC THRESHOLD FOR INTERSEASONAL PEST CONTROL [PDF]

We show how an interseasonal pest control problem can be simplified to enable an intraseasonal model to be empirically applied, extending the range of application of the intraseasonal model. Three alternative economic thresholds are compared. The optimal

Plant Domestication Affects the Oviposition Behavior and Performance of Ganaspis kimorum, a Parasitoid of Drosophila suzukii

Entomologia Experimentalis et Applicata, EarlyView.
In this study, we investigated the effects of blueberry domestication on the oviposition behavior and performance of Ganaspis kimorum, a parasitoid of Drosophila suzukii. Domestication of blueberries reduced the oviposition‐searching behavior of the parasitoid but enhanced parasitoid performance, including offspring performance. Additionally, blueberry

The Parasitoid Wasp Glyptapanteles porthetriae Induces a Photoperiod‐Dependent Diapause‐Like State in Its Potential Overwintering Host Lasiocampa quercus

Entomologia Experimentalis et Applicata, EarlyView.
We evaluated Lasiocampa quercus as an overwintering host for the koinobiont larval endoparasitoid Glyptapanteles porthetriae by exposing parasitized larvae to different environmental conditions and comparing parasitoid development with that in the primary host Lymantria dispar.
