Banker plants and landscape composition influence colonisation precocity of tomato greenhouses by mirid predators
Conservation biological control involves manipulation of the environment to enhance the effectiveness of natural enemies in controlling crop pests. In this study, we combined historical data, sticky trap sampl...

Land use alters the abundance of herbivore and predatory insects on crops: the case of alfalfa
We assess the effects of changing land use and crop management on alfalfa insect abundance by comparing it in 50 alfalfa fields when they were inserted in landscapes with different proportions of arable crops ...

Open AccessPlanting period is the main factor for controlling maize rough dwarf disease
Maize rough dwarf virus (MRDV) is one of the main yield-limiting factors of maize in the Mediterranean. However, knowledge about the interactions between the agroecosystem and the virus–vector–host relationshi...

Early planting, management of edges and non-crop habitats reduce potyvirus infection in maize
Viruses are a limiting factor in maize production areas around the world. The knowledge of the interactions between agroecosystems and the virus-vector-host system is limited, but a landscape-scale approach co...

Open AccessPre-planting inoculation for early establishment of Dicyphus bolivari and D. errans on tomatoes
Slow establishment and risks of plant damage are major constraints for the use of the predatory mirid bugs that are commercially available for release in greenhouse crops. Therefore, a new interest has turned ...

Innate and Learned Prey-Searching Behavior in a Generalist Predator
Early colonization by Zyginidia scutellaris leafhoppers might be a key factor in the attraction and settling of generalist predators, such as Orius spp., in maize fields. In this paper, we aimed to determine whet...

Mating behaviour of female Tuta absoluta (Lepidoptera: Gelechiidae): polyandry increases reproductive output
Tuta absoluta (Meyrick) is an important pest of tomato. Mass trap** of males has seldom proved an effective control measure, probably due to the pest’s reproductive biology. There are few studi...

Indirect effects of genetically modified herbicide tolerant crops on biodiversity and ecosystem services: the biological control example
Weeds can directly affect arthropods by providing favorable microclimates, food, shelter, mating sites and oviposition substrates. Indirect effects on herbivores and higher trophic level arthropods can occur i...

Response of Mythimna unipuncta Males to Components of the Sesamia nonagrioides Pheromone
Several sympatric lepidopteran species feed on maize plants, and the different components of their species-specific female sex pheromones may play a role in attracting conspecifics and/or deter heterospecific ...

Pheromone Antagonism in the European Corn Borer Moth Ostrinia nubilalis
Mixing the sex pheromones of the Mediterranean corn borer, Sesamia nonagrioides, and the European corn borer, Ostrinia nubilalis, results in significantly lower captures of O. nubilalis when compared to traps loa...

Six Years after the Commercial Introduction of Bt Maize in Spain: Field Evaluation, Impact and Future Prospects
We carried out a 6-year-field evaluation to assess potential hazards of growing Compa®, a transgenic Bt maize variety based on the transformation event CG 00256-176. Two categories of hazards were investigated...
