Ethnobotanical survey of pesticidal plants used in South Uganda : case study of Masaka district [PDF]

, 2011
Use of synthetic pesticides in developing countries is not only limited by their being expensive but also the small (uneconomic) fields whose limited production costs cannot offset costs of agricultural implements like agro-chemicals. Subsistence farmers,

Balancing tracks and trees: Assessing railroad impact on Brazilian biodiversity

PLANTS, PEOPLE, PLANET, EarlyView.
The Brazilian West–East Integration Railway (FIOL) aims to boost the national economy by improving commodity transport; however, it crosses three of Brazil's most biodiverse and fragile regions: the Caatinga, Cerrado and Atlantic Forest. Using digitised plant records and land‐use analyses, our study reveals significant vegetation loss within the ...

Short‐term responses in weed spatial patterns during early adoption of conservation agriculture practices

Pest Management Science, EarlyView.
Weed spatial patterns and temporal stability were shaped by species life forms and the cropping systems implemented in the plots. Weed aggregation was more pronounced in conservation agriculture and among perennials. Patch stability was primarily governed by species life form and was stronger among perennials. Abstract BACKGROUND The aggregated spatial

Towards an attract‐and‐reward strategy: evaluating nectar resources and HIPVs under laboratory conditions to enhance Aphelinus mali parasitism activity, a key parasitoid of Eriosoma lanigerum

Pest Management Science, EarlyView.
Euphorbia segetalis is a promising attractant insectary plant for Aphelinus mali. Meanwhile, Vicia faba and Vicia sativa are a promising nectar resource to sustain the parasitoid in early spring when the population of Eriosoma lanigerum is low, and honeydew is scarce.

Potential of the Predatory Mites Gamasellodes lavafesii (Mesostigmata: Ascidae) and Cosmolaelaps mediocuspis (Mesostigmata: Laelapidae) on Different Soil Pests/Parasites and Alternative Prey for Large‐Scale Rearing

Journal of Applied Entomology, EarlyView.
ABSTRACT Many species of Mesostigmata soil mites have potential as biological control agents of pests/parasites. This study evaluated the predation potential of two of these species, Gamasellodes lavafesii (Ascidae) and Cosmolaelaps mediocuspis (Laelapidae).
