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,

Are honey bees altering wild plant–bee interactions in reconstructed native habitats? An investigation of summer season effects in row‐crop agroecosystems with prairie strips

Ecological Entomology, EarlyView.
We investigated the compatibility of beekeeping with pollinator conservation in ‘prairie strips’ a conservation practice integrating native prairie habitat into agricultural environments. At prairie strip sites with and without a honey bee apiary, we analysed plant–bee interactions and bumble bee body conditions to determine the effect of apiaries on ...

Understanding the impacts of intensity and harvest frequency on Tithonia diversifolia for use in tropical silvopastoral systems

Grassland Science, EarlyView.
Abstract Tithonia diversifolia (Hemsl.) A. Gray has significant potential as a forage source in silvopastoral systems, particularly in tropical conditions. However, its intensity and frequency management differ from those commonly applied to grasses. This study aims to evaluate T. diversifolia under two harvest intensities (30 and 40 cm stubble height)

Assessing the effects of mowing intensity on the overwintering stem‐dwelling insect community of Solidago altissima L. (Asterales: Asteraceae)

Insect Conservation and Diversity, EarlyView.
Overwintering stem‐dwelling insects exhibit a non‐random spatial structure within individual stems and within different subsections of an urban meadowscape. Low intensity mows lead to higher survival rates of overwintering stem‐dwelling insects than no mowing and high intensity mows.

Seasonality of native and non‐native flowers does not influence butterfly nectar foraging decisions in a semi‐urban meadow habitat

Insect Conservation and Diversity, EarlyView.
Non‐native nectar was well integrated into the diet of the butterfly community and relatively more available earlier in the summer. Butterflies did not use native and non‐native sources in proportion to their availability. Monarchs readily visited non‐native flowers in late summer, a critical time for energy acquisition in preparation for the monarch's
