Aphids and their natural enemies are differently affected by habitat features at local and landscape scales (2012, background): “Furthermore, the positive effect of a high PAL on coccinellid community was somewhat expected given that simplified landscapes with a high proportion of annually-tilled land have been shown to benefit aphidophagous insects such as C. semptempunctata (Grez et al., 2008; Rand and Tscharntke, 2007).”
Spillover of functionally important organisms between managed and natural habitats (2012, background): “Another study found that wheat-dominated landscapes appear to augment generalist predators (ladybird beetles and spiders) of nettle aphids resulting in dramatically higher natural enemy–prey ratios and reduced aphid density in adjacent nettle patches (Rand and Tscharntke, 2007).”
Landscape effects on the complex of Bactrocera oleae parasitoids and implications for conservation biological control (2009, background): “…Weibull et al. 2003), minor crop pests (Östman et al. 2001; Roschewitz et al. 2005) or model systems based on non-crop plants (Elziga et al. 2007; Rand and Tscharntke 2007), therefore contributing very little concrete knowledge to the biological control of key pests with widely recognized…”
How climate change affects the seasonal ecology of insect parasitoids (2020, background): “…for traits like thermal tolerance or degree of host specialisation should adapt better to climate changes than specialist species; thus the latter should be under stronger selective pressure for phenological adjustments (Rand & Tscharntke, 2007; Tylianakis et al., 2008; Vázquez et al., 2015).”
Global change and species interactions in terrestrial ecosystems. (2008, background): “Loss of consumers at higher trophic levels could potentially benefit herbivores, but this effect is highly dependent on the mechanism of operation and specialization of the predator or parasitoid species involved (specialists may be more severely affected than generalists; Rand & Tscharntke 2007).”
Landscape moderation of biodiversity patterns and processes ‐ eight hypotheses (2012, background): “This gives rise to what might be termed a specialist consumer hypothesis of landscape effects (Kruess & Tscharntke, 1994, 2000; Tscharntke & Kruess, 1999; Rand & Tscharntke, 2007) that specialised higher trophic-level species are more affected by landscape change than are their prey species.”
