Ecological engineering in cauliflower for aphid management
The Indian Journal of Agricultural Sciences, 2020 Because of high-value, the crops like Brassica have very low pest-damage thresholds, natural enemies alone are unlikely to replace use of high cost insecticides.

Farming in the shadows of Rome: A multi‐proxy palaeoenvironmental record from Loch Clunie—Perthshire
Journal of Quaternary Science, EarlyView.ABSTRACT Roman impacts on local society is a subject of international significance. Loch Clunie, Perthshire, lies only 5.4 km from Inchtuthil, the only Roman legionary fortress in Scotland, and contains two crannogs and a probable lakeside hillfort. Despite this proximity and the likelihood of local–Roman interaction, these sites remain unexcavated ...

Keanekaragaman laba-laba dan potensinya sebagai musuh alami hama tanaman jambu mete
Jurnal Entomologi Indonesia, 2015 Sanurus sp., Acrocercops sp. and Helopeltis sp. are important pests of cashews in Nusa Tenggara Barat. Pesticide usage to control these pests has so far not been successful, and thus the usage of natural enemy as an alternative control methods should be ...

Turning the Tables: Leveraging Purpose as a Strategic Advantage for SMEs
Strategic Change, EarlyView.ABSTRACT When executed well, purpose can become a transformative force, turning a business into a breakout success. Despite the wave of purpose‐driven businesses in recent years, the concept of purpose remains underdeveloped. Purpose is a core component of business models but is difficult to retrofit into large corporations, which makes it especially ...

The effect of multiple natural enemies on a shared herbivore prey
Ecology and Evolution, 2019 Natural enemy diversity is thought to be important for effective suppression of herbivores in production systems. Studies investigating the importance of the diversity and composition of the natural enemy complex often use within‐year empirical studies ...

T(w)o Patch or Not T(w)o Patch: A Novel Biocontrol Model
Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT A number of top‐down biocontrol models have been proposed where the introduced predators' efficacy is enhanced via the provision of additional food (AF). However, if the predator has a pest‐dependent monotone functional response, pest extinction is unattainable. In the current manuscript, we propose a model where a predator with pest‐dependent

Natural enemy diversity reduces temporal variability in wasp but not bee parasitism [PDF]
, 2009 Biodiversity may enhance and stabilise ecosystem functioning, but little evidence exists for diversity–function relationships involving multitrophic interactions in real landscapes.

Sexual reproduction in invasive Japanese knotweed (Reynoutria japonica) in south Sweden
Nordic Journal of Botany, EarlyView.To understand the potential for northward expansion of knotweeds into currently uninvaded regions, it is crucial to assess the potential for sexual reproduction alongside the ongoing vegetative spread. For that reason, we tested viability in Reynoutria japonica seeds in south Sweden, a region where viable seeds had not been previously reported ...

Spatial distribution of the natural enemies of the cotton aphid, and the comparison of its estimating procedures in cotton fields of Gorgan, Iran [PDF]
نامه انجمن حشرهشناسی ایران, 2008 Spatial distribution of different natural enemies of the cotton aphid, Aphis gossypii Glover, was determined by fitting data to either Poisson (random) or negative binomial (aggregated) distributions and calculating dispersion indices, during 2002 and ...
