Identification of Novel Pesticides for Use against Glasshouse Invertebrate Pests in UK Tomatoes and Peppers
TLDR
The results suggest that certain biopesticide products, particularly botanicals, provide good levels of pest control, with the same being true of experimental conventional chemical pesticides not yet recommended for use against these pests on these crops.
Prey-Mediated Effects of Drought on the Consumption Rates of Coccinellid Predators of Elatobium abietinum
TLDR
The findings of this study suggest that, under drought conditions, a prey-mediated effect on predator consumption, and, therefore, biocontrol efficacy, is likely, with drought intensity and frequency playing an important role in determining the nature of the response.
Predator mortality depends on whether its prey feeds on organic or conventionally fertilised plants
TLDR
This work investigated whether fertiliser type and concentration alter the mortality of coccinellids feeding on two aphid species from Brassica plants growing in fertilisers typical of organic and conventional farming systems, due to differences in concentrations of defensive glucosinolate compounds cascading up the food chain.
Frequency and intensity of drought stress alters the population size and dynamics of Elatobium abietinum on Sitka spruce
TLDR
Aphid infestation significantly increased percentage needle loss under all drought treatments, although no differences were observed between drought levels, and the implications for damage to host Sitka spruce are of relevance to forest management strategies, as an increase in drought events are predicted in the UK.
Reproduction of an arboreal aphid pest, Elatobium abietinum, is altered under drought stress
TLDR
Drought stress has the potential to alter E. abietinum population densities, structure and phenology in Sitka spruce plantations, with implications for forest management, damage levels and natural control of the aphid under future altered climate.
Season and drought stress mediate growth and weight of the green spruce aphid on Sitka spruce
TLDR
Growth rate, adult weight and nymph weight were consistently increased under low amplitude intermittent drought stress, suggesting improved host nutritional quality through the year and increased fecundity, and continuous severe stress improved host quality during the autumn.
Drought intensity and frequency have contrasting effects on development time and survival of the green spruce aphid
TLDR
It is suggested that, under severe water deficit, populations of E. abietinum may be reduced as a result of a reduced period of time available for reproduction and, consequently, damage levels and growth reductions of host Sitka spruce under altered climatic conditions.
Reviewers for Journal of Economic Entomology: (September 2014-September 2015).
TLDR
This book aims to provide a history of Uzbekistan from 1989 to 2002, a period chosen in order to explore its roots as well as specific cases up to and including the year in which the country gained independence.
