Herbivore prevalence poorly predicts yield in diverse cropping systems
Journal of Applied Ecology, EarlyView.Our study shows that the design and characteristics of cropping systems should be considered when assessing insect herbivory effects on crop yield. As herbivorous insects have a smaller impact on yield in diverse cropping systems, crop diversification may synergize biodiversity conservation and food production. Abstract Industrialized agriculture needs

Journal of Ecology, EarlyView.These findings indicate that symbiotic fungal partnerships and silicon provision may benefit plants but could weaken anti‐herbivore defences when combined. Revealing the complex interactions among diverse fungal symbionts and showcasing their effects on different anti‐herbivore defences (chemical and physical) and herbivore performance for the first ...

European Journal of Environmental Sciences, 2011 Many studies indicate that there is a density of aphids below which ladybirds are unlikely to lay eggs. This is adaptive as theory indicates that a certain minimum population density of aphids is required if hatchling larvae are to survive. The responses

Facultative bacterial endosymbionts benefit pea aphids Acyrthosiphon pisum under heat stress
, 2002 1. Natural populations of pea aphids in California contain at least two facultative bacterial secondary symbionts (pea aphid secondary symbiont, PASS, or pea aphid rickettsia, PAR) in a range of frequencies throughout the state.

Fast‐growing annual plants drive disease spillover in multi‐host communities
Journal of Ecology, EarlyView.Our modelling study predicts that slower‐growing hosts will bear the greater impact of pathogen spillover in the form of reduced end‐of‐season biomass (panel A). Faster‐growing hosts are predicted to be high impact reservoirs for spillover and could amplify disease in multi‐host communities (panel B).

Assessing biological models using topological data analysis [PDF]
arXiv, 2018 We use topological data analysis as a tool to analyze the fit of mathematical models to experimental data. This study is built on data obtained from motion tracking groups of aphids in [Nilsen et al., PLOS One, 2013] and two random walk models that were proposed to describe the data.

Insect Science, EarlyView.We report the first high‐quality chromosome‐level genome assembly for the aphid Uroleucon formosanum, a serious pest that infests lettuce in eastern Asia. A combination of comparative genomic analyses and RNA‐seq transcriptome profiling suggests that U. formosanum employs integrative mechanisms to cope with host plant‐derived sesquiterpene lactone (STL)
