The influence of age on reproductive performance of the predatory ladybird beetle, Propylea dissecta

open access: yesJournal of Insect Science, 2004
The influence of age on reproductive performance of an aphidophagous ladybird beetle, Propylea dissecta was examined using male and female beetles of varying ages (1-30 days) after a single mating stimulus.

Fast‐growing annual plants drive disease spillover in multi‐host communities

open access: yesJournal 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).

An integrative strategy used by the aphid Uroleucon formosanum to counter host sesquiterpene lactone defense: Insights from combined genomic and transcriptomic analysis

open access: yesInsect 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)

Differences in within‐plant oviposition preferences and immature survival between Orius predators and the importance of spatial availability of prey

open access: yesInsect Science, EarlyView.
Orius predators oviposit endophytically, and plant characteristics play an important role in their oviposition choices. In this study, we show that oviposition preferences differ between species, and that these differences may correlate with juvenile performance.

Sub-lethal effect of combination of Metarhizium anisopliae and imidacloprid on life table of Myzus persicae (Hem.: Aphididae)

open access: yesJournal of Crop Protection, 2015
The sub-lethal effect of Metarhizium anisopliae and imidacloprid as well as combination of the two control agents was examined on life table parameters of Myzus persicae on different cultivars of canola under laboratory condition at 25 ± 1 ºC, 85% RH and

Exploring marking methods for the predatory hoverfly Sphaerophoria rueppellii (Diptera: Syrphidae)

open access: yesInsect Science, EarlyView.
As important pollinators and predators of aphids, hoverflies play an important role in ecosystems. This study focuses on identifying the best marking technique for the model species Sphaerophoria rueppellii that can be used to track hoverfly feeding and oviposition sites, evaluating three methods: rubidium (RbCl), fluorescein, and fluorescent dusts ...

AgoArmet and AgoC002: key effector proteins in cotton aphids host adaptation

open access: yesFrontiers in Plant Science
Aphids are insects that feed on phloem and introduce effector proteins into plant cells through saliva. These effector proteins are key in regulating host plant defense and enhancing aphid host adaptation.
