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

Reduced fertilization regimes could boost biocontrol service without reducing crop yield

open access: yesInsect Science, EarlyView.
Fertilization level influences pest control effectiveness in tomato crops. High fertilization increases plant growth and aphid density but reduces the performance of the parasitoid Aphidius ervi. In contrast, the predator Adalia bipunctata maintains consistent aphid suppression regardless of fertilization regime.

The effect of sewage sludge application to an agricultural soil on the fecundity of the Rose Grain aphid (Metopolophium dirhodum). [PDF]

open access: yes
A pot trial was used to assess the effect of amending soil with sewage sludge on the number of offspring produced by individual Rose Grain Aphids. Results demonstrated that the highest application rate (100 t.d.s.

Characterization of the dynamic microbiome evolution across thrips species

open access: yesInsect Science, EarlyView.
Comprehensive survey of the microbiome in thrips. The dominant bacterial genera found in thrips include intracellular ones, such as Wolbachia and Spiroplasma, and extracellular ones, including Serratia, Pantoea, and Acinetobacter. We isolated and sequenced high‐quality genomes of two dominant symbionts, Pantoea dispersa and Serratia marcescens.

Nutrition Rather Than Phytohormone-Dependent Defense of Host Plant Mediates the Different Response of Red- and Green-Morph Pea Aphids to Nitrogen Fertilization

open access: yesAgronomy
Nitrogen fertilization is widely known to affect plant metabolism, which subsequently influences phytophagous insects through a bottom-up effect. The interplay between plants and insects is often overlooked in studies examining the effects of nitrogen ...

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.

Assessing the host plants of the invasive apricot aphid, Myzus mumecola (Hemiptera: Aphididae)

open access: yesAgricultural and Forest Entomology, EarlyView.
We investigated the host plants of the invasive apricot aphid Myzus mumecola (Hemiptera: Aphididae), an emerging pest species in Europe, by combining molecular and ecological approaches. The winter host plant was confirmed as apricot by both methods.
