Repellency, Toxicity, Gene Expression Profiling and In Silico Studies to Explore Insecticidal Potential of Melaleuca alternifolia Essential Oil against Myzus persicae

open access: yesToxins, 2018
In the current study, deterrent assay, contact bioassay, lethal concentration (LC) analysis and gene expression analysis were performed to reveal the repellent or insecticidal potential of M. alternifolia oil against M. persicae. M.

Target‐site mutations and phenotypic failure in Myzus persicae against pyrethroids and carbamates in central Europe

open access: yesPest Management Science, EarlyView.
Molecular screening of 140 field‐collected Myzus persicae aphids revealed target‐site mutations L1014F, M918L, M918T, and L932F in the sodium channel and S431F in Ace2. The M918L mutation was the primary driver of high pyrethroid (cypermethrin) resistance, while S431F served as a definitive marker for carbamate (pirimicarb) resistance.

Soybean Aphid in Minnesota [PDF]

open access: yes, 2003
The soybean aphid (Aphis glycines) is an eastern Asian soybean pest that is rapidly invading the United States. A recent immigrant, it was first detected in nine midwestern states including Minnesotain the summer of 2000.

Development and deployment of a risk assessment index as a decision‐support tool for managing whitefly‐transmitted viruses affecting squash

open access: yesPest Management Science, EarlyView.
A data‐driven framework identified planting date and row cover as dominant drivers of whitefly‐transmitted virus complex (WTVC) risk in squash. Integration into the SquashRx mobile application enables real‐time risk assessment and supports improved decision‐making for integrated pest management.

Soybean plant architecture influences the capacity of Telenomus podisi to parasitize Euschistus heros eggs: implications for field releases

open access: yesPest Management Science, EarlyView.
Increasing soybean plant architectural complexity reduces the ability of Telenomus podisi to parasitize Euschistus heros eggs, highlighting the need to adjust parasitoid release rates in the field according to plant complexity (arrow direction and thickness correspond to the increasing strength of the variable) . Abstract BACKGROUND Plant architectural

Integrating bioassays and transcriptomics to detect neonicotinoid resistance in Australian Bemisia tabaci MEAM1

open access: yesPest Management Science, EarlyView.
The Bemisia tabaci MEAM1 strain GR15‐1R shows partial resistance to neonicotinoids (bottom), which correlates with an increased expression of the P450 gene CYP6CM1 compared to the insecticide‐susceptible strain SU07‐1 (top). Abstract BACKGROUND Bemisia tabaci MEAM1 is a highly invasive and polyphagous pest species of agricultural and horticultural ...

New structure in cell puncture activities by aphid stylets: a dual-mode EPG study [PDF]

open access: yes, 2010
Intracellular punctures by aphid stylets appear as potential drop (pd) waveforms in DC electrical penetration graph (EPG) recordings. We used a dual-EPG device that recorded in one channel the ‘full EPG’ with R-plus emf-components (i.e., the usual DC EPG)
