The functional role of ants in no‐till cropping systems

Pest Management Science, EarlyView.
Ants provide valuable ecosystem services in tropical agriculture, but their roles in temperate row crops remain poorly understood. Conservation practices such as no‐till farming and cover cropping support ant communities that contribute to pest suppression, weed seed removal, and soil quality, which can increase crop productivity.

The first report of M918L (super‐kdr) and L932F voltage‐gated sodium channel mutations in the English grain aphid (Sitobion avenae)

Pest Management Science, EarlyView.
The study has identified mutations in the voltage gated sodium channel of the English grain aphid (Sitobion avenae) at M918 and L932, which have not been previously reported in this species. Abstract BACKGROUND The grain aphid, Sitobion avenae Fabricius (Hemiptera: Aphididae), is a vector of yellow dwarf viruses and an important pest of cereals.

Aphid Alarm Pheromone as a Cue for Ants to Locate Aphid Partners

PLoS ONE, 2012
The mutualistic relationships that occur between myrmecophilous aphids and ants are based on the rich food supply that honeydew represents for ants and on the protection they provide against aphid natural enemies. While aphid predators and parasitoids actively forage for oviposition sites by using aphid semiochemicals, scouts of aphid-tending ant ...

Sublethal herbicide exposure alters cotton susceptibility to aphid infestation

Pest Management Science, EarlyView.
Sublethal herbicide exposure altered cotton susceptibility to aphids. Aphid severity was highest when applications occurred at early vegetative stages and declined as the crop matured. In glasshouse, herbicide effects were dose‐dependent. Abstract BACKGROUND Herbicides remain vital tools for weed control, yet their effects can extend beyond weeds to ...

The effect of within-crop habitat manipulations on the conservation biological control of aphids in field-grown lettuce [PDF]

, 2011
Within-crop habitat manipulations have the potential to increase the biological control of pests in horticultural field crops. Wildflower strips have been shown to increase the abundance of natural enemies, but there is little evidence to date of an ...

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

Pest 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

Pest 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

Pest 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 ...
