Large populations of natural enemies are the basis for natural pest control. Effects of mulch on predator–prey interactions in arable fields are poorly known, despite its potential to enhance ground‐dwelling predators and thereby reduce pest infestations. We studied the densities of predators and parasitoids, and their impact on cereal aphids in the presence and absence of mulch. Released populations of the bird cherry aphid, Rhopalosiphum padi (L.) (Homoptera: Aphididae), and two naturally… 

The Role of Natural Enemy Foraging Guilds in Controlling Cereal Aphids in Michigan Wheat

TLDR
Overall, the results suggest that, in combination, natural enemies can almost completely halt early-season aphid population increase.

Effect of Conservation Agriculture on Aphid Biocontrol by Generalist (Carabid Beetle) and Specialist (Parasitoids Wasp) Natural Enemy Communities in Winter Wheat

Adoption of practices that reduce the risk of pest outbreaks is one of the pillars of agroecology and is largely based on biological control. Multiple infield and landscape parameters affect

Implications of Russian wheat aphid, Diuraphis noxia, falling rates for biological control in resistant and susceptible winter wheat

TLDR
This study calculated the falling rate of the Russian wheat aphid, Diuraphis noxia (Kurdjumov) (Sternorrhyncha: Aphididae), and tested whether this aphid more likely fell from wheat plants that differed between flat leaf architecture versus those with furled leaves, to quantify such behavior as aphid falling rate.

Density estimation of ground-dwelling predators in wheat fields of northwest China.

TLDR
Results showed that natural enemies abundance was negatively correlated with aphid densities, indicating predator did not exhibit a numerical response to cereal aphids, which could be helpful for management of cereal aphid management by exploiting ground-dwelling predators as biological agent in wheat fields.

Cursorial spiders retard initial aphid population growth at low densities in winter wheat

TLDR
The results suggest that manipulating the community composition in favour of pest-consuming functional groups may be more important for improving biological control than fostering predator biodiversity per se.

Intercropping hampers the nocturnal biological control of aphids

TLDR
It is indicated that intercropping non-flowering companion plants is likely enough to mediate an increase of natural enemies via shelter provision, and the results suggest that nocturnal predators, or non-flying predators for that matter, are hampered by complex lower stratum vegetation.

Relative importance of predators and parasitoids for cereal aphid control

TLDR
The great importance of parasitism is a new finding for aphid control in cereal fields and more detailed knowledge of the mechanisms of natural pest control would help to develop environmentally sound crop management with reduced pesticide applications.

TLDR
Field evidence for intraguild interference among generalist ground predators in arable land is provided, despite this interference the polyphagous predator community was able to depress numbers of aphids in winter wheat, a result cascading down to plant quality parameters.

Release of Aphidius rhopalosiphi (Hymenoptera : Aphidiinae) for cereal aphid control: field cage experiments

TLDR
The parasitoid Aphidius rhopalosiphi seemed to be a good control agent in field cages, provided they were released at the beginning of aphid population growth.

Quantifying the impact of polyphagous invertebrate predators in controlling cereal aphids and in preventing wheat yield and quality reductions

TLDR
Exclusion barriers were used to manipulate numbers of polyphagous invertebrate predators so that their impact on cereal aphids and consequently wheat yield and quality could be examined and some negative correlations were found between these groups of polyPHagous predators and aphids.

Predator density manipulation and its effects on populations of Rhopalosiphumpadi (Horn.: Aphididae) in spring barley

TLDR
It was concluded that differences between the manipulated numbers of polyphagous predators caused the observed differences in peak population levels of R.padi in 1981, 1982 and to a lesser extent, 1983.

Predators and mutualists influence the exclusion of aphid species from natural communities

TLDR
It is concluded that the absence of the two species of aphid in the study site is influenced by the resident predator community, and by the availability of mutualists.

The effects of predator exclusion and caging on cereal aphids in winter wheat.

TLDR
It was concluded that predation was likely to be the major cause of the differences between cages and outside to the time of the population peak, and Predation, parasitism, disease and emigration all contributed to the decline phase.

Improved methods of testing and release of Aphidoletes aphidimyza (Diptera: Cecidomyiidae) for aphid control in glasshouses

TLDR
The gallmidge Aphidoletes aphidimyza is used commercially to control aphids infesting greenhouse crops such as sweet pepper and tomato and several different ways of improving its use as a biocontrol agent are investigated.

The effectiveness of exclusion barriers for polyphagous predatory arthropods in wheat

TLDR
The enclosures were effective in reducing most species of Carabidae, Linyphiidae and Lycosidae encountered and numbers in pitfall traps were reduced by an average of 74%, 62% and 77% respectively, and similar reductions in densities of these taxa were found.
