Author(s): Bugg, Robert L; Colfer, Ramy G; Chaney, William E; Smith, Hugh A; Cannon, James | Abstract: Flower flies (also known as syrphids or hoverflies) are effective predators against aphids in California vegetable fields. Learn to recognize these aphid eaters and encourage them to help with your pest management. This publication describes syrphid flies and other natural enemies of aphids. It includes color photographs of the syrphid adults and larvae commonly seen in California vegetable crops.read more

Flower plantings increase wild bee abundance and the pollination services provided to a pollination-dependent crop
Brett R. Blaauw,Rufus Isaacs +1 more
TL;DR: It is suggested that provision of forage habitat for bees adjacent to pollinator-dependent crops can conserve wild pollinators in otherwise resource-poor agricultural landscapes.

Pesticide residues in conventional, integrated pest management (IPM)-grown and organic foods: insights from three US data sets Part A Chemistry, analysis, control, exposure & risk assessment
TL;DR: In this paper, an analysis of pesticide residue data was performed to describe and quantify differences between organically grown and non-organic fresh fruits and vegetables, and found that organic foods consistently had about one third as many residues as conventionally grown foods, and about one-half as many residue as found in IPM/NDR samples.

TL;DR: In this paper, the nutritional value of various types of plant-derived food for natural enemies, possible adverse effects on pest management, and the practical application of flowering plants in orchards, vegetables and field crops, agricultural systems where most research has taken place.
Journal ArticleDOI
Attractiveness of common insectary and harvestable floral resources to beneficial insects
TL;DR: Sweet alyssum consistently attracted the most hoverflies and the least bees, while potentially harvestable plants attracted few hoverflies, suggesting that plants should be screened for their attractiveness to not only the target biological control agent, but also to other potential competitors for floral resources.

Detecting pest control services across spatial and temporal scales
TL;DR: It is suggested that higher temporal resolution of data for natural enemy and pest abundance can reveal top–down control that is otherwise masked by seasonal and interannual variation in environmental factors.

Can generalist predators be effective biocontrol agents
TL;DR: A review of manipulative field studies showed that in approximately 75% of cases, generalist predators, whether single species or species assemblages, reduced pest numbers significantly and needed to find ways of disentangling the factors influencing positive and negative interactions within natural enemy communities in order to optimize beneficial synergies leading to pest control.

Influence of intraguild predation among generalist insect predators on the suppression of an herbivore population.
TL;DR: It is concluded that intraguild predation in this system is wide-spread and has potentially important influences on the population dynamics of a key herbivore.

The Ecology of Myzus persicae
TL;DR: There is a special need for the integrated control approach which will lower the numbers of the vector especially at times when viruses are spread, but biological control by natural enemies and by manipulating the host plant could also be enhanced in the crop.

Effects of agricultural diversification on the abundance, distribution, and pest control potential of spiders: a review
K. D. Sunderland,Ferenc Samu +1 more
TL;DR: It is suggested that spiders tend to remain in diversified patches and that extending the diversification throughout the whole crop (as in interspersed diversification) offers the best prospects for improving pest control.
