1. The fitness consequences of feeding on different aphids (apple, blackberry, dock, elder, nettle, pea, rose and sycamore aphids) for two species of generalist insect predator (the aphidophagous larvae of Episyrphus balteatus and Syrphus ribesii- Diptera:Syrphidae) were measured in the laboratory. The relevant literature studies on prey specialization in the Syrphidae were summarized for the first time. 2. Both the literature evidence reviewed and the data from the experiment indicated that…

Preference-performance of a generalist predatory ladybird: A laboratory study

Predatory hoverflies select their oviposition site according to aphid host plant and aphid species

The results demonstrated the importance of the prey–host plant association on the choice of the oviposition site by an aphid predator, which is here shown to be related to offspring fitness.

Feeding History Affects Intraguild Interactions between Harmonia axyridis (Coleoptera: Coccinellidae) and Episyrphus balteatus (Diptera: Syrphidae)

The results from this study show that IGP interactions are influenced by a multitude of factors, including feeding history of the organisms involved, and emphasize the importance of taking these factors into account in order to fully understand the ecological relevance of IGP.

Aphid suitability for the predatory hoverfly Episyrphus balteatus altered with elevating atmospheric CO2 and sinigrin

Study of the effect of different CO2 levels on the aphid predator Episyrphus balteatus DeGeer fed either specialist or generalist aphids reared on either of two host plants under laboratory conditions found fitness decreased slightly and consumption rate was influenced significantly by plant and prey solely.

Predatory behavior of Pseudodorus clavatus (Diptera, Syrphidae) on aphids tended by ants

It is suggested that behavioral and chemical cues are involved in the infiltration and in the successful predation of syrphids upon aphids and on the successfulPredatory behavior of Pseudodorus clavatus on aphids tended by ants.

Oviposition preference of two hoverfly species in response to risk of intraguild predation.

The preference and performance hypothesis for hoverflies was tested, by determining whether hoverfly oviposition preference was related to the risk of intraguild predation posed by the presence of a ladybird larva in an aphid colony.

Ecological and life-history notes on syrphid predators of woolly apple aphid in Virginia, with emphasis on Heringia calcarata

The developmental duration of the immature stages of H. calcarata was determined under laboratory conditions, revealing a generation time of 19–20 d at 25°C, and the potential role of predation by aphidophagous hover flies on the suppression of woolly apple aphid outbreaks in eastern apple orchards is discussed.

Functional response and effects of prey species, Acyrtosiphon pisum (Harris) and Aphis craccivora Koch, and its density on larval performance such as survival rate and development time in addition to




An adequate prey supply is also necessary to obtain syrphid colonies with greater pupa! weight, larval survival rate and adult emergence rate, although 80 aphid nymphs were satisfactory for a M. corollae larva to complete its normal development.

Prey Specificity in Chrysopa: An Interspecific Comparison of Larval Feeding and Defensive Behavior

To examine pathways in the evolution of prey specialization in insects, we conducted a comparative experimental analysis of larval behavior in two sympatric pre- dacious sister-species (Chrysopa

Individual variation in oviposition preference, and its interaction with larval performance in an insect predator

Individual female Episyrphus balteatus (DeGeer) (Diptera: Syrphidae) show different oviposition preferences when presented with two aphid prey species, suggesting that natural selection has responded to the nutritional value of prey.

Some factors influencing the occurrence and site of oviposition by aphidophagous Syrphidae (Diptera)

Syrphids were not deterred from ovipositing on suitable plants by the presence of other syrphid eggs, larvae or larval gut contents, and flowers, a source of adult food, stimulate oviposition nearby.

Prey finding by larvae and adult females of Episyrphus balteatus

The prey‐location behaviour of larvae of Episyrphus balteatus DeG. (Dipt.: Syrphidae) was investigated in two different experimental set‐ups. First instar larvae exhibited directed search over short

Results corroborate the avoidance of unsuitable host plants seen in the genetic analyses of individuals, but relative to the genetic data, such population‐level data are of limited usefulness in the study of evolutionary mechanisms by which insect populations become adapted to their host plants.

Developmental threshold, day-degree requirements and voltinism of the aphid predator Episyrphus balteatus (Diptera: Syrphidae).

The effects of temperature on the developmental rate of E. balteatus were investigated to determine the potential voltinism of this species in the UK and indicate that one to three generations are possible each year, depending on the available DD and origin of the population.

The relationship between aphid infestations and oviposition by aphidophagous Syrphidae (Diptera)

SUMMARY Oviposition by aphidophagous Syrphidae varies with the size of aphid infestations and different syrphid species have different optimum aphid population sizes for oviposition. In one

Escape responses of the pea aphid, Acyrthosiphon pisum (Harris) (Homoptera: Aphididae): influence of predator type and temperature

It is found that most aphids dropped off the host plant when confronted by coccinellid beetles, especially at higher temperatures, and backed up when confronted with syrphid larvae regardless of temperature, which depends on the foraging rate and species of predator.

Evolutionary ecology of the relationship between oviposition preference and performance of offspring in phytophagous insects

Understanding of the relationships between oviposition preference and growth, survival, and reproduction of offspring is hampered by an almost complete lack of data on how preference and performance are related genetically.
