In Britain alone, some 46 species belong to the Coccinellidae family, although only 26 of these are recognisably ladybirds.

The overwintering biology of the hoverfly Episyrphus balteatus (DeGeer) (Diptera: Syrphidae) was studied and analysed. In Europe, females of this species can overwinter as adults in The hoverfly Episyrphus balteatus: biology and mode of life Episyrphus balteatus DeGeer (Diptera: Syrphidae) is one of the best-studied aphidophagous :// Episyrphus balteatus is an important pollinator and the larvae are efficient aphid predators, playing a significant role in the biocontrol of agricultural crop pests [31 ].

Episyrphus balteatus and Scaeva selenitica are two common hoverfly species that are widespread in Central Europe (Speight, ).Both species feed on aphids as larvae and pollen and nectar as adults.
Although wild populations may survive longer, evidenced by the overwintering females, the average longevity in the laboratory is 7–9 days, depending on the food type (Pinheiro, Torres, Raimundo A 3-year research project was started in on two differently structured sites in northern Germany to determine whether an autochthone overwintering syrphid population exists.
Another aim was to examine the influence of habitat structure (hedges) on oviposition in spring and on population dynamics.

Lack of genetic differentiation between E. balteatus overwintering strategies Episyrphus balteatus specimens were collected at seven sites located across Western Europe to establish a gradient of δD ratio In this study, the complete mitochondrial genomes (mitogenomes) of two hoverfly species of Korinchia angustiabdomena (Huo, Ren, and Zheng) and Volucella nigricans Coquillett (Diptera: Syrphidae) were determined and analyzed.

The hoverfly Episyrphus balteatus (DeGeer) (Diptera: Syrphidae) is one of the most important natural predators of crop aphids in Europe. Three different overwintering strategies coexist in this species which makes it a good model in order to study ecologically-based speciation Abstract.
Larvae of the hoverfiy Episyrphus balteatus (DeGeer) are important predators of aphids in the U.K. A large proportion of the U.K.
population migrates south to warmer climes at the end of summer, but a small number are thought to overwinter in the U.K., with the mated female being the overwintering morph. The cold tolerance of adult flies was investigated to assess the overwintering Adult overwintering hoverflies are almost exclusively females that are in a facultative reproductive diapause, whereas males of E.
balteatus are thought to be unable to increase their fat bodies, and therefore are more susceptible to cold temperatures and are not expected to overwinter [34,35]. Partial migration, where a proportion of a population migrates, while other individuals remain resident, is widespread across most migratory lineages.
However, the mechanisms driving individual differences in migratory tendency are still relatively poorly understood in most taxa, but may be influenced by morphological, physiological, and behavioral traits, controlled by phenotypic plasticity A typical explanation for ecologically stable strategies that apply to only a proportion of a population, is bet hedging, where increased reproductive Speight MC.

In order to plan controlled release experiments in greenhouses or in the fields, reliable ecological data are necessary (Singh and Agarwala,Singh, ). Observed aphidophagous hoverflies in were Sphaerophoria scripta L., Sphaerophoria rueppellii (Wiedeman), and Episyrphus balteatus (DeGeer).
InEupeodes corollae (F.) specimens were also observed. Visual observations did not allow us to distinguish between the two species of the genus Sphaerophoria inhabiting the study :// Insects other than bees (i.e., non-bees) have been acknowledged as important crop pollinators, but our understanding of which crop plants they visit and how effective they are as crop pollinators is limited.

& SOTHERTON N.W. The selective use of floral resources by the hoverfly Episyrphus balteatus (Diptera: Syrphidae) on farmland. Ann. Honeydew is considered a cornerstone of the interactions between aphids and their natural enemies.
Bacteria activity occurring in aphid honeydew typically results in the release of volatile organic compounds (VOCs) that are used by the natural enemies of aphids to locate their prey. Because atmospheric carbon dioxide (CO2) concentration directly impacts the physiology of plants, we raise the Photoselective nets have proven to be effective for aphid pest control as they limit their dispersal ability.
However, little is known on the impact of such nets on natural enemies of aphids. In this work, we study the effect of UV-absorbing nets on the syrphid fly Sphaerophoria rueppellii Wiedemann (Diptera: Syrphidae), a commercially available aphid biocontrol agent in Mediterranean uction.
1 Although a good number of insects do not feed as adults, for the majority, most of their adult life is dedicated to actions related both to the acquisition of food and to reproduction, and crucial decisions must be taken concerning these two activities.
Oviposition behavior is a vital component of many aspects of insect biology (e.g. population dynamics, life history and ?id= Available translations into English.

The decline of pollinators in agricultural areas has been observed for some decades, this being partly due to landscape simplification in intensive agrosystems.
Diversifying agricultural landscapes by sowing flower strips within fields could reduce these adverse effects on biodiversity. In this context, the study presented here aimed at assessing and comparing the abundance and diversity of Holloway GJ, Marriott CG, Crocker HJ.
