“…Hoverfly females can recognize a suitable aphid colony at which they lay eggs (Kan and Sasakawa, 1986;Kan, 1988a, b), and they might have similarly strong oviposition preferences for sites in relation to intraguild predators. However, there are no studies to support this hypothesis (Gilbert, 2005).…”

Two experiments were performed in the laboratory to understand the relationships between oviposition preference and larval performance of the two predatory hoverfly species, Episyrphus balteatus de Geer and Metasyrphus corollae Fabricius. We first conducted laboratory experiments to understand the nature and relative strengths of intraguild predation between the larvae of three ladybird species, Harmonia axyridis Pallas, Propylea japonica Thunberg, and Scymnus posticalis Sicard, and two predatory hoverfly species. The interactions between larvae of the three ladybird and two hoverfly species differed depending on the species and developmental stages involved: the relationships between H. axyridis or S. posticalis and the two hoverfly larvae tended to be asymmetric with H. axyridis being a superior species and S. posticalis an inferior species, although the reverse was true for each of these two species when small larvae were paired with large larvae of the hoverflies. The ladybird, P. japonica, had both asymmetric and symmetric relationships depending on the hoverfly species with which it interacted. Secondly, we tested the preference and performance hypothesis for hoverflies, 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. Oviposition preference in relation to larval performance of the two hoverflies differed between the species: E. balteatus females tended to adjust their rate of eggs laying in response to the presence of ladybird larvae, while similar responses of M. corollae females were weak. The relationship between oviposition preference and larval performance in hoverflies is discussed.

“…Aphid natural enemies such as hoverflies (Gilbert 1986(Gilbert , 2005, coccinellid beetles (Hodek and Honek 1996), lacewings (Principi and Canard 1984), cecidomyiid midges (Nijveldt 1988), spiders (Sunderland et al 1986) and parasitoids (Stáry 1970), are major components of the natural enemy guild associated with aphid colonies. Hoverflies are efficient aphidophagous predators (Alhmedi et al 2008).…”

Trichome-based tomato resistance offers the potential to reduce pesticide use, but its compatibility with biological control remains poorly understood. We evaluated Episyrphus balteatus De Geer (Diptera, Syrphidae), an efficient aphidophagous predator, as a potential biological control agent of Myzus persicae Sulzer (Hemiptera, Aphididae) on trichome-bearing tomato cultivars. Episyrphus balteatus' foraging and oviposition behavior, as well as larval mobility and aphid accessibility, were compared between two tomato cultivars (Lycopersicon esculentum Mill. 'Moneymaker' and 'Roma') and two other crop plants; broad bean (Vicia faba L.) and potato (Solanum tuberosum L.). Hoverfly adults landed and laid more eggs on broad beans than on three species of Solanaceae. Hoverfly larval movement was drastically reduced on tomato, and a high proportion of hoverfly larvae fell from the plant before reaching aphid prey. After quantifying trichome abundance on each of these four plants, we suggest that proprieties of the plant surface, specifically trichomes, are a key factor contributing to reduced efficacy of E. balteatus as a biological agent for aphid control on tomatoes.

“…Many are astonishingly close mimics of aculeate Hymenoptera and, in general, syrphids are useful models for a variety of ecological research (e.g. Bartsch 2009aBartsch , 2009bGilbert 2005aGilbert , 2005bGittings et al 2006;Marinoni et al 2004;Montoya et al 2012;Penney et al 2012). It is for all of these reasons that there is currently a great deal of interest in Syrphidae amongst photographers, naturalists and professional biologists, all of whom share a common need to correctly and efficiently identify flower flies at least to the generic level.…”
