چکیده

Three species of Episyrphus (Episyrphus) Matsumura, 1917 are here recorded in Australia: E. (E.) viridaureus (Wiedemann, 1824) and two new species E. (E.) oliviae Wright sp. nov. and E. (E.) glaber Wright sp. nov. A key to Australian Episyrphus (Episyrphus) species is provided, important taxonomic characters are illustrated and distributions of the three species are mapped. The distribution of E. (E.) viridaureus is extended to include Australia. Mitochondrial cytochrome c oxidase subunit I (COI) data are provided from some Episyrphus species to test morphological species concepts.

Mitochondrial genomes of the hoverflies Episyrphus balteatus and Eupeodes corollae (Diptera: Syrphidae), with a phylogenetic analysis of Muscomorpha

The hoverflies Episyrphus balteatus and Eupeodes corollae (Diptera: Muscomorpha: Syrphidae) are important natural aphid predators. We obtained mitochondrial genome sequences from these two species using methods of PCR amplification and sequencing. The complete Episyrphus mitochondrial genome is 16,175 bp long while the incomplete one of Eupeodes is 15,326 bp long. All 37 typical mitochondrial g...

Evidence for a composite anterior determinant in the hover fly Episyrphus balteatus (Syrphidae), a cyclorrhaphan fly with an anterodorsal serosa anlage.

Most insect embryos develop from a monolayer of cells around the yolk, but only part of this blastoderm forms the embryonic rudiment. Another part forms extra-embryonic serosa. Size and position of the serosa anlage vary between species, and previous work raises the issue of whether such differences co-evolve with the mechanisms that establish anteroposterior (AP) polarity of the embryo. AP pol...

Estimating Predatory Efficiency of Episyrphus balteatus (Diptera: Syrphidae) in Cereal Fields

A model was developed to estimate the effect of predation by Episyrphus balteatus larvae on aphid populations in fields of winter wheat. Feeding rate of syrphid larvae was estimated from experiments in field cages using a Holling type-III function. During larval development, syrphids consumed a maximum of 396 aphids, which is only half the potential feeding rate reported from laboratory experim...

Oviposition behaviour and host colony size discrimination in Episyrphus balteatus (Diptera: Syrphidae).

Three bioassays were used to examine the oviposition behaviour of the hoverfly, Episyrphus balteatus (Degeer) in which various stimuli purported to influence host assessment and choice were tested. Episyrphus balteatus failed to exhibit enhanced behavioural responses, in terms of approaches and landings, to artificial leaves with the highest numbers of aphids, suggesting that females are merely...
