2. These aspects of the foraging behaviour of the aphidophagous hoverfly (Episyrphus balteatus De Geer) larvae were investigated in the present study. United Kingdomâs most common hoverfly, Episyrphus balteatus is a comparatively small hoverfly of the Syrphidae family. Request. The larvae of hoverfly Episyrphus (De Geer) are important predators for controlling the aphids in cruciferous vegetable fields in Hanoi. Results: Male and female antennal transcriptomes of Episyrphus balteatus and Eupeodes corollae were sequenced and assembled using Illumina HiSeq2000 technology. Data sheet. As in most other hoverflies, males can be easily identified by their holoptic eyes, i.e., left and right compound eyes touching at the top of their heads. Here, we used recent transcriptome data for the common hoverfly, Episyrphus balteatus, to characterize key molecular components of chemoreception: odorant-binding â¦ The upper side of the abdomen is patterned with orange and black bands. Description. The hoverfly Episyrphus balteatus (Degeer) is one of the most abundant predators of the cabbage aphid (Brevicoryne brassicae (L.)) in brussels sprouts in Belgium. CORE is a not-for-profit service delivered by They often form dense migratory swarms, which may cause panic among people for their resemblance to wasps. The larvae of this species feed on more than 100 species of aphids worldwide ( Sadeghi and Gilbert, 2000 ). Marmalade Hoverfly - Episyrphus balteatus. Mature hoverflies feed on nectar and pollen, while the larvae are gluttonous predators. All the 50 larvae were daily provided by 20, 50, and 100 individuals of aphid during their 1st, 2nd, and 3rd instars, respectively. Security sheet. Although pupation and adult hatching rates were strongly reduced compared with hoverflies continuously fed with aphids, the consumption of non-prey food most probably increases the probability that hoverfly larvae find an aphid colony and complete their development.
