Lipaphis pseudobrassicae in which that combined length is usually more than 2.4 times as long as the siphunculus). (2020). The body length of Lipaphis erysimi alatae is 1.4-2.2 mm. Alatae (see second picture above) have a black head and thorax and a dusky green abdomen with black bands near the tip and conspicuous dark marginal sclerites. ), is a pest of cruciferous plants throughout the world but no information is available on its metabolic requirements or the composition of the honeydew. Characterization of α-amylase and its activity from mustard aphid Lipaphis erysimi (Kalt.) Rohilla HR, Bhatnagar P, Yadav PR. A total of 23,532 transcripts that remained unannotated were subjected to BLAST against aphid sequences available at AphidBase and a total of 3091 transcripts had hits with sequences of other aphids in the database, out of which 1380 had protein hits. The antennal terminal process is 0.8-1.15 times times the length of the siphunculi (cf. The combined length of antennal segment III and the terminal process is usually less than 2.4 times the length of the siphunculus (cf. Second image: Lipaphis erysimi alate, copyright Alan Outen & Rothamsted Research, all rights reserved. The body length of adult Lipaphis erysimi apterae is 1.4-2.4 mm. Of those aphid species, Baker (2015) lists 21 as occurring in Britain For assistance on the terms used for aphid morphology we suggest the figure provided by Blackman & Eastop (2006). Photo 2. Adult winged mustard aphid, Lipaphis erysimi. Resistance to mustard aphid infestation and its correlation to some physiological and biochemical traits in selected varieties of different Brassica species were studied. Micrographs of clarified mounts by permission of Roger Blackman, copyright AWP all rights reserved. revealed that aphid appeared on leaves during 3rd week of January and on the inflorescences during 2nd week of February and continued up to harvesting on both the varieties. This aphid is globally distributed, located in all … They are known as "mummies". Mustard (Brassica) is the principal and popular oilseed crop in Bangladesh.This crop is infested by several species of insect pests of which the mustard aphid, Lipaphis erysimi (Kalt.) The clarified slide mounts below are of adult viviparous female Lipaphis erysimi : wingless, and winged. Symptoms of damage: Both nymphs and adults suck the sap from leaves, buds and pods; Curling may occur in infested leaves and at advanced stage plants may wither and die; Plants remain stunted and sooty molds grow on the honey dew excreted by the insects; The infected field looks sickly and blighted in appearance Mustard aphid, Lipaphis erysimi (Kalt.) The mustard aphid, Lipaphis erysimi Kaltenbach, is a major pest in mustard growing regions of the wo rld. These however were mixed species colonies comprised of Lipaphis erysimi, Aphis fabae and Myzus persicae (see picture below). is very devastating. Intr oduction Mustard crop attacked by painted bug, mustard Saw fly, mustard aphid potato aphid, leaf miner, flea beetle, diamond-back moth, bihar hairy catterpiller, cabbage buter fly and tobacco caterpillar Among them, Mustard aphid. A total of 27,112 transcripts were annotated with insect proteins from SwissProt, of which 4128 transcripts were components of 165 KEGG pathways. Mustard aphid (Lipaphis erysimi) and English grain aphid (Sitobion avenae) are among the most important pests in mustard and wheat fields in Nepal. Turnip aphid adults and immatures. Rapeseed and mustard are one of the most important oilseed crops in Jammu and Kashmir as they rank second to cereals. Distribution. L. erysimi is a serious pest of mustard in India. Note the green bands on the back of the aphid. It is by Alton N. Sparks, Jr. at University of Georgia. (Show British list). Lipaphis erysimi is usually regarded as a relatively common aphid in Britain, but until recently we have found it to be rather scarce in southern England.
