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. Short Communication. crop in tropical and sub-tropical climate.Cultivated Brassica germplasm has failed so far to provide any source of resistance. This is the subject of investigation. Winged aphid in middle. It lives on the undersides of leaves as well as on inflorescences, young shoots and growing points. 4. 6. Then in mid-October 2018 we found colonies of wild crucifer aphid on seed heads of hedge mustard (Sisymbrium officinale, see picture below). Mustard aphid, Lipaphis erysimi (L.) Kaltenbach is a perpetual annual threat in the cultivation of rapeseed- mustard (Brassica spp.) This question is for testing whether or not you are a human visitor and to prevent automated spam submissions. This is an exploratory study with no biological replicates. Pacific Pests and Pathogens - Fact Sheets 99-105. The siphunculi are paler than the cauda and have dark tips. 26: 343-345. Lipaphis erysimi is confined to Britain and northern continental Europe. The antennal terminal process is 0.8-1.15 times times the length of the siphunculi (cf. The peak populations (42.7) and (28.7) per leaf on Rainbow and Oscar varieties were recorded. Aphids (Lipaphis erysimi Kaltenback) often reduce mustard (Brassica juncea L.) yield in India.This study was conducted to determine if intercropping with aromatic plant species could provide an environmentally safe method for aphid control. The clarified slide mounts below are of adult viviparous female Lipaphis erysimi : wingless, and winged. 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. The mustard aphid, Lipaphis erysimi (Kalt. Common names. has been found to be great hindrance and cause severe reduction to rapeseed and mustard. Blackman & Eastop list 18 species of aphid as feeding on those 2 species, and all Raphanus worldwide, and provide formal identification keys 2, pp. 2004, Carter and Sorensen 2013, Adhab and Schoelz 2015). Modelling regional level spatial distribution of aphid (Lipaphis erysimi) growth in Indian mustard using satellite-based remote sensing data. Of those aphid species, Baker (2015) lists 12 as occurring in Britain International … Both nymphs and adults suck the sap from leaves, buds and pods. A final transcriptome comprising 52,652 transcripts of 1064bp average length and N50 value of 1806 bp was generated. (Show World list). INTRODUCTION. Plants remain stunted and sooty molds grow on the honey dew excreted by the insects. with combination of … They are known as 'mummies'. Pesticides. Rapeseed and mustard are one of the most important oilseed crops in Jammu and Kashmir as they rank second to cereals. Large aphid populations can affect leaf size and yield. Adult mustard aphid, Lipaphis erysimi. ), is a pest of cruciferous plants throughout the world but no information is available on its metabolic requirements or the composition of the honeydew. is one of the most damaging of biotic stresses that confront this crop. Note the green bands on the back of the aphid. 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. This could also allow identification of novel target genes for development of RNAi-based aphid control methods. However, the significant repertoire of feeding- and development-related genes and their differential expression profiles generated in this study adds to the limited data available on L. erysimi and it would facilitate studies on the molecular basis of aphid feeding and development. Blackman & Eastop list 15 species of aphid as feeding on those 3 species, and all Sinapis worldwide, and provide formal identification keys Curling may occur in infested leaves and at advanced stage plants may wither and die. is an important winter oilseeds crop of India.Mustard aphid, Lipaphis erysimi (Kalt.)

L. erysimi is a serious pest of mustard in India. Mustard aphid (Lipaphis erysimi) and English grain aphid (Sitobion avenae) are among the most important pests in mustard and wheat fields in Nepal. RiD was found to have an effective insecticidal property against mustard aphid, Lipaphis erysimi. It is the most destructive of all the pests of mustard in Bangladesh (Alam et al., 1964; Ahmed et al., 1977; Haque & Miah, 1979) and reduces the yield of mustard considerably. 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: Symptoms of damage. Lipaphis pseudobrassicae in which that combined length is usually more than 2.4 times as long as the siphunculus). is very devastating. RH 66, No. Mustard aphid: Lipaphis erysimi. It feeds on various different Brassicaceae, including Brassica, Raphanus, and Sinapis spp., although it is not usually found on field Brassica crops. NOTE: Your email address is requested solely to identify you as the sender of this article. We also present a comparative analysis of nymphs and adult transcriptomes to study the differential expression profiles associated with different developmental stages as well as different feeding conditions. In the great majority of cases, identifications have been confirmed by microscopic examination of preserved specimens. (2008). The more feeding of plant sap by aphid, the more secretion of honeydew. The copyright holder for this preprint is the author/funder, who has granted bioRxiv a license to display the preprint in perpetuity.

This study reports the de novo transcriptome of L. erysimi for the first time. Despite the lateness of the year, there was no sign of any sexual forms and the aphids were reproducing viviparously (see picture below). The wild crucifer aphid does not host alternate. For assistance on the terms used for aphid morphology we suggest the figure provided by Blackman & Eastop (2006). was the most abundant species on the crop. Lipaphis erysimi. Then in late October we found much bigger colonies of Lipaphis erysimi on seedheads of shepherd's purse (Capsella bursa-pastoris).

Distribution. BSH 1 and Indian mustard, Brassica juncea cv. Determination of the amount of honeydew secreted by aphids in a specific crop variety is one of the best ways to assess the susceptibility of aphid infestation to the variety. MATERIALS AND METHODS The aphids were cultured on greenhouse grown radish plants. The aptera (see first picture below) has two rows of dark bands on the thorax and abdomen which unite into a single band near the tip of the abdomen. It is by Alton N.
