In the present study, RiD was highly upregulated in R. indica during aphid infestation initiating a defense system mediated by jasmonic acid (JA), but not by salicylic acid (SA)/abscisic acid (ABA). Keeping the lack of information on the efficacy of this fungus on this particular aphid species, it was proposed to study the management aspects of mustard aphid, Lipaphis erysimi by use of different dosages of this fungus. has been found to be great hindrance and cause severe reduction to rapeseed and mustard. 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. Department of Botany, University of Delhi, Department of Botany, Deshbandhu College, University of Delhi, De novo transcriptome profiling of mustard aphid (Lipaphis erysimi) and differential expression of transcripts associated with developmental stages, feeding and non-feeding conditions. (2020). Annals of Plant Protection Sciences. 1977. Mustard aphid (Lipaphis erysimi) and English grain aphid (Sitobion avenae) are among the most important pests in mustard and wheat fields in Nepal. was the most abundant species on the crop. This is an exploratory study with no biological replicates. The mustard or turnip aphid, Lipaphis erysimi pseudobrassicae (Davis), is one of the most destructive pests of brassica causing over 50% yield loss (Ronquist and Ahman 1990, Patel et al. Abstract. A total of 17,296 transcripts were classified based on their Gene Ontology. Mustard aphid, Lipaphis erysimi (Kaltenbach) is a major constraint in increasing the yield of rapeseed-mustard crops in India. Enter multiple addresses on separate lines or separate them with commas. Pacific Pests and Pathogens - Fact Sheets The mustard aphid, Lipaphis erysimi (Kalt. 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. Incidence of aphid during re productive stage of m ustard causes severe 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. Adult apterae of Lipaphis erysimi are small to medium sized yellowish green, grey green or olive green aphids, with a faint white wax bloom. with combination of … The combined length of antennal segment III and the terminal process is usually less than 2.4 times the length of the siphunculus (cf.

(Show British list). Blackman & Eastop list 25 species of aphid as feeding on Brassica species worldwide, and provide formal identification keys Its efficacy as a tool of biological control of mustard aphid, Lipaphis erysimi was tested under field conditions for two consecutive years. Thank you for your interest in spreading the word about bioRxiv. Then in mid-October 2018 we found colonies of wild crucifer aphid on seed heads of hedge mustard (Sisymbrium officinale, see picture below). 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. Krishnaiah, K. and N. Jagan Mohan. Photo 3. Common names. It is by Alton N. Sparks, Jr. at University of Georgia. (Show World list). J. Insect Sci. Adult mustard aphid, Lipaphis erysimi.

A final transcriptome comprising 52,652 transcripts of 1064bp average length and N50 value of 1806 bp was generated. L. erysimi is a serious pest of mustard in India. 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.) Potential transcripts for host selection, detoxification, salivary proteins and effectors, molecular chaperones and developmental genes were identified. 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. Blackman & Eastop list 15 species of aphid as feeding on those 3 species, and all Sinapis worldwide, and provide formal identification keys 2010-2016b; 18(2):333-335. Distribution. 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. This is the subject of investigation. Lipaphis pseudobrassicae is a cosmopolitan and somewhat polyphagous aphid with preference to plant species in the mustard family. Then in late October we found much bigger colonies of Lipaphis erysimi on seedheads of shepherd's purse (Capsella bursa-pastoris). kurstaki 0.5% wettable powder) at 6 g/l water, Neemraj Super (Az… They are known as "mummies".

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. RiD was found to have an effective insecticidal property against mustard aphid, Lipaphis erysimi. On Mustard With Special Reference … We fully acknowledge these authors as the source for the (summarized) taxonomic information we have presented. Several of the colonies were comprised mainly of immatures (see picture below). is an important winter oilseeds crop of India.Mustard aphid, Lipaphis erysimi (Kalt.) The siphunculi are paler than the cauda and have dark tips. 15(2): 29-32. 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. This could also allow identification of novel target genes for development of RNAi-based aphid control methods. The functional response of fourth instars, adult males and females of the sevenspotted lady beetle, Coccinella septempunctata Linnaeus (Coleoptera: Coccinellidae), was studied at different densities of aphid, Lipaphis erysimi (Kaltenbach) (Homoptera: Aphididae). The insecticides used are acetamiprid 20 SP (125 g/ha) and imidachloprid 17.8 SL (150 ml/ha). 1979. ), is a pest of cruciferous plants throughout the world but no information is available on its metabolic requirements or the composition of the honeydew. Adult mustard aphid, Lipaphis erysimi. In the great majority of cases, identifications have been confirmed by microscopic examination of preserved specimens. Rapeseed and mustard are one of the most important oilseed crops in Jammu and Kashmir as they rank second to cereals. These however were mixed species colonies comprised of Lipaphis erysimi, Aphis fabae and Myzus persicae (see picture below). Mustard aphid, Lipaphis erysimi (L.)

This study reports the de novo transcriptome of L. erysimi for the first time. Entomopathogenic fungi, Verticillium lecani has been considered to be pathogenic to a wide range of insect-pests including aphids, thrips and white fly (Brownbridge, 1995; Hall and Burges, 1979; Hall, 1982; Heyler, Gill, Baywater and Chambers, 992). 4. Lipaphis erysimi is a Brassicaceae specialist aphid, which causes significant losses in yield and/or reduction of oil content of vegetable and oilseed brassicas and is a major pest in the Indian subcontinent. Despite the lateness of the year, there was no sign of any sexual forms and the aphids were reproducing viviparously (see picture below). MATERIALS AND METHODS The aphids were cultured on greenhouse grown radish plants. Chemical control of mustard aphid with newer and conventional insecticides. Micrographs of clarified mounts by permission of Roger Blackman, copyright AWP all rights reserved. A total of 20441 found to share no homology to any sequence available in the public domain and could therefore represent novel aphid genes or sequences that are unique to L. erysimi. The losses in yield by mustard aphid were 66-96% (Singh and Sachan, 1997). Large aphid populations can affect leaf size and yield. Mustard aphid: Lipaphis erysimi. Kawada, K. and T.
