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. Of those aphid species, Baker (2015) lists 21 as occurring in Britain
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. Several of the colonies were comprised mainly of immatures (see picture below). Adult winged mustard aphid, Lipaphis erysimi. Both nymphs and adults suck the sap from leaves, buds and pods. 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. Large aphid populations can affect leaf size and yield. 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 Introduction.

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.) is an important winter oilseeds crop of India.Mustard aphid, Lipaphis erysimi (Kalt.) Of those aphid species, Baker (2015) lists 12 as occurring in Britain
Photo 2. A final transcriptome comprising 52,652 transcripts of 1064bp average length and N50 value of 1806 bp was generated. Micrographs of clarified mounts by permission of Roger Blackman, copyright AWP all rights reserved. Winged aphid in middle. 1977. has been found to be great hindrance and cause severe reduction to rapeseed and mustard. The studies on the relative occurrence and abundance of mustard aphid, Lipaphis erysimi (Kalt.) Response of mustard aphid, Lipaphis erysimi (Kalt.) 66, No. 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. = 1 × 109 spores/ml) at 3.3 ml/l water, Varunastra (Verticillium lecanii spores 2% aqueous suspension, 2 × 108 CFU/ml) at 6 ml/l water, Mahastra (Bacillus thuringiensis var. The body length of adult Lipaphis erysimi apterae is 1.4-2.4 mm. We especially thank Alan Outen, Bedfordshire Invertebrate Group, and Chris Shortall, Rothamsted Research, for permission to reproduce Alan's photo of a Lipaphis erysimi alate and for information about the colony. Mustard aphid (Lipaphis erysimi) and English grain aphid (Sitobion avenae) are among the most important pests in mustard and wheat fields in Nepal.
Despite the lateness of the year, there was no sign of any sexual forms and the aphids were reproducing viviparously (see picture below). They are known as "mummies". INTRODUCTION. Common names. The swollen mustard aphids, Lipaphis erysimi, have been parasitised. A total of 27,112 transcripts were annotated with insect proteins from SwissProt, of which 4128 transcripts were components of 165 KEGG pathways. MATERIALS AND METHODS The aphids were cultured on greenhouse grown radish plants. was the most abundant species on the crop. On Mustard With Special Reference … RH 15(2): 29-32. to allylisothiocyanate. Blackman & Eastop list 15 species of aphid as feeding on those 3 species, and all Sinapis worldwide, and provide formal identification keys
