mustard aphid, lipaphis erysimi

RiD was found to have an effective insecticidal property against mustard aphid, Lipaphis erysimi. Singh PK, 2006. International Journal of Pest Management: Vol. Introduction. Both nymphs and adults suck the sap from leaves, buds and pods. Mustard aphid (Lipaphis erysimi) and English grain aphid (Sitobion avenae) are among the most important pests in mustard and wheat fields in Nepal. Lipaphis erysimi is confined to Britain and northern continental Europe. @inproceedings{Mishra2003BioEcologyAM, title={Bio-Ecology And Management Of Mustard Aphid, Lipaphis Erysimi (Kali.) A total of 17,296 transcripts were classified based on their Gene Ontology. Several of the colonies were comprised mainly of immatures (see picture below). It is highly host specific, feeding exclusively on Brassica phloem sap. This study reports the de novo transcriptome of L. erysimi for the first time. Of those aphid species, Baker (2015) lists 15 as occurring in Britain (Show British list). International … Parasitized aphid (mummy) at bottom. Note the green bands on the back of the aphid. 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. Enter multiple addresses on separate lines or separate them with commas. The insecticides used are acetamiprid 20 SP (125 g/ha) and imidachloprid 17.8 SL (150 ml/ha). is one of the most damaging of biotic stresses that confront this crop. Kawada, K. and T. Murai. The studies on the relative occurrence and abundance of mustard aphid, Lipaphis erysimi (Kalt.) MATERIALS AND METHODS The aphids were cultured on greenhouse grown radish plants. This could also allow identification of novel target genes for development of RNAi-based aphid control methods. Of those aphid species, Baker (2015) lists 21 as occurring in Britain 4. Chemical control of mustard aphid with newer and conventional insecticides. 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. with combination of … Blackman & Eastop list 18 species of aphid as feeding on those 2 species, and all Raphanus worldwide, and provide formal identification keys Then in mid-October 2018 we found colonies of wild crucifer aphid on seed heads of hedge mustard (Sisymbrium officinale, see picture below). Large aphid populations can affect leaf size and yield. Mustard aphid, Lipaphis erysimi (Kaltenbach) is a major constraint in increasing the yield of rapeseed-mustard crops in India. (Show British list). This aphid is globally distributed, located in all … 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).

The infected filed looks sickly and blighted in appearance. Krishnaiah, K. and N. Jagan Mohan. It lives on the undersides of leaves as well as on inflorescences, young shoots and growing points. is very devastating. The antennal terminal process is 0.8-1.15 times times the length of the siphunculi (cf. Mustard aphid: Lipaphis erysimi. Our particular thanks to Roger Blackman for images of his clarified slide mounts. We have used the keys and species accounts of Blackman & Eastop (1994) and Blackman & Eastop (2006) supplemented with Blackman (1974), Stroyan (1977), Stroyan (1984), Blackman & Eastop (1984), Heie (1980-1995), Dixon & Thieme (2007) and Blackman (2010). Comparative efficacy of insecticides against mustard aphid, Lipaphis erysimi (Kalt.). Potential transcripts for host selection, detoxification, salivary proteins and effectors, molecular chaperones and developmental genes were identified. BSH 1 and Indian mustard, Brassica juncea cv. Mustard aphid, Lipaphis erysimi (L.) Kaltenbach is a perpetual annual threat in the cultivation of rapeseed- mustard (Brassica spp.) (Show British list). Blackman & Eastop list 15 species of aphid as feeding on those 3 species, and all Sinapis worldwide, and provide formal identification keys The losses in yield by mustard aphid were 66-96% (Singh and Sachan, 1997). Common Name. Efficacy of newer insecticides was studied against mustard aphid, Lipaphis erysimi (Kalt.) . 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. L. erysimi is a serious pest of mustard in India. Response of mustard aphid, Lipaphis erysimi (Kalt.) The body length of adult Lipaphis erysimi apterae is 1.4-2.4 mm. (2008). 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.
