This study aimed to evaluate the quality of the aphid Myzus persicae (Sulzer), Lipaphis erysimi (Kaltenbach) and Brevicoryne brassicae (L.) as hosts for the parasitoid Diaeretiella rapae (McIntosh). Parasitization by D. rapae was higher on M. persicae than on L. erysimi and B. brassicae. The time of development of D. rapae from egg to mummy or egg to adult male or female were shorter on M. pers...

Wild crucifers namely Arabidopsis thaliana, Brassica fruticulosa, B. rugosa, B. spinescens, B. tournefortii, Camelina sativa, Capsella bursa-pastoris, Crambe abysinnica, Cronopus didymus, Diplotaxis assurgens, D. gomez-campoi, D. muralis, D. siettiana, D. tenuisiliqua, Enatharocarpus lyratus, Lepidium sativum and Sinapis alba along with five cultivated Brassica species including B. rapa (BSH-1)...

Management of Mustard aphid Lipaphis erysimi (kaltbach) using Bio-pesticides in field condition was carried out during Rabi 2022-23 at central Research SHUATS Prayagraj,UP, India. The management done 8 different treatments and benefit cost ratios were calculated. One spray is applied to protect the crop from mustard (Lipaphis erysimi) randomized block design with three replications. observation...

Rorippa indica, a wild crucifer, has been previously reported as the first identified plant in the germplasm of Brassicaceae known to be tolerant towards the mustard aphid Lipaphis erysimi Kaltenbach. We herein report the full-length cloning, expression, purification and characterization of a novel R. indica defensin (RiD) and its efficacy against L. erysimi. Structural analysis through homolog...

Aphids are major insect pests for crops, causing damage by direct feeding and transmission of plant diseases. This paper was completed to discover and characterize a novel insecticidal metabolite against aphids from soil actinobacteria. An insecticidal activity assay was used to screen 180 bacterial strains from soil samples against mustard aphid, Lipaphis erysimi. The bacterial strain H008 sho...

The effect of nine surfactants on the activity of oxytetracycline hydrochloride (OCT) was investigated against Lipaphis erysimi Kalt feeding on cabbage plants. All the surfactants, except Emulgator EL and Emulgator IP, at 0.1% increased the efficacy of OTC at 0.25% and the maximum reduction of 83.93% in fertility was observed for the combination OTC+Arkopal N-110. The nymphal development was de...
