Weather Parameters

Lipaphis erysimi (Kalt.) infestation on mustard account for significant yield losses in India. Experimental data from sixteen years were used to study the role of weather on the incidence and development of mustard aphid. Temperature was found to regulate the aphid population build-up and arrival . Weather parameters before one week from aphid population observation contribute higher effect than of the same date, two week prior and three week prior observation. In the present investigation regression equation between aphid incidence and using previous week’s weather data could be used for formulating the forecasting model for L. erysimi, and for taking control measures.

Functional Relations

Mustard (Brassica juncea L.) production in India suffers from aphid, Lipaphis erysimi (Kaltenbach), infestation considerably. Role of weather on the incidence and development of mustard aphids was assessed from experimental data from six north Indian locations. Aphid appearance and population build up was found to be regulated by temperature and time to attain peak population was relatively short in warm humid climates than in cool climates. Aphids appeared generally when the accumulated thermal time ranged between 810-847 and diurnal temperature range had a key role on the pest build up. Functional relations developed from the present study between aphid incidence and peak population using previous weeks weather and pest data for majority of the locations could be used for taking of any prophylactic/control measures. Projections on aphid population in future climates using generated weather variables indicated that warming may not increase aphid population at all locations uniformly.

Field studies were carried out to evaluate the efficacy of four new generation insecticides along with a botanical against mustard aphid (Lipaphis erysimi Kalt.) and their toxicity to coccinellid beetles and foraging honeybees during 2014-15 at Bangladesh Agricultural Research Institute (BARI), Gazipur, Bangladesh. Buprofezin 40 SC was found to be the most effective against aphid offering the lowest aphid population (1.56/ top10cm central twig) at 7 days after spraying (DAS) which was statistically identical to Diafenthiuron 500SC (1.85/ top10cm central twig). Among the treatments, Azadiractin 1EC appeared to be safest to coccinellid beetles and foraging honeybees because it recorded the highest number of beetle (7.50 /5 plants) and honeybee (9.64 /plot/5 min) population at 7 DAS, although honeybee population did not vary statistically with that of Buprofezin 40 SC and Lufenuron 5EC treated plots. Indoxacarb 145SC was found to be the most toxic against honeybees. However, the highest yield was obtained from Buprofezin 40 SC (1.57 t ha-1) treated plot although this was statistically identical to that Diafenthiuron 500SC (1.52 t ha-1) and Azadiractin 1EC (1.48 t ha-1) treated plots.Bangladesh J.

AbstractLipaphis erysimi (L.) Kaltenbach (Hemiptera: Aphididae) is one of the most important pests of brassica crops, mainly causing losses due to sap sucking, toxin injection and viral transmission. Knowledge about the main natural factors that regulate populations of this pest, as well as its critical mortality stage, is crucial for the development of integrated pest management of L. erysimi. Here, we determined the critical stage and key mortality factors for L. erysimi in cabbage using an ecological life table. Causes of mortality at each stage of L. erysimi development were monitored daily in the field for seven seasons. From the experimental data, we determined the key factor and critical stage of mortality through correlation and regression analyses. The nymphal stage, especially first instar nymphs, was critical for L. erysimi mortality. The key mortality factors were, in descending order of importance, physiological disturbances and predation by Syrphidae, Coccinellidae and Solenopsis ants. Therefore, control measures should target early stages of L. erysimi and the use of cabbage cultivars that have negative effects against L. erysimi may be a promising strategy for its management. Our results may be useful for plant geneticists who could develop new cabbage cultivars based on these findings. In addition, conservation measures of the main predators of L. erysimi may contribute to the natural control of this pest.

Among the various treatments evaluated for their bio-efficacy against mustard aphid on Indian mustard during 2011-12 and 2012-13 at CCS Haryana Agricultural University, Hisar, the spray of Dimethoate 30 EC @ 1 ml/l followed by Verticillium lecanii @ 108 CS/ml was proved to be the best treatment with pooled mean aphid population of 4.5, 3.25 and 1.65 aphids/plant as against 22.0, 24.0 and 26.0 aphids/plant in the control after 3, 7 and 10 days of treatment, respectively. The pooled mean seed yield was also maximum (1485.0 kg/ha) in this treatment as compared to control (1305.0 kg/ha).The treatment was found on par with spray of dimethoate @ 1 ml/l followed by Coccinella septempunctata @ 5,000 beetles/ha with pooled mean aphid population of 5.0, 4.0 and 2.0 aphids/plant after 3, 7 and 10 days of treatment, respectively and pooled mean seed yield of (1470.0 kg/ha). But the cost benefit ratio was maximum (7.25) in treatment dimethoate followed by C. septempunctata and NSKE @ 5% followed by C. septempunctata @ 5,000 beetles/ha (6.68). Thus, entomopathogenic fungi like V. lecanii or NSKE along with release of C. septempunctata can be used as alternative measure to manage mustard aphid instead of solely relying on insecticides.

Mustard aphid, Lipaphis erysimi Kalt., is the key insect pest of crop Brassicas causing significant reduction in crop yield. In the present study, widely grown Brassica cultivars RLC-1 (Brassica juncea) and GSC-6 (Brassica napus) were treated with elicitors salicylic acid (SA) and jasmonic acid (JA) at 0.5mM and 1mM concentration via foliar spray (given at 40 and 60 days after planting (DAP). Their effect was evaluated in terms of total soluble protein content and activities of defense proteins (peroxidase, protease inhibitor, polyphenol oxidase, amylase inhibitor and lectins) in relation to aphid infestation in leaf tissue. SA and JA application caused significant increase in activities of defense proteins as well as total soluble proteins. JA at 1mM concentration was most effective in both Brassica cultivars. The 2nd foliar spray gave a booster response. The aphid population/plant reduced significantly in both the cultivars with JA as well as SA. POD and PPO registered negative correlation with aphid population count. SA and JA foliar applications seemed effective against mustard aphid through positive modulation in activities of defense proteins.

Effectiveness of Biocontrol Based IPM Modules Against Lipaphis Erysimi Kaltenbach (Hemiptera: Aphididae)Rapessed and mustard are important oilseed crops in India. The vulnerability of the crop to mustard aphid,Lipaphis erysimiKaltenbach is the main bottleneck in successful cultivation of this crop. In order to use insecticides at a minimum level, effectiveness of different Integrated Pest Management (IPM) modules were tested under field conditions. The module (NSKE +Chrysoperla carnea) proved most effective in reducing the aphid population in terms of socio-economic and environmental values.

The Bio-efficacy of eleven plant extracts namely viz.Neem Kernel; Rhizome of Ginger; Leaves of Datura, Gajarghas, Harsingar, Oak and Latjeera; Bulb of Garlic and Onion; Flowers of Chrysenthemum and Fruits of Chilli in the concentration of 5 percent and imidacloprid @ 40 g ai/ha was tested against mustard aphid, Lipaphiserysimi and their effect on D. rapae and Coccinellid beetle were tested in the Department of Entomology, College of Agriculture, Gwalior (M.P.). All the tested plant materials and imidacloprid @ 40 g ai/ha were effective significanty in reducing the aphid population over control.The aphid population in treated plots ranged from 7.2 to 40.0 as against 85.4 aphid/twig in untreated control. Among the plant material, three sprays of Neem Kernel were found most effective followed by three sprays of chilli fruits.All the plant extracts were found significantly safer to D. rapae and coccinellid bettle in comparision to insecticide (imidacloprid).
