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.

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.

Different Levels

An experiment was conducted to find out the influence of three irrigation levels (no irrigation, one irrigation and two irrigation) on four mustard varieties (Tori- 7, BARI Sharisha-6, BARI Sharisha-9 and BARI Sharisha-8). The non-irrigated plots had highest aphid population (34.96/plant) and lowest (11.16 aphids/plant) in two irrigation. The variety BARI Sharisha-8 showed lowest (5.34 aphids/plant) aphid infestation and its yield was highest (2.05 ton/ha). Interaction effects indicated that the crop escaped from the aphid incidence in the variety BARI Sharisha-8 irrigated 2 times and produced highest yield (2.37 ton/ha). The differences in the aphid population at three irrigation levels affected the yield contributing characters and it was negatively correlated (correlation coefficient value ‘r’ ranged from -0.91 to 1.0).Bangladesh J.

Varietal Preference

Context: Lipaphis erysimi have different type of preference to settle on different varieties of mustard. Pest preferential movement is important for ecofriendly pest control.Objectives: The aim of this study was to determine the L. erysimi resistance varieties of mustard to get more yields by lower cost and avoid most aphid infesting varieties for higher costMaterials and Methods: Two criteria were used to determine the varietal preference of L. erysimi, viz. (i) dispersal of aphids by cutting the base of host plants and enforce to settle on different varieties of three species of Brassica under free choice conditions, and (ii) suitability of those varieties based on the aphid infestation in the field crop condition at same season. Results: The preferential movement of L. erysimi on ten varieties of Brassica showed significant differences (P<0.01). The variety, Bari sharisa-6 showed highest (90.00 ± 7.21) aphid settlement followed by the variety, Rai-5 (89.00 ± 5.69). The variety, Bari sharisa-10 showed lowest (10.00 ± 0.58) aphid settlement followed by the variety, Bari sharisa-11 (19.00 ± 3.61). Naturally infested aphid population on first sowing date was recorded highest (2.1 ± 0.79) on the variety Bari Sarisha-8, followed by Bari Sarisha-6 (1.93 ± 0.88). The lowest (0.19 ± 0.09) number of aphids recorded on Bari Sarisha-12. In second sowing date, Bari Sarisha-7 showed highest (19.5 ± 6.51) aphid population, followed by Bari Sarisha-8 (15.42 ± 5.72). The lowest (1.2 ± 0.38) aphid population found on the variety, Bari Sarisha-11. In third sowing date, highest (14.69 ± 5.69) number of aphids was recorded on the variety, Bari Sarisha-6, followed by the variety, Sonali-75 (14.48±4.74). Lowest number (6.06 ± 2.30) of aphids was found on the variety, Bari Sarisha-12. In the fourth sowing date, highest (15.54 ± 5.72) aphid population recorded on the variety, Bari Sarisha-8, followed by Bari Sarisha-7 (14.39 ± 5.70); and the lowest (4.41 ± 1.75) number of aphids recorded on the variety, Bari Sarisha-9.
