ABSTRACT
The present investigation on population density of Myzus persicae Sulzer (Hemiptera
:Aphididae) on six varieties of cabbage (Pluto, NS 183, Green Express, Pan 1181, Mohar F1, Rare Ball) were conducted at Central Research Farm, Gayeshpur, Bidhan Chandra Krishi Viswavidyalaya, Nadia, WB. Result from first year in first crop highest population 574.30aphid/plant was recorded during 6th standard week (SW) and second crop 380.80aphid/plant was recorded during 10th standard week. Second year observations, maximum population 548.37 and 448.57 aphid/plant were recorded from first and second crop during 6th and 12th standard week respectively. Minimum population 7.77 and 21.47aphid/plant observed during first standard week from both the years respectively and lowest population 87.83aphid/plant was observed during 16th standard week of first year and 110.73aphid/plant was recorded during 17th standard week of second year. From the above observation it can be said that all the varieties were highly susceptible in response to the aphid infestation. Among the varieties Pluto and Pan-1181 were more susceptible.
Key words: Population density, Aphid, Myzus persicae, Cabbage.
