Experiments were conducted at Yezin Agricultural University Farm during May 2011 to February 2012 to examine the effect of sowing dates on sucking insect pests in black gram (Yezin-4). A Randomized Complete Block design (RCB) was used with five treatments (different sowing dates) and four replications. Treatments were five sowing dates (T1 - 14 May, T2 - 21 May, T3 - 28 May, T4 - 4 June, T5 - 11 June in 2011 wet season) and (T1 - 29 October, T2 - 5 November, T3 - 12 November, T4 - 19 November, T5 - 26 November in 2011 dry season).
