Detail:

To minimize bollworm infestation in cotton (Gossypium hirsutum) crop, the corn (Zea mays) grain is scattered and spread in the furrows of the cotton field. The birds like sparrows and pigeons come to eat corn grains, and get attracted to the bollworms in the cotton field. These birds smell the presence of bollworms, get attracted and the bollworms are destroyed.

PAS 1:

"Crop rotation this is another cultural control measure widely adopted by most cotton farmers in Zimbabwe. Cotton is rotated with other crops in order to breakthe life cycle of pests and diseases. Crop rotation is effective on red and pink bollworms which have narrow host ranges. African and spiny bollworms arepolyphagous, so will not be affected by rotations. Pink
bollworm: While someinsect pestsare aggravated by rotation others are suppressed with rotations. The pink bollworm only can survive on cotton squares and bolls, thus large scale rotation out of cotton has a dramatic impact on this pest (Blasingane et al., 1991). Rotations crops used include maize,wheat andsoyabeans." [Mapuranga, Rangarirai&Chapepa, B. &Mudada, Nhamo. (2015). Strategies for integrated management of cotton bollworm complex in
