Khan, A.H. | Afzal, M.
It has been shown that the principal factor in natural cross-pollination of cotton was the insect and that wind pollination does not take place in Lyallpur. Three species, Apis dorsata Fab., Anthophora confusa Smith, and Elis thoracica Lepel, were the prinicipal pollen carriers. The insects usually preferred to stay in the same cotton field, and in the case of sorghum barrier the few exceptions preferred to cross through the barrier rather than above it.
