Reagents were unopened before the start of this study.
Unopened inflorescence buds were removed at this stage and the number of flowers which received assisted pollination recorded.
A further important fact is that a diet of unopened bolls leads, in general, to a high mortality with prolongation of the stadia.
Additionally, we completely covered 3-5 unopened i nflorescences of the eight female trees with mosquito netting (mesh size: 1 mm) to test for apomixis.
Not until the fourth instar was reached did nymphs thrive satisfactorily upon unopened bolls.
Young unopened leaves (approximately 100 mg) were harvested from each plant.
The mortality amongst nymphs fed on unopened bolls of large size must therefore be due to difficulty in getting at the food.
Boll weevils are small beetles that infest cotton plants, damaging them by feeding on the seed pods and unopened cotton flowers.
