Buds which have fallen to the ground very rarely have maggots in them. This is because the maggots leave the buds to go into the ground for the purpo-e of iiu[)ating and developing into the adult winged insect. Infested cotton flower buds can geuerallj' be recognized on the plant, because the bracts surrounding the bud always ' flare,' that is, instead of retaining their normal position close around the bud, the}' are turned back so as to fully expose the bud. The attack in 1907-8 was very .severe. Cotton in all parts of Antigua suffered severely. Wild cotton was found to be infested, but whether this is the natural food plant from which the flower-bud maggot has spread to the culti- vated cotton is not yet known. The maggot in the bud is attacked by parasitic insects which probably exert a great influence in checking the outlu'eak of this Fig. 3. Confurhiin i/i/.isi/pi'i ; larva or maggot (enlarged). It was noticed that the first attack of this pest appeared in December 1907, that early planted cotton escaped with nuieh injury than the late planted, and that the loss WHS greater also on the heav)- damp soils, and in fields where there was a tendency to a rapid growth of weeds. No remedial have given anj' definite results. The attack subsided naturally during March and April.
