Distribution of boll weevil (Anthonomus grandis Boheman) eggs within cotton plants
The natural distribution of boll weevil eggs (Anthonomus grandis) within cotton (Gossypium hirsutum L. race latifolium Hutch.) plants was studied throughout the season on the CNPA/EMBRAPA Research Farm at Surubim, Pernambuco, Brazil. The results obtained indicate that boll weevil females prefer to lay proportionately most of their eggs in medium squares (? 3 mm and < 6 mm in diameter) from the beginning to the end of cotton season, and they deposit most of the eggs on the upper half of the plant. It is suggested that sampling cotton plants on these sites could be important for boll weevil research purposes and management decisions.
