Dispersal and orientation of sterile ceratitis capitata and Anastrepha ludens (Tephritidae) in Chiapas, Mexico
(1) Six releases of sterile Mediterranean fruit-fly (Ceratitis capitata (Wiedemann)) and one of Mexican fruit-fly (Anastrepha ludens (Loew)) were made in coffee and mango plantations in Chiapas, Mexico. Traps were arranged in a regular array around the release point; data were treated to produce standard and 95% confidence ellipses of daily fly positions. (2) In all cases mean fly position moved significantly from the release point indicating drift of the released population; most movements were towards the north and east, the direction of prevalent daily winds. (3) The pattern of trapped flies was significantly different from a circular distribution on 23 out of 37 experiment days and orientation sometimes changed markedly from day to day. These translational and rotational movements of the released flies appeared to be independent of each other.
