A. citricola is quite susceptible to drought conditions ( Yoder and Hoy 1998 ) , and this could have contributed to its reduced ability to suppress leafminer populations during some recent dry springs in flush intervals 2 and 3 . Spirea aphid - Aphis citricola is found in every state on spireas . Oct 1997 ) densities of citricola were evaluated by collecting 10 leaves from the northeast quadrant of each tree and counting the number of live 1st instar nymphs . When A. citricola was introduced into Florida from Australia , it was reported to disperse rapidly , up to 300 km within a year ( Pomerinke and Stansly 1998 ) .
