The distribution of adult coccinellids depends on
both the location and abundance of prey and on specific habitat
preferences that may be independent of prey (Blackman, 1967b;
Hodek, 1993; Honeˇk, 2012; Leather et al., 1999). We infer that
pistachio trees represent an amenable habitat for A. bipunctata
adults, especially when infested with psyllid nymphs.
