Abstract: The larvae and adults of coccinellids were known to detect their preys either by olfactory or visual stimuli. Through Y-tube olfactometer studies it was observed that
C. montrouzieri showed a maximum orientation (74.0%) towards
P. citri and the lowest response (57.8%) was towards
Phenococcus sp. The olfactory response of
C. montrouzieri was more (81.0%) towards prey with host leaves (guava) than prey alone (74.0%). Similarly, through four arm olfactometer studies, it was observed that 45.67 per cent of
C. montrouzieri adults oriented towards
P. citri while it was 21.0 and 14.33 per cent for
M. hirsutus and
Phenococcus sp respectively and also about 44.33 per cent of
C. montrouzieri adults oriented towards
P. citri + guava leaves while it was 22.33 and 16.67 percent for
M. hirsutus+ mulberry and
Phenococcussp + cotton leaves, respectively. Through Pettersson olfactometer, it was observed that the time spent by
C. montrouzieri adults with
P. citri was more (4.10 min) when compared to
M. hirsutus in the opposite arm (3.08).
