Behavioural responses of Anopheles gambiae sensu stricto M and S molecular form larvae to an aquatic predator in Burkina Faso

Table 3 Rotated factor patterns testing behavioural responses of Anopheles gambiae M and S larval instars (2^nd, 3^rd and 4^th) to the presence of the predator, A. jaczewskii

	Principal component (eigenvalue)
Variables	PC1 (2.34)	PC2 (1.99)	PC3 (1.51)
Bottom	-0.16	0.22	-0.11
Browsing	0.05	-0.18	-0.60

Surface	-0.97	-0.05	0.07
Thrashing	-0.14	0.03	-0.86
Wall	0.98	-0.12	0.15
Interpretation	Surface vs. wall	Resting vs. filtering	Thrashing, middle and browsing vs. other

Values greater than 0.40 (in bold) represent strong factor loading contributions for each principal component (PC). A large positive score on PC1 indicates that larvae spent more time at the wall of the container and a large negative score indicates that it spent more time at the surface. PC2 indicates that more time was spent resting as opposed to filtering. Negative scores on PC3 indicated that larvae allocated more time to thrash in the middle and to browse as opposed to other behaviours
